Capstone Turbine Receives Underwriters Laboratories Certification for Its C1000 Series Product

CHATSWORTH, Calif., June 8, 2010 (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 has received Underwriters Laboratories (UL) certification for its C1000 Series products in accordance with UL 2200 and UL 1741.

"Receiving the UL certification allows us to aggressively sell the C1000 series of products in the United States," said Jim Crouse, Capstone's Executive Vice President of Sales and Marketing. "We have had great success selling the C1000 series product outside of our home market. We hope to drive the same success in the U.S."

"We are pleased to have achieved this significant milestone for the new C1000 series product," said Darren Jamison, Capstone's President and Chief Executive Officer. "This will open the megawatt scale U.S. market for distributed generation, energy efficiency and renewable biogas solutions to Capstone. We have already received orders for C1000s in New York, Philadelphia, Chicago and Los Angeles, and with the Obama administration's focus on increased energy efficiency, renewable portfolio standards and lower greenhouse gas emissions, we expect U.S. orders for the C1000 series to increase over the coming years," added Jamison.

The C1000 is a compact and robust one megawatt power system that provides the same low emissions, low noise, high efficiency and extended maintenance benefits of Capstone's C30, C65 and C200 offerings. It features Capstone's patented air bearing, remote monitoring and diagnostic capabilities and integrated utility synchronization and protection. The small, modular C1000 systems allow for simple and low-cost installation. Five- and nine-year Factory Protection Plans ("FPP") are available as with Capstone's other offerings, providing customers with fixed maintenance costs over the term of the FPP.
