Studies: Microturbines - Boeing
Protect data network and phone equipment from grid outages using an onsite power
solution that delivers low maintenance and minimal environmental impact in a compact
package with little noise and no vibration.
The Capstone MicroTurbine system keeps telecom and data devices running around-the-clock
with significant advantages over conventional technologies.
- Ensures non-stop
data network/telecom operation via 24x7 onsite power generation
- Much smaller
footprint and sound signature than battery/genset installations
- Minimal scheduled
maintenance compared to battery/genset combinations
- No hazardous
liquids or materials, unlike battery/genset installation
- No special
emissions permitting thanks to <9 ppm NOx emissions fueled by natural gas
- Low forecasted
O&M costs due to air-cooled/air-lubricated design that has just one moving

20 kW power for six hours duration. UPS batteries and genset engines were the
conventional choice, but not the best fit with the company's requirements. Genset
noise, emissions and vibration would be difficult to mitigate.
Kind of Jet: The Capstone MicroTurbine
Opting for a different power solution, Boeing chose the Capstone MicroTurbine.
Based on scaled-down jet technology, the Capstone MicroTurbine's one moving part
is air-cooled and air-lubricated, eliminating the need for liquid lubricants,
antifreeze, other hazardous fluids, or even water. The Capstone solution inherently
results in little scheduled maintenance. It is designed to run 8,000 hours (nearly
one year nonstop) between recommended minor inspections and cleaning/replacement
of filters. Adding to its ease of operation and end-user transparency, the Capstone
MicroTurbine features a compact footprint, relatively low noise and no vibration,
which greatly expand siting options.
Associates/MGE UPS Systems installed a Capstone C30 in a pre-existing concrete
enclosure near the building's loading dock, demonstrating Capstone's ability to
integrate easily with available equipment and layouts. MGE's service personnel
started up the system and placed it on line. The C30 runs on natural gas and sends
electric power 24x7 to the data network and telecom equipment consisting of nine
switches, two routers and approximately 1,000 phones. The data/telecom system
utilizes dual power inputs: one from the microturbine and one from the grid. In
the event of a grid power outage, the C30 ensures uninterrupted service. If the
microturbine goes offline, the utility grid is the backup source. Boeing required
no special emissions or hazardous materials permitting thanks to Capstone's ultra-low
emissions and air-cooled/air-bearing design.
of Capstone MicroTurbines in Power Quality/Reliability Applications
- The Capstone
MicroTurbine is designed for continuous operation. This, plus an emissions profile
far below any permitting restrictions, means runtime is unlimited.
- In many regions,
Capstone MicroTurbines generate power at a cost lower than that of utility rates.
demand reduction payback is the opportunity for cogeneration (using the exhaust
heat for heating, drying or heat-driven absorption chilling).
of Energy Storage (Batteries)
take up valuable floor space, require energy-intensive temperature regulation,
contain environmentally hazardous materials, and are costly to maintain and replace.
- A Capstone
MicroTurbine UPS reduces storage or rectifier battery capacity to 5 minutes, with
the grid as the last backup source.
of Operating and Maintenance Costs
engines require hazardous material permits for the storage and disposal of liquid
coolants and lubricants, as well as change out activities.
air-lubricated Capstone MicroTurbines use no hazardous materials.
- Capstone MicroTurbines
have very minor recommended maintenance intervals every 8,000 hours and recommended
overhaul at 40,000 hours.
- Compared to
other generators, Capstone MicroTurbines are lighter, have a smallerfootprint,
produce less noise and are vibration-free.
