What is a Capstone turbine?
• In layman's terms, “A miniature jet engine that runs at speeds up to 96,000 rpm and generates electricity and heat.
• Electrical power output: 30 kW to 5MW range
• Highly Reliable
• Ultra low emissions
• Multiple fuels; natural gas, propane, diesel, biodiesel, methane/biomass
• Simple/cost effective design
• Low maintenance

Microturbines vs Piston Engines
Capstone Microturbines Traditional Piston Engines
Ultra low emissions Local air permits and exhaust cleanup required
Low maintenance – Six hours per year High maintenance – Oil changes, Coolant, Spark plugs
On board digital electronics External controls without power electronics
Integrated utility protection & synchronizing Requires external relays & control equipment
Lightweight & small footprint More than twice the weight & footprint

CCHP Case Study:Ronald Reagan Presidential Library and Museum The Issues:
– Overcome potential power supply issues and rolling blackouts
– Keep exhibit building containing retired Air Force One jet cool, comfortable, and well lit
The Solution:– 16 C60 microturbines running on clean-
burning natural gas supply 95% of the facility’s electricity
– Three 129-ton direct exhaust-fired absorption chillers create 387 tons of refrigeration for cooling
– Exhaust from the microturbines provide hot water to heat the pavilion
Savings:– Over $300,000 in annual operating
costs– $823,156 incentive reduced installation
cost 30%

Hybrid Electric Vehicle Case Study:DesignLine / Hybrid Buses
The Issues:• Run low emission vehicles in
densely populated areas• Increase fleet efficiency• Reduce maintenance• Improve reliability
The Solution:• The buses' Capstone turbine generates electricity to
charge batteries, which run electric motors. The batteries are charged overnight and the turbine system recharges them when operating.
• The vehicles are fitted with remote monitoring which means Designline engineers can talk to the on-board computers monitoring performance and carry out diagnostic checking.

Secure Power Case Study:Boeing Data / Telecom System
The Issues:– Protect data and phone networks
and equipment from grid outages– Minimize noise and vibration– Allow minimal environmental impact
The Solution:– A Capstone C30 microturbine was installed in a pre-
existing enclosure near the building’s loading dock– The natural gas powered microturbine provides
electric power 24x7 to the network and equipment– The microturbine ensures uninterrupted service in the
event of a grid power outage– The Capstone technology was preferred over UPS
batteries and genset engines due to their noise, emissions and vibrations
The Capstone C30 demonstrates its small footprint on site at Boeing.
Installation was simple, with the turbine placed in an existing enclosure.
