AB 174 amends energy statutes to redefine "renewable resources" for reporting purposes, explicitly including nuclear energy starting in 2026. It establishes new definitions for large-scale wind/solar systems (100+ megawatts) and battery storage, while clarifying that local governments cannot restrict energy installations more strictly than state rules. The bill affects energy developers, utilities, and local governments by changing how transmission contracts are audited and how renewable/nuclear projects are categorized. It does not create new project requirements but updates existing reporting frameworks for the state legislature and governor. The bill is pending in the Energy and Utilities Committee after being introduced in April 2025.
