The 100-megawatt Bexar battery energy storage system, developed by Goshe Energy Storage, has achieved commercial operation and NERC registration in Bexar County, Texas.

As a facility exceeding the 75 MVA threshold, Bexar BESS is required to register as a NERC Category 1 Generating Owner (GO). Radian Generation worked closely with Goshe Energy Storage during the final stages of commissioning to verify engineering controls, confirm technical alignment, establish procedures, and meet NERC CIP cybersecurity obligations, ensuring full regulatory compliance at the time of registration.

"Bringing a facility of this scale into commercial operation while meeting NERC registration requirements is no easy task. Radian's team understood our timeline, collaborated seamlessly with our engineers, and ensured we were compliant and confident the moment we went live," said Tyler Bohan, Goshe's Engineering Director.

Mill Creek Renewables is the EPC contractor for the 134 MWh Bexar BESS project, which was completed last year.
