Summary:

The Los Angeles Residential Energy Transition (L.A. RESET) Tool estimates how household energy use and bills across Los Angeles will be affected by two major factors: the transition to renewable energy and home electrification. UCLA researchers designed the L.A. RESET Tool for the L.A. Department of Water and Power (LADWP) to inform the LA100 Plan, the utility’s roadmap to achieve 100% carbon-free electricity.

This technical guide documents the tool’s logic, data sources, capabilities, scenarios, and variables. The 2026 technical guide reflects updated LADWP electricity rate projections and a modified household income estimation method. The 2025 handbook documents the original tool design and data as presented in the 2025 report, “Impacts of Household Electrification on Energy Affordability in Los Angeles.” The original handbook was developed with a high level of detail for use by LADWP staff and is available here for documentation purposes. The updated guide has been simplified to be more accessible.

This work was funded by LADWP through the LADWP/UCLA Memorandum of Agreement. The UCLA Sustainable LA Grand Challenge provided coordination and support for this project.
