Dresser-Rand to build compressed air energy storage for ERCOT

The Apex Bethel Energy Center would be the company's first compressed air energy storage facility since the Power South facility in McIntosh Alabama

Dresser-Rand Group Inc. won a project award from Apex Compressed Air Energy Storage LLC for the supply of equipment to be used in a new 317 MW compressed air energy storage facility to be constructed near Tennessee Colony, Texas in the Electric Reliability Council of Texas (ERCOT) market.

The Apex Bethel Energy Center would be the company's first compressed airenergy storage facility since the Power South facility in McIntosh Alabama, which was built in 1991. Dresser-Rand's portion of the contract is valued at about $200 million.

Dresser-Rand will use its SMARTCAES technology, which provides two different services — high-pressure air compression and electric power generation derived from expanding the compressed air. Industry sources estimate that there are more than 40 such projects being contemplated over the next 5 to 10 years, according to the company.

Dresser-Rand will manufacture the compression and expansion trains for the Bethel Energy Center at its facilities in Olean and Wellsville, N.Y. The project scope also includes transportation of the equipment to the Texas site, testing, placement in operation and training.
