Total energy consumption (all sources, excluding transportation fuels), performance year :
1,998,889 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:
3,344 MMBtu

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

Washington University has a total solar photovoltaic generating capacity of 765.1 kilowatts (kW) within its scoped GHG boundary, which produces approximately 980,096 kWh of electricity each year. In addition, the university has an additional 1,696 kW of solar capacity installed on distributed sites on university-managed properties outside of the GHG boundary. The data reported above only represents the electricity generated by the 765.1 kW of solar PV within the GHG boundary.


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

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

Hillman Hall and Brauer Hall both have small rooftop solar thermal collectors for domestic hot water heating. Hillman Hall has four collectors and Brauer Hall has two collectors.


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:
0 MMBtu

Missouri is a regulated utility state that does not allow power purchase agreements. The current regulatory environment precludes Washington University from purchasing off-site wind or solar energy, despite favorable pricing for regional wind energy. If legislation passes in Missouri to allow PPAs, Washington University will enthusiastically explore opportunities to shift its electricity from the highly carbon-intensive grid electricity to low- or zero-carbon alternatives. In the interim, we are exploring Virtual Power Purchase Agreement options.
