TOCE BESS 1 is a proposed 205.2 MW battery storage project located in Wharton County, Texas. The project, developed by TOCE BESS 1, LLC, is interconnected within the ERCOT region and entered the interconnection queue as ERCOT-25INR0293 on October 13, 2023. The proposed commercial operation date is May 31, 2028, and the Interconnection Agreement (IA) was executed on December 30, 2024. The point of interconnection is the 138 kV Danevang Switching Station (Bus# 5546).
The development has been the subject of recent news coverage.
