Capstone's Natural Gas C200 Meets New Jersey Air Quality Standards for Classification as an "Insignificant Source" of Emissions

CHATSWORTH, Calif., March 29, 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 the New Jersey Corporation for Advanced Technology (NJCAT) verified that Capstone's natural gas C200 turbine meets the state's air quality regulations for being classified as an "insignificant source" of emissions.

NJCAT is a non-profit membership corporation created to promote in New Jersey the retention and growth of technology-based businesses developing innovative environmental and energy technologies. NJCAT assists developers of new technologies and services with the regulatory, commercial, financial and technological assistance required to bring their technologies to market by providing third party credible and independent verification of their technology performance claims.

"For Capstone C200 installations in New Jersey office buildings, manufacturing plants, hospitals, universities, landfills, wastewater treatment plants and other sites, NJCAT verification simplifies the air-permitting process required by the state's Department of Environmental Protection," said Jim Crouse, Capstone's Executive Vice President for Sales and Marketing.

The NJCAT verification document specifically states, "The Capstone C200 LP MicroTurbine fired with natural gas when operated at 40 percent or greater load has demonstrated by source emission testing that it emits less than 1) 0.40 pounds of nitrogen oxide (NOx) per megawatt hour, and 2) 0.25 pounds of carbon monoxide (CO) per megawatt hour; and, therefore, that it is not a significant source of NOx and CO emissions in accordance with N.J.A.C 7:27-82(f) 1.i."

Other models of Capstone microturbines have received air-quality certification or verification. In 2009, the C200 received Underwriters Laboratories (UL) certification in accordance with UL 2200 and UL 1741. In 2008, the C65 ICHP natural gas microturbine earned certification for meeting stringent California Air Resources Board (CARB) requirements for low emissions. In addition, the company's C30 microturbine demonstrated emission levels compliant with the Environmental Protection Agency and California Air Resources Board (CARB) 2010 requirements for Heavy Duty Diesel Engines in buses and other combustion engines.
