Total energy consumption (electric and non-electric)

Total energy consumption, performance year:

Clean and renewable energy sources

Clean and renewable electricity

Clean and renewable electricity (report kilowatt-hours):
kWh MMBtu
Imported electricity from certified/verified clean and renewable sources (i.e., bundled green power purchases) 631,000 Kilowatt-hours 2,152.97 MMBtu
Electricity from on-site, clean and renewable sources (rights retained/retired) 34,000 Kilowatt-hours 116.01 MMBtu

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

In 2014, Bowdoin began purchasing electricity from a 1.2MW solar photovoltaic PPA that is installed on the Bowdoin campus and provides about 8 percent of Bowdoin's annual electricity usage. The PPA is for a twenty-year term. The College did not purchase the RECs from these solar panels so can not claim any of the environmental benefits, although the College is proud to host this site, which was the largest solar project in the state of Maine at the time it was brought on line. Imported electricity from certified/verified sources come from a major solar project in Farmington, ME (that accounts for the majority of imported electricity), a solar project in Waltham, MA, and three certified hydroelectric projects.


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

Bowdoin has maintained RECs for the solar PV panels on the new Roux Center for the Environment, so can thus claim the full environmental benefit of the system. There are 70 panels which produce 53,000 kWh annually.


Clean and renewable thermal energy

Clean and renewable thermal energy (report MMBtu):
MMBtu
Clean and renewable stationary fuels used on-site to generate thermal energy 0.09 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:

Thorne Dining Hall, the second largest user of hot water on campus, has a solar hot water system that produces 0.022145 MMBtu per year. There is another solar hot water system on the roof of the Schwartz Outdoor Leadership Center that provides domestic hot water to the kitchen, restrooms and showers of the building (these MMBtus not included).

Unbundled renewable energy products

Unbundled renewable energy products (report kWh):
kWh MMBtu
Purchased RECs, GOs, I-RECs or equivalent unbundled renewable energy products certified by a third party 17,331,000 Kilowatt-hours 59,133.37 MMBtu

A brief description of the unbundled renewable energy products:

In the spring of 2018, as part of Bowdoin's effort to become carbon neutral, the campus purchased RECs to offset all remaining escope 2 (electricity) emissions, and carbon offsets to offset all remaining scope 1 and scope 3 emissions. Bowdoin purchased a total of 9557 wind RECs from Greenlight Energy Group in Oklahoma (9,557,000 kWh). One REC represents the environmental benefits of 1-megawatt hour (MWh) of renewable electricity generated and delivered to the power grid. By purchasing these products, we alone have the right to all associated claims about the environmental benefits they embodie.
