Clean and renewable electricity (report kilowatt-hours):
kWh MMBtu
Imported electricity from certified/verified clean and renewable sources (i.e., bundled green power purchases) 204,829 Kilowatt-hours 698.88 MMBtu
Electricity from on-site, clean and renewable sources (rights retained/retired) 503,882 Kilowatt-hours 1,719.25 MMBtu

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

Windsource is a service provided by Xcel Energy - providing 100% RE. CSU subscribes to Windsource at most of their remote campuses served by Xcel Energy.

From the Xcel website regarding Windsource:
"Windsource is supplied by 100% Colorado wind. With Windsource, the RECs are retired on your behalf, which allows you to say that they are offsetting or using renewable energy." Windsource is a Green-e certified product.

The links to the Xcel website and the Green-e product label is included in the file below.

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

14 solar PV installations across all CSU campuses. An additional 21 systems are in construction adding 4,379 kW to our portfolio. This will add over 6 million kWh/yr in solar electricity generation on-site at CSU.

Clean and renewable thermal energy (report MMBtu):
Clean and renewable stationary fuels used on-site to generate thermal energy 0 MMBtu
Imported steam, hot water, and/or chilled water from certified/verified clean and renewable sources 0 MMBtu

Additional documentation to support the submission:

On January 25, 2017 CSU President, Dr. Tony Frank, signed the Climate Reality Pledge. This will lead to CSU being powered by 100% renewable electricity by 2030. CSU was one of the first universities to take this pledge. In 2018, both local and state-wide utilities serving the majority of CSU campuses made similar pledges for 100% RE; therefore, creating critical alignment for achieving this important goal.

CSU is the site host for a 5,300kW (8.5M kWh/yr) solar plant on the Foothills Campus. When built, in 2008-2009, this was one of the largest associated with a college/university campus. The RECs were sold to the local utility in order to finance the plant. CSU will be able to claim the RECs in 2030.

At the completion of the most recent project, CSU will be host to over 11.2 MW of solar installations on campus. CSU has retained the RECs to approximately 5 MW.
