Executive Summary
U.S. smart grid expenditures have been compromisedlargely of advanced metering infrastructure (AMI) projects
over the past five years. However, many utilities are noweager to fully optimize their systems with grid automation
projects, which will allow them to fully realize the promiseof the smart grid. Grid automation will create a muchmore reliable and efficient grid, enable optimization ofthousands of grid-connected devices and distributed
generation sources, and allow for faster outage recoverytimes.
Federal smart grid deployment targets, renewableportfolio standards, and the need to increase grid
reliability have driven U.S. grid automation. However, as
electricity markets open up in the U.S., grid automationprojects will also be driven by a strong need to increaseelectric provider customer satisfaction.
As U.S. utilities embrace global standards such as IEC61850, vendors with field proven grid analytics, advanced
DMS, sensors, IEDs, and FLISR solutions will be bestpositioned in the market. The long-term result of suchinvestments in grid automation will result in a significantly
more reliable and efficient grid, higher utility customer satisfaction, and lower energy bills.
The major findings in this report show that a large majorityof U.S. utilities are ready to take up the task of building a
grid that meets the needs of tomorrow’s ConnectedEconomy. However, utilities will need strong support fromindustry stakeholders (vendors, integrators, regulators, etc.)
and electric customers to meet this goal.
About This Report
The purpose of this report is to explore the use of gridautomation and analytics among U.S. utilities, assess utility
interest in adopting global standards, and examine thelevel of concern utilities have in regard to the systemimpacts of renewable energy sources and electric
vehicles. Additionally, this report identifies key approachesand obstacles utilities face when pursuing these
advanced grid automation projects.
Methodology
Zpryme surveyed 83 U.S. utility professionals in November of
2012. Respondents were asked 23 questions. The surveywas conducted over the Internet.
Major Findings
About 3 out 4 (76%) utilities are planning to procuregrid analytics software, and they would most prefer analytics software integrated into an advanced
distribution management system (DMS).
Six out of ten (63%) plan to adopt IEC 61850
standard for substation automation. They identifiedother higher priority items, testing/validation, and a
need for assistance in implementation as the topthree obstacles that would prevent them from
adopting IEC 61850.
Seventy percent of respondents prefer to implement
an advanced DMS using multi-vendor best-of-breedcomponents (plus systems integration).

Eight out of ten respondents plan to update older existing substations with intelligent electronic
devices (IEDs) to support DMS or grid automationcapabilities.
Six out of ten respondents are very or highly likely touse a major equipment vendor to provide initial
system configuration services for grid automation.The main reasons cited for not using a major
equipment vendor for initial system configurationwere serv ice level agreement concerns for support,desire to perform “in-house” configurations, and
relationship with existing integrator.
Respondents indicated that the use of
performance-based utility rates or reliability indexes
would most likely lead to increased investment in:feeder or substation automation, replacing agingdistribution equipment, and DMS or ADMS software.
Forty-three percent of respondents described their approach to fund a distribution equipment life
extension program as retro-filling existing equipmentwith new Breakers/Switches. Thirty-seven percentsaid they replace with new equipment, and 20%
said they refurbish existing equipment. Utilities citedavailability of capital funding and downtime
(outage) considerations as the main reasons theychose their approach for their equipment lifeextension program.
About one out of five (22%) respondents indicated
that a high-penetration of (future) renewable
energy is expected to cause significant problems ontheir distribution system.
Eighteen-percent of respondents indicated that a
high-penetration of (future) electric vehicle (EV)charging is expected to cause significant problemson their distribution system.
Just over four out of ten (44%) respondents chose a
commercial and industrial customer-orienteddemand response program as their most preferreddemand management option. Another 25% chose
a grid-oriented solution, like Volt-VAR or conserv ation voltage reduction (CVR). Eighteenpercent chose a residential customer-oriented
program.
Thirty-six percent (36%) of respondents said they areplanning to assist large commercial customers withEnergy Efficiency (EE) projects to meet EE portfolio
standards requirements, with another 31% planningto implement such projects, but the improvements
are not related to Energy Efficiency PortfolioStandard requirements.

U.S. Grid Automation Survey Implications
The survey results (presented in figures 1 – 22) in this reportoffer key insights about how utilities will proceed with grid
automation projects in the near future. In this section wepresent the major implications of the data, and
recommendations that can assist in advancing gridautomation deployments.
U.S. utilities will increasingly embrace grid analytics,
thus creating significant opportunities for utilities toleverage the influx of data coming from thousands
of nodes across their entire electrical systems.Analytics will enable faster and more accuratedecisions to be made about wholesale peak power
purchases, renewable and distributed resource
integration, customer billing, outages, preventingenergy losses, and emergency response planning.The result is lower operating costs, higher customer satisfaction, and reducing unnecessary strain on grid
equipment.
A majority of utilities are prepared to embraceglobal standards, IEDs, advanced DMS, FLISR,renewable energy, EVs, and EE standards in an
effort to build a grid that can meet the needs oftoday and tomorrow’s Connected Economy.
Utilities will seek to increase large commercialcustomer ’s participation in demand response
programs. Such programs will require a higher levelof customization to meet the needs of largecustomers, and also require advanced energy
management system integration on the customer or utility side.
Utilities are going to demand higher levels of
interoperability, scalability, customer support,training, validation and testing from vendors beforeapproving expenditures on new products,
technologies, and software. In other words, small-scale testing or controlled environment use cases
will no longer be enough to gain the trust of utilities.Solutions must be proven in real-world (large-scale)deployments.

U.S. Grid Automation Trends
Data analytics, advanced substation automation anddemand response, and renewable and electric vehicle
(EV) integration are key trends in grid automation that willcontinue to shape the market in the near term.
Data results from the US Grid Automaton Survey indicatethat 73% of US utilities are planning to procure gridanalytics software. They are looking to this solution to
leverage the influx of data coming from thousands ofnodes across their electrical systems to enable faster and
more accurate decisions about wholesale peak power purchases, renewable and distributed resourceintegration, customer billing, outages, preventing energy
losses, and emergency response planning. The two
approaches most likely to be used for grid analyticssoftware are analytics integrated into an advanced DMSor a separate analytics application, and the majority ofthe respondents prefer the former approach. Nearly two-
thirds (65%) of the utilities surveyed want to use a multi-vendor best-of-breed components system, and the
remainder would use an integrated advanced DMS froma major vendor , plus system integration.
Eighty percent of the utilities that responded to the surveyplan to upgrade older existing substations with intelligent
electronic devices (IEDs) to support DMS or gridautomation capabilities. In addition, the use ofperformance-based utility rates or reliability indexes would
most likely lead to increased investment in feeder or substation automation, replacing aging distributionequipment, and DMS or ADMS software.
A trend in regard to demand response (DR) programssuggests that nearly half of US utilities are looking to
employ commercial and industrial demand responsesolutions, one-quarter prefer a goal-oriented solution like
Volt-VAR or conservation voltage reduction, and a smallpercentage (13%) prefer residential customer-oriented DRprograms.
There is a trending concern among utility executives that
high penetrations of future renewable energy and futureEV charging will create significant problems on their distribution systems.

U.S. Grid Automation Drivers
AGING INFRASTRUCTURE AND WORKFORCE
The traditional electric grid has been in place since themid-19th century, and it is aging along with the workforce
that have managed and maintained it. As with manyasset intensive industries with complex capitalinfrastructure, the workforce has grown up with their
respective utilities and the majority of them have beenemployed for their entire careers. The development andimplementation of a modern smart grid infrastructure will
require attention to workforce development to provide anumber of well-trained, highly skilled electric power sector
personnel knowledgeable in smart grid operations.
A CRITICAL NEED FOR A FAST, RELIABLEAND SECURE INFRASTRUCTURE
The smart grid integrates multiple controls and monitoringsystems onto a single IP network to help ensure high priorityis given to grid operations traffic. The network convergence enables utility companies to reduce power
outages and service interruptions, as well as to reduceresponse times by quickly identifying, isolating, diagnosing
and repairing faults. The security of such a connectedstructure from physical or cyber-attacks is of paramountimportance. The grid needs to be able to detect and
isolate any breach to minimize its effect and raise analarm to speed service restoration.
THE NEED TO REDUCE INDEPENDENCE
ON FOSSIL FUELS
The current electric system has relied heavily on fossil fuels,including oil, coal and natural gas, as energy sources.These fuels are non-renewable and the reserves available
on the earth are dwindling rapidly. The success of thefuture electric infrastructure will necessitate a heavy
reliance on renewable energy sources.
GLOBAL, FEDERAL AND STATE REGULATIONSAND TARGETS
The Federal Government has established smart griddeployment targets and renewable portfolio standards. In
addition, state-based regulatory frameworks, as well asexisting and pending state and federal legislation, havecreated road maps and targets that are critical to plan a
grid automation deployment strategy.
STIMULUS FUNDS BEING REPLACEDBY PRIVATE FUNDS
More than $9 billion is currently invested in privately fundedprojects. In addition, there is strong interest from venture
capital and private sector funding for the development ofinnovative smart grid technologies.

Demand Management Option
The next question asked the sample which demandmanagement option they preferred. Forty-four percent
said they preferred commercial and industrial customer-oriented demand response programs; 25% preferred agrid-oriented solution like Volt-VAR or conservation voltage
reduction; 13% preferred residential customer-orienteddemand response programs; and the remainder, 18%, had
another (than these three) preference.
Reasons Demand Response Option Chosen
An open-ended question asked why those demandmanagement preferences were selected (in figure 20);
and the most frequent reasons were:
Grid oriented preference
Cost savings Conserve energy
Changing grid dynamics
Commercial and industrial or iented
Ability to control load on a predictable basis Best ROI because there is a large MW control
from a few customers
Residential oriented Pass savings on to customers Let customer take control of their energy
usage
No theme emerged when some respondents said they
were not using a demand response program.

Zpryme Outlook
As U.S. utilities transition from pilot or project mode to fulldeployment mode, the grid automation market will
experience rapid transformation in the near term. Utilitiesthat have already started distribution and substationautomation will drive the growth of this market.
Progressive utilities will pioneer the use of grid analytics,advanced DMS, sensors, IEDs, and FLISR. U.S. utilities will
chart the path for global adoption of these technologies.Additionally, as grid automation deployments increase, it
will become easier for utilities to make the business case(to PUCs, communities, and investors) for investments insuch technologies.
Finally, as U.S. utilities embrace global standards such asIEC 61850, vendors will ramp up their R&D and productportfolios to be able to meet utility demand for gridautomation products. This increase in competition will lead
to lower equipment prices and increased ROIs for utilities.
The long-term result of such inv estments in grid automationwill result in a significantly more reliable and efficient U.S.electric grid, higher utility customer satisfaction, and lower
energy bills.
