This project adds to NYC Transit's use of clean energy power sources.
In 1996 NYPA installed a 300-kW roof-mounted solar power array at the
Gun Hill bus depot in the Bronx. During warm weather months, the solar
array supplies 15 percent of this bus depots' electrical needs. NYC Transit
has been using solar energy to provide power to the Maspeth Warehouse
Facility in Queens and the Jackie Gleason Bus Depot in Brooklyn since the
late 1990s.
NYC Transit also has a 100-kW solar canopy at the reconstructed
Stillwell Avenue Terminal in Coney Island. NYC Transit became a full sig-
natory of the International Association of Public Transportation's (UITP)
charter on Sustainable Development in Mobility in 2004 and was the first
public transit agency in the world to attain international certification for
environmental management (ISO 14001). The New York Power Author-
ity is a major national proponent of clean distributed energy technologies
with 2.4 megawatts of installed capacity. It has installed 11 fuel cells in the
New York City metropolitan region including eight at wastewater treat-
ment plants, operated by NYC, where the units generate power using as
fuel the gases produced through the wastewater cleansing process.
A cogeneration unit may fall under the provisions of one or more
environmental and regulatory acts that cover power generation and in-
dustrial installations. Most systems of 5 to 100 kilowatts are likely to be
exempt from environmental regulations except local building and zon-
ing codes. Larger systems with a capacity in the area of some 500 to 2,500
kilowatts must comply with emission limits for five pollutants: nitrogen
oxides, sulfur dioxide, small suspended particulates in the air, carbon
monoxide and the photochemical oxidants found in smog. State regula-
tions may also apply to small cogeneration systems. Regulations that af-
fect small cogeneration systems include those governing noise pollution,
water discharge and solid waste disposal.
Systems with a generating capacity of 75,000 kilowatts or less are ex-
empt from most federal regulations governing power generation. Systems
larger than about 75,000 kilowatts, or that sell 25,000 kilowatts or 1/3 of
their generating capacity must comply with the Environmental Protection
Agency's Stationary Sources Performance Standards for Electric Utility
Steam Generating Units.
