Cornell Combined Heat-and-Power Project (CCHPP)
The Cornell Combined Heat-and-Power Project (CCHPP) was the result of extensive study and development. Located south of the existing heating plant, the project integrated a 30 MW cogeneration system into existing boiler house facilities to provide energy and fuel flexible security while allowing the retirement of coal-fired assets and a liquid fuel conversion from No. 6 to No. 2 oil.
The plant incorporates two dual-fuel 15 MW dry low-NOx Solar Turbines Titan 130 gas turbine generators (GTG), two dual-pressure duct-fired Rentech heat recovery steam turbine generators (GTG) with SCR and CO emissions control. A new 3.2-mile high-pressure gas line was designed and constructed so that on-site gas compression was not required.
A new building to contain equipment was designed and integrated into the area’s steep topography. Renewals and upgrades to the existing 115-13.2 kV substation, along with a third transformer, accept the CCHPP output and further increase reliability. These upgrade were installed without service interruption to the campus.
