Capstone Turbine Corporation Receives Third Service Blanket Order Valued at $8.6 Million From Petroleos Mexicanos (PEMEX)

CHATSWORTH, Calif., July 14, 2011 (GLOBE NEWSWIRE) -- Capstone Turbine Corporation (www.capstoneturbine.com) (Nasdaq:CPST), the world's leading clean-technology manufacturer of microturbine energy systems, today announced that it received another comprehensive fleet-wide service blanket order with Petroleos Mexicanos (PEMEX), the fourth largest crude oil producer in the world. Capstone has received service blanket orders from PEMEX since 2007 for fleet-wide service support.

This new $8.6 million multi-year service blanket order will cover PEMEX's entire 44 unit microturbine fleet. The fleet generates low-emission power for manned and unmanned PEMEX oil platforms throughout the Gulf of Mexico. PEMEX selected Capstone microturbines because of the microturbines' reliability in dangerous environments and to meet its own strict environmental requirements.

Industrias Energeticas, Capstone's distributor headquartered in Campeche, Mexico, secured this new blanket order, which ensures blanket service support coverage for PEMEX's fleet of microturbines installed on satellite platforms on the North and Northeast regions of the Gulf of Mexico. The microturbines are specially designed for hazardous Class 1 Division 2 environments.

The microturbines, which operate on sour gas and wellhead gas that flows through offshore platforms, replaced high-maintenance diesel generators. The microturbines provide continuous power for each platform's SCADA, fire and gas, emergency stop, communication, lighting, and auxiliary systems. The full service blanket order issued to Capstone ensures utmost reliability of the microturbine fleet through maintenance services, employee training, spare parts, and 24/7 technical support.

"PEMEX has been a Capstone customer since 2002," said Juan Carlos Hernandez, Industrias Energeticas' CEO. "PEMEX officials continue to issue blanket orders and add microturbines to their growing fleet to maintain PEMEX's high production levels. PEMEX is environmentally-focused and the Capstone microturbines provide them a clean and reliable generation system that run safely in hazardous locations, takes up minimal space because of the small footprint, and requires very limited maintenance. This new service blanket order demonstrates PEMEX's satisfaction with the microturbines and support we have provided to their critical operations."
