Total energy consumption, performance year:
404,033.73 MMBtu

Clean and renewable electricity (report kilowatt-hours):
kWh MMBtu
Imported electricity from certified/verified clean and renewable sources (i.e., bundled green power purchases) 0 Kilowatt-hours 0 MMBtu
Electricity from on-site, clean and renewable sources (rights retained/retired) 25,965 Kilowatt-hours 88.59 MMBtu

A brief description of the certified/verified sources of clean and renewable electricity:


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

A nominal 24.7 kW photovoltaic array is installed on the roof of the Micron Business and Economics Building. The array consists of (76) nominal 325W panels oriented roughly east and west, tilted approximately 10 degrees up from horizontal.

Clean and renewable thermal energy (report MMBtu):
Clean and renewable stationary fuels used on-site to generate thermal energy 0 MMBtu
Imported steam, hot water, and/or chilled water from certified/verified clean and renewable sources 6,509 MMBtu

A brief description of the clean and renewable stationary fuels:


A brief description of the certified/verified sources of clean and renewable thermal energy:

The University contracts with the City of Boise to use district geothermal water as a heat source for eleven campus buildings. The City administers the nation’s largest geothermal district heating system. Geothermal water supplies heat to building hydronic loops via plate and frame heat exchangers. Generally the high-temperature resource is used directly, but one building has a “cascade” arrangement where low-temperature return water from an adjacent building supplies a water-source heat pump loop. Geothermal water is furnished as an interruptible resource so backup heat is required for each building.

Unbundled renewable energy products (report kWh):
kWh MMBtu
Purchased RECs, GOs, I-RECs or equivalent unbundled renewable energy products certified by a third party 0 Kilowatt-hours 0 MMBtu

A brief description of other sources of electricity not specified above:

Idaho Power purchases a fraction of its electricity from other utilities on the wholesale market but does not disclose the makeup of this electricity on its website. Additionally, note that some of the renewables reported in this table have had their RECs sold to others by Idaho Power.

Energy used for heating buildings, by source::
Percentage of total energy used to heat buildings (0-100)
Biomass 0
Coal 0
Electricity 0
Fuel oil 0
Geothermal 3.40
Natural gas 96.60
Other (please specify and explain below) 0

A brief description of other sources of building heating not specified above:

Note that some university-owned buildings have electric heating. A comprehensive accounting of which buildings are electrically heated does not exist at this time. The magnitude of electric heating energy is believed to be small relative to the University’s natural gas heating energy, and has been excluded from the table above.
