University of California, San Diego
OP-6: Clean and Renewable Energy

Our campus has a variety of certified/verified sources of clean and renewable electricity. These include UC Clean Power Program direct access power purchasing options, power purchase agreements (PPAs) for electricity generated on and off site, and equivalent products that bundle physical electricity with the right to claim its renewable energy attributes.
NOTE: THE UC CLEAN POWER PROGRAM HAS ONLY A SINGLE PORTFOLIO THEREFORE SOME OF THE IMPORTED RENEWABLE ELECTRICITY IS USED TO MEET RENEWABLE PORTFOLIO STANDARDS REQUIREMENTS.

UC San Diego has 3.1 megawatts of solar photovoltaic generating capacity installed at a combination of on-campus and off-campus sites, including the Hillcrest Medical Center, Nimitz Marine Facility, Elliott Field Station and the Trade St. Shipping & Receiving Center. Approximately 2 MWs are directly owned by the University, while 1 MW is owned by a third party with both the electricity and the associated renewable energy credits (RECs) being purchased by the University through a Power Purchase Agreement (PPA). The existing arrays include a combination of roof mount, parking canopy and ground mount systems.

The planned renewable energy strategy builds on the existing deployment of PV arrays and sets realistic targets for future campus deployment of renewable energy resources, including:

- Roof mounted PV arrays: Install an additional 3.4 MWs of rooftop solar on existing and new construction projects.

- Covered parking PV arrays: Install an additional 2.6 MWs of carport PV canopies on existing and new parking structures.

- Solar thermal hot water: Where appropriate utilize solar thermal to assist in generating high temperature hot water for domestic hot water needs.

In addition to the above, the campus will consider the following for possible inclusion in the renewable energy strategy:

- Anaerobic digestion: Construction of a plant to process all organic food waste and generate biogas for on-campus use or direct energy generation. The potential to bring in food waste from the surrounding area to supplement campus supply will also be investigated.

- Ground mount photovoltaic arrays: Expansion of the existing ground mount solar array at Elliott Field Station. Initial estimates are that up to a 4 MW system could be constructed, which would allow for lower costs achieved through the economies of scale from building a single large system. The renewable power generated could be credited to the campus either through the RES-BCT tariff or the UC Energy Service Unit's Direct Access program.

- Satellite power generation: Investment in small-scale power provision, in the form of biomass CHP and a new biogas-powered fuel cell, which would not only increase the campus renewable energy generation but would also improve campus resilience through diversity of fuel and method of power provision. It also allows the university to become acquainted with developing technology, especially in the area of biomass energy generation.

Two outdoor Olympic-sized swimming pools are heated by solar thermal systems. UCSD also has on-roof solar.

Green-e certified RECs were purchased in 2019 for 13.5% of the campus’s total purchased electricity. The RECs are composed primarily of biomass, wind, and solar PV.

"Other" is landfill gas, digestor gas, or unspecified by our power supplier.

For total energy consumption performance year: note that this includes the Main Campus in La Jolla (including East Campus), but NOT the Hillcrest campus or other off-site facilities. This sum includes gas input for the onsite cogeneration plant (since UC San Diego owns the plant), electricity output of the fuel cell (since UC San Diego purchases the electricity from a third party through a power purchase agreement), electricity purchased from the UC Office of the President and San Diego Gas & Electric, electricity generated by onsite solar panels, and gas purchased from the utility.
