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) 10,430 Kilowatt-hours 35.59 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:
Although UMass generated almost 6 million kwh of on-site renewable electricity on the campus in FY22, the only project for which the institution retains or has retired the associated environmental attributes for is the 16kW Deerfield farm solar PV (10,430 kwh=35 MMBTU).

It should be noted that under the Massachusetts state SMART program, only utility companies can retain and claim the renewable energy attributes of renewable electricity generating units, therefore the only way for UMass to claim points for this section of the credit would be to purchase replacement REC's in the form of utility-provided green power purchasing options.

Clean and renewable thermal energy (report MMBtu):

Clean and renewable stationary fuels used on-site to generate thermal energy 89 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:
None.

A brief description of the certified/verified sources of clean and renewable thermal energy:
In FY16, UMass Amherst installed a 113 kW solar thermal system on the CHP. 113 kW (387kbtu/hr) solar thermal system at the CHP (26,155 kwh=89 MMBTU)

Unbundled renewable energy products (report kWh):
kWh MMBtu
Purchased RECs, GOs, I-RECs or equivalent unbundled renewable energy products certified by a third party 8,246,203.44 Kilowatt-hours 28,136.05 MMBtu

A brief description of the unbundled renewable energy products:
MA Class I RECs equivalent to 24% of campus grid electricity usage are retired on UMass’ behalf by the electricity suppliers that serve UMass' campus electricity imports, to meet state Renewable Portfolio Standard and Clean Energy Standard goals.

Total clean and renewable energy generated or purchased:
28,260.63 MMBtu

Data source(s) and notes about the submission:
UMass Amherst has significantly increased the on-site renewable energy generation over the past decade.
Prior to FY15, UMass installed ground source heat pumps in the Police Station and the International Programs Building (formerly Research Admin)
In FY15 the campus had 16 kW of solar PV energy from the Deerfield Farm.
In FY16, UMass Amherst installed a 336 kW solar PV canopy system.
In FY17, UMass Amherst installed a 5.5 MW solar PV system on 7 different sites (2 parking canopies and 5 rooftops).
In FY18, UMass installed ground source heat pumps in Crotty Hall.
In FY22, UMass installed two more large PV canopy systems on Lots 21/22 and Lot 49 with a battery system fully charged by the solar generation.
