Capstone Turbine Corporation Names Western Energy Systems Its Distributor in Northern California, Alaska, Hawaii, Oregon and Washington

CHATSWORTH, Calif., May 10, 2010 (GLOBE NEWSWIRE) -- Capstone Turbine Corporation (www.capstoneturbine.com) (Nasdaq:CPST), the world's leading clean technology manufacturer of microturbine energy systems, has named Western Energy Systems its distributor in Northern California, Alaska, Hawaii, Oregon and Washington.

Headquartered in Brea, California, Western Energy Systems, part of Penn Energy Solutions and a subsidiary of Penn Power Group, is a clean tech, green business that provides comprehensive energy-efficient power generation equipment and service solutions. The firm has an extensive customer base along the West Coast.

As a full-service Capstone distributor, Western Energy Systems will sell and service low-emission Capstone microturbines that produce 30 kilowatts to 5 megawatts of reliable power to a variety of markets, including manufacturers, educational institutions, office buildings, oil-and-gas producers, hospitals, mining operations, data centers, hotels, landfills and more.

Reliable and low-maintenance Capstone energy systems are ideal for use in combined heat and power (CHP) and combined cooling, heating and power (CCHP) applications. With U.S. government emissions standards becoming increasingly more stringent, clean-and-green Capstone turbines and microturbines are an ideal on-site energy system. The highly efficient microturbines can operate on a variety of fuels, including natural gas, methane, diesel, biodiesel and propane.

"Western Energy Systems already has a depth of experience selling CHP and CCHP into all types of markets," said Jim Crouse, Capstone's Executive Vice President of Sales and Marketing. "They have the facilities, service technicians and experienced CHP professionals available to work with customers in a range of markets. The company has an established network throughout the West Coast."

"Capstone's ultra low emission microturbine systems are a great sustainable power generation option for the customers we serve," said Al Clark, President, Western Energy Systems. "Capstone's technology is more important than ever since stricter emissions requirements are forcing companies with traditional energy systems to explore cleaner power sources."
