PROJECT

Battery Energy Storage Systems (BESS)

Our team provided engineer-procure-construct (EPC) services for three 10-megawatt (MW)/20-metawatt-hour (MWh) lithium-ion stand-alone battery energy storage systems (BESS) in West Texas.

The project provides grid-stabilizing storage capacity in one of the most active wind resource areas in the United States. Referred to as the Texas Trio, the BESS sites were energized successfully after an aggressive five-month construction timeline.

The team developed innovative construction and installation techniques to help achieve schedule goals. AZCO, the union construction arm of Burns & McDonnell, fabricated a custom battery module jig that enabled our construction teams to lift and install four modules into racks at a time. Other schedule delays were offset by the use of mobile generators to allow commissioning work to begin before full interconnection.

Our team aided in the design and procurement of the battery enclosures. After the team installed the foundations and battery enclosures were set on-site, JH3 and JH4 battery modules were installed in the owner-provided racks. The enclosures included gas and fire detection.

The three sites were designed, installed and commissioned on the accelerated schedule during an unusual rainy season in West Texas. The projects required extensive coordination with Perfect Power (a SER Capital Partners portfolio company), public utility Oncor, the Electric Reliability Council of Texas (ERCOT) and local authorities. Sites were chosen in part because of proximity to Oncor substations, allowing power to be put on the grid efficiently.
