Total energy consumption (all sources, excluding transportation fuels), performance year :
1,460,903 MMBtu

Total clean and renewable electricity generated on site during the performance year and for which the institution retains or has retired the associated environmental attributes:
21,512 MMBtu

A brief description of on-site renewable electricity generating devices :

UCI receives clean and renewable energy from multiple on-site photovoltaic (PV) projects on the UCI campus. A 109 kW ground-mounted concentrated photovoltaic array (CPV array), a 1,005 kW building rooftop mounted PV array, a 48 kW mounted PV array with battery storage on the Anteater Parking Structure, and 2,569 kW on three other parking structures.


Non-electric renewable energy generated on-site, performance year:
0 MMBtu

A brief description of on-site renewable non-electric energy devices:

Recovered heat from our combustion turbine power plant generates high-temperature water, which provides heating to the campus. In addition to heating the campus, recovered heat is also used in a steam turbine chiller to produce chilled water to cool the campus buildings. This is more efficient than producing electricity to in turn run an electric chiller.


Total clean and renewable electricity generated by off-site projects that the institution catalyzed and for which the institution retains or has retired the associated environmental attributes, performance year:
5,987 MMBtu

A brief description of off-site, institution-catalyzed, renewable electricity generating devices:

The University of California Office of the President formed the UCOP Energy Services Unit (ESU). The ESU is a CalISO registered Energy Service Provider. The campus is on direct access and purchases generation from the UCOP ESU. The ESU commissioned the Five Points Solar Park, LLC a 70MW solar plant that the UC system retains the REC's to. The reported REC's are UCI's share of that systems renewable energy.


Total third-party certified RECs, GOs and/or similar renewable energy products (including renewable electricity purchased through a utility-provided certified green power option) purchased during the performance year:
3,803 MMBtu

A brief description of the RECs, GOs and/or similar renewable energy products, including contract timeframes:

Third-party Renewable Energy Credits (RECs) that have been purchased by the campus are certified through the Green-e program.

A brief description of other sources of building heating not specified above:

UC Irvine operates a combined heat and power (CHP) plant supplying clean energy to the campus and providing a model of clean and efficient energy delivered through a campus microgrid. The energy provided from the heat recovered from the CHP turbine (407,314 MMBtu in 2016) is delivered to provide heating to the campus as part of UCI’s district thermal energy loop. This recovered heat displaces approximately 512,344 MMBtu of natural gas which would have otherwise been burned to supply heat to the campus with a conventional boiler plant.

Clean energy provided through CHP, such as occurs in UCI’s microgrid, is recognized by the California Energy Commission, US Environmental Protection Agency, and US Department of Energy as a key clean and renewable energy strategy required to achieve state greenhouse gas emission limits and federal actions to address carbon pollution. Consistent with this strategy the Scoping Plan for the California Global Warming Solutions Act (AB 32) requires installation of 4,000 MW of additional CHP in California by 2020 and the California Clean Energy Jobs Plan calls for 6,500 MW of CHP by 2030. In addition, US EPA and DOE clean energy strategy identifies a 50% increase in CHP by 2020.


Percentage of total energy consumption from clean and renewable sources:

UCI's campus-wide deployment of renewable energy systems provides distributed generation within the campus microgrid and supports the campus' leading-edge research in clean energy and microgrid/smart grid integration. This includes 1,005 kW of building rooftop photovoltaic (PV) panels, 109 kW of concentrated photovoltaic (CPV) ground-mounted panels, and 2,617 kW of PV panels mounted on campus parking structures. In keeping with UCI's role as a living laboratory for sustainability, these systems provide a test bed for renewable energy technology and smart grid integration of renewable energy systems onto the campus microgrid, supporting multiple collaborative research projects involving UCI faculty, staff, and students.

UC Irvine quadrupled the amount of green power it generates on-site with the addition of solar photovoltaic canopies on three campus parking structure roofs. More than 11,700 newly placed solar panels generate up to 2.6 megawatts of power, the amount needed to meet the electrical needs of 1,600 homes. UCI is installed the solar PV systems under a 25-year power purchase agreement with a subsidiary of NextEra Energy Resources LLC.
