A brief description of cogeneration technologies deployed:
The electric generator, powered by a General Electric LM-1600 gas turbine that burns natural gas or diesel fuel, is a cogeneration facility. What would normally be wasted exhaust heat from the turbine is recovered to heat water and make steam. Through cogeneration and other waste heat recovery, the efficiency of Princeton’s plant rises to the range of 80 percent vs. 25-40 percent for a typical utility energy plant. The cogeneration plant can generate 15 megawatts of electricity, about equal to Princeton’s average electricity needs on a given day. The Princeton turbine was the first of its kind in the world to earn certification to operate on bio-diesel fuel.

Data source(s) and notes about the submission:
The net amount of electricity generated with co-generation technology (241,576 MMBTU) was calculated from the following data: For fiscal year 2011, total net electricity generated using the gas turbine cogeneration system was 67,672,000 kWh; this is the total power generated minus the gas compressor (parasitic) load. The total electricity generated with the backpressure steam turbine cogeneration was 3,130,000 kWh.
