April 2012 – Capstone Turbine Corporation (www.capstoneturbine.com) (Nasdaq:CPST), the world’s leading clean technology manufacturer of microturbine energy systems, today announced it continues to expand its presence in the Eagle Ford Shale Play with the sale of 30 more C65 microturbines.

Capstone distributor Horizon Power Systems (Pumps & Service) secured this follow-on order to support multiple users’ growing power needs. The latest order for 30 low-emission C65 microturbines brings the total sold in excess of 150 units in the last nine months.

The majority of the 150 microturbines will operate on natural gas to generate clean-and-green prime power for Lease Automatic Custody Transfer (LACT) units and transfer stations at remote well sites in the Eagle Ford Shale Play.

“These multiple follow-on orders indicate that Capstone microturbines are quickly becoming the chosen power system to meet growing needs of major oil & gas producers operating in the Eagle Ford Shale Play,” said Sam Henry, Horizon Power Systems President. “This order, along with the recent 10 MW order for C1000 Series products, proves we are making serious inroads in meeting the customer’s high-caliber power needs with Capstone innovative technology.”

“Just like the North American shale gas market, Capstone oil & gas sales are expanding rapidly and made up approximately 60% of Capstone’s total revenue through the first three quarters of Fiscal 2012,” said Darren Jamison, Capstone’s President and Chief Executive Officer. “From the remote oil fields of Russia to the Shale Plays of Texas, Capstone’s durable, low-emission, and highly-efficient microturbines are becoming a proven solution for around-the-clock production and optimized well performance worldwide, ” added Jamison.
