UC San Diego operates a cogeneration facility that supplies approximately 88% of the campus's electricity. In addition to saving approximately $8 million per year in purchased utilities costs, cogeneration reduces:
- Energy losses due to transmission and distribution of electricity over the statewide electrical grid
- Reliance on out-of-state coal-burning power generation
- Regional congestion on SDGE's grid system.
The 27 MW combined cooling heat and power plant and 3.4-million-gallon thermal storage system are part of UCSD's state-of-the-art microgrid.
