The Solar Energy Generating System (SEGS) III-VII project located near Kramer Junction, California, about 30 miles west of Barstow, in San Bernardino County, California. The site occupies approximately 1,000 acres (170 acres for each of the five units) and is developed on generally level desert terrain within Kramer Basin at an elevation of 2,450 feet. It is surrounded by discontinuous low-relief uplands including the Saddleback Mountains to the north and the Kramer Hills to the south and is classified as having a high desert climate. Hot and dry summers with occasional intense desert thunderstorms are followed by cool and dry winters. High winds and blowing sand and dust are frequent in the area.
SEGS III-VII consists of five 30-megawatt (MW) (150-megawatt net total) solar and natural gas fired units. Electricity produced from the project is sold to Southern California Edison.
The project owner previously suspended operation of the SEGS VI and VII facilities pursuant to a cold layup plan for VI and VII that was submitted to the CEC in September 2018. In October 2019, the project owner submitted a new cold layup plan to suspend operation at all five units (SEGS III-VII). Safe Layup activities have been completed for SEGS III-VII per the cold layup plan submitted in 2019.
Since 2005 NextEra Energy Resources (NEER) previously suspended operation of the SEGS VI and VII facilities pursuant to a Cold Layup Plan for VI & VII that was submitted to the California Energy Commission in September 2018.
On October 31, 2018, a September 2018 Cold Layup Plan for SEGS Units VI-VII was docketed (TN 225713). An addendum was docketed on August 20, 2019 (TN 229493).
On February 12, 2021, a Decommissioning Plan for the SEGS Units III-VII facility was docketed (TN 236752). On April 20, 2021, a Final Decommissioning Plan for SEGS Units III-VII was docketed (TN 237500).
On June 9, 2021, (TN238204), the California Energy Commission approved the Decommissioning Plan.
Decommissioning activites for SEGS III-V were completed on December 23, 2021 with decomissioning activites continuing with SEGS VI -VII with anticipated completion by the 3rd quater of 2022.
On February 16, 2022, the CEC approved a petition (TN 241587) to adjust the boundary removing SEGS III-V from the overall project site and terminating the CEC’s jurisdiction over SEGS III-V.
On May 24, 2022, the CEC approved a petition (TN 243268) to adjust the boundary removing SEGS VII from the overall project site and terminating the CEC’s jurisdiction over SEGS VII.
As of June 2022, SEGS VI is still under CEC jurisdiction.
