Nevada Public Utilities Commission approves NV Energy's plan to join CAISO's Extended Day-Ahead Market (EDAM)

The Nevada Public Utilities Commission approved NV Energy's plan on April 3, 2026, to join the Extended Day-Ahead Market (EDAM) operated by the California Independent System Operator (CAISO), with implementation scheduled for fall 2028. NV Energy, owned by Berkshire Hathaway Energy, operates about 6.6 GW of capacity and sources 3.7 GW of renewable energy primarily from solar power purchase agreements, with an additional 1.4 GW of renewable PPAs in development. The utility also owns critical transmission assets, including the 500-kV One Nevada transmission line, and is developing the $4.2 billion Greenlink project in Nevada, set for full operation by 2029. NV Energy expects to save $93.1 million annually by joining EDAM through lower production costs, increased market sales revenues, and higher short-term wheeling revenues. Google supported the plan, citing access to diverse resources including low-cost solar from California and wind from the Pacific Northwest and Idaho, which complement NV Energy's solar production patterns. The decision strengthens grid reliability and operational efficiency across the Western Interconnection, according to Advanced Energy United, which highlighted Nevada's strategic position connecting multiple regional power markets.
