We are providing engineer-procure-construct (EPC) services for a 125 MW/500 MWh lithium-ion battery energy storage system at the existing E.W. Brown Generating Station in Harrodsburg, Kentucky.
The LG&E and KU Brown battery energy storage system (BESS) project adds utility-scale energy storage capacity to the power grid, supporting greater flexibility as energy generation and demand patterns continue to change. Located at an existing generation site, the project connects new battery storage infrastructure with established grid assets, creating a practical path for adding dispatchable energy resources without developing a greenfield power site.
The system includes 152 Tesla Megapack 2XL BESS enclosures, 38 medium-voltage transformers, civil and structural improvements, balance-of-plant electrical work, fire protection systems, and supervisory control and data acquisition (SCADA) capabilities. The project also includes a 34.5-kV/345-kV collector substation that will interconnect with an existing 345-kV switchyard near the project site.
The project brings together battery storage, substation integration and site infrastructure within an operating power generation environment. That setting required careful planning for constructability, safety, sequencing and interconnection. By combining design, procurement and construction within one delivery model, the project team aligned equipment procurement, site work and electrical installation around the technical requirements of the storage system and the existing switchyard.
