Nevada Regulators Approve NV Energy’s Plan to Join California’s Day-Ahead Power Market

Regulators say the shift will lower costs by accessing a wider Western power mix.

Overview

  • State regulators cleared NV Energy’s Nevada Power and Sierra Pacific Power to enter the California ISO’s Extended Day-Ahead Market, a regional system that schedules power one day ahead to share resources across states.
  • NV Energy plans to begin participating in fall 2028 and estimates about $93.1 million in yearly net benefits from lower production costs, added market sales, and higher short-term wheeling revenue.
  • EDAM is set to launch May 1, 2026 with PacifiCorp and Portland General Electric, with LADWP, the Balancing Authority of Northern California, Turlock Irrigation District, and Public Service Co. of New Mexico slated to follow, and Idaho Power considering entry.
  • The commission will hold a workshop to prepare distributed energy and demand-response providers to take part in CAISO markets in line with FERC Order 2222.
  • NV Energy’s buildout of the $4.2 billion Greenlink transmission lines and the TransWest Express link delivering 3 GW of Wyoming wind into California near Las Vegas will help move low-cost solar and wind across the region.
