The Power of Team
Getting the hang of team denitely takes a while. When
I entered the industry, I didnt like working on teams.
I couldnt work at my own pace or on my own sched-
ule, and it seemed like every team had at least one slacker who
dragged down the team.
Team is a way of life in the working world. Yes, team still has
its frustrations, but working solo has lost a lot of its appeal as I
have come to realize that, on the main, collaborating is more
fun and brings superior results and increased buy-in.Here is an example of an initiative that could only be ac-
complished through the power of team. I was on a team at
Georgia Power assigned to develop a residential and small
commercial power-quality program. Over the course of a year,
I discovered rst-hand that Georgia Power had incredible tal-
ent spread throughout the company. We had members from
power quality, operations, customer care, customer research
protection and control, the meter lab and the test lab.
Every person on that team would prove to be essential as we
worked together to come up with a roadmap to offer a higher
level of power quality to our customers. The proposal we made
to management was much stronger than any effort that couldhave arisen from any one department. And a series of focus
groups helped us understand what our customers really want-
ed, including how they would like to be approached. The nal
proposal included a residential offering that provided indi-
vidual surge-suppression devices in the home and a meter ex-
tender that contained lightning protection. Although I left the
company before the nal program was rolled out, I checked
back to nd out that the program was quite well received.
Not All Teams Are Supported EquallySometimes utility leadership misuses the concept of team.
And without enlightened leadership, collaborative efforts of-
ten fall short. Ive seen utility executives hijack the concept of
team and use it to coerce people into going along by stating,
If you arent willing to get with the team, you will be taken
off the team. More than one engineer has been given the
package for non-compliance.
Even the best utilities occasionally place individuals in ex-
ecutive positions who are a poor t and, ultimately, hurt the
health of the company. Working with teams under one of the
following executive types is usually an exercise in futility. See
if your department has had to survive one of these executives.
The Rotating VPThis is one of those manufactured executives who has been
preordained for greatness, but before he can put on his des- Editorial Director
tined crown, he is dipped into two-year stints across a wide
spectrum of organizations. He doesnt really know your busi-
ness and, therefore, will have a hard time directing the team.
Also, he will likely be moved to his next rotation before the
team is scheduled to deliver on its assigned task.
The Torch VPThis VP has been brought in to restructure the department
and get rid of dead wood so the company will be leaner andmore productive. His role is to tear apart, not to build. Team is
a foreign concept as long as this person is in place.
The Ex-Military VPThis VP is typically brought in to add a level of discipline to
the department. Of course, with this background, he is quite
comfortable using authority and values process teams. This
VP is often a bust in T&D. Too often, he has a serious decit in
the area of people skills. And there are so many critical links
between power delivery and the various stakeholders that re-
quire an empowered, not a cowered, workforce.
The Glad-Hand VP
This VP is brought in to mend fences after one of the more
hard-nosed VPs has been running the organization. He is not
likely to hold process teams accountable, so initiatives tend
to drag out. Also, although teams might be crafted, they will
usually tackle cream-puff assignments like handling coffee or
coming up with morale-building activities.
The Enabling VPNow this is my favorite type of executive. This VP realizes
he cannot have a signicant impact unless he hires and sup-
ports people as smart or smarter than himself. He wants to
provide the people in his organization with the tools to get
the job done, to encourage his team to work together, to reach
common stretch goals and to celebrate successes.
Though we are all familiar with the concept of team, we
dont always experience true alignment. Only when manage-
ment believes in an empowered workforce and works to un-
leash the talent that exists in our organizations will we reach
our true potential. Most of us came into power delivery to
serve, and we are more than willing to work together to make
a bigger difference.

BUSINESSDevelopmentsNational Grid EntersNext Phase of ItronSmart Grid SolutionInstallation
National Grid has entered the next
phase of its smart grid project, com-
pleting installation of Itrons OpenWaysmart grid platform for its Smart Energy
Solutions Program in Worcester, Mas-
sachusetts, U.S. The platform, which
features an advanced IPv6 network pow-
ered by Cisco, enables National Grid to
increase electric service reliability, im-
prove response to power outages and
empower customers to save energy. Na-
tional Grid uses Itron Services to man-
age and maintain the network.
In this new phase of the smart gridproject, National Grid is using Itrons
smart grid solution to enable consumer
engagement programs that give the util-
itys customers better insights into their
energy use and costs. Later this year,
National Grid will also offer customers
time-based pricing plans to help custom-
ers achieve even more energy savings.

Google Invests in Clean Energy FutureOn Earth Day, Google announced its largest renewable energy purchase yet: an
agreement with its Iowa utility partners to supply Google data center facilities in
Iowa with up to 407 MW of wind energy. Now Google is taking another step towarda clean energy future with its next major investment.
Together with SunPower Corp., Google is creating a new $250 million fund ($100
million from Google and $150 million from SunPower) to help nance the purchase
of residential rooftop solar systems making it easier for households across the
U.S. to go solar. Using the fund, Google will buy the solar panels and lease them to
homeowners at a cost thats typically lower than their normal electricity bill. Par-
ticipating in the program allows customers to help the environment and save money.
SunPower delivers solar to residential, utility and commercial customers and
also manufacturers its own solar cells and panels. The company is known for having
high-quality, high-reliability panels that can generate up to 50% more power per
unit area, with guaranteed performance and lower degradation over time. Thus,fewer solar panels are needed to get the same amount of energy. SunPower makes
the panels and manages the installation, so the process is seamless.
This is Googles 16threnewable energy investment and its third residential roof-
top solar investment. Overall, the company has invested more than $1 billion in
16 renewable energy projects around the world.

FERC Directs NERC
to Develop PhysicalSecurity StandardsThe Federal Energy Regulatory
Commission (FERC) directed North
American Electric Reliability Corp.
(NERC) to develop reliability standards
requiring owners and operators of
the bulk-power system to address risks
caused by physical security threats and
vulnerabilities.
The reliability standards require
owners and operators of the bulk-powersystem to take at least three steps to pro-
tect physical security:
Perform a risk assessment of their
system to identify facilities that, if ren-
dered inoperable or damaged, could
have a critical impact on the operation
of the interconnection through instabil-
ity, uncontrolled separation or cascad-
ing failures of the bulk-power system
Evaluate potential threats and vul-
nerabilities to those facilities
Develop and implement a security
plan to address potential threats and
vulnerabilities.
Recognizing that critical facilities
identied pursuant to the required reli-
ability standards could contain sensitive
or condential information that, if pub-
licized, could jeopardize the operation
of the grid, FERC directed NERC to
include a procedure that ensures con-
dential treatment of sensitive or con-
dential information, but still allowsfor the appropriate oversight to ensure
compliance.

800-kV HVDC Converter TransformerPasses Factory Acceptance Test in China
NV Energy Increases Customer Engagement Using BuildingIQ
On March 1, 2014, Alstoms rst 800-kV HVDC converter transformer passedfactory acceptance tests in Shandong, China. This converter transformer will en-
able the State Grid Corporation of China (SGCC) to power part of the Jinping to
Sunan 2,090-km (1,299-mile)-long UHVDC power link. The link will transport
clean hydropower from generating stations in central western China across to the
industrialized coastal area in eastern China.
This leading-edge technology is the result of a cooperative project between
Alstom Grid and Shandong Power Equipment Co. Ltd. (SPECO), a subsidiary
of SGCC. The trans-
former was designed
by Alstom Grids
HDVC experts basedin Stafford, U.K.,
and engineers work-
ing out of Alstoms
Wuhan factory in
eastern central Chi-
na. Alstom supplied
all the critical mate-
rials and supervised
the production at
SPECO. Alstom also
provided the neces-
sary training from itsexperts based in both the U.K. and China. Alstom also undertook critical parts of
the production process and provided bushings from its factory in Italy.

NV Energy has implemented a new program using Build-
ingIQs integrated energy-efciency and automated demand
response (autoDR) solution and has enrolled some of its larg-
est customers in Las Vegas, Nevada, U.S., including casinos,
government and commercial buildings.
BuildingIQs cloud-based software, which incorporates
Predictive Energy Optimization, receives electronic signals
from NV Energy and automatically manages DR events for
customers without disruption to comfort or operations.
NV Energy has reduced peak HVAC power consumption in
buildings by as much as 20% on DR event days. The program
has signicantly lowered on-going daily HVAC energy use for
customers by 10% to 18% compared to baseline.
The incorporation of BuildingIQ is part of a larger custom-
er engagement program for NV Energy through its mPowered
Optimization program, in which customers receive access to
the software and associated energy savings in return for partic-ipating in DR events. The program, launched in the summer
of 2013, has already boosted energy efciency in its customers
facilities while providing signicant peak load reductions for
the utility. The M Resort Spa Casino, a Forbes Travel Guide
four-star resort and casino in Las Vegas, has deployed Buildin-
gIQ in its ofces, conference space, restaurants and casino ar-
eas, and has realized signicant results in the rst few months
of the program, achieving 12% energy savings in HVAC en-
ergy in September 2013. Energy usage has been optimized
without sacricing the comfort of guests, visitors or staff.
BuildingIQ is a unique player in the smart buildings mar-
ket, using its proprietary software to hunt for and automati-
cally take advantage of untapped energy-efciency gains
in commercial buildings in real time, says Eric Bloom, senior
research analyst at Pike Research, a division of Navigant. The
need for automated, real-time response from commercial
buildings will only grow as utilities face an increasingly dif-
cult challenge of maintaining grid reliability cost-effectively.
With autoDR capability built into its platform, BuildingIQ is
poised for signicant expansion in the utility sector, and itsprogram with NV Energy is a key example of the promise
BuildingIQ holds.

Weather Is Money
ByJohn Baker,Energy Editor
Ever since the 1950s when the wide spread adoption of
residential and commercial air conditioning began to
drive peak system demand, electric utilities have rec-
ognized that good weather forecasts are essential to good
load forecasts. Good load forecasts, in turn, are needed for
efcient dispatch and proper system operation. This con-
nection between efcient, reliable operations and weatherforecasts, important today, will be even more crucial in the
future. So crucial that the monitoring, modeling and predict-
ing of weather conditions will become an integral part of fu-
ture utility operations at all levels. What would drive utilities
to become so heavily involved in the science of weather? The
answer lies partly in the increasing number of electric utility
operations that will be heavily tied to weather in one form or
another.
To begin with, unless future air conditioning will be ac-
complished without electricity, future operational load fore-
casts will still heavily rely upon accurate weather models and
forecasts. Closely related to load forecasts are demand re-sponse (DR) forecasts. If DR is to become a viable utility-scale
resource, then the amount of load reduction expected under
different weather conditions will need to be known with a
high level of certainty. Given that much of the potential for
DR is tied to air conditioning, the need for accurate weather
forecasts surfaces again.
Several DR service providers and aggregators are develop-
ing sophisticated thermodynamic models for individual resi-
dential homes. Why is this important? Keep in mind that DR
is a fancy term for shutting off customers appliances. These
models do a better job of estimating how much curtailment
can be achieved without customers becoming uncomfortable
and abandoning a DR program. In this way, these models pro-
vide greater certainty for DR resource estimation and hold
the promise of helping utilities identify customers who may
benet from various energy-efciency programs. Since these
models are enhanced with local information such as tempera-
ture, solar insolation and wind speed, they will require more
granular weather data.
Storm prediction and grid-damage assessment are draw-
ing growing interest by utilities in new weather applications.
This interest has taken on more urgency as the number of
storms that have caused widespread outages have been track-ing upward over the last several years. Storm predictions have
long been used to pre-position emergency repair crews before
large storms arrive. There is increasing interest in using light-
ning, wind and other storm data to facilitate the identication
of damaged grid components after a storm. Some weather
experts suspect we are moving into a time that will be marked
by increasing weather volatility. This trend, coupled with util-
ity customers ever-rising desire for awless electric service,
would underscore the need for advanced storm-prediction
and damage-assessment capabilities.Renewable generation also requires good weather forecast-
ing. Wind and solar generation are already at considerable lev-
els on parts of the U.S. grid. In those areas, the need to accu-
rately model renewable resources exists today. This need will
become more acute as the percentage of renewable resources
on the grid grows. This is particularly true for distributed so-
lar photovoltaic (PV). The ability to model and predict the
electric production from distributed solar PV is important at
the system level as well as at the distribution level. A distribu-
tion grid with a high level of distributed solar PV dispersed
across its service area is a good example. As cloud formations
move across the example grids service area, they will causethe PV production to rise and fall with the passing clouds.
This will impact the net system load as well as the loading of
individual feeders and substations. As solar PV penetration
levels increase, effective ways of modeling the local weather
impacts on distributed solar PV will be essential for stable grid
operations
With all this potential for increased weather dependency
on the grid, a question arises: If the world is experiencing
some level of climate change, how will such change affect
weather-dependent resources on the grid? In particular, how
will possible climate changes potentially impact expected en-
ergy production from solar and wind resources in the future?
One of my old engineering professors was fond of say-
ing, The solution is intuitively obvious to even the most ca-
sual observer. The answer to this question wont be. However,
what is certain is that if the grid and by direct association our
economy are to be increasingly more reliant upon weather-
dependent resources, then grid operators will need to become
highly procient at monitoring, modeling and predicting
weather conditions at a very granular level.
Editors note: Insights were fueled by discussions with John
Bosse, director of energy services, Earth Networks; Dr. MerwinBrown, co-director of electric grid research, California Institute
for Energy and Environment, University of California; and Don
Leick, senior energy product manager, Schneider Electric.

Two for One
Eriks Surmanis,Power Delivery Consultants (left)
ByJames R. Dukart, Contributing Writer
Eriks Surmanis is an active guy, to say the least. Cur-
rently a senior engineer at Power Delivery Consultants
in Middletown, Connecticut, U.S., Surmanis served as
vice-chair for the 2011 IEEE ESMO show and will chair the
next ESMO. He serves on a board that sends relief supplies
to Haiti, is an avid golfer and hockey player, is married andhas two young sons, 4 and 6. Listening to all that Surmanis is
involved in, youd be forgiven if you thought the name Eriks
referred to more than one Erik.
It doesnt, though. Surmanis is Latvian and explains that all
Latvian males have an s at the end of their name. Thus, he
is Eriks in his e-mail and on his rsum, and when you want
to talk about something he has done for instance, sending a
re truck to Haiti for earthquake relief you say, Eriks helped
make this happen. If you were talking to him, you would say
Erik, but he goes by both in day-to-day life, and even quips
that the Latvian Olympic hockey team nicknamed its coach
Canadian Ted Nolan Teds as an honorary Latvian.In Surmanis case, again, the English-language plurality
of his rst name only hints at the fact that he does a lot for
one man. In addition to his full-time job at an engineering
consultancy, Surmanis is a fundraiser and board member of
Haiti Works!, a Bridgeport, Connecticut, organization that
organizes and sends humanitarian aid to Haiti, which is still
recovering from a massive earthquake in 2010.
Most recently, Surmanis was instrumental in getting a
vintage 1980s Mack re truck sent to Ptionville, a suburb of
the Haitian capital Port au Prince that was particularly hard
hit and still is trying to recover. The truck was donated by a
Connecticut re department, and Surmanis not only helped
source the donation, but he helped put together transport ar-
rangements to Haiti via U.S. Military Aircraft.
First, they need emergency rescue vehicles there, Surma-
nis notes. They use this one mostly for crowd control at large
public gatherings. But you might also ask, Why send an old,
1980s vintage re truck? Its actually an advantage. It is not
as computerized as the re trucks of today, and so it has parts
that anyone in any country can repair and replace.
Surmanis also helps Haiti Works! send food and clothing
aid to Haiti, including thousands of pairs of work boots.
This is critical, Surmanis says. What you see on televisionis the way it is [in Haiti]. Collapsed buildings still leave sharp
metal and concrete edges exposed, and it can be dangerous to
walk around without good protective footwear. Construction
workers, in particular, need work boots to do their jobs.
Back in Connecticut, Surmanis is currently visiting poten-
tial sites and helping put together the program for the next
IEEE ESMO show, which will likely take place in 2016. He
likens ESMO to the Olympics, not in terms of athletic com-
petition but in terms of being a nationwide and, in fact, in-ternational gathering that takes place once every four years,
on average, and features world-class learning opportunities
revolving around electrical line worker safety.
Our real goal is to get new safety and work practices out,
Surmanis explains. Personnel changes all the time, and some
people have never seen a lot of helicopter line work, for in-
stance. The format of ESMO is to have Monday and Wednes-
day indoor conference and educational sessions, with Tuesday
and Thursday full-day outdoor training. You will see new
pulling rigs, new tools, techniques and equipment, even the
work of robotic arms in line repair, Surmanis states. By the
next ESMO, who knows, we might even see some drones yingaround doing line reconnaissance or maintenance. Plus, you
know linemen always love to go for a ride in the newest, tallest
bucket trucks!
Outside the ofce, Surmanis is an avid golfer and hockey
player, and involved father with his two boys, Luke and Mark.
Even then, he manages to combine his passions with good
deeds and education. Last year, Surmanis organized and host-
ed a charity golf tournament for Haiti Works! at the Richter
Park Golf Course in Danbury, Connecticut, and is in charge of
its second iteration again this coming fall. He considers him-
self an avid though still-learning and improving golfer.
Lindas theory is that I only really gravitate toward sports
and recreations that are nearly impossible to master, Surma-
nis notes, without disagreeing with his wifes assessment.
Surmanis plays hockey in a mens league in Hartford, Con-
necticut, but also travels to Canada whenever he can to both
play and watch the sport there. He says he came to hockey rela-
tively late in life as an adult, not youth hockey and hopes
his sons might pick up the sport earlier.
As to his dream round of golf, Surmanis offers up some-
thing of a surprise. This past year, he explains, his oldest son
enrolled in the PGA First Tee program for beginning golfers.
You want to know what golfer Im jealous of, its my six-year-old son! Surmanis jibes. He gets eight weeks of golf for
something like $40, and gets to play every week at the TPC
Highlands in Cromwell. Hes got it pretty good!

Renewable Energy
Often the word unique is overused in todays
evolving society. However, that descriptor iscompletely appropriate to label the 231-mile
(372-km)-long, single-circuit 500-kV One Nevada
transmission line in the United States.
What other line caused construction workers to bundle up
for an early fall mountain snowstorm at the exact time other
workers on the same line had to stay hydrated because of tem-
peratures that climbed to nearly 100F (38C)?
What other line is designed with a special tubular guyed-V
structure to inhibit raptors from perching and attacking pro-
tected desert tortoises in southern Nevada or sage grouse in
northern Nevada?What other transmission line offers a critical solution to
connecting two operating utilities for the rst time and en-
abling Nevada customers to benet from sharing generating
resources?
And, what other line can simultaneously transport elec-
trons from a large wind farm, numerous geothermal plants,
large solar facilities and a small landll energy resource?

The answer to these questions validates that the word
unique does apply, indeed, to the One Nevada TransmissionLine, or ON Line, which began serving homes and businesses
in Nevada on New Years Day 2014.
Renewable EnergyThe diversity of renewable energy in Nevada towers above
most states, and ON Line plays a key role in enabling the en-
ergy to ow to customer load centers. Prior to the completion
of this line, the energy from 20 separate geothermal projects
could only be used in northern Nevada. Energy from eight
of those geothermal projects is specically contracted
through ON Line to NV Energys operating company that
serves the greater Las Vegas, Nevada, area. Energy from therich solar resources in southern and central Nevada now can
ow both directions on the line and nd its way to where it is
needed most.
One groundbreaking project that will use the new trans-
mission line almost exclusively is the 110-MW Crescent Dunes
Solar Energy Project, which is the largest solar power tower
project with energy storage. Thanks to a
molten salt storage system, this project can
provide solar energy long after the sun has
gone down and when air conditioners are
still running full blast to counter midnight
temperatures well above 90F (35C).
The new transmission line also is be-
ing used to move up to 152 MW of wind
power from the Spring Valley Wind Proj-
ect in eastern Nevada to Las Vegas, as well
as a small landll gas-to-energy project
in northern Nevada. Overall, the initial
phase of the line is designed to carry nearly
600 MW of renewable energy.
A Collaborative Effort
NV Energy teamed up with Great BasinTransmission-South, LLC, an afliate of
LS Power, to develop and build ON Line.
Great Basin owns 75% of the line and
NV Energy owns 25%, although NV Energy has rights to 100%
of the lines initial capacity.
NV Energy managed the construction process, which in-
cluded 844 towers, a new 500/345-kV substation located in a
remote part of Nevada, a 20-tower backup microwave commu-
nications network, a short tie-in line with the utilitys existing
345-kV transmission system in northern Nevada, and upgradesto the 500-kV Harry Allen substation north of Las Vegas.
Sturgeon Electric Co. Inc., a MYR Group Inc. subsidiary,
provided construction services for ON Line, including envi-
ronmental protection measures, right-of-way clearing, founda-
tion installation, structure installation, and installation of the
conductor and shield wires.
Wilson Utility Construction Co. provided construction
services for the new Robinson Summit substation west of Ely,
Nevada. Its involvement included environmental protection
measures, grading, foundation installation, structure installa-
tion and installation of electrical equipment.POWER Engineers provided the engineering services for
the transmission line and substation.
Unique Tower DesignThe ON Line project is considered the rst in the indus-
try to use a reverse-tapered, tubular guyed-V structure con-
guration. The structures range in total height from about
110 ft to 160 ft (34 m to 49 m), depending on local terrain,
span issues and elevation changes. The structures are made
from self-weathering steel, which evolves to a rich brown color
that blends well in the desert environment of Nevada.
The new line runs almost exclusively through federal landmanaged by the U.S. Bureau of Land Management, and the
structures offer one of the smallest tower footprints of any
structures previously used.
The guyed-V structures use a reverse-tapered, thin-walled
tubular steel leg, which minimizes the tower weight and foot-
print. It rests on a tapered concrete pedestal foundation that
More than 100 MW of energy collected by the 640-ft-tall power tower atthe Crescent Dunes solar field in Nevada will flow to Las Vegas throughthe new One Nevada Transmission Line later in 2014.
The ON Line towers have a remarkably small environmental footprint that incorporates asmall precast concrete base and four guy wire anchors.

measures about 6 sq ft (0.5 sq m), with a reveal of only about
1 ft (0.3 m), and measures roughly 3 ft by 1.5 ft (0.9 m by 0.5 m).
The legs rest on two steel rocker plates and pins that t into
the bottom of the tower legs.
The only other footprint elements are the four corner
grouted soil and rock anchors, which were drilled to depths
up to 40 ft (12 m). Each anchor was eld-tested to 80,000 lb(36,287 kg) and is the termination for two guy wires, one of
which has a 0.875-inch (22-mm) diameter and the other has a
0.5-inch (13-mm) diameter. More than 3,000 anchors were in-
stalled and only two failed the pull test and needed replacing.
Hoisting into PlaceThe tubular guyed-V tower structures all were assembled
on site and installed with the use of a single crane, forklift and
individual work trucks at the four anchor points. Over time,
the carefully choreographed and practiced crews of about 10
workers were able to install a new V-tower every 50 minutes.That process included time for the large crane to lumber to
the next tower site, set up, extend, lift the structure, set it on
the foundation and hold in place while the tower was plumbed
and the main guy wires were tensioned to about 10,000 lb
(4,536 kg).
Lead lines for the ON Line conductor, overhead and opti-
cal ground wires all were own in by helicopter, which dra-
matically shortened the construction time associated withAt the height of construction, approximately 400 workers worked ondifferent aspects of the ON Line project.

traditional pole climbing or high-lift bucket support. Helicop-
ters were also used to inspect the completed towers and work,
as well as to help install backup microwave towers on remote
mountain peaks in Nevada.
Environmental AttentionAll of the work crews received environmental awareness
training to learn and understand the sensitive environmental
resource issues associated with the projects activities. For ex-
ample, protected desert tortoises presented the most sensitive
issue for the project. Biological monitors surveyed work areasprior to construction activity, safely relocated tortoises from
harms way when necessary and supported all work crews dur-
ing their work to ensure compliance with environmental re-
quirements. Biological monitors also escorted dust-mitigating
water trucks, work crews and equipment moves throughout
the desert tortoise habitat as well as the habitats of other sensi-
tive species of plants and animals.
Additional specialized personnel surveyed and monitored
construction activities for the protection of sensitive plants,
paleontological resources, archaeological resources, migra-
tory birds and greater sage grouse.
Certain protected plant species such as cactus and yucca
plants in planned construction areas or on new access roads
were temporarily moved from harms way and maintained
during the construction phase of the project. After the con-
struction work, the areas were recontoured and decompacted.
Any topsoil removed prior to construction was replaced to
help maintain the native seed bank.
To further support successful revegetation of the tempo-
rary work areas, seeding was done using native plant seed
mixes corresponding to the local vegetation community, and
the cactus and yucca plants that had been removed prior to
construction were replanted. Crews took care to ensure eachplant was replanted as close to its original location and orien-
tation as possible.
Certain restrictions also were imposed on construction ac-
tivities in specic areas because of sensitive seasonal wildlife
activities, such as mule deer wintering grounds, sage grouse
lekking and migratory bird nesting. In accordance with the
Edison Electric Institutes Suggested Practices for Avian Protection
on Power Linesand in coordination with the Bureau of Land
Management, Nevada Department of Wildlife, and U.S. Fish
and Wildlife Service, project structures were designed to avoid
electrocution of eagles and other large raptors. Specic struc-
tures were tted with perch-deterring devices to discourage
ravens and raptors from perching and nesting on structures
within sensitive habitats for sage grouse and desert tortoise.Thanks to the sharp eye of an environmental monitor,
evidence of a 300-million-year-old plant was found near the
ON Line construction activities. The rare-for-Nevada fossil
clearly shows the diamond-shaped bark pattern of a lepido-
dendron tree, which grew to more than 100 ft (31 m) tall.
Wind-Induced Vibration IssueOne of the lessons learned about the new tubular guyed-
V structures is that the tall slender structure was susceptible
to wind-induced vibrations. The solution involved retrotting
the towers with helical strakes from Chicago Metal Rolled
Products. Helical strakes are cost-effective and well-tested de-
vices that alter the ow of wind around the tubular structures
and disrupt vortex shedding.
Thanks to extensive testing and ongoing vibration moni-
Thanks to a design that uses a downward force from pre-tensioned guywires, the ON Line tower structures merely rest on convexed rockerplates held in place by two 6-inch pins that fit into holes on the bottom
of the two tower legs.
In total, more than 1,100 miles of conductor and ground wire leadlines were safely strung with helicopters during the project. Asshown here, one of the most difficult tasks was stringing the center
conductor line with a needle apparatus.

tors at 11 towers, the helical strake solution successfully miti-
gated the wind-vibration problem.
Good To Be ConnectedNV Energy has evolved from two separate operating com-
panies in Nevada Sierra Pacic Power Co., which serves
about 42,000 sq miles (108,780 sq km) in the northern and
western part of the state, and Nevada Power, which serves the
greater Las Vegas area. With ON Line achieving commercial
operation on Jan. 1, 2014, the two operating companies are
now directly connected and can share generating resources
from 10 separate power plants and 38 renewable energy proj-
ects in Nevada.
This energy independence will help the utility to provide
even greater reliability and customers can avoid paying thehigh costs of purchased electricity outside of its control area
during the hot summer months when electricity on the market
is at a premium.
Safe and SoundAt the height of construction, more than 400 workers con-
tributed to the project. Not counting the thousands of hours
for planning, management, engineering and other support
services, more than 725,000 work hours were spent on specic
construction and environmental services. Safety was a key pri-
ority emphasized before a single shovel of dirt was turned and
stressed each day on the job. Remarkably, the total lost-time
incident rate came in at a low 1.10, but even one accident that
resulted in injuries was too many.
Not only was the project safe, but its leadership successfully
guided the construction process through several challenges
associated with working around sensitive species, in extreme
hot and cold environments, in high-wind conditions and
through necessary technical changes.

Does Big Data Provide
Enhanced Insight?Even before the smart grid, there were manyinformation technology challenges and struggles.Now, the data alone can overwhelm.By Mathieu Viau, Institut de recherche Hydro-Qubec
Evolving technologies, including the smart grid, can
provide electric power utilities with unprecedentedcapabilities for forecasting demand, shaping cus-
tomer usage patterns, preventing outages, optimiz-
ing unit commitment and more. At the same time, these ad-
vances also generate unprecedented data volume, speed and
complexity. One aspect of the smart grid evolution is the om-
nipresence of communications and information technologies
(IT) to have better knowledge of the state of the grid and to
make more efcient decisions.
To manage and use this information to gain insight, utili-
ties such as Hydro-Qubec must be capable of high-volume
data management and advanced analytics to transform data
into actionable insights.When thinking about the smart grid, it is far from obvious
the electric utility industry has all the answers on what IT ar-
chitecture will support it. Even before the smart grid, utilities
were struggling with IT challenges. But the smart grid brings
the big-data dimension, which can make things even more
challenging.
More and More DataBig data is known as the four Vs. It is not only about mas-

sive amounts of data represented as volume, it is also veloc-
ity, variety and veracity. Velocity is the speed at which utilitiesget the data. A phasor measurement unit is a good example.
Variety is the heterogeneity of the different sources of data.
The last dimension of big data, but not the least, is veracity.
The veracity of the data is about its accuracy and truthfulness.
Improving the veracity of data requires minimizing the occur-
rence of different sources of errors. These sources are related
to inconsistencies, duplication and missing data.
In a recent survey, IBM found one in three business leaders
do not trust the information they use to make decisions. Gart-
ner research shows that poor data quality is cited as the No. 1
reason for overrunning project costs. According to The Data
Warehousing Institute, the cost of bad, or dirty, data exceedsUS$600 billion for U.S. businesses annually. In an infograph-
ic, InsightSquared stated the following:
Data quality best practices can boost revenue by 66%.
Poor data quality across business and government costs
the U.S. economy $3.1 trillion a year (insidearm.com).
Data quality is a barrier for adopting business intelli-
gence/analytics products for 46% of survey respondents.
Electric power utilities need accurate data and cross-
sectional information to make valuable business decisions.
