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 cleanburning 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 Capstone C30 demonstrates its small footprint on site at Boeing.
The Solution:
– A Capstone C30 microturbine was installed in a preexisting 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
Installation was simple, with the turbine
placed in an existing enclosure.
