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

State Engagement in Electric Distribution System Planning documents activities in eight states with statutory or public utility commission requirements for electric distribution system or grid modernization plans, plus four jurisdictions with proceedings on such requirements underway or planned. The report also looks at activities in several additional states to provide a picture of the significant variation in approaches.

Among the topics the report covers are state approaches to planning distribution systems and grid modernization investments, analyzing non-wires alternatives to traditional distribution system investments, identifying capacity of distribution systems to integrate distributed energy resources such as rooftop solar, and assessing the benefits of these resources by location.

States can learn from each other and tailor successful approaches to their unique circumstances. Reviewing the broad range of legislative and public utility commission activities described in the report — with links to key proceedings and documents — is a useful starting point.

Report authors are Juliet Homer and Alan Cooke, Pacific Northwest National Laboratory; Lisa Schwartz and Greg Leventis, Berkeley Lab; and Francisco Flores-Espino and Michael Coddington, National Renewable Energy Laboratory. The report was funded by the U.S. Department of Energy’s Office of Electricity Delivery and Energy Reliability and Office of Energy Efficiency and Renewable Energy - Solar Energy Technologies Office, through DOE’s Grid Modernization Initiative.
