Briggs Solar is a proposed solar generation project with a total capacity of 309.6 MW, located in Haskell County, Texas. The project, developed by Briggs Solar, LLC, is interconnected within the ERCOT region and is linked to the existing Briggs Solar, LLC operating plant (EIA ID 66691).
The project is listed in the ERCOT interconnection queue as entry ERCOT-23INR0059, with an initial queue entry date of August 4, 2020. The proposed commercial operation date is April 15, 2028, and the project's interconnection agreement status is currently in the Facility Study phase. Recent news coverage has discussed this development project.
