North Carolina State University has signed a $56m contract with Ameresco, an energy efficiency and renewable energy solutions company, to implement a number of energy conservation measures at two campus central utility plants.

The project focuses on improving the reliability and efficiency of campus central steam and chilled water generation.

This energy saving performance contract will add cogeneration equipment that will provide 11MW of electric generation and 100,000lbs/hr of steam generation at one facility.

The other facility is designed to receive upgrades that will provide for another 300,000lbs/hr of new more efficient steam generating capacity.

Implementation of all the planned energy conservation measures at the two central utility plants is expected to provide the university $6.5m in average annual energy savings.
