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.

Minnesota Nuclear Plant Relicensing in Doubt

LCG, Mar. 12, 2003--The Prairie Island nuclear plant owned by utility Xcel Energy Inc. may have a chance to continue operating beyond 2007 if a bill now circulating in the Minnesota legislature allows storage of nuclear waste at the plant site to be increased.

The bill is not seen as having strong support at present, but would be essential if the Prairie Island plant is to avoid being decommissioned. On-site storage limits are a condition of receving a license, and present increases in storage needs would lead to the limit being reached in 2007, according to XCel. Xcel had planned to replace a steam turbine at Unit 1 in 2004, but will not proceed without assurances that the 1,100-megawatt plant has a future.

Were Prairie Island to be forced to shut down, Xcel has talked to two power suppliers about alternative means of obtaining energy. Thus far, it has revealed it could sign a contract with Calpine for output from two plants of roughly 550 megawatts each, one gas-fired and the other coal-fired. The current uncertainty over storage adequacy increased following the denial of a license to a private company wishing to store waste on a Native American reservation in Utah.
