Massive Hydrogen-Capable CCGT Project in Texas

A 1.2-GW hydrogen-capable combined cycle power project that Entergy Texas has proposed to build in Orange County, Texas, will be spearheaded by an engineering, procurement, and construction (EPC) consortium led by Mitsubishi Power, Sargent & Lundy, and TIC.

Construction of the $1.19 billion Orange County Advanced Power Station (OCAPS), which received the Public Utility Commission of Texas’s (PUCT’s) approval in January, is slated to begin this year. When completed in 2026, the plant will replace three units—Sabine 1, 3, and 4, boiler steam turbine units with a combined capacity of 1 GW—which are slated to be retired by 2026.

OCAPS, notably, will be equipped with Mitsubishi Power’s hydrogen-capable power train which includes two M501JAC enhanced air-cooled gas turbines, a steam turbine, a heat recovery steam generator, and an advanced control system.

The massive dual-fuel project is located near Bridge City, within the largest industrial region in the nation. It will also serve the Midcontinent Independent System Operator (MISO). In documents filed with the PUCT, Entergy said the project was needed to provide reliable, dispatchable generation to the region, which could suffer an energy deficit of 9.2 TWh when the Sabine units are retired.
