Research Themes +
Energy Technologies Area (ETA) researchers are continually building on the strong scientific foundation we have developed over the past 50 years. We address the world’s most pressing climate challenges by bringing to market energy-efficient innovations across the buildings, transportation, and industrial sectors. ETA is at the forefront of developing better batteries for electric vehicles; improving the country's aging electrical grid and innovating distributed energy and storage solutions; developing grid-interactive, efficient buildings; and providing the most comprehensive market and data analysis worldwide for renewable technologies like wind and solar.
Strategic Initiatives +
The Energy Technologies Area (ETA) Strategic Plan is the guiding force for our research and development for the next ten years. It clearly charts a path toward clean-energy solutions and focuses on five detailed Strategic Initiatives. The Plan provides an in-depth look at how ETA is accelerating research to provide affordable, clean energy to all while accomplishing deep, economy-wide decarbonization, looking to avoid a rise in global average temperature while simultaneously developing solutions to increase humanity's resilience to extreme weather volatility.

Abstract

Cost-effectiveness evaluations compare energy efficiency’s benefits and costs for helping judge whether to expand, retain, revise, or eliminate efficiency programs or specific measures. Such evaluations also provide feedback on whether efficiency is an effective investment, compared with other resource options.

Nationwide, utility-customer funded efficiency measures, projects, programs and portfolios have historically been assessed through integrated resource planning processes or via standard tests defined in the California Standard Practice Manual. In addition, a new cost-effectiveness guide, the National Standard Practice Manual (NSPM), was just published last month. The NPSM builds and expands upon the California manual and is targeted for use by regulators and all stakeholders interested in assessing efficiency. The NPSM includes a seven-step process for determining jurisdiction-appropriate test(s).

This webinar will discuss the basics of cost-effectiveness assessments for utility customer-funded efficiency portfolios as well as issues and options that should be considered when (a) assessing cost-effectiveness, (b) selecting which test(s) to use, and (c) quantifying the components of tests (e.g., non-energy impacts, measure costs). A new U.S. DOE Residential Energy Efficiency Cost-Effectiveness Tool will also be briefly discussed. As examples, representatives from Washington and Georgia state utility commissions will present on how they address efficiency cost-effectiveness.
