Burns & McDonnell Constructing 30 MW BESS for RWE Renewables

Burns & McDonnell will provide engineering, procurement and construction (EPC) services for the Texas Waves II project, a 30-MW/ 30-MWh lithium-ion stand-alone battery energy storage system (BESS) in Scurry County, Texas.

The project is expected to be online by year’s end.

This battery system will make a meaningful contribution to grid reliability by providing the system operator a backup for lost generation. Additionally, the system has the potential to help reduce the cost of energy to the consumer by storing energy when it is readily available from renewable resources and discharging when energy would otherwise have to be provided from more expensive fossil fuel generation.

The system connects to a key local substation that collects renewable energy from the co-located existing Pyron wind farm and supports the continued growth of renewables in the area.

The project will consist of owner-provided CATL EnerOne battery racks populated with lithium iron phosphate (LFP) battery modules. Burns & McDonnell will provide all engineering services for the project, and additionally will self-perform installation of the racks, medium-voltage power station (MVPS) and all balance of system (BOS) equipment.

The scope of work provided by the firm includes furnishing custom-designed AC auxiliary panels for battery management system and chiller power. Additionally, Burns & McDonnell will be providing modifications to the existing collection substation, including installation of a new 34.5-kV vacuum breaker, interconnection details, protective relaying and metering upgrades.
