Accurately Measuring Savings from Integrated Distributed Energy Resources Offerings

Brett Feldman — January 31, 2017

AnalyticsEnergy efficiency and demand response (DR) programs have long been administered by utilities, third parties, and local governments using taxpayer or ratepayer funds. Most recently, integrated offerings that span energy efficiency, DR, and other program areas have become more feasible due to the advent of the smart grid. The integration of information and communications technologies with the power system is enabling a better balance between demand and supply side resources.

Integrated offerings are key indicators of a broader integrated distributed energy resources (iDER) future. Identifying program design and savings attribution methodologies for harnessing the benefits of these resources are critical to enabling public support for the innovators that will populate this future with integrated offerings that bundle value streams into streamlined solutions. While existing program design and funding constraints may not be able to seamlessly support these emerging technologies, avenues are opening and should be explored so as not to thwart the iDER future.

In a new white paper, Navigant presents a methodology to account for all of the energy and demand savings from an integrated energy efficiency and DR offering on an annual basis. The methodology separates the attributes of each program type while avoiding double counting of savings across programs. It also proposes methods to accurately portray the costs and benefits of each program.

Navigant recognizes that each jurisdiction has its own policies and protocols for operating an  iDER offering. Ongoing activities in New York and California provide relevant lessons in light of the states’ recent focus on iDER. Navigant used examples of these lessons to identify key considerations across three areas that integrated offerings focusing on energy efficiency and DR should consider when developing implementation plans:

  • The importance of data granularity for analysis
  • Exploring legislative channels to support integrated offerings
  • A focus on avoiding double counting benefits

Navigant draws the following conclusions from this assessment for consideration by relevant stakeholders, including utilities, other program administrators, regulators, customers, and third parties:

  • Well-established methodologies and protocols exist for quantifying energy and demand savings for energy efficiency and DR offerings across North America.
  • Advanced generation thermostats have a proven market track record of providing demonstrable benefits for energy and demand savings through established methodologies and protocols to verify and attribute savings.
  • Energy efficiency and DR programs are funded and evaluated through individualistic incentive budgets; a structure that confounds shared budgeting for cross-program functionality and hampers integrated offerings from capitalizing on their multiple value streams to gain market traction.
  • To avoid discouraging innovators from pursing integrated offerings, regulators and utilities without integrated evaluation methodologies should consider the methodology to develop interim polices and protocols for iDER offerings to count savings in two or more program areas until an integrated methodology can be developed through official channels.
