Capstone Secures C800 and CC125 Order to Fuel Groundbreaking Renewable Energy
Anaerobic Digester System

CHATSWORTH, Calif., June 3, 2013 (GLOBE NEWSWIRE) -- Capstone Turbine
Corporation ( (Nasdaq:CPST), the world's leading clean
technology manufacturer of microturbine energy systems, today announced it
received an order from CleanWorld Partners, an internationally recognized
technology innovator in anaerobic digestion technology and by-product
utilization. The order includes a Capstone C800 Microturbine and Capstone
Clean Cycle 125kW (CC125) waste heat-to-electricity generator.

Regatta Solutions, Inc., Capstone's distributor for California, Oregon,
Washington and Hawaii, secured the order.

The grid-connected system will be installed this summer in a combined heat and
power (CHP) application at an innovative organic-waste-to-renewable energy
facility at a university nationally acclaimed as a sustainability leader.

The ultra-low emission C800 and CC125 will provide a portion of the site's
electric load. All waste heat produced from operation of the C800 will heat an
on-site digester and, along with waste heat from the digester, run the CC125
-- all without any need for additional fuel.

Biogas produced by the digester, which sits atop a landfill, will fuel the
clean-and-green C800.

"CleanWorld has achieved widespread success in anaerobic digester solutions,
significantly reducing greenhouse-gas emissions, with scalable and affordable
solutions," said Michelle Wong, Chief Executive Officer of CleanWorld
Partners. "Capstone microturbines align with our mission to implement
effective renewable solutions that mitigate emissions and capture loss of
energy through a waste and heat conversion process."

"Using this dynamic combination of the C800 and CC125 in a renewable energy
anaerobic digester is the perfect example of how Capstone microturbines
provide cleaner, more reliable, and cost-effective power solutions," said Jim
Crouse, Capstone's Executive Vice President of Sales and Marketing. "The
CC125's Organic Rankine Cycle (ORC) captures normally wasted heat from a
variety of sources and turns the heat into clean-and-green electricity, which
significantly raises a power-system's net efficiency."

The Capstone microturbines' reliability was a key factor for the purchase.
"CleanWorld plans to resell electricity generated onsite under a Power
Purchase Agreement to the university. It's critical that the system run
without interruption," Crouse said.

"CleanWorld Partners is internationally recognized for its forward-thinking
approach in the renewable-energy market," said Darren Jamison, Capstone
President and Chief Executive Officer. "The company's innovation, paired with
Capstone's clean-and-green technology, provides an unrivaled foundation that
enables companies to meet their zero-waste initiatives."
