A brief description of the on-site renewable electricity generating facilities/devices:
Lincoln Hall Solar PV Array installed in 2011. 234 panel array with peak capacity of 54kW, equivalent to about 2.9% of building’s energy demand. Dashboard: http://live.deckmonitoring.com/?id=psu_lincoln_hall. This is the only source counted in above figure.
“Living Laboratory” project in 2010 on Science Research & Teaching Center’s (SRTC) 3rd floor patio integrates green roof technology with PV at a 4.9 kW peak output. Monitoring of the various functions of green roofs and the output of the solar arrays will test the hypotheses that plants grow better with partial shade and solar panels perform better with a cooler under layer. Dashboard:http://solar.pdx.edu/home/visualizations/
PV Test Facility installed in 2008 at Cramer Hall includes five different types of solar arrays representing different technology and inverters with a 5 kW peak output. Annually, this could generate about 5,000 kWh, which is estimated to save $330 in annual utility costs. Dashboard: http://solar.pdx.edu/home/visualizations/
Campus Recreation Center uses exercise machines use ReRev technology to generate electricity for the building.
Millar Library recently installed PV array, but it is not yet operational. The array has a peak capacity of 86kW.

Unbundled renewable energy products
| kWh | MMBtu | |
| Purchased RECs, GOs, I-RECs or equivalent unbundled renewable energy products certified by a third party | 220,000 Kilowatt-hours | 750.64 MMBtu |
A brief description of the unbundled renewable energy products:
220 MWh of Green-e RECs were purchased to cover a portion of expected electricity use at the Karl Miller Center. The amount was determined based on LEED credit requirements for Green Power. These RECs were purchased through Renewable Choice Energy, now part of Schneider Electric, for both Fiscal Years 2019 and 2020.
