Total energy consumption, performance year:
1,957,400.56 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) 65,000,004 Kilowatt-hours 221,780.01 MMBtu
Electricity from on-site, clean and renewable sources (rights retained/retired) 0 Kilowatt-hours 0 MMBtu

A brief description of the certified/verified sources of clean and renewable electricity:
The ASU Red Rock Solar Project is a collaboration between ASU and Arizona Public Service. APS agreed to construct and operate roughly 29 MWdc of solar energy generating capacity for ASU at its Red Rock site near Casa Grande, Arizona. In return, ASU agreed to purchase 65,000 megawatt hours of solar energy per year for 20 years.


A brief description of the on-site renewable electricity generating facilities/devices:
PV solar consists of 90 systems across ASU's four campuses and Research Park and has a capacity of 24.25 MWdc. The systems are either roof mounted, ground-mounted, parasols, and on top of parking garages or over parking lots. RECs are sold and repurchased as outlined below.

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

A brief description of the certified/verified sources of clean and renewable thermal energy:
Solar thermal systems at ASU for domestic hot water:
- 67 MMBtu Solar Thermal at Nursing & Healthcare Innovation
- 6,684 MMBtu Solar Thermal at Sun Devil Fitness Center Tempe
- 54.34 MMBtu Solar Thermal at Sun Devil Fitness Center Tempe
- 128 MMBtu Solar Thermal at Sun Devil Fitness Complex West
- 365 MMBtu at Solar Thermal Sun Devil Fitness Complex Polytechnic

Unbundled renewable energy products (report kWh):
kWh MMBtu
Purchased RECs, GOs, I-RECs or equivalent unbundled renewable energy products certified by a third party 227,135,945 Kilowatt-hours 774,987.84 MMBtu

A brief description of the unbundled renewable energy products:
ASU has purchased Green-e certified RECs from multiple vendors to match both its imported electricity use and the on-site solar PV generation that does not retain its RECs.
