Capstone Turbine Adds U.S. Coal Bed Methane Market to Its C200 Applications

CHATSWORTH, Calif., Feb. 28, 2013 (GLOBE NEWSWIRE) -- Capstone Turbine
Corporation (www.capstoneturbine.com) (Nasdaq:CPST), the world's leading clean
technology manufacturer of microturbine energy systems, has added the U.S.
coal bed methane market to its portfolio of oil and gas applications with the
installation of the country's first methane-fueled C200 at a CONSOL Energy gas
processing plant in Pennsylvania.

CONSOL Energy Inc. (NYSE:CNX), a leading diversified-fuel producer in the
Eastern United States, estimates the "clean-and-green" 200-kilowatt
microturbine will eliminate 6,486 tons of carbon dioxide produced from coal
bed methane from the atmosphere each year. Anticipated annual energy cost
savings is $80,000. To commemorate the commissioning of this project, CONSOL
Energy executives recently donated $7,811 to the local Charleroi Area (PA)
school district.

Capstone distributor E-Finity, headquartered in Philadelphia, PA, secured the
C200 order, which is installed at CONSOL's Fallowfield Gas Processing Plant in
southwestern Pennsylvania. The low-maintenance, highly efficient microturbine
produces 200-kilowatts of low-emission power that the plant uses to recover
18.5 million-cubic-feet (524,456-cubic-meters) of methane gas each year and
generate 1.3 million net kilowatt hours of clean electrical power.

"The C200 is expected to have much lower maintenance costs and emissions than
those from reciprocating engines," said Jim Grech, CONSOL Energy's Chief
Commercial Officer.

"As government regulations for methane emissions become stricter, we
anticipate more companies will turn to microturbines because they can easily
operate on methane gas, produce extremely low emissions, and are exceptionally
reliable," said Jim Crouse, Capstone's Executive Vice President of Sales and
Marketing.

A 2011 U.S. Department of Energy report stated, "Coal bed methane proved
reserves and production have grown nearly every year since 1989. Today it
accounts for more than 8 percent of total domestic natural gas production and
nearly 8 percent of U.S. proved reserves. The U.S. Energy Information
Administration believes coal bed methane will continue to hold a similarly
important share in the domestic energy picture between now and 2035."

"The flow rate and methane concentration of the waste gas stream are well
suited to the capacity of Capstone's C200," said Deborah Kosmack, CONSOL
Energy research engineer."The microturbine is rated to operate at 33 percent
electrical efficiency, based on a lower heating value."

"It's clear why Fortune Magazine selected CONSOL as one of America's most
admired companies," Crouse said. "They made a commitment to reduce their
greenhouse gas footprint, and their selection of a Capstone C200 is evidence
of this pledge. The C200 will significantly reduce methane gas emissions at
Fallowfield and will provide the company substantial cost savings."

The microturbine power system could qualify the plant to sell CO[2] credits
and could qualify for Tier 2 incentives under the Pennsylvania Alternative
Energy Portfolio Standard.

Unlike traditional generation technologies, microturbines are well suited to
using gas with low methane content. The Fallowfield microturbine continuously
operates with methane concentrations around 33 percent.
