Total energy consumption (all sources, excluding transportation fuels), performance year :
1644820 MMBtu

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:
0 MMBtu

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

PV solar consists of 88 systems across ASUs four campuses and Research Park, and has a capacity of 24.1 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.


Non-electric renewable energy generated on-site, performance year:
8350 MMBtu

A brief description of on-site renewable non-electric energy devices:

-67 MMBtu Solar Thermal at Nursing & Healthcare Innovation
-7,714 MMBtu Solar Thermal at Sun Devil Fitness Center Tempe
- 75 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


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:
110890 MMBtu

A brief description of off-site, institution-catalyzed, renewable electricity generating devices:

The ASU Red Rock Solar Project is a collaboration between ASU and APS in which APS constructed and operates a solar energy generating facility at Red Rock, Arizona. Beginning January 2017, ASU has committed to purchase 65,000 MWh per year of solar generated electricity from APS. The agreement between APS and ASU will allow for the transfer of the environmental attributes to ASU. This transfer is currently being finalized. Only half of the generation was accounted for in this submission due to university fiscal year data collection and reporting.


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:
141257 MMBtu

A brief description of the RECs, GOs and/or similar renewable energy products, including contract timeframes:

Some on-site solar RECs have been transferred.

ASU has purchased RECs for FY15 that were delivered in 2016.

ASU has also purchased RECs for FY16 that were delivered in 2017. The amount purchased is sufficient to offset the estimated amount of renewable energy certificates sold related to on-site solar generation during FY16.

ASU has purchased RECs for FY17 that will be delivered in 2018. The amount purchased is sufficient to offset the estimated amount of renewable energy certificates sold related to on-site solar generation during FY16.
