Project Profile: Lincoln Medical and Mental
In upgrading Lincoln Medical and Mental Health Center’s
outmoded central chiller and boiler plant system, the Power Authority’s
foremost concern was avoiding disruptions to the 24-hour operation of
one of New York City’s busiest hospitals.
The center offers vital services to the people of the
Bronx, within one million square feet of facilities, including more than
600 beds, a trauma center and a constantly busy emergency room.
A NYPA analysis revealed that the hospital’s aging
chillers and boilers required relatively dirty No. 6 oil as secondary
fuel and utilized a refrigerant that was in general use when the complex
was built in 1974 but is not permissible today. Lincoln faced the
increasingly strict requirements of the Federal Clean Air Act. In
addition, the poor efficiency of the chillers and boilers increased fuel
costs, and their quarter-century-old status dictated high and growing
NYPA’s Energy Services department installed new
high-efficiency electric chillers and dual-fueled (natural gas and
cleaner No. 2 fuel oil) boilers, and an emergency diesel generator to
help meet Lincoln’s critical loads in the event of a power failure.
Emissions were dramatically reduced, and the new chillers utilized
During the yearlong project, the four-unit, 5,400-ton
capacity chiller plant was brought in through an opening in a second
floor wall, and each of three boilers was positioned in a room adjacent
to the emergency room. These efforts were carefully planned and
coordinated, resulting in no interruption to the hospital’s normal daily
Lincoln will save more than $625,000 a year in energy
and maintenance costs from the $6.9 million project. NYPA provided
financing to the hospital through its long-term energy partnership
agreement with the City of New York.
