3MW Order From Large Oil & Gas Company

December 2011 – Capstone Turbine Corporation (www.capstoneturbine.com) (Nasdaq:CPST), the world’s leading clean technology manufacturer of microturbine energy systems announced today that it received a three-megawatt order from another oil & gas producer in the Eagle Ford shale play.

Capstone continues its penetration of the North American shale gas market with another multiple megawatt order from a different Independent Oil & Gas producer in Eagle Ford. This marks the fourth major Independent Oil & Gas Producer to turn to the Capstone technology in the U.S. shale market.

Capstone distributor Horizon Power Systems (Pumps & Service), which secured the order with the new exploration and production company, expects the customer will continue to order additional C1000 Power Packages to meet their power generation needs in 2012 after the successful installation and commissioning of the first three systems scheduled to be completed in the next 90 days.

“It’s great to get another significant oil and gas producer to adopt Capstone’s cutting edge turbine technology,” said Sam Henry, Horizon Power Systems (Pumps & Service) President. “They, like other Eagle Ford producers, are understanding the high reliability and low emission benefits of the Capstone family of products and the important role microturbines can play in ensuring around-the-clock energy production,” added Henry.

The three C1000’s will provide three megawatts of clean and green prime power to central processing facilities and metering stations at remote well sites in the Eagle Ford shale play. The microturbines, fueled by pipeline quality gas, will produce electricity to provide all power to the onsite equipment, including heaters, pump motors, circulation pumps and distribution panels.

“The adoption and deployment of Capstone microturbines continues to accelerate in the worldwide oil & gas markets,” said Jim Crouse, Capstone’s Executive Vice President of Sales and Marketing. “Specifically, we continue to see very strong order activity in Russia for associated gas applications and in the Marcellus and Eagle Ford shale plays here in the U.S.,” added Crouse.
