Total energy consumption, performance year:
Clean and renewable electricity (report kilowatt-hours):
| kWh | MMBtu | |
| Imported electricity from certified/verified clean and renewable sources (i.e., bundled green power purchases) | 4,754,000 Kilowatt-hours | 16,220.65 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:
Sac State's renewable electricity sources include solar purchased through multiple PPA's, Greenergy blocks through SMUD and Hydro-electricity through the Western Area Power Authority.
A brief description of the on-site renewable electricity generating facilities/devices:
Sac State installed a Photovoltaic (PV) system with a new car port located behind the Facilities Management building during the 2001-02 time frame. The car port is 108 Ft. long and 18 Ft. wide. The installed system size is 6.5 kW. This system is still in operation today.
During the same time period as the car port installation, we installed (11) 110W PV powered parking lot lights and (11) 195W powered parking lot lights in lot-10, in late 2001. This system is still in operation today.
Sac State entered into a Power Purchase Agreement (PPA) for Photovoltaics (PV), at two locations on campus for renewable energy produced at a fixed rate of $0.1086/kWh for a 20 year duration. The two PV solar panel projects totaling a maximum capacity of approximately 500 kW. They were both roof mounted, PV systems located on the Library (272 kW) and The WELL (228 kW). Both projects were completed in March 2013 using a Power Purchase Agreements approach. Currently, The WELL system produces about 16% of the total electricity required for the building. The Library South system produces about 40% of the total electricity required for the building.
Clean and renewable thermal energy (report MMBtu):
| MMBtu | |
| Clean and renewable stationary fuels used on-site to generate thermal energy | 846.28 MMBtu |
| Imported steam, hot water, and/or chilled water from certified/verified clean and renewable sources | 0 MMBtu |
A brief description of the clean and renewable stationary fuels:
Sac State entered into a Power Purchase Agreement (PPA) for Solar Hot Water back in 1986. These systems are still operational to date and are still providing clean renewable hot water which is generated on site. The Solar Hot Water systems are located on the roof of Riverfront Center, Yosemite Hall North and South, and the Pool at Yosemite Hall.
American River Courtyard is one of our housing developments built in 2009 on campus. It also has a Solar Hot Water system.
All these systems play a critical part in our operational ability to reduce GHG emissions.
A brief description of the certified/verified sources of clean and renewable thermal energy:
The campus has 3 thermal hot water production systems on site purchased through a PPA.
Unbundled renewable energy products (report kWh):
| kWh | MMBtu | |
| Purchased RECs, GOs, I-RECs or equivalent unbundled renewable energy products certified by a third party | 1,000 Kilowatt-hours | 3.41 MMBtu |
A brief description of the unbundled renewable energy products:
Sac State participates in SMUD’s Greenergy program. Sac State purchases a small amount of SMUD’s Greenergy product which is certified Green-e, and SMUD keeps the Renewable Energy Credits for this purchased energy.
