Electric

UES owns and operates the first 18 cylinder lean-burn natural gas reciprocating engine in North America, providing 5.5 MW of on-site electrical generation and up to 1,000 refrigerated tons of chilled water, offsetting a portion of the campus' 25 MW peak load. On-site power generation currently serves 27% of the main campus electricity with the remaining demand supplied by our utility partner Duke Energy. Duke Energy’s distribution power grid is supplied to the main campus by two 69,000 volt substations. The ability to self-generate electrical power provides both significant cost and environmental benefits to the university.

In FY '16-17, the combined heat and power (CHP) plant has generated 106,298,464 kWh of electricity, 31,801,782 ton hours of chilled water, yielding a fiscal year savings of $24,567,703 ($20,566,979 for electric and $4,000,724 for chilled water), while avoiding 3,502.4 metric tons of carbon dioxide (CO2) and 220 metric tons of sulfur oxide (SOx) being emitted into the atmosphere.
