501 Pletcher Road, Lewiston, N.Y.
Host: Town of Lewiston Water Pollution Control
Rating: Two 30 kW units
Manufacturer: Capstone Turbine Corporation
Fuel: Anaerobic digester gas
Project Profile: Microturbines Provide Clean
Energy At Lewiston Wastewater Facility
Two 30-kilowatt (kW) microturbines are providing about
one-third of the electricity needed to run the Town of Lewiston Water
Pollution Control Center, a wastewater treatment facility. The
low-profile microturbines are high in symbolic importance as the first
application of this highly efficient, clean energy technology in
municipal use in Western New York.
The twin Capstone Turbine Corp. units will allow the
town to save about $40,000 annually on its electric bill, and, by
replacing a diesel-generator at the end of its useful life, will cut
atmospheric emissions by 90 percent, or about 30 tons each year.
Microturbines are small turbo-generators, fueled by natural gas or, as
at Lewiston, by anaerobic digester gas (ADG). ADG is a "free fuel"
produced through sewage treatment plant operations. A renewable energy
source, it produces both the electricity and, for added energy
efficiency, heat used in the plant's digestion process.
New York Power Authority provided $125,000 for purchase and delivery of
the units, design and engineering services related to demolition of the
old system, installation and technical support. The town did much of the
site preparation and installation work. Funding was augmented with
$100,000 through the state Petroleum Overcharge Restitution fund.
In 2001 Governor George E. Pataki issued an executive
order establishing energy efficiency and renewable energy goals for
state buildings and vehicles, and encouraging local governments to
pursue similar goals. The Lewiston project responds to the governor's
order. NYPA was authorized under the directive to assist municipalities.
