Energy News - 3Issue 12

Dear Reader,Last year was a very dynamic one in the energy business. Market liberalizationcontinued, causing major energy price fluctuations through demand-supply pricing. InEurope oversupply radically reduced electricity prices, while in California lack ofpower caused a price surge that distributors were not able to pass on to consumerprices, which are still regulated. I guess we must simply get used to the ‘stableinstability’ of the free markets.

Despite the high oil prices, Wärtsilä performed well in the heavyfuel oil power plant business. We recorded sales of 1574 MW inour traditionally strong markets like India and Central America,while substantial sales and deliveries were also made to newmarkets like Turkey, thanks to our flexible, competent organizationand in-house expertise in financial engineering. Our ability todeliver complete 100 MW+ plants in remote areas in just 6 to 8months is a highly valued advantage for investors in these turbulenttimes. Asian recovery from the economic crises is already visible inthe project list and a few orders have already been receivedrecently.

Major changes in energy prices in our traditional gas power plantmarket, Western Europe, reduced demand for gas CHP plants. Thisperiod of low demand seems to last for some time, and will onlyend when oil/gas prices go down or the growth in demand forelectricity has reduced the overcapacity adequately. The drop ingas power plant deliveries to Europe has been balanced recentlyby major orders in the USA and this year looks indeed much brighter.

Trading of gas and electrical power will be a growing business in the future. Largecompanies willing and able to take the fuel-to-electricity price risk also with gas andoil will have a strong position in the energy game. Another interesting new ‘product‘ ispower quality; ensuring consistent voltage and frequency to power consumers. Wecan see the market dividing into segments such as power generation, energy trading,transmission & distribution and power quality.

Through improved focus on specific customer needs, Wärtsilä will continuedeveloping its products and services to serve the new, more dynamic energy marketswith the most competitive solutions.

Pekka AhlqvistGroup Vice PresidentPower plants

The US energy market andparticularly the Californiaenergy crisis have hit theheadlines in recent months. At acursory glance, it appears thiscrisis was caused byderegulation of the electricitymarket. A closer look, however,reveals that market forces inplace for some time are onlynow surfacing through acombination of timing. Couldthe same thing happen inEurope? And what can be doneto prevent it?

The US electricity market isexperiencing an overall shortage ofgeneration capacity, illustrated inparticular by the recent Californiabrownouts and rolling blackouts. Atthe same time, the USA has turnedtowards natural gas as a resourcefor its peaking electric generation.This is resulting in higher and morevolatile prices, lower reliability andlower quality of electricity, andrecord high prices of natural gaswhich make generation more of atime-of-use operation, rather thanan 8760 hour per year application.

Since 1970, the average retailprice of electricity has increasedfrom 1.7 cents/kWh to 6.7

cents/kWh in nominal US dollars.Levellized in 1999 US dollars, therate has been reported to multiplymany-fold in real-time pricing overthe past 12 months in spot marketareas. By 2005, projections areexpected to decrease to 6 cents andby some 10 % by 2020 owing tocompetition among electricitysuppliers. But the real-time pricingisn’t supporting projections becauseof the poor availability andreliability of power.

The natural environment inwhich electricity is being generatedisn’t co-operating either. Hightemperatures in the summerdecrease the efficiencies andcapacities of gas turbine plants. Lowrainfall is threatening thehydropower supply. Natural gasstorage is at a minimum because ofthe dramatic increase in demand fornatural gas during cold winters andthe trend towards gas-firedgeneration.

At the same time, generationcapacity has not been increasing atthe same rate as demand.Historically, electricity demand hasrisen from 1400 TWh/year to3000 TWh/year today, and isexpected to be 4800 TWh by 2020.Current reserve margins for the

nation are less than 10 %, which isdeemed critical to meet a peakgrowth demand exceeding 3 % peryear; in the mid-1990s that reservemargin met a growth demand ofless than 2 %.

These reserve margins are notevenly distributed throughout theUSA, either. In major transmissionpools such as the Western (i.e.California) and the Eastern (i.e.Northeastern US) Interconnectionterritories, the reserve margin is lessthan 5 %, which is not enough tokeep the lights on during summerpeak periods.

While capacity reserves are lowin highly populated areas, andprices are correspondinglyincreasing, transmission constraintsare also an issue. In North America,the major transmission grids aredistinctly divided into regions:Western, Eastern, Quebec andTexas. These transmission systemsare not designed to transport poweracross each other, and within thoseregions serious bottlenecks areoccurring. Overall, high-voltage ACtransmission mileage in the USA hasincreased by only 9658 miles(6.7 %) from 1990 to 1999, andplans for expansion until 2004 areonly 5461 more miles. Many experts

Today’s energy crisis

say that this will lead to a need forpower closer to the end source ofneed, if more transmission lines arenot constructed.

Call to actionDeregulation and the factorsmentioned above have significantlyinfluenced the recent developmentof US market generation capacity. Acall to action has been issued, forshort-term and longer-termsolutions. In the short term,legislation has been passed to easethe process for fast, environmentallycompliant capacity installation. Infact, gas turbine availability today isreported to be at a three-yearreservation level, due to the highactivity of gas power plantinstallations. In a longer-term view,transmission improvements arebeing planned and deregulationincentives are being re-evaluated.

Comparison with the EUIs the crisis an isolated occurrenceor could this happen outside theUSA?

Some may argue that thisoccurrence is not unique to the USAitself, although certainly the timing ofall factors occurring today is unusual.Indeed, a combination of any two of

the factors mentioned above in anewly deregulated environmentcould at the very least set off amarket fluctuation in pricing. Themajor contributor to such a crisisseems to be a decrease in generationreserves, coupled with the inabilityto transmit electricity from state tostate or region to region.

This may be comparable to thetransmission system and constraintsin Europe. The states are analogousto countries within the EU withrespect to size. Similarly,transmission lines are constructed inan isolated pattern, with some butnot many interconnections betweennations (states), creating electricitytrading pools, or regionaltransmission organizations (RTOs).This limitation to cross RTOs ortrading pools drives generationrequirements up, so that reservecapacity must be maintained forpeak periods within each specificnation (state).

In a free market, prices decreaseas generation overcapacityincreases, which has been the casein Europe overall. Decreasing pricesdiscourage development of newpower plants, until prices rise toinvestment levels again. This is thenatural law of a free market, if

environmental policy allows. Hence,it would be logical that at somepoint the latest phases ofnon-construction in Europe willgenerate a price increase, as reservemargins, power quality andreliability decrease. This willencourage a new phase ofconstruction, and so the cyclebegins again as long as the integrityof transmission lines within thenations are upheld, andenvironmental policy is consistentwith the capabilities ofcommercially available technology.Should either of these fall by thewayside, there are elements whichcould contribute to Europe’s own‘Perfect Storm’.

Seeking solutionsAnalysts expect a diversification ofpower resources and a trendtowards more highly decentralizedand distributed generation. Thecosts and time required for majortransmission upgrades, along withthe public attitude of NIMBY (“NotIn My Back Yard”), have shown thisto be consistent with the trending ofdiversified power. Overall, it isexpected that an energy portfoliocomprising electricity transmittedfrom large central power plants

combined with medium-sized,highly decentralized energy andretail distribution will increase theoverall reliability of the system,keep cost peaks within manageablelevels, and be more environmentallyresponsible.

Wärtsilä is working to provideanswers to these challenges byoffering pre-engineered, fast-trackelectricity generation systemsdesigned to meet the intermediateand peak energy requirements oftoday’s wholesale or retail markets.Gas-fired packaged systems basedon 10-50 MW blocks of power areavailable for standard deliverywithin 6-8 months. Due to theirhigh efficiency and relativeinsensitivity to ambient conditions(compared to gas turbines), thesecan be dispatched at a loweroperational cost, or strike-price, andtherefore financially meetintermediate peak requirements.The Wärtsilä plants are gas-fired,high efficiency, environmentallyadvanced solutions that Wärtsilä hashad experience in installing inEurope and throughout the worldfor many years.

The extraordinary circumstancesthat are occurring today in the USAare not an isolated fluke, but neitherare they an insurmountable set ofproblems. Steps to create short- andlong-term solutions are under waywith increased coordinationbetween federal government, states,industry and the public. AndWärtsilä is working to contribute tothat effort with responsive energysolutions and services.

By summer 2001, Wärtsilä willhave sold over 530 MW of gas-firedpower power plants to alleviate thecrisis in California and throughoutthe USA. �

Peak shaving plantsfor two US municipalitiesWärtsilä’s new efficient peakingplants are designed to run off atransmission grid when demandfor electricity is at its highest.Two municipalities in the USArecently ordered peakingsolutions from Wärtsilä tomaintain service levels andreduce market risk.

Wärtsilä’s peak shaving plantconcept, marketed in the USA underthe name of PeakingPlusTM,represents the largest reciprocatingengine solution for the gas-firedpeaking market. Wärtsilä hasalready announced the first twosales of the new system. Thecontracts were signed withParagould and Kennettmunicipalities locatedapproximately 25 miles apart fromeach other in northeastern Arkansasand southeasternMissouri.

Paragould,Arkansas, a city of21,000 located 90miles northwest ofMemphis, Tennessee,operates amunicipal-owned utilitythat already provides thelowest cost for electricalservices in Arkansas and among thelowest costs in the USA.

The contract with Paragould’sCity Light Water and Cable (CLWC)calls for installation of three Wärtsilä34SG units with 18.4 MW contractedelectrical output. The units will bedelivered by 26 June 2001.

“Our customers already benefitfrom and expect low rates, soadding a peaking product to ourutility system made good economicsense,” said Larry Watson, GeneralManager and CEO of Paragould.“The new peaking plant will allowus to maintain our high level ofservice and low rates as wecontinue to take advantage of newtechnologies serving the peakingmarket."

Reduced risks in a volatilemarketThe second contract, signed byofficials representing the city ofKennett, Missouri, calls for deliveryof two Wärtsilä 34SG units. TheKennett Board of Public Worksoperates its own light, gas andwater facilities. Kennett is a city of11,500 located approximately 200

miles south of St. Louis and 100miles north of Memphis.

“Given the high summer peakingrates, the volatility of electricitypricing and the resultant brown-outsand black-outs, both of these

Wärtsilä customers wanted toreduce their own risks whilepositioning themselves to sell intothat volatile marketplace,” said TomCarbone, President of WärtsiläNorth America, Inc.

“They wanted not only to insurethemselves against fluctuation, butalso to profit from it on behalf oftheir customers. The new peak-loadsystem from Wärtsilä representedthe best solution for these twomunicipalities and their customers.”

Decisive advantagesFor both contracts, Wärtsilä waschosen for its low heat rates,contributing to low operating costs.Wärtsilä also offered the best valuethrough fast delivery times andcompetitive capacity costs duringthe hot summer peaking season.

Wärtsilä’s peaking plants aredesigned to run parallelwith the transmissiongrid when demand forelectricity is at itshighest. At 3.5 to 4.0cents per kWh

operating costs, theWärtsilä systems can be

activated earlier than otherpeak-load systems because they

are designed for higher efficiency.The system has low-pressure

gas requirements and no make-upwater requirements. Wärtsilämanufactures this peak powersystem in modularized 10 - 50megawatt units, for plants up to 200MW. They can be run efficientlyand cost effectively even forextended periods of time. �


What´s new


Meeting the world´s energy needs

Data colocation callsfor new solutionsThe explosion in mobiletelephony and data transmissionhas generated a new type offacility, Data Colocation Centres,which have demanding needsregarding main, stand-by anduninterrupted power supply.Power plants based on Wärtsilä200 engines and Wärtsilä gasgenerating sets are an idealsolution for the unique powerand air conditioning needs ofthese facilities.

Data transmission volumescontinued to skyrocket during theyear 2000, driven by the Internetand the increased number of mobilephone users. Data transmissionswitches and relays are sensitivepower consumers since users, andthat means all of us, will not tolerateinterruptions. So Internet ServiceProviders (ISPs), operators and

telecom companies have to securetheir power supply against allpossible threats.

Special facilities have been builtto answer this need. Called eitherData Colocation Centres, InternetHotels or Web Farms, they are thephysical location that holds theoperator’s switching equipment.Their size varies from 5,000 m2 upto 30,000 m2.

Such facilities are fully secured,with floor reinforcement, airconditioning, restricted access andpower back-up includingUninterrupted Power Supply (UPS)to avoid micro-cuts and to filter theelectrical supply. Space is rented ona square meter basis at high costthat gives the investors a shortpay-back time.

Until now, investors have beenannouncing aggressive rollout plansthroughout the world. The

colocation centres are located closeto optic fibre junctions and usuallynot far from a river, sea or ocean.Indeed, the most cost-effective wayto handle fibre optics is to placethem under water. The key cities fordata colocation centres in Europeare currently London, Amsterdamand Paris.

As dense as the sunAssuming that the New Economywould save energy when increasingand improving communications waswrong. Even though the powerrequired to create, process andtransmit a single bit is halved every18 months, the traffic of bits isincreasing at a much faster rate.

A large proportion of the poweris consumed by air conditioningand ventilation in evacuating theheat generated by the silicon chips.The surface of a Pentium processingchip, for example, has a higher heatdensity than the corona of the sun!With thousands of computers in thesame room, a great deal of heat isgenerated.

Consequently, this creates highpower density in one spot. Where atypical building would need 150 to300 W/m2 of power, a datacolocation centre needs anythingfrom 800 to 1,300 W/m2. A30,000 m2 centre, for example,requires almost 40 MWe.

The Wärtsilä solutionIt is standard practice to installdiesel-driven stand-by generatingsets and UPS systems to provideelectricity in the event of main

source failure, the UPS being usedas a ‘No Break’ for criticalconsumers. Batteries and rotaryflywheel are the energy source ofmost common UPS systems.

The stand-by market has typicallybeen controlled by ‘2 MVA’ gensetsuppliers, as they are usually called.However, the compact size of theWärtsilä 200 power plant offersobvious benefits for the followingreasons.

Highest power density in MW/m2

Rented space is the most valuableand profitable floor area forinvestors and therefore the size oftechnical facilities must be reducedto the minimum.

The Wärtsilä 18V200 is thebiggest high-speed generating set inthe world with the highest MW/m2

output. Easy to install thanks to its

integrated circuits, it offers fast andreliable starting as well as quickload pick-up. The W200 can deliverits full output in less than 20seconds from starting order.

The high unit output of theWärtsilä 200 allows the customer toinstall fewer units on a site, andsave space. As an example, a20 MW power plant shown belowwill save more than 30 % floor areacompared to a power plant withconventional 2 MVA dieselgenerating sets.

Black start capabilities –essential or useful insurance?There are not many powerstations in the UK with a trueblack start capability. Butspending that extra bit of capitalto ensure back-up for potentialsystem failure can save time andmoney. Medway Power Limitedin Kent, UK, has invested inblack start benefits.

Back-up generating sets for blackstarting a power plant used to becommonplace. These are lacking atmost plants today, partly fortechnical reasons, but more oftenon commercial grounds; the extracapital costs for black starting canbe prohibitive.

Plant and grid failures are few butpower companies and plant

managers need to bear in mind thataccidents and system failures dooccur. Without black starting,re-establishing the supply systemcan be difficult and severelydelayed. Investing in a secureback-up is essential to minimizingthe consequences of system failures.

What are black starts?Black start is the procedure forrecovery from total or partialshutdown of electrical supply in theNational Grid Company’s (NGC)transmission system and/or supplierdistribution network. Power stationsrequire an electrical supply to startup; obviously a station needsadditional power with sufficientcapacity to feed the unit’s auxiliary

equipment while the maingenerating plant is prepared foroperation.

The additional power source isusually provided by a smallerperipheral black start generatingplant, started from a battery or otherenergy storage device. Onceoperational, the power plant can beused to electrify part of its localnetwork and provide electricity forother plants within the area,enabling them to start-up.

When the transmission system ispartially or totally shut down, thegeneral principle of recoveryincludes re-establishing isolatedpower stations which create ‘powerislands’; these are then integratedinto larger sub-systems, which


eventually allows the re-instatementof the whole national grid. Electricalsupplies can be rapidly restored ifthis capability is established at anumber of strategically located sites.

Black start facilities must be ableto start up the main generating plantwithin an agreed period of time andwithout the use of external powersupplies. Furthermore, the blackstart must supply enough power torun auxiliary equipment at thepower station throughout an agreedstart-up period. The station as awhole must be able to provide atleast three sequential black starts toallow for possible tripping of thetransmission system during there-instatement period.

Medway, a criticalpower sourceThe black start facility at MedwayPower Limited provides security tothe southeast of England, enablingpower to be restored as a priority tothe Medway and Sittingbourneareas.

Medway, a 688 MWe powerstation, is one of a new breed of gasturbine combined-cycle plants.Based on the Isle of Grain in Kent,Medway is specifically designed touse natural gas or distillate oil asfuel. Two GE Frame 9 gas turbines,rated at 228 MW each, a 246 MWsteam turbine and two HRSG boilersform the basis of this power plant.The plant supplies power to theNational Grid.

As the main power source for theregion, it is vital that Medway’selectricity supply remains secure.For that reason, NGC has beenanxious to expand its contractportfolio of black start provisionfrom this new generation ofgas-fired power plants. As part ofthis expansion Medway Powerrecently signed an agreement with

NGC to provide such a facility at theplant site.

The proposal for the black startfacility at Medway Power looked atthree prime mover options: small,open-cycle turbines fired by gas oroil distillate; medium- andhigh-speed conventional dieselengines; or dual-fuel compressionignition engines running on gas oroil distillate.

The final choice, however, wasdictated by circumstances. Theavailability of a gas supply during ablack start situation could not beguaranteed because the main planthas an interruptible gas supply;therefore gas turbines were notsuitable for this purpose. Dual-fuelengines were considered butrejected because of fuel supplyproblems. The higher cost ofmedium-speed diesel enginesprohibited their use.

High-speed LFO enginesFinal equipment selection atMedway centred on high-speed,LFO-fuelled diesel enginegenerating sets. A Power Managerplant with six Wärtsilä 200 engineseach rated at 3.1 MWe were chosenafter tender, providing a total netelectric power output of 18.5 MWe.Power plant and engine flexibility,low lifecycle and capital costs werethe key tender requirements due tothe special nature of the plant.

The original design selection wasbased on four larger medium-speeddiesel alternators at 3300 Vdedicated to four particulardistribution circuits. Following therejection of gas turbines anddual-fuel engines, the dedicatedfour-engine, large-output solutionwas originally chosen because offault level limitations which wouldbe exceeded by synchronizing thefour units to a common bus-barprior to distribution.

However, Wärtsilä provided adifferent solution: generating andsynchronizing all generators to acommon bus-bar at 11,000 V beforestepping down through impedancetransformers to the 3300 Vdistribution circuits. Use of thecompetitive 1500 rpm, 3.1 MWeunits allowed the additional cost ofsynchronizing switchgear andtransformers, yet still providing anoverall cost saving.

This solution also offers muchhigher intrinsic availability. In theoriginal system based on fourdedicated engines, failure, ormaintenance outage, of one enginemeant that the full black startcapability was unavailable. Thesix-engine option synchronized to acommon bus-bar ensures that atleast five of the six will be capableof providing black start capability.

The generating sets are housed ina single-storey building (coloured asper the main station to softenenvironmental sight impact)

northwest of the main powerstation. An engine cooling system,consisting of a closed water systemwith radiators and cooling fans, is



also in operation adjacent to theblack start building.

Fuel supply for the black startplant is taken from the mainstation’s existing storage tank. Thetank has sufficient stock to supplythe main plant and its facility duringan emergency. But to illustrate theimportance of forward planning at ablack start facility, the engines havea separate fuel storage tank sizedfor eight hours continuous runningat full load.

Wärtsilä has also supplied a fullremote control and monitoringsystem, installed for automatic alarmcall, remote control, synchronizingand data logging of the plant fromthe station and local service depot.

Operation and maintenanceThe Medway black start facility wascompleted in November 1999.

On occasions when the back-upplant is needed at Medway Power,almost all other processes in thearea will be shut down and notproducing any emissions to the air.The priority at such times will berestoration of power supplies toessential infrastructure (e.g. sewageworks, pumping stations).

In the extremely rare occurrenceof a total grid failure, the NationalGrid will expect to restore itstransmission system withinapproximately eight hours. Theblack start facility will operate toprovide full load within 60 seconds

of start-up. In addition, underextreme circumstances, the facilitycan operate for up to 72 hourscontinuously. The digital controland synchronizing pioneered byWärtsilä allows a high-speed start,synchronizing and transient startperformance of the black start plant.

The National Grid requires thatthe black start plant shall be testedon a regular basis, to ensureoperating reliability and to testswitching systems. As a result ofcommissioning, regular testing andrequirements for other tests of themain power station, each of the sixunits has clocked about 250 startswithout experiencing a single startfailure.

In the planning stage of theMedway black start Power Managerplant it was envisaged that testingwould be carried out for amaximum of 200-250 hours peryear, on a weekly basis. A typicalweekly operation will be fourhours. All of the generators willsimultaneously operate during theseperiods. Timing of the maintenanceis determined by Medway Power tosuit the running of the main powerstation plant.

Medway Power is a good exampleof the importance of makingprovision for black starting agenerating plant and it seems areasonable insurance for manyapplications. It provides operationalflexibility in the event of main supplyfailure and should only add a coupleof percentage points to overall plantcost. Accidents can happen andtoday’s electricity supply industryperhaps needs to adhere to themotto ‘Be Prepared’.�

First power plant for Japan’snew energy market

Japan’s liberalization of the electricity markets atthe end of March 2000 opened up competition forpower generation facilities. Under a scheme aimedat the retail electricity market, power plantssupplying over 20 kV electricity to the grid are ableto supply electricity to their own customers via theutility grid.

Wärtsilä is the first company to supply newpower generation equipment to Japan’s newelectricity retail business market, having won acontract to provide a cost-effective and reliableenergy package to Hitachi Zosen Corporation.

Wärtsilä was able to meet the customer’srequirements because of the short deliveryschedule and the high efficiency of the primemovers.

Hitachi Zosen’s customer, the Ennet Corporation(established by Nippon Telegraph and Telephone,Osaka Gas and Tokyo Gas), is one of six operatinga retail licence in Japan. The power plant is thefirst to be built and developed exclusively for thenew electricity retail market.

The plant will be built in Ibaragi, Hitachi Zosen’sshipyard area, adjacent to two existing gas turbinepower plants (100 MW and 24 MW). The newPower Master plant is equipped with 3 x 18V32generator packages with a total output 21.9 MW.The plant will start commercialoperation in July 2001.

What´s new

Energy forTurkeyTurkey’s energy market is one of the country’s fastestdeveloping sectors. Annual demand for electricity hasincreased by more than 7 % during recent years andinstalled capacity and annual generation figures havetoday reached approximately 27 GW and 120 TWhrespectively. However, since consumption per capitaper annum is still as low as 1,800 kWh (compared to8,500 kWh in Germany and 17,500 kWh in Finland), thepotential for further growth in this market isconsiderable.

Turkey began to privatize its energy sector in 1984 bymaking basic legal changes. Many other laws havefollowed since and the most recent law, passed on 20February 2001, takes the energy market anothersignificant step towards liberalization.

The Turkish economy will decline by some 6 % in2001 and demand for electricity has decreasedcorrespondingly, but the downturn is expected to beshort-lived, ending by the end of the year 2002.Electricity demand is expected to continue increasing atleast over the next two decades without reaching worldaverage consumption/capita figures. It is believed thatthis can only be achieved by good co-operation withforeign investors and financial institutions. For thisreason lawmakers have always given majorconsideration to the terms and requirements ofinternational capital.

Autoproducers favouredSpecial attention has been given to the industrialautoproducer concept. Cogeneration, the most efficientand environmentally friendly method of generatingthermal energy is obligatory. Consequently, over 2,600MW of capacity has been installed so far by privateautoproducer companies.

The volume of autoproducer cogeneration in Turkeyis still small compared to short-term and mid-term largepower plant developments in this market. The newEnergy Market Bill together with the non-availability oflong-term Treasury Guarantees for Power PurchaseAgreements of Build-Operate-Transfer (BOT) projects,will make the energy market more dependent onautoproducer projects during the years ahead.

Turkish industry (textiles, food processing, mining,steel, petroleum, construction, paper) is in dire need ofmore energy and, very importantly, reliable powersupplies. At the same time these should be provided atcompetitive cost. This has provided plenty ofopportunities for decentralized power generation forindustry and small- to medium-sized power generationprojects by IPPs. Such power plants supply energyclose to customers, and also run on several alternativefuels such as gas, LFO, HFO, crude oil andOrimulsion®.

Over the years Wärtsilä has supplied 790 MW ofpower to Turkey, which is approximately 20 % of thetotal autoproducer market. When considering only

diesel engine based power plants Wärtsilä has a marketshare of approx. 68 %. Wärtsilä’s references in Turkeyare summarized in the map below.

In many of these references Wärtsilä has also playedan important role in structuring and arranging financingfor the projects.

The successful implementation and operation ofthese plants is a good reference for the projects underdevelopment with new potential customers of ourproducts. �

Wärtsilä power plant references in Turkey.

Wärtsilä is developing new ITtools and applying the latesttechnical advances for powerplant optimization and remoteoperation and diagnostics. Thekey words are system-wideintegration and compatibility.

Power, particularly co-generationand peak shaving, is increasinglygenerated by distributed powerplants. This trend is emphasizingthe importance of easy operationand management of power plants.Other priorities include lowpersonnel costs and high utilization,which places high demands on theautomation systems to ensureefficient operation, goodinformation on the power plant,good tools for plant management,and unmanned remote controlledoperation. Wärtsilä is at theforefront of this development withnew concepts for high availabilityand operation-focused plantautomation.

Wärtsilä has developed newpower plant IT tools to supportefficient plant operation in anumber of ways. They provide anenvironment where processinformation can easily be accessedand interpreted to allow plantoperators to take the correct actionimmediately and proactively,thereby improving the availability ofthe plant. They also enable moreefficient plant operation by enablingremote control. And they provideaccess to real-time plant data tosupport better decision-making.

The Wärtsilä Operator’sInterface SystemTraditionally, the most importanttool for process supervision andcontrol has been the operator’sinterface system, or HMI (forHuman-Machine Interface). Thisprovides process visualization, datatrending, alarm handling and eventlogging.

Proper design of the operator’sinterface is crucial to enable theoperator to take correct action when

confronted with process problems,and to correctly determine thesource of the error in order todeploy the maintenance team tocorrect it. Even if all possibleinformation was available, theoperator could still take incorrectaction and draw erroneousconclusions if the information is notpresented in the right way. Again, ifthe system does not present the rightinformation, it may be impossible todetermine the source of the problem.

Wärtsilä has perfected itsOperator’s Interface System, calledWOIS, based on input provided byits own and customers’ operationand maintenance personnel. Theresult is a system that allows easyoperation and ensures correct actionif process problems occur.

The process interface is based ontraditional process visualizationtechniques but special care hasbeen given to the design of thegraphics to ensure clearvisualization. The colours in thegraphics and the process elementsthemselves have been carefully


Optimizing performance

IT and automation fordistributed power production

selected for clarity. The datadisplayed and logged has beenselected to help personnel make theright operation and maintenancedecisions, based on Wärtsilä’s ownlong experience and expertise inpower plant operation.

WOIS also allows the operator toaccess various features in thecontrol system like powermanagement systems to optimizeplant operation. These systems alsoreduce the operator’s workload byautomatically controlling the plant.

WOIS ConnectThe move towards decentralizedenergy production has also createda need to operate a number ofsmaller plants efficiently with asmall workforce. This calls forunmanned plant operation wherethe operation and maintenancepersonnel, at least part of the time,are not present at the power plantduring the operation.

WOIS Connect service makes thispossible, alerting standbymaintenance personnel if problemsoccur. Personnel can then connectup to the power plant using aportable WOIS workstation and

investigate the situation. They canrestart the plant remotely if possible,or schedule a maintenance visit ifneeded. Supervision can also behandled from central controllocations, e.g. at night, when theplant is unmanned.

Wärtsilä uses the WOIS Connectservice to remotely maintain parts ofthe control system, and to remotelyassist customers with fault tracingand problem solving. This cangenerate substantial savings sincemany problems can be diagnosedand corrected in minutes instead ofdays.

The Wärtsilä InformationSystem EnvironmentThe support provided by HMIsystems is not enough to ensureefficient plant management today,although it is accurate for fastdecisions and deployment ofmaintenance if plant problemsoccur. Business managers also needtools to access plant operational andperformance data for commercialfollow-up, while maintenancepersonnel need tools to accuratelyanalyze the plant condition in orderto plan operation and maintenance.

Since it is not practically possibleto develop a tool that would coverevery need, a number of systems aretypically used for analyzing,reporting and managing the powerplant. A disadvantage, however, isthat systems and tools areheterogeneous, and not always ableto provide the right information atthe right time in order to supportefficient plant operation. Data formanagement reporting may bemanually collected and old.Maintenance personnel may have touse a number of systems andinformation sources to find thenecessary information. Different toolsand support systems are ofteninstalled in separate workstationsand programs are barely compatible.The result can be an operation andmaintenance environment where thenecessary data is not available in theright form, and therefore cannot beused correctly or efficiently.

An increasing amount ofinformation may also be unsolicited,exposing personnel to ‘informationoverload’, resulting in sub-optimaloperation.

Wärtsilä’s answer to theseproblems is the Wärtsilä InformationSystem Environment, or WISE. TheWISE environment is not a singleprogram as such, but a platform forintegrating various applications forplant information access. WISE alsoincludes a database for storage of allplant data. In its minimumconfiguration, WISE is supplied witha number of tools necessary forefficient plant operation. Theseinclude:

• Technical information such asmaximum, minimum and averagevalues of process measurements,presented on a daily, monthlyand yearly basis. This data is usedfor technical follow-up and canalso be used to evaluate theprocess condition.


• Production and consumptioninformation, like electricity andheat production, fuel and lube oilconsumption etc. This indicatesplant efficiency, for example, andis used for commercial follow-up.

• Information on the availabilityand reliability of the plant. Theinformation can also be sent toWärtsilä, which will provide theplant owner with a benchmarkingreport. This helps the owner tobenchmark his own performance.

• An electronic logbook where allstarts and stops are automaticallyentered together with the majorreason for the stop. In addition tothis information, the O&Mpersonnel can enter their ownnotes on the events. Thepersonnel can also add otherinformation to the system asgeneral information.

• A simple maintenance follow-upsystem, allowing, for example,maintenance managers to entermaintenance orders and tracktheir progress.

• Feedback to Wärtsilä can beentered into the system, and will

be used by Wärtsilä for furtherproduct development.

The WISE system is linked to theWOIS system. This means that theprocess element selected in WOIS isalready known by WISE, and

relevant information on that processelement is automatically displayedwhen using the various WISE tools.This avoids information overloadfrom unrelated and irrelevantinformation.

The WISE environment also offersa number of optional services andtools, such as:

• Process video supervision

• Engine diagnostics, provided bythe FAKS system, that performsengine and measurementanalysis, flagging for possibleproblems in the engine

• Maintenance management withthe MAMA maintenancemanagement system

• Electronic maintenancedocumentation, in the form of theElDoc documents.

These tools are operated asintegrated parts of the WISEenvironment applying the sameoperational principles. WISE therebyintegrates all the various informationand tools into a single, internallyconsistent environment allowingefficient access to information.

The WISE environment alsosupports data warehousing, makingthe data from the power plantdirectly available to business andmanagement systems. This givesplant and company managementdirect access to plant data, allowinginstantaneous access to technicaland operational reports. Likewise,data from a number of distributedplants can also be consolidatedautomatically.

In the future, WISE will alsosupport direct linking into Wärtsilä’se-business system. This will make itpossible to read new service letters,place spare part orders or use anyother services through the worldwide web.

WISE ConnectCustomers are today increasinglyinterested in optimizingmaintenance. It would make muchbetter economic sense to exchangewear parts just-in-time, when reallyneeded, instead of following a fixedmaintenance schedule, while someparts might still have usable lifetimeleft. To do this in a safe wayrequires more expertise andknow-how than can be provided byany program at site. To meet thisneed Wärtsilä has introduced aCondition-Based Maintenance(CBM) service, which offers theplant owner expert advice byWärtsilä on how to schedulemaintenance in the optimal way.

Since this service requiressubstantial information to betransferred to Wärtsilä forevaluation, the WISE Connectservice is used. WISE Connecttransfers plant operational data (aswell as e.g. feedback reports)automatically from the WISE system

at the plant to a central dataanalyzing facility at Wärtsilä. Expertsat this facility then analyze the dataand determine the necessary andoptimal maintenance of the plant tomeet the targets for efficiency andavailability. The customer willregularly receive reports on theplant status and necessarymaintenance, and if there is aservice agreement with Wärtsilä,maintenance personnel willautomatically be dispatched to thesite when needed.

ConclusionsWith its long experience of powerplant design, construction,operation and management,Wärtsilä is actively seeking newways to improve the operation andmanagement of power plants. NewIT tools for efficient operation ofdistributed power plants is oneexample of this development. Theclient can also rest assured that anew power plant will be equippedwith the best tools available, sincethe same tools are used byWärtsilä’s own operation andmaintenance teams when operatingpower plants. �

Grugliasco 2000Tri-generation*, cleanliness and paybackIndustrie Pininfarina startedindustrial operation of a WärtsiläPure Energy plant on 1December 2000. With NOx andCO levels below the German 1/2TA Luft, Grugliasco 2000 is thecleanest Pure Energy plant inoperation in Europe.

The Pininfarina group is awell-established automobile designand styling Italian company with aworldwide reputation. Pininfarina

group has an annual turnover ofEUR 700 million, 2500 employees,and annual production of some46,000 vehicles.

The company IndustriePininfarina SpA and its threefactories are dedicated to theproduction of the Alfa RomeoSpider and GTV, Peugeot 306cabriolet and 406 coupé, andMitsubishi Pajero Pinin 3- and5-door 4-wheel-drive vehicles.Industrie Pininfarina is a highlyflexible industrial complex,

dedicated to the production of smalland medium series ‘niche’ vehicles.

Upgrading the Grugliasco plantIndustrie Pininfarina’s factory inGrugliasco, close to Turin, handlespressing of structural elements,body shell assembly, corrosionprotection and vehicle spraying.The Grugliasco factory requiresboth steam (8 to 28 ton/hour of 28barG saturated steam at 230 °C) forthe spray painting process, and 125°C superheated water and cold water


Inside view

to control the temperature of thepainting lines and production units.

In 1995, Industrie Pininfarinachose Wärtsilä to design and build itsfirst power plant. This 3 MW PureEnergy plant was built around threeWärtsilä 175SG gensets. In 1999increasing production and the needto cut energy costs led Pininfarina toraise the efficiency of itstrigeneration* plant. One option wasto add a fourth Wärtsilä 175SG, butthere was a better solution withmore modern technology.

The project was subject tonumerous constraints:

1. The Industrie Pininfarina plantis located in a residential area ofGrugliasco city, and the closestneighbours are only 30 metres awayfrom the power plant. The noiselevel was not to exceed 50 dBA.

2. Emission levels were limitedfor the same reason and subject tothe strict requirements set by thelocal authorities, Commune diGrugliasco and Regione Piemonte.

3. For environmental reasons,Industrie Pininfarina decided in1998 to employ water-solublepaints. This technology requires anabsolutely constant temperature inthe painting lines.

4. Should thermal flows beinterrupted, the factory lines would

start to suffer production losseswithin 20 minutes. Hence thereliability of the power plant andability to rectify or neutralize theconsequences of any grid power losswere key elements in the decision.Another consideration was the‘penalties’ to be paid by IndustriePininfarina to the Italian State UtilityENEL if it made excessive use ofelectricity from the grid.

5. The old power plant had to beshut down during the civil work forthe new plant that was performedduring the factory’s annualshutdown in August 2000. Thecompletion deadline of 1 December2000 had to be respected in order to

avoid using electricity from the gridand paying high fees to ENEL.

6. Finally, the decision to launchthe Grugliasco 2000 plant programfollowed the logic of anyinvestment. The payback time hadto be minimized, and in nocircumstances longer than the targetachieved for the Grugliasco 1996installation.

Everything for nothing?The organization of the Grugliascofactory is the result of a 10-yearprogramme of continuousimprovement. From the beginning,Industrie Pininfarina and Wärtsilächose to integrate the trigenerationplant into the factory processes.

The partners studied no less thansix scenarios. The final choice ofWärtsilä 220SG gensets was madeafter detailed evaluation todetermine the optimum scenariofocusing on interfacing thetrigeneration plant with the factory.According to Industrie Pininfarina’sGiuseppe Caspii, the Wärtsilä220SG, with its advancedtechnology, provided optimumefficiency and lower emissionlevels.

The new plant was installedinside the existing thermal plant andcompletely integrated into the hotwater and superheated waternetwork. It is connected to both theabsorption chillers and a ThermalCogeneration Systems (TCS)post-combustion boiler. The latterrelies almost totally on heat transferthrough convection. RiccardoTebaldi at TCS stresses that thecombustion chamber of a TCSboiler operates at temperaturesmuch lower than conventionalboilers: 650 °C instead of 1200 °C,which produces less NOx than aconventional unit.


Mr Simone Dorigo, Grugliasco plantmanager

Mr Giuseppe Caspii, Head ofPininfarina production facilities *Trigeneration = The simultaneous generation of power, heat and cooling.

Examples of optimizationAccording to Simone Dorigo, theGrugliasco plant manager,co-operation with Wärtsilä duringcommissioning and start-up wassmooth. Careful planning ensuredthat Pininfarina incurred only theminimum of extra costs when theoriginal power plant was shutdown. One example of power plantoptimization applies to the constantflow of raw water in the process.Instead of using radiators to cool

the gensets, heat exchangers havebeen installed on the raw waterpipes. The higher temperature ofthe water after the exchangers doesnot affect the factory’s productionprocesses.

The production of cold water isanother example. Themanufacturing processes consumeless heat in the summer since thetemperature is higher. The surplusis used by absorption chillers toproduce cold water for the spray

painting processes and for otheruses. The production cost is lowerthan in the case of conventionalelectrically driven units. In winter,the heat is used to warm thecomplex. A third example is the useof a post-combustion system toproduce steam. Natural gas incogeneration plants benefits fromlow taxation in Italy. Like allreciprocating engines, the Wärtsilä220SG gensets reject a minorquantity of unburned fuel in theexhaust gases. The choice of apost-combustion system instead ofconventional steam boilers allowsthis fuel to be burnt as well, whichobtains a higher efficiency than withnormal boilers. This reduces thecost of gas dedicated to steamproduction and further improvesemission levels.

Trigeneration, efficiency andcleanlinessOperating a post-combustion boilerdepends completely on the

The Wärtsilä WECSautomatic genset control systemcontrols each cylinder individually,which guarantees constantly stablecombustion in the cylinders. Thepost-combustion process is alwaysperformed at the highest efficiency,ensuring that the reliability targetsset by industrial plants are met.

In terms of emissions Grugliasco2000 is one of the cleanesttrigeneration plants in Europe. ItsNOx levels are below 170 mg/Nm3,and its CO emissions as low as80 mg/Nm3 at 5 % O2 dry and belowthe strict German 1/2 TA Luft.

Industrie Pininfarina has obtaineda tailored Pure Energy plant fromWärtsilä. The kWh price of theGrugliasco plant has been halvedand Industrie Pininfarina is well setto achieve its objective of shortpayback time. �

Wärtsilä consolidatesits sales and projectmanagement incontinental EuropeWärtsilä intends to consolidate its sales andproject management organizations incontinental Europe to enhance operationalefficiency and customer service. The intention isalso to consolidate the organization of SulzerZ40 -type engine service and technologyactivities.

Power PlantsThe aim is to concentrate the design and projectmanagement organization for gas power plants attwo centres, in Vaasa, Finland and in Mulhouse,France. Today Wärtsilä has three gas power plantcentres: in Finland, The Netherlands and France.

Wärtsilä's established power plant expertise isbased on heavy fuel oil (HFO) plants, in whichthe company has achieved a market leaderposition in the world market. Concentrating theproject management of large gas power plantsin Finland would enable Wärtsilä to gaineconomies of scale to increase its market sharealso in big gas power plants.

Wärtsilä France manufactures high-speedWärtsilä 200 and 220SG diesel and gas enginesand therefore the natural location for the designand management of power plant projects basedon this technology is in Mulhouse.

These changes in the Power Plants divisionwould improve project design and managementby placing the expertise needed for them inlarger organizational entities. �

What´s new

Samalpatti fast-track Power Mastercompleted ahead of scheduleWärtsilä has constructed andhanded over a 105 MW PowerMaster plant in India in just 14months despite remote andimmensely challengingtopographical conditions. TheSamalpatti Power Project inTamilnadu, Southern India, wascommissioned in February 2001.

Samalpatti Power Corporation(SPC), an Independent PowerProducer (IPP) formed by ShapoorjiPallonji, Covanta Energy andWärtsilä Development & FinancialServices, contracted Wärtsilä tosupply a Power Master plant withseven Wärtsilä 46 engines on 6September 1999. Wärtsilä was givenresponsibility for the plant suppliesand services including erection andcommissioning.

A Power Purchase Agreement(PPA) signed in May 1998 betweenTamil Nadu State Electricity Board(TNEB) and SPC gave SPC the rightto build, own, operate and maintaina 105 MW LSHS/FO/alternate fuelfired power generating facility atParandalli Village in Tamil Nadu.Under the PPA, which has a 15-year

tenure and a 68.5 % guaranteedoff-take, SPC will sell all its powerto TNEB. Financial closure of theproject took place on 16 December1999 between SPC and theIndustrial Development Bank ofIndia as the lead institution.

The whole EPC project was splitinto two supply contracts and oneservices contract. The offshoresupply included engines and


Inside view

immediate auxiliaries, as well asprefabricated units for the powerhouse and the unloading and fueltreatment houses. The local onshoresupply included material forannexed buildings, stacks, tanks,pipe bridges, cable ladders andsupports, etc.

Under the local services contractpeople were hired from Finland toguide the installation and alsocomplete the performance tests. Thecontractual time for commissioningand handing over the full plant wasinitially 16 months and 15 days. Thiswas subsequently scaled down bymutual consent to 15 months and20 days.

Difficult terrainThe rugged terrain of the regionposed a major challenge from theoutset of the project. Proper siteroads and drains had to be in placeto ensure smooth transport of theequipment and materials on to theirfinal locations at the site. The drainsset up proved a great advantageduring the heavy monsoons sincethey prevented water logging at thesite that would have hampered theconstruction schedule.

The hard, uneven and rocky soilhad to be levelled by blastingbefore the foundations for thepower plant, the auxiliary units andthe offices and residences could belaid. The two high stacks, 90 metres

and 110 metres, were erectedcolumn by column in heavy windsand unexpected showers.

The 110 kV switchyard, thelargest so far built by Wartsila India,was executed smoothly, withprecision and ahead of schedule.Also for the first time massive rawwater tanks were constructed forthis project.

Demanding transport logisticsBringing the seven engines to thesite was challenging in terms ofspeed, logistics and also obtainingapprovals from the localgovernments. The first shipment ofengines from Finland arrived inChennai in June 2000. Each engine

had to be moved from the port tothe site, a distance of 281 km, in aconvoy of trailers each fitted withsixteen axles. En route, the convoyhad to traverse four railwaycrossings with overheadhigh-tension cables and two bridgeswith a span of 18 metres each. Thetransport from port to site requiredapproximately 20 days, despite therelatively short distance.

The first engine reached the sitein July 2000 and the seventh enginein November 2000. All had beenrolled onto the completedfoundations by November 2000.The first three engines weresynchronized with the grid inDecember 2000 and the remainingfour engines in January 2001.

The performance test for the totalplant was started on 13 February2001, two months and 12 daysahead of the original schedule forcompletion of the performancetrials. A plant load factor of nearly100 % was achieved during theseven-day performance test.

Success through planning,teamwork and communicationSeveral factors contributed to thesuccess of this demanding project.

Meticulous Planning. As thesaying goes, if you need to fell a bigtree, first spend some timesharpening the axe. This wasfollowed in practice with the projectteams in Finland and India planningall activities in detail in advance.One example was to import thestandard power house structure,walls and roof as this proved theonly way to meet the time scheduleand to ensure that the equipmentwas protected against the heavyrains upon arrival. A clear actionplan with milestones was drawn upand monitored at every stage toavoid slip-ups.

Teamwork. The project involvedseveral divisions and departmentswithin the company as well asexternal consultants andsubcontractors. It was very importantthat everyone involved shared thesame mission to complete the projecton time and to co-operateunreservedly. One of the maintargets with frequent internalmeetings and repeated discussionsregarding contract, supply and


design interfaces was to buildconfidence and trust. Every personparticipating in the project acceptedthe challenge and aimed tocomplete their part before thestipulated schedules. If we need tocite a model project to demonstratethe power of teamwork, theSamalpatti Power Project is an apt

example.Involving the Customer. In

addition to frequent communicationby phone and email, regularcoordination meetings betweenWärtsilä and SPC were held toofficially report progress and resolveissues that arose during theexecution of the project. Suchconstant interaction, in an open andtransparent manner, fostered trust,

promoted goodwill and ensuredthat the project did not falter at anystage. In this size of project goodtechnical solutions are important butthe major cornerstones for building

trust are the people involved andcommunication.

Wärtsilä has completed a numberof decentralized power projects inIndia. The two major IPPs,Samalpatti Power Project and therapidly growing Balaji Power Project(105 MW) at Samayanallur, willgenerate the much needed powerthat will help the industrial growthof Tamilnadu. They also serve toreaffirm Wartsila’s long-termcommitment to powering India’sfuture. �

A look at lifecycleeffectivenessIn today’s constantly changingenvironment, where technicaldevelopment is fast andenvironmental concerns are ofever-increasing importance,Wärtsilä is committed to keepingits customers’ investmentsproductive and profitablethroughout the equipmentlifecycle. Lifecycle effectiveness isthe term that describes this policy.

Lifecycle effectiveness is the overallmeasure of operational success. Itincorporates several goals such aslowest lifecycle cost, highestpossible efficiency and the ability tomeet environmental targets. Broadlyspeaking, the concept of lifecycleeffectiveness comprises two keycategories of measurements: theperformance of the equipment andthe personnel operating it, and thefactors that make up theequipment's operational availability.This division is illustratedschematically below.

When a system is new, thedesigned equipment performance isof course at its highest. Equipmentperformance and personnelperformance then constitute theperformance potential of ‘man &machine’.

Operational availability is thepercentage of time that a systemperforms, or is ready to perform,satisfactorily in an operatingenvironment (expressed, forexample, as uptime/uptime +downtime). Uptime and downtimeare affected by three factors:reliability, maintainability andsupportability. There are variousways of looking at availability, e.g.the availability rate based onMWh/year.

Costs are involved in all factorsthat build up lifecycle effectiveness.

Apart from the initial investment,costs include production costs (e.g.fuel, lubricating oil, maintenance,personnel) and the cost ofdowntime – production losses.Market conditions are another factoraffecting the lifecycle effectiveness.

A system that meets theperformance demands andoperational availability targets at thelowest possible cost also has highlifecycle effectiveness.

Comprehensive serviceportfolio for all needsWärtsilä’s proactive approach aimsto ensure that its power plantinstallations worldwide achieve thehighest possible lifecycleeffectiveness. To do this, Wärtsiläprovides operation andmaintenance, technical support,



new technical solutions, audits andinvestigations, and original partsand equipment, either on a dailybasis or as defined by a serviceagreement. The Wärtsilä approachcovers:

• Operation & maintenance support

• Service agreements

• Field and workshop services

• OEM parts

• Technical support

• Technical information & softwaresolutions

• Training.In addition to these services,Wärtsilä employs two specializedfunctions that further contribute tohigh lifecycle effectiveness ofinstallations. One is the ServiceProjects group which handles PlantModernization & Automation. Thisgroup specializes in bringing older

plants up to today’s technicalstandards, covering everything frominitial audit to electrical, mechanicaland automation modernization. Theother is the Operations &Maintenance group, whichspecializes in operating andmaintaining power plants, from thesmallest plants to the largest.

Plant modernization and automationWärtsilä supplies thousands ofmegawatts in power and marineplants every year as well as turnkeymodernization solutions for existingpower facilities and marineinstallations. Since the relativelifecycle effectiveness changes overtime, owing for example to newtechnological developments and theintroduction of more efficienttechnology solutions, a power plantinstallation may need several‘re-vitalizing’ packages to performoptimally throughout its longlifetime.

A particular interesting area,which may not be the first thatcomes to mind when thinking ofmodernization and automation, isthe plant’s electrical system. Therange of Wärtsilä’s modernizationsolutions for electrical systemscovers all aspects of power plantinstallations. The goal is to:

• Avoid production losses

• Maintain high availability,reliability and safety throughoutthe plant

• Maintain protectionselectivity/co-ordination

• Ensure reliable and correctrevenue metering.

Electrical maintenance &automation modernization consistsof standard packages, brieflydescribed below. Upgrading of thevarious systems is based on provensolutions using standard Wärtsilämodules and system componentsdesigned to meet client needs anddemands.

Power system analysisAs is well known, a disturbance-freenetwork or grid is absolutelyessential for maintaining smoothand trouble-free power production.Therefore, a regular power systemanalysis is becoming an increasinglyimportant tool in optimizing theperformance and efficiency of thepower plant.

The plant measurement systemsshould preferably employ thenewest and most efficienttechnology available in order tokeep up with today’s requirementsand tomorrow’s challenges inmonitoring and data collection.Environmental aspects are anotherimportant consideration, especially

the need to obtain accurateinformation on vital energyproduction parameters to keep theplant within environmental limits.

Electrical service packageThis package helps to safeguard theplant against interruptions in powerdistribution. The package containscomplete engine function tests withrunning sequences including safetysystems and controls. All sensors,transducers and meters arecalibrated.

Automation modernizationpackageThis package brings an olderinstallation up to the latest technicalstandards. In many cases this meansadopting digital in place ofanalogue systems.

Remote connections with dataacquisition systems can be alsoinstalled. Wärtsilä offers anunsurpassed range of specializedsystems covering data acquisition,fault analysis, planned maintenanceand technical information.

Complete updating andmodernization can be done eitherfor part of the power plant or forthe whole facility, including themechanical, electrical andautomation systems.


Wärtsilä Operations & MaintenanceAs a large engine plant supplier,Wärtsilä also maintains an internalpower plant Operations &Maintenance group. This group notonly incorporates the know-how ofthe power plant designer andsupplier, but also the experience ofprofessional operators and themaintenance knowledge of theglobal Wärtsilä Service network.

The Operations & Maintenancegroup integrates various parts of theWärtsilä organization: Power Plants,Power Development and FinancialServices, Technology, Service, etc.Hence, the customer gets acomplete package without looseends. The group offers the addedvalue of risk mitigation and assetmanagement, thus maximizing plantlifetime and performance.

In cases where power plantoperation is not the owner’s corebusiness, customers increasingly seethe logic of making an Operation &Maintenance agreement, and theimpact that this has on the powerplant’s lifecycle effectiveness.

Operations & Maintenanceagreements cover mobilization andfull operational responsibility with

performance guarantees of thepower plant and include:

• Project O&M mobilization

• Maintenance planning

• Plant performance and efficiencymonitoring

• Integrated Logistic Support (ILS)and inventory management

• Production and budgeting

• Capital improvement review

• Human resource administration.Every O&M agreement involves twophases: mobilization andoperations. Mobilization, as thename implies, is about hiring andtraining personnel, implementingmaintenance management andreporting software, and puttingadministrative and operationpolicies and routines in place. Theoperations phase is the fulloperation and maintenance of theplant. It covers such areas asmonitoring, trending and reportingof operational performance,maintenance, inventory control, andco-ordination of regular trainingprograms.

The Wärtsilä Operations &Maintenance group currentlyoperates over 70 plants, with a totaloutput of some 1,400 MW. The

O&M group has a proven trackrecord in successful operation ofvarious types of plants, achievingand maintaining very high plantavailability and production figures.Availability figures, for example,often average 95 %. The O&Mgroup’s aim is to reach alleconomic, operational and alsoenvironmental targets such asemissions levels.

The Khulna 110 MWPower CommodoreA typical O&M reference is theKhulna Power Operators Ltd’spower plant in the city of Khulna,Bangladesh. The 110 MW plantconsists of nineteen Wärtsilä18V32LN HFO engines mounted ontwo barges. The contractual capacityis 110 MW.

The power plant is owned byKhulna Power Company Ltd.(KPCL) with major shareholdersincluding Coastal/Elpaso Energy US(74 %). However, responsibility forthe plant’s operation andmaintenance lies with KhulnaPower Operators Ltd (KPOL), asubsidiary of Wärtsilä and formallyowned by Wärtsilä Operations &Maintenance Ltd Oy.

The O&M contract with KPCLstretches for 15 years sincecommercial operation started inOctober 1998. The power barges inKhulna have, at the time of writing,produced some 1,409,000 MWh ofenergy to the Bangladesh nationalgrid. �

Power Commodore to the CaribbeanOne of the world’s largest floating power barges will bedelivered to the Dominican Republic this year to helpmeet an urgent demand for electricity.

The floating Power Commodore, supplied byWärtsilä, will produce 150 MWe of electricity to thenational grid. Prime movers will be nine Wärtsilä 46engines running on heavy fuel oil.

Local utility Empresa Generadora de ElectricidadHaina S.A. has placed the order for the power barge aspart of its commitment to expand capacity in thecountry. Wärtsilä has an EPC contract to supply thePower Commodore and ensure successfulinterconnection with the grid. Apart from being one ofthe world’s largest, it will also be one of the mostefficient and environmentally advanced power bargesever built.

The power barge will be constructed at JurongShipyard in Singapore. It will then be transported by

semi-submersible vessel to its operation location, justoutside San Pedro de Macoris in the DominicanRepublic.

The project is to be completed in November 2001. �

Meeting urgent power needs in Sri LankaTraditionally, Sri Lanka has depended mostly onhydropower for its energy needs. In the last few yearsrainfall has been far lower than normal. Consequently,water levels in their reservoirs are critically low,resulting in a significant shortage of generated power,especially in peak seasons such as the summer months.The problem is made worse by a simultaneous increasein general consumption and demand. Sri Lanka isfinding it difficult to keep up with the country’s energyneeds and is now turning to otherforms of power generation to meetits ever-increasing demands.

As a result Wärtsilä has beenawarded two new contracts tosupply two 24.4 MW Power Masterplants to ACE Power/Matara andACE Power/Anuradhapura, SriLanka. Both contracts wereawarded in the face of toughinternational competition.

The main owners of the newIPP power plants are AitkenSpence & CDC with the plannedoff-taker for these plants to be theCeylon Electricity Board (CEB).

The projects were planned together with WärtsiläDevelopment and Financial Services and will takeeleven months to construct.

In addition to the individual contracts for each site,which are to be completed during spring 2002, each

project also includes a five-year O&Magreement with a five-year option.

Power will be supplied to the 132 kVnational grid via a CEB substation. The33 kV overhead lines, which will bebuilt by Wartsila, are 1.6 km forAnuradhapura and 4.0 km for Matara.

The two power plants are based onWärtsilä’s successful Power Masterdesign, which is ideal for Sri Lanka’sclimatic conditions. The plants willprovide higher power efficiency andlong-term reliability of supply. �

Wah Chang to self-generate heat and powerWah Chang, a division of Allegheny TechnologiesIncorporated, manufactures special metals andchemicals used in energy production, chemical andmineral processing, the aerospace and medicalindustries, research and consumer products. WahChang materials include hafnium, niobium, titanium,vanadium, zirconium, and silicon tetrachloride, andzirconium and hafnium chemicals.

Wah Chang has signed a contract with Wärtsilä for afive-unit Pure Energy combined heat and power (CHP)plant to provide lower cost power than is availablefrom the local utility. The ultimate purpose of thesystem is to lower the manufacturing company’sproduction costs.The low-emission steam and hot water CHP plant willbe installed at the company’s site in Albany, Oregon,USA in July 2001. Designed and manufactured byWärtsilä, it consists of five Wärtsilä 220SG gensets witha plant electrical output of 14 MW and a thermal outputof 16,000 lbs/hour of steam. Wärtsilä is also providingequipment engineering support and installation servicesfor the system.

Wah Chang selected Wärtsilä for the quick delivery time(six months from order to operation), and for thefavourable emissions and efficiency, according to LarryHagel, Wah Chang engineering manager. The systemwill also provide increased operational flexibility whilereducing energy costs, he said. �

Repeat orders to the PhilippinesBusiness and industrial companies in thePhilippines, especially power intensivecompanies like semiconductor and electronicsmanufacturers, are largely dependent onpower generators, distributors and also thegovernment. Increasing power rates,fluctuating voltage and frequency,unavailability, and inconsistent energy policiesare commonplace in the country, affecting thebusiness results.

Wärtsilä recently secured a contractto supply additional equipment toLindeteves-Jacoberg Limited, aSingaporean Independent PowerProducer (IPP) responsible forproviding the powerrequirements of two Philipssemiconductor manufacturing facilities, PhilipsCabuyao and Philips Calaba in Laguna,Philippines. These production facilitiesare already supplied by Wärtsilä 5.2 MWand 6.15 MW heavy fuel oil power

plants. The new equipment will provide additionaloutput of 5.2 MW at each factory, giving them total

independence from the national grid.“In order to stay in business and be

competitive in an increasingly globalmarket, we need to have quality products at lowproduction costs. One way to achieve this is to

have sufficient cheap and clean power.In other words, we must have controlover all cost components of the productsuch as raw materials, labour andpower,” commented the Utilities Director

of Philips Semicon.The project is expected to be

completed during the third quarter of2001. �
