EIA Presents Analysis of California's Solar and Wind Power Curtailment Challenges

LCG, May 29, 2025--The U.S. Energy Information Administration (EIA) released an analysis yesterday showing that the California Independent System Operator (CAISO), the grid operator for most of the state, is increasing its curtailment of the rapidly growing solar- and wind-powered generation facilities in order to balance electricity supply and demand, which is necessary to maintain a stable electric system.

Outlook for Mohave Coal Plant Uncertain

LCG, October 20, 2004--The outlook for the Mohave Generating Station remains uncertain, as Southern California Edison moves closer to decision milestones with its 35-year operating permit, which expires at the end of 2005. Expected upgrades required at the 1,580 MW plant are estimated to cost $1.1 billion, including the installation of pollution control equipment required under a 1999 consent decree. If the upgrades are made, the plant could reopen in 2009 or 2010.

The coal-fired station, located on the Arizona-Nevada border near Laughlin, Nevada, is partially owned by the Salt River Project. The plant receives coal via a 270-mile coal slurry line originating at the Black Mesa Coal Mine, operated by Peabody Energy Corp. Key issues include obtaining water supplies from the Hopi and Navajo tribes, who have been unwilling to allow the pumping of groundwater for mining beyond 2005. Southern California Edison has stated that it is not willing to invest in the upgrades without a binding agreement for water and coal for the plant until at least 2026.

If the large, coal-fired, station is shut down, its loss would be noticed, as there is limited base load generating capacity in the region that is not fueled by natural gas.
