White Paper: 7 Reasons Why Smart Grid Investments Fail
July 29, 2014
New Study Identifies Pitfalls and Recommendations

Abstract: This Smart Grid Research Consortium (SGRC) research report cautions electric cooperatives and municipal utilities about pitfalls in achieving expected returns on smart grid investments.

For years, industry publications have touted smart grid cost-benefit study results that found smart grid investments more than paying for themselves with reduced utility costs. Smart grid investments seem like the perfect new technology application, transforming utility business practices, provide grid control capabilities that improve efficiency, provide enough cash flow to cover interest and principal payments and even give some rate relief. Those results can often be achieved if utility and customer characteristics are right, if smart grid investment strategies are designed appropriately and if implementation proceeds as planned.

However results at a growing number of utilities show that these conditions are often not met requiring unanticipated rate increases to make up for shortfalls in realized savings. The report identifies seven important reasons for disappointing smart grid investment returns including:

1. Vendor/integrator business case analysis
2. Absence of risk analysis
3. Failure to quantify unique utility and customer characteristics
4. Subjective system integrator/prime contractor selection
5. Software performance failures
6. Inadequate post-AMI implementation strategies
7. Insufficient utility due diligence

Each of the seven pitfalls is described in detail in the report along with recommendations to avoid each problem. The paper concludes with recommendations to “fast-track” certain smart grid benefits.

“One of the interesting findings in our study was that many utilities who fail to achieve ROI targets are also failing to take advantage of opportunities to significantly improve smart grid investment returns. Traditional cautious utility approaches are unnecessary and detrimental to financial outcomes for certain smart grid initiatives. For example, the EPRI Guidebook for Cost/Benefit Analysis of Smart Grid Demonstration Projects (December 2103) suggests that “after the VVO/CVR system is installed and tested, the efficacy of CVR will be examined through two years of day-on/day-off operation that will provide data to feed a regression analysis.”

However, information from smart meters can be used in day-ahead experiments and real-time applications to fine-tune CVR applications as soon as smart meters begin transmitting information, two years in advance of the EPRI recommendation. Two years of CVR savings can be enough in some cases to pay one-third to one-half the cost of the AMI system that is providing this information. Similarly, delayed implementation of customer engagement programs dilute savings as these benefits remain unrealized long after they could be effective.

This last observations suggests that utilities who have embarked on smart grid projects should reassess post AMI project development and implementation plans as the project proceeds.

White Paper: Low-Cost CVR May Pay for Your AMI System
February 6, 2014
New Study Turns Traditional Smart Grid Business Case Analysis on its Head

Abstract: A recently-completed Smart Grid Research Consortium (SGRC) study identifies a new smart grid investment strategy that can transform a poor AMI business case into an attractive investment. Many electric cooperatives and public utilities have rejected AMI systems because expected meter-related benefits are not compelling enough to outweigh costs. Adding demand response savings boosts benefit-cost ratios; however, the uncertainty and long lead times surrounding these customer engagement programs add more risk. Adding distribution automation (DA) benefits and costs including customer valuations of improved reliability provide added costs and benefits but leaves utility decision-makers skeptical.

This new SGRC study shows that the combination of AMI and low-cost conservation voltage reduction enabled with smart meters can provide a compelling business case for many of these utilities with little risk.

This study turns the traditional smart grid business case analysis approach on its head: instead of viewing AMI as the foundation, then adding demand response and then distribution automation benefits and costs, the analysis started with a joint AMI/low-cost conservation voltage reduction (CVR) strategy as the foundation for the business case. The low-cost CVR provides significant benefits and, because it is enabled with smart meter data, more than makes up shortcomings in the stand-alone AMI business case for many utilities without going on to more speculative smart grid benefits. A significant advantage of this new strategic approach is that costs and benefits of individual AMI and CVR elements can be determined with considerable certainty prior to initiating the project. In addition, the low-cost CVR component can be developed simultaneously with the AMI implementation avoiding the long delays that many utilities are experiencing with customer engagement infrastructure development. The CVR strategy requires utility distribution information including some voltage-demand experiments; however, this information is inexpensive to collect and analyze with our Smart Grid Investment Model.

The CVR strategy considered here is low cost, averaging about $15,000 per feeder for controls, communications and installation with no new investments voltage regulators or capacitor banks. This CVR strategy uses smart meters for voltage metering, retrofitted controls and communications to existing feeder equipment, where appropriate, and lowers and “ tightens” grid voltage control at during peak periods.

This study and its implications for utilities are noteworthy for six reasons:

  • The AMI/low-cost CVR strategy reflects a new paradigm for smart grid business case analysis
  • The analysis quantifies an often omitted contribution of smart meter data,
  • Results illustrate the incremental financial value of limited, low-costs CVR grid improvements enabled by smart meter data,
  • The financial value of this strategy is easy to verify beforehand,
  • The CVR portion can be implemented simultaneously with the AMI implementation, and
  • Contributions of smart meter-enabled CVR can turn a negative AMI business case positive

Study analysis is based on results from a recently completed SGRC CVR study conducted for an electric cooperative utility and data on electric coops and municipal utilities drawn from existing CVR, and other smart grid pilot studies and implementations.

This paper includes summary results of the new study for a generic electric cooperative utilizing the Consortium’s Smart Grid Investment Model along with a description of the Consortium’s AMI/low-cost CVR applications assessment and implementation services.

White Paper: Who Will Control Your Customers' Thermostats and what are the Implications for Your Rates? December 2, 2013
Selected Results from a Smart Grid Research Consortium Study of Programmable Communicating Thermostat Programs

Abstract: Coops and public utilities can potentially reap large savings with new programmable communicating thermostat (PCT) programs -- while ignoring PCT opportunities exposes customer relationships to third-party providers whose initiatives may increases in customers' rates.

It’s time to reevaluate residential programmable communicating thermostat (PCT) programs, regardless of whether a program is already in place. Big changes have taken place recently in PCT technologies and programs. Compared to several years ago:

  • PCT costs have dropped dramatically with PCTs that provide basic control functionality available for less than $100
  • PCT functionality has increased including capabilities such as provision of HVAC maintenance diagnostics, and voice recognition,
  • Control strategies have become more sophisticated and individualized to individual dwelling units and address “bounce-back” and other program complications, and
  • Many PCTs do not require an AMI infrastructure.

Nearly all utilities can develop PCT programs that provide utility and customer value and many utilities and their customers can potentially reap large savings with these technologies. These PCT advances also define a huge mass market potential for third-party PCT program providers as evidenced by the growing number of companies in this space. While utility/third-party PCT provider relationships can provide net benefits to a utility and its customers as described later in this paper, utilities face a risk that third-party relationships with customers will increase customer rates. Impacts differ by utility depending on power cost characteristics, customer rate structures and customer characteristics; however, customer rates will increase if participating customer bill savings are greater than utility avoided power costs. Participating customers will see bill reductions while other customers will face increased rates and monthly bills. On the other hand, third-party providers of PCT services when can potentially provide more value for participating customers and the utility than can be provided by the utility’s own program – and still make a profit. The advantage of in-house versus utility/third-party provided PCT programs depends on a variety of factors discussed in a later section.

The remainder of this article incudes a brief overview of newer PCT technology and control strategy characteristics along with an evaluation of several of the factors that impact utility PCT program potential using the Consortium’s Smart Grid Investment Model. Utility-provided versus third-party PCT program considerations are discussed in the final section of this paper.

White Paper: Score Your Smart Grid IQ (Investment Quotient), August 31, 2011

Abstract: Within a decade every utility will have incorporated at least some aspects of smart grid technologies in their distribution system. While several rating systems benchmark utility success at achieving smart grid functionality none evaluate the effectiveness of the investment planning process required to achieve the most cost-effective investment strategy. The Smart Grid Research Consortium was formed at Texas A&M University in 2010 and established as an independent Consortium in January 2011 to support electric cooperative, municipal and other public utility smart grid investment analysis. The Consortium’s experience developing and applying the Smart Grid Investment Model™ at 15 member utilities provides the basis for the Smart Grid IQ “test” presented here.

The objective of the scorecard presented in this white paper is to assist utilities in evaluating their current smart grid investment analysis and planning process. The ideal investment/planning framework, reflected by a score of 100, is capable of identifying specific technologies and programs that best meet utility financial requirements while considering unique infrastructure and customer characteristics.

For utilities who have not yet started the smart grid investment process, the scorecard provides guidance on issues to consider when developing in-house investment analysis/planning capabilities or when engaging consultants.

“We have drawn on our experience developing and implementing the Smart Grid Investment Model ™ at fifteen utilities since 2010 to provide this evaluation process,” said Dr. Jerry Jackson, Leader and Research Director of the Smart Grid Research Consortium. “This is the first benchmarking system to assist utilities in evaluating their approaches to this complex investment problem.”

Smart Grid IQ scores are compiled in six categories including: AMI/DA Investment/Planning Scope, Customer Engagement Investment/Planning Scope, Other Financial Items, Utility Customer Detail, Investment Analysis Quantitative Framework, and Ease of Use/User Interface/ Results Presentation.

White Paper: The Utility Smart Grid Business Case: Problems, Pitfalls And Ten Real-World Recommendations, August 3, 2011.

Abstract: Studies published over the past several years report impressive returns on smart grid investments. However, these studies reflect cost/benefit evaluations and models that, for many reasons, cannot be applied directly to evaluate individual utility investments. The lack of a standard, commonly accepted utility-level cost/benefit framework has led to a number of utility smart grid investment analysis approaches that poorly serve utility decision-makers.

This paper describes the challenge utilities face in developing comprehensive investment strategies and identifies difficulties associated with several common approaches to smart grid investment analysis. The final section presents ten investment analysis recommendations based on the Smart Grid Research Consortium’s cost/benefit model that has been applied at 15 utilities. These recommendations are offered both to guide utility in-house analysis and to assist utilities in evaluating smart grid analysis undertaken by vendors and consultants.
