Energy Savings

Energy Savings

Purpose & Goals

The DAWG’s Energy Savings Subgroup or “‘pup” provides a forum to share and discuss electricity and natural gas load impacts from energy efficiency, including historic, current and future accomplishments of a variety of efforts designed to encourage the efficient use of energy. These include codes and standards, and programs implemented by investor-owned utilities (IOUs) and publicly-owned utilities (POUs).  Energy efficiency and demand response represent preferred resources in California, so they must be included properly in demand forecasting and resource planning.  A key focus of the subgroup is Additional Achievable Energy Efficiency (AAEE) — that efficiency which is reasonably expected to occur but is not yet “on the books” in terms of code & appliance adoption and/or program design and funding.  The group also discusses evaluation, measurement & verification (EM&V) activities related to the reporting, assembling and integrating load impacts from energy efficiency into demand forecasts and resource planning.

Topics Areas & Activities

Key Energy Savings Subgroup topic areas and activities include:

  • Contribute to the development of energy efficiency potential studies, since these serve as the basis for preparing “managed” demand forecasts used in resource planning; and, ensure that assumptions are consistent and/or compatible with demand forecasts and other resource planning assumptions used in demand forecasts and resource planning.
  • Facilitate development and characterization of energy efficiency data at levels of disaggregation for use in planning activities.
  • Improve reporting of energy efficiency impacts to include loadshapes.
  • Stay apprised of energy efficiency EM&V activities, in particular those designed to measure load impacts from IOU, POU, statewide and other significant programs.
  • Interact with data managers responsible for maintaining and publishing energy efficiency program data; and to plan for development and maintenance of a database of forecasted, reported and evaluated savings for all the state’s utilities (IOU and POU).
  • Discuss issues related to the interaction of savings claims between programs – both to address possible double-counting and to understand “market transformation/spillover” effects from multiple programs.
  • Provide periodic progress reports on agency efforts to quantify and standardize savings from standards and or programs.
  • Provide a forum for discussing and, where appropriate, coordinating activities such as goals and potential studies.
  • Address issues related to longitudinal program data collection and consistency of reported program impacts over time.
  • Discuss consistency of energy savings impacts (including baselines) across jurisdictions.
  • Address caveats to energy efficiency characterizations in prior IEPR cycles and AAEE reports.
  • Determine the appropriate metric for efficiency program peak savings.
  • Review the energy efficiency component of revised and preliminary forecasts, and comment on issues for developing those forecasts as needed.
  • Consider the effects of evolving legislation on future impacts.
  • Serve as the primary Subgroup “home” for, and interact with, the Demand Forecasting Subgroup (and possible future Potential and Goals Subgroup) on topics such as:
    • Measure decay
    • Macro-consumption metrics
    • Compilation of historical impacts
    • Behavioral impacts
    • Specification of “Total Market Gross” impact measurements, including:
    • Naturally occurring conservation
    • Net/gross savings
    • Quantification of load impacts from market transformation
    • Price effects
    • Takeback /rebound
    • Attribution of impacts to specific interventions or entities
