OP-6: Clean and Renewable Energy
|0.70 / 4.00||
Total energy consumption (all sources, excluding transportation fuels), performance year :
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:
A brief description of on-site renewable electricity generating devices :
Cornell owns and operates two hydroelectric generators. The turbine manufacturer is Ossberger and the units are rated at 712 kw and 997 kw. In addition, there are multiple campus building with roof-top PV. FY18 generation 101,177 kWh
Snee, Klarman, HEB,Day Hall, Campus Store
Non-electric renewable energy generated on-site, performance year:
A brief description of on-site renewable non-electric energy devices:
Cornell also has a heat exchange facility (Lake Source Cooling) to produce up to 20,000 peak tons of chilled water for campus. It generates renewable cooling by exchange heat to cold water from deep in Cayuga Lake saving 86% of the energy of conventional cooling (~25 million kWhr/year, about 10% of total campus electricity usage).
Cornell has installed two solar hydronic hot water systems. The systems use the solar energy to heat water in evacuated tube solar collectors. The systems are designed to offset the need for fossil fuels to provide a portion of the heating and hot water needs of two campus facilities (23 total panels with 30 tubes each). Each tube is rated at 1,000 btu/day at peak summer solar insolation.
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:
A brief description of off-site, institution-catalyzed, renewable electricity generating devices:
Cornell has seven PV arrays located on Cornell property. The generation is credited to the Ithaca campus via remote net metering by NYSEG. Cornell was responsible for catalyzing these projects.
The generation is purchased via Power Purchase Agreements.
Cornell owns the environmental attributes and officially retires those attributes via the New York state attribute tracking system. The retirements are approved & document in RGGI.
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:
A brief description of the RECs, GOs and/or similar renewable energy products, including contract timeframes:
