WASHINGTON (Sputnik) — The contract covers a period of more than 43 years and is expected to be completed by September 2039, the Defense Department said.
"Johnson Controls Government Systems Milwaukee, Wisconsin, is being awarded $186 million… contract for energy improvements at Naval Station Norfolk… for the design and installation of cogeneration systems," the announcement stated on Wednesday.
Cogeneration systems deliver two forms of energy — electricity, plus hot water or chilled water — from a single fuel source using the free "waste" heat in addition to the electricity produced to achieve overall operating efficiencies much higher than a conventional system.
Cogeneration systems are estimated to be able to reduce the greenhouse gas emissions, normally associated with electricity and hot water production, by as much as 50 percent, according to published reports.
