Economies of TRACTION DIESEL VS ELECTRIC

• How Competitive are the Diesels ?

• Is there a need for further Electrification in Indian Railways ?

Page 2: Economies of T RACTION  D IESEL  V S  E LECTRIC

Railway Electrification is justified on various Grounds

Modernization Energy Efficiency Depleting Oil Reserves Savings in Foreign Exchange Marginally Capital intensive, but much cheaper

operationally More Economical Enables higher speeds and improved throughput Higher hauling capability Eco-friendly

How true is the above ?

Electric Traction - 1881

After many decades of satisfactory performance, the steam engines were to give way to more modern locomotives. The year 1881 saw the birth of the first electric Railway run by a German Engineer Werner Van Siemens using both the rails to carry the current. Finding this a little too dangerous, Siemens soon adopted the overhead electric wires. Electric locomotives today raun on Rail roads in many countries.

Page 4: Economies of T RACTION  D IESEL  V S  E LECTRIC

Diesel Traction - 1912

The diesel engine was invented in the year 1893, by a young German Engineer, called Rudolf Diesel. But it was only nineteen years later, that the first Diesel locomotive came into existence.

Since then, diesel traction has grown from strength to strength. Over 89,000 Diesel locomotives have been built in the world so far, the General Motors, USA alone contributing to as many as 56,000 Locomotives.

Page 5: Economies of T RACTION  D IESEL  V S  E LECTRIC

Superior Technology -Diesel or Electric ?

Diesel Traction is thus a far more recent technology, as compared to Electric traction. One reason why there are more diesels in the world than electric locos and why more and more are produced year after year.

Railways in Europe and some other advanced countries had started Electrification many years before the modern Diesels came on the scene.

In fact, Railways in modern economies like US, Australia, etc. are de-electrifying including Suburban services.

Page 6: Economies of T RACTION  D IESEL  V S  E LECTRIC

Superior Technology -Diesel or Electric ? - (ii)

Diesel locomotive is in fact an Electric Locomotive carrying its own powerhouse. Today’s modern Diesel locomotives with 6 KMs of Electrical wiring is much more Electric than an Electric locomotive with 4 KMs of wire.

Electric locomotive provides an easy means of drawing larger units of power from the OHE for the same axle load.

Development of Technology for Low weight energy efficient engine and its controls delayed the advent of modern diesel locomotives.

Page 7: Economies of T RACTION  D IESEL  V S  E LECTRIC

Superior Technology -Diesel or Electric ? - (iii)

Today, technological development in both tractions has levelled of.

And for the same weight, Diesel traction has 10% or higher load hauling capability.

It is conceded that technology of high speed Passenger operation beyond 220 Kmph has advanced on Electric traction, but this is perhaps quite irrelevant to us today.

Diesel locos with Electric transmission have all the benefits of modern technology such as AC-AC transmission.

Electrification on IRIt is often said that

Electrification on IR is hardly 24.5% of total network.

The truth is Total Network includes BG, MG as well as NG and is

62759 KMs. Actual BG Route Kilometers are 44383 BG Running Track KMs are 62441 Electrified Running Track KMs - 27946 which is 44.8% of BG Running Track KMs.

Electrification on IR (ii) Railway Electrification on the IR was taken up in a big

way in the late 70s, as a knee jerk reaction to the 1974 oil crisis.

Central Organisation for Railway Electrification (CORE) was created to speedily electrify the high density routes; this task has already been completed in the early 90s. While talking of 1980 Secretary’s report, we have blanked off Gujral Committee Recommendations and the falling crude prices in later years.

It is felt that Electrification of Low density non-viable and uneconomic routes continues unabated, perhaps to sustain the organisation.

Time has perhaps come, to pause and examine if the need for further electrification still persists.

Page 12: Economies of T RACTION  D IESEL  V S  E LECTRIC

Energy Efficiency Sometimes Electric traction is perceived as more

energy efficient, by wrongly computing the efficiency from the Overhead wire, in stead of from the Primary Source of Energy, viz., Coal / Oil (used in producing electricity in power houses)

The energy efficiency of Traction should however be calculated right from the Primary source of Power, taking into account, losses occurring at every stage.

(For example, in production of Electricity in Power houses and Transmission and Distribution)

Availability of Oil (Reserves)

Ever since Col. Blake discovered oil in 1857, this is the usual pessimistic refrain that we hear.

Arthur Anderson/Cambridge Energy Research Associates reports:In 1970, the reserves were estimated to last 33.78 yearsIn 1980, the estimate was 33 years despite increase in

consumption by 30%In 1999, oil reserves were estimate to last 43 years

despite increase in consumption by 43%

Will there be any Oil after 30 years ? ? ?

Availability of Oil

The Government is investing Rs.54 400 Crores in connecting the Golden Quadrilateral and diagonals by Super Highways.

Almost every Automobile / Light Motor Vehicle Manufacturer continues to expand their production capacities.

Fuel CellsA simple device uses Hydrogen from fuel

combines with Oxygen and produces electricity.No noise, no smoke and no moving partsAs per International Railway Journal of March

2000, Fuel Cell Trains shall be a reality by 2008.A breakthrough has already been achieved by

BHEL, HydrabadAll Overhead wires will then become redundant !!!Diesel locos can be easily converted by replacing

engine with fuel cell.

The Indian Scene Annual Growth rate -8% compared to world average of

2% Oil pool deficit & subsidies Rs.16,000 Crores, Rs.18,440

Crores (1996-97) Current per capital usage of petroleum is abysmally low

(0.1 ton / year) against 4.0 in Germany or 1.5 tons in Malaysia

Even Malaysia’s figure would be beyond our paying capacity

Our domestic production would meet only 33% of demand at the end of 10th plan and only 27% by 2010-11

Investment in Biofuels make strong Economic sense.

Page 27: Economies of T RACTION  D IESEL  V S  E LECTRIC

Jatropha may be the Answer

According to the Economic Survey (1995-96), Govt. of India, of the cultivable land area about 100-150 million hectares are classified as waste or degraded land

Jatropha (Jatropha curcas, Ratanjyot, wild castor) thrives on any type of soil Needs minimal inputs or management Has no insect, pests & not browsed by cattle or sheep Can survive long periods of drought Propagation is easy Yield from the 3rd year onwards and continues for 25-30

years 25% oil from seeds by expelling 30% by solvent extraction The meal after extraction an excellent organic manure (38%

protein, N:P:K ration 2.7:1.2:1)

Electrify the Railways and Dieselise the Industry ??

In a country where 14.7% villages are yet to be electrified, can we afford to electrify Railways ?

The Energy Policy should ideally aim at replacing inefficient use of Fuel

Electrification replaces a highly efficient Turbo charged Railway Diesel locomotive with small sized high inefficient gen-sets resulting in higher consumption of HSD and pollution.

Optimum Utilisation of Energy - Petroleum

There is a lot of reluctance in the States for establishing any new coal-based Power Plants in view of the serious limitations like poor quality of coal with high ash and sulphur content, pollution of ash and dust, high cost of developing new coal fields, extreme shortage of water, etc,.

Most of the Power houses set up in the country in the last five years and those in the pipe line are based on Petroleum products such as LNG, Diesel, Naptha, etc.

Page 38: Economies of T RACTION  D IESEL  V S  E LECTRIC

Does Electrification save Foreign Exchange ?

Electrification ends up draining the Foreign exchange, instead of saving it.

The classic case is Ernakulam - Trivandrum Electrification at Minus 29% rate of return, tapping Power from a Diesel Power station of Nallalam.

Capital investment in Power plants is mostly by way of imported equipment.

Page 39: Economies of T RACTION  D IESEL  V S  E LECTRIC

To Sum up,It is quite obvious that

Electrification of Railways

is leading to:Dieselisation of the Industry,

Agriculture and Domestic Sector

Increased Fossil Fuel Consumption

and not Reduction

Higher Outflow of Foreign Exchange

and not savings for the Nation

Breakeven was given a Go By since no sections on IR in 1996 qualified for Electrification on 49 GMT basis and the CORE was facing a closure.

If ROR should only be the criterion, can we de-electrify the low density routes already electrified ?

If Oil prices come down, as it did from $36 in 1979 to $9 in 1998, can we attempt de-electrification of the entire country based on ROR ?

Recommendations of Gujral Committee - 1990

For the period 1990-2005, Electrification of 2510 KMs recommended.

Electrification recommended @ 214 Kms per year Sections specifically recommended for Not

Electrifying already electrified. Actual Electrification done between 1990 and

2000 has been 5000 KMs which is double of what was recommended.

Rate of Electrification is 2.33 times of what was recommended.

Line Haul Costs

In any case,

the Average Line Haul Cost

derived from the High Density Electrified Routes cannot obviously

be Extrapolated to justify the Electrification of Low Density

Routes.

Page 56: Economies of T RACTION  D IESEL  V S  E LECTRIC

Procedure for sanction of Electrification Projects

Each Electrification Project will be justified on ROR which should exceed 14% with the DCF Method.

In certain specific cases, Electrification will be justified on considerations of Operational flexibility

Electrification of a single line section (Main Line) will normally not be considered.

The ONLY Recommendation followed is

to Do Away with Breakeven,

due to obvious reasons.

Railways have made no provision for energy meters in locomotives either to monitor the electric energy consumption or to work out the electricity consumed for electric traction of different classes of traffic.

The apportionment of electricity consumed between goods and passenger services is being done on an estimated standard specific energy consumption (SEC) for passenger services.

The SEC adopted was obviously erroneous. Sometimes, the adopted SEC for passenger traffic resulted in negative consumption for goods traffic.

The figures, therefore, have no realistic basis.

Page 61: Economies of T RACTION  D IESEL  V S  E LECTRIC

Electrification of the main routes picked up momentum in 1970s. By March 1999, 14,050 route kilometres were electrified at the cost of Rs.4,008.55 crores. It is imperative that a review is undertaken now for choice of traction with reference to the operational results of the electrification already done. Review by Audit of 2 electrified sections and a project completion report prepared by the World Bank in 1994 tend to indicate that the projected returns were significantly overstated and could not be achieved. Besides, the expected economy in cost of operation has not fructified having regard to the trend of international oil prices vis-à-vis the sharp rise in domestic electricity costs. Further in Indian conditions, uninterrupted electricity supply to Railways inevitably affects industry adversely. (Para 7)

Study by LRDSS Conclusions

HP to Load Ratio of 1.5 - Most beneficial & Cost effective. This, of course, pertains to sections near saturation. On Passenger dominant sections, HP to Load Ratio >2 for Diesel also. Further overpowering not recommended. - Benefit insignificant.

On Single Line sections, gain under Electric traction is low. (Tract & Other reasons limit the speed improvement). HP to train load ratio is not a traction specific issue.

Positive impact of Electric traction on Freight dominant double line sections where HP to trailing Load ratio is low. - 12 - 16% higher line capacity

This recommendation of course is not traction specific but only HP specific.

Environment Issues

Contrary to popular perception, Electric traction is more polluting than Diesel traction.

Power for Electric Loco comes fromeither Diesel based Power station with

same level of pollution as Diesel locoOr from Coal based Thermal station whose

“Green House” gases emission is 26% more than Diesel loco (UNDP Study)

Page 71: Economies of T RACTION  D IESEL  V S  E LECTRIC

Electric Loco- Environment friendly - Is that really so ??

One Electric Loco of 5000 HP requires 4.2 MW of Power.

One MW of Power requires 10 Tonnes of Coal per day

And at 40% Ash content, generates 4 Tonnes of Coal Ash per day.

Source: Central Electricity Authority Annual Report 1998-99

= 16 Tonnes of coal Ash per day

Is Electricity overpriced ?

Railway Traction needs immune power, with no cuts, warranting duplication of Transmission and Distribution systems, which obviously comes at a Premium.

Unlike HSD, Electricity is subsidised by waiving off Sales Tax and Excise, though it is an Economic Good

manufactured and sold.

Conclusions Electric Vs Diesel debate is not an issue of Departmental

dominance but Economic survival. Electrification of High Density Traffic Route (49.72 GMT

and above) is not being questioned. There is no pressing need for electrifying remaining

sections when Railways are facing Financial Disaster. A complete moratorium on Electrification should be place,

as an immediate measure. CORE should be wound up. Work of ongoing projects should be executed only by the

concerned Railway as is the case with projects of BG conversion, doubling of lines and other Engg. / S&T / Elect. Works, which also overlap on Multiple Railways.
