General Compression Names Rahul Yarala Chief Technology Officer – Turbine Development

General Compression, Inc., the pioneer of dispatchable wind power, today announced that Rahul Yarala has joined the company as Chief Technology Officer -- Turbine Development to lead the development of General Compression's Dispatchable Wind Turbine System. Yarala previously was Director of Engineering at Clipper Windpower, Inc.

"Rahul's experience in taking wind turbine technology from concept to operation will be a tremendous asset to General Compression," said CEO David Marcus, making the announcement at the American Wind Energy Association's (AWEA) WINDPOWER Power 2007 Conference and Exhibition (Booth A111) at the Los Angeles Convention Center. "His appointment shows that we are on track in executing our development plan."

"I am delighted to be joining General Compression," said Yarala. "The technology underlying the Dispatchable Wind Turbine System will truly change the economics of generating power by wind energy."

Yarala was responsible for all mechanical design aspects of Clipper's Liberty 2.5 MW wind turbine from concept to operation. He has 15 years of experience in new product development, mechanical engineering and product management, technology management, design and manufacturing operations, including previous positions with RainBird Corporation, Emerson Electric Co., Reyco Industries, Inc. and CAT Inc. (Automated Analysis Corporation). He has three U.S. patents pending.

Yarala earned his MBA from the University of Kansas, his MS degree in Mechanical Engineering from the University of Missouri-Rolla/Northern Illinois University and his BS degree in Mechanical Engineering from Osmania University in India.

About General Compression:

General Compression is dedicated to making wind energy available on demand. Dispatchable wind energy can be sold when prices are high, and stored when prices are low. This vision is powered by the Dispatchable Wind Turbine System, which has three components: a compressed air wind turbine, a pipeline network that collects and stores compressed air, and a power plant of expanders and generators. By shifting the time when power is sold, the wind project can sell power on peak at a higher price, be more compatible with the needs of the grid, and become eligible for capacity payments. This solution will double the profitability of wind farms.

The turbine is powered by a revolutionary new compressor. When the wind blows, lift is created on the turbine blades, spinning the compressor inside the nacelle. The compressor pumps air to over 100 atmospheres of pressure and sends the air down the tower into an underground network of high-pressure pipes.

The high-pressure pipeline network collects and stores 6-12 hours of energy. If the project is sited near a geologic feature such as a salt dome, aquifer, limestone cavern, or depleted gas field, energy storage times can exceed weeks and even months.
