Fort Bragg saves 1.8 million annually with efficient
Minneapolis, MN— Honeywell
announced the completion of a prototype cooling, heating and power
(CHP) generation system at Fort Bragg in Fayetteville, North Carolina
designed to improve energy infrastructure, reduce energy consumption
and increase energy security.
Initiated by the Directorate
of Public Works (DPW) at Fort Bragg and developed with the Department
of Energy (DOE) through Oak Ridge National Laboratory, the new
system uses energy recycling to achieve an estimated 70 percent
overall energy efficiency — a considerable improvement over
the 35 to 40 percent efficiency typical with centrally generated
electricity sources. The installation represents a significant
advance in energy management and is projected to reduce Fort Bragg
energy costs by $1.8 million per year.
The prototype is the latest phase
in an energy partnership between Honeywell and the Fort Bragg
DPW, which is responsible for almost 30 million square feet of
facilities at the 84-year-old Army post. Formed under an Energy
Savings Performance Contract (ESPC), the partnership has cut total
energy costs at Fort Bragg by more than 25 percent over the last
seven years. ESPCs allow the federal government to use private
financing to upgrade buildings and make them more energy efficient.
Contractors like Honeywell are paid from the cost savings and
are required to guarantee that the government will save more money
than it spends.
“This has been an extremely
productive relationship,” said Joe Puishys, president of
Honeywell Building Solutions. “Together, the U.S. Army and
Honeywell have saved more than $57 million at Fort Bragg to date.
And over the entire course of the ESPC, Fort Bragg will be able
to make $66 million in capital investments at no additional operating
cost to the government and taxpayers.”
The new, $11-million CHP system
is an integrated system built around a five-megawatt gas turbine
generator coupled with an innovative heat recovery steam generator
and absorption chiller. Waste heat produced during combustion
of natural gas fuel, which drives the turbine generator, is directed
to either the heat recovery steam generator or absorption chiller.
The steam generator uses waste heat to produce steam for heating
and hot water, and the chiller converts the waste heat to chilled
water used for air conditioning. The ultra-efficient design is
the first of its kind.
