Total energy consumption (all sources, excluding transportation fuels), performance year :
1,796,906.20 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:
290 MMBtu

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

In the fall semester of 2016, 42 solar thermal panels on top of the new STEM residence building began producing hot water. They are estimated to provide approximately 35% of the building’s heating requirement.

UConn also has two 3.3 kW solar photovoltaic arrays and, although not counted above, a 400 kW natural gas-powered fuel cell on the Depot Campus. The fuel cell prevents the release of approximately 831 metric tons of CO2 per year and, because energy is produced without combustion, emits near zero other harmful air pollutants. Another 8.28 kW solar PV array sits on top of the Reclaimed Water Facility on the Storrs Campus.



The fuel cell and solar array are both on University property, but are owned and maintained by an outside company. UConn purchases the power from this company through a power purchasing agreement (PPA).

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

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

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:
0 MMBtu

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

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:
41,842 MMBtu

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

From 2013-2016, UConn participated in the ConEdison Solutions GREEN Power Program, in which the University agreed to purchase 18 percentage points more renewable energy than what the CT Renewable Portfolio Standard mandates that year. However, in 2015 a REC certificate was given to UConn that showed all, or 100%, of the purchased electricity came from Texas wind, a renewable source of energy. It is assumed that this is the case for 2016 and additionally, starting in 2017, this has been formalized in an updated contract with ConEd where the imported electricity will comprise of 100% renewables. Electricity is only purchased when UConn cannot supply all of the necessary power from our Co-Generation Central Utility Plant.
