The Sepanta Solar project is a proposed solar generation facility with a total capacity of 217.26 MW. The project is located in Nolan County, Texas, and is being developed by BREG - Belgian Renewable Energy Group. It is currently in the ERCOT interconnection queue as project ERCOT-23INR0473, with an interconnection queue entry date of October 18, 2022. The proposed commercial operation date is September 18, 2029, and the project's interconnection agreement status is currently in the Facility Study phase.
The point of interconnection (POI) is at the 1339 ESKOTA_9 138kV substation, adjacent to the Oncor Sweetwater Eskota Switch #1339. The project has appeared in recent news.
