A brief description of on-site renewable electricity generating 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.
All rights to the REC’s are exclusively and contractually retained by Sac State for the two projects located on the Library and The WELL, however Sac State has not registered with Western Renewable Energy Generation Information System (WREGIS) because of the difficulty in doing so.


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

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 new 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 off-site, institution-catalyzed, renewable electricity generating devices:

N/A


A brief description of the RECs and/or similar 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.
