|0.08 / 7.00||
Option 1: 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 :
Option 2: Non-electric renewable energy generated:
Option 3: 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 :
Option 4: Total RECs and other similar renewable energy products that the institution purchased during the performance year that are Green-e certified or meet the Green-e standard's technical requirements and are third party verified:
Option 5: Total electricity generated with cogeneration technology using non-renewable fuel sources :
Total energy consumed during the performance year :
A brief description of on-site renewable electricity generating devices :
Our multi-modal transportation center is powered by 960 photovoltaic (PV) panels. Each PV panel has an output of 215 watts, which is a total 206,400 watts for the system. The surplus power from the panels is tied back into is tied back into UNI's electrical grid for use by other campus buildings.
A brief description of on-site renewable non-electric energy devices:
A brief description of off-site, institution-catalyzed, renewable electricity generating devices:
A brief description of RECs or other similar renewable energy products purchased during the previous year:
A brief description of cogeneration technologies deployed:
Located on the west edge of campus, the UNI Power Plant generates steam and electrical power providing energy for lighting, heating and cooling systems for main campus buildings.
This co-generation plant uses four boilers with a total steam capacity of 345,000 pounds/hour to annually produce 689 million pounds of steam. The steam is used on campus for building heat, domestic hot water heating, cooking in food services, and making chilled water for cooling via steam absorption chillers. The plant is staffed 24 hours a day, 365 days a year.
Campus used 59.2 million kilowatt-hours of electricity per year. The power plant produces 41% of the electricity with a 7.5 mega-watt extraction turbine. The remaining 59% electrical usage is purchased from the local utility.
Steam and electricity are distributed from the plant to campus via tunnels, underground piping systems and underground conduit systems.
Due to turbine being down, the co-generation plant was offline for roughly half of the year.
