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.

Southern's New Nuclear Reactors at Plant Vogtle Fall Behind Schedule

LCG, February 4, 2015-Southern Company's nuclear expansion project at Plant Vogtle may be delayed by 18 months, according to a recent regulatory filing by Georgia Power, a Southern Company subsidiary. The prime contractors, Westinghouse Electric Co. LLC and CB&I, informed Southern that the two nuclear reactors that are currently under construction are behind schedule and are now planned for completion in the second quarter of 2019 and the fourth quarter of 2020. The reactors were initially scheduled to be completed in 2016 and 2017. Project costs may also rise by upwards of $720 million.

The $14.5 billion project at Plant Vogtle will add two AP1000 reactors, each with an electric generating capacity of approximately 1,117 MW. The existing plant includes two, 1,215-MW nuclear reactors that began commercial operation in 1987 and 1989. The reactors are operated by Southern Nuclear Operating Company. The two existing reactors are owned by Georgia Power (45.7%), Oglethorpe Power Corporation (30%), Municipal Electric Authority of Georgia (22.7%) and Dalton Utilities (1.6%). The new reactors will have the same ownership.

A Georgia Power spokesperson stated that the Plant Vogtle expansion will have less impact on customer rates than originally expected, even with the delays. "The project was originally certified assuming a 12 percent increase in customer rates.With the financing and other benefits of the project that Georgia Power has proactively pursued, and the fuel savings of nuclear, the overall impact on customer rates is currently projected to be 6 to 8 percent. This is not expected to change with the revised forecast."

Southern also stated that they and the other owners participating in the project will have the right to recover from the contractors financial damages caused by the delays, although it is likely that the contractors will contest those claims.

Oglethorpe Power stated, "We expect that each additional month delay beyond the previously projected in-service dates for Vogtle Units No. 3 and No. 4 of the fourth quarter of 2017 and the fourth quarter of 2018, respectively, would increase our previously disclosed project budget of $4.5 billion by approximately $28 million per month."

In August 2008, Georgia Power filed an Application for Certification of Vogtle Units 3 and 4 with the Georgia Public Service Commission (PSC), and the Georgia PSC approved the need and cost effectiveness of the project in March 2009. The Nuclear Regulatory Commission issued the Construction and Operating Licenses (COLs) for Vogtle Units 3 and 4 in February 2012.
