Total energy consumption, performance year:
298,390.29 MMBtu

Clean and renewable electricity (report kilowatt-hours):
kWh MMBtu
Imported electricity from certified/verified clean and renewable sources (i.e., bundled green power purchases) 6,199,716.50 Kilowatt-hours 21,153.43 MMBtu
Electricity from on-site, clean and renewable sources (rights retained/retired) 4,178 Kilowatt-hours 14.26 MMBtu

A brief description of the certified/verified sources of clean and renewable electricity:

According to Xcel Energy, the University's electric utility provider, the "Certified Renewable Percentage" of electricity provided was 23.2% in 2019. Xcel Energy's website states:
"In previous years, we only retired enough Renewable Energy Credits (RECs) annually to meet Minnesota’s Renewable Energy Standard, which requires that 25% of our electricity come from renewable sources. But today, we retire RECs to cover the entire renewable energy portion of the electricity that we deliver to you. That means you can take full credit for our renewables and claim Certified Renewable Percentage with confidence that it’s not being claimed by anyone else."

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

The university currently has three rooftop solar arrays:
1) Solar Array: 40kW Anderson Student Center
2) Solar Array: 3.5kW Brady Hall
3) Solar Array: 48kW McCarthy Gym

The McCarthy Gym array is part of the microgrid research facility and it is currently operating in "island mode."

Additional documentation to support the submission:

The solar array on top of the Anderson Student Center produced 32,900 kWh of electricity in the performance year. However, the utility owns the renewable energy credits from this system for the first ten years of production. Production data for the solar array on top of the student center is available online: http://egauge14405.egaug.es/

Percentage of electricity from different sources is based on Xcel Energy's Saint Paul 2019 Community Energy Report: https://www.xcelenergy.com/staticfiles/xe-responsive/Working%20With%20Us/Community%20Energy%20Reports/City-of-Saint-Paul-2019.xls
