Added transmission, varying levels of distributed generation, and increasing levels of “load modernization” are all under consideration in an NREL study. The results could illuminate paths for California and other states to reach 100% zero-carbon or renewable energy targets. Image: Webstep, Pixabay: The National Renewable Energy Laboratory (NREL) is evaluating six scenarios for the Los Angeles grid to reach 100% renewable or zero-carbon electricity by 2045 or sooner, and an advisory group is providing input. The “LA Leads” scenario, for example, would reach 100% zero-carbon electricity (including existing nuclear) by 2035—ten years earlier than state policy under California’s SB 100 . “LA Leads” would reach 100% renewables by 2045. The NREL study could give early insight regarding paths for California and other states to achieve their renewables and zero-carbon targets. The six scenarios generally begin after 2030, when the Los Angeles utility plans to reach 55% renewables in its electricity mix. Key to the study’s cost projections will be the projected costs of renewables from 2030 onward. The study will show how the flexibility to add transmission may reduce system cost, and will consider moderate and high levels of “load modernization”—that is, energy efficiency, demand response, and electrification […]
