GLOBALViewpoint

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.

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.

CHARACTERSwithCharacter

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?

TRANSMISSIONLine

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.
