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
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.
Book Chapter: Smart Grids: An Optimized Electric Power SystemFuture Energy: Improved, Sustainable and Clean Options for our Planet, Elsevier Science; 2nd edition (January 7, 2014)
Jerry Jackson, Leader and Research Director, Smart Grid Research Consortium
Abstract: The “smart grid” reflects the most exciting paradigm change to impact the electric power system since its beginnings more than a century ago. Smart grids apply new metering, communications and control technologies and strategies to provide an optimized power system that integrates distributed energy resources and electric customer participation in maximizing power system efficiency and reliability. Smart grids will also contribute to achieving energy efficiency, conservation, power plant emissions goals. While the smart grid concept can be described relatively easily, the transition to smart power grids presents financial evaluation challenges that are unique to these new technologies and applications.
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.
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.
Article: Evaluating Smart Grid Investments at US Cooperative and Municipal Utilities
Abstract: A twelve-member utility Smart Grid Research Consortium was formed in May 2010 to assess the state of smart grid investment analysis at US cooperative and municipal utilities and to develop a Smart Grid Investment Model for each individual member utility. The study was completed in January 2011 with delivery of the model to each utility. This article presents the results of the Consortium’s nationwide survey of utility smart grid activity, describes smart grid investment modeling issues and modeling objectives pursued in the Consortium project and presents several observations based on Consortium smart grid investment evaluations.
Presentation: Smart Grid Research Consortium/Smart Grid Investment Model
Abstract: This PowerPoint presentation presents Smart Grid Research Consortium objectives, describes the Smart Grid Investment Model, illustrates Model evaluations of several investment analyses and issues an invitation to join the 2012 Smart Grid Research Consortium.
