We were the integrated engineer-procure-construct (EPC) services contractor for this 100-MW/200-MWh storage project that delivers power to the grid to support peak demand in south Texas during the hottest summer months.

The Fort Duncan storage project in Maverick County operates on a merchant basis, storing and dispatching power to the Electric Reliability Council of Texas (ERCOT) grid in response to market demand. The electricity stored and delivered during a two-hour cycle is equivalent to meeting the needs of 66,100 households.

Our team’s EPC services included conceptual and detailed design — electrical, civil and structural — as well as self-perform of the above- and below-grade electrical and equipment installation. All piles and substation structural steel were fabricated by our in-house fabrication division, AZCO. We also completed self-perform construction of a new utility switchyard and collector substation for the Fort Duncan battery energy storage system (BESS) project.
