Radian Generation Supports Successful Launch of 100 MWac BESS Project in Texas with Compliance Services

Radian Generation announces the successful NERC registration and achievement of Commercial Operations Date (COD) for the Bexar Battery Energy Storage System, developed by Goshe Energy Storage. The 100 MWac facility reached COD on March 12, 2026, with ERCOT III approval. NERC registration was completed on March 20, after a coordinated effort with Radian, and implementation of NERC compliance standards.

Located in Bexar County, Texas, the Bexar BESS is designed with a total capacity of 100 MWac, strengthening ERCOT grid reliability amid accelerating renewable energy integration. As a facility exceeding the 75 MVA threshold, Bexar BESS was required to register as a NERC Category 1 Generation Owner (GO). Radian Generation partnered closely with Goshe Energy Storage during the final stages of commissioning to validate engineering controls, confirm technical alignment, establish procedures and meet NERC CIP cybersecurity obligations, ensuring full regulatory compliance upon registration.

Tyler Bohan, Goshe’s Director of Engineering stated, "Bringing a facility of this scale into commercial operation while simultaneously meeting NERC registration requirements is no small task. Radian's team understood our timeline, worked seamlessly alongside our engineers, and made sure we were compliant and confident from the moment we went live."

Radian Generation’s engagement efforts increased as the project approached its COD, working with the project owner, EPC, and Generator Operator (GOP) to review technical documentation, operational technology design, and as-built system components. This collaborative NERC readiness process reflects Radian’s approach for utility-scale storage projects, delivering facility-specific compliance support throughout the project lifecycle.

“With COD and NERC registration complete, we look forward to continuing to support the Bexar BESS project through ongoing compliance and cybersecurity services,” concluded Haley Horgan, Account Executive with Radian Generation.
