Total energy consumption, performance year:
11,364.72 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) 103,884.71 Kilowatt-hours 354.45 MMBtu

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

N/A: College of the Atlantic purchases unbundled RECs


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

1. 25kW: COA currently has a residential 2.4kW wind turbine, installed by students enrolled in the Practicum in Wind Power course, as well as nine solar arrays, installed by students enrolled in several different courses covering renewable energy, totaling 25kW of rated peak capacity.
2. 50kW: The college has 50kW of solar capacity, installed by ReVision Energy of Liberty, Maine under a Power Purchase agreement, on its Kathryn W. Davis Student Housing and at its nearby Peggy Rockefeller Farms.
3. 103kW: COA’s most recently constructed building, the Davis Center for Human Ecology, has 103kW of installed solar on the roof under a Power Purchase agreement with ReVision Energy of Liberty, Maine.


Clean and renewable thermal energy (report MMBtu):
MMBtu
Clean and renewable stationary fuels used on-site to generate thermal energy 491.64 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:

In 2008, COA installed a 535,000 Btu central wood pellet boiler that provides heat and domestic hot water to 28,500 square feet of building space, including Katherine W Davis student residences and Deering Common. The wood pellets are manufactured in Maine, and are 100% wood, including clean wood chips and sawdust from sawmills. They contain no additives or binders, such as oil or plastic. COA’s most recently constructed building, the 29,000 square foot Davis Center for Human Ecology, is entirely electric, and therefore does not use stationary fuel. COA is currently transitioning other buildings on campus from heating oil to air source heat pumps.


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

N/A: College of the Atlantic does not import steam, hot water, and/or chilled water (renewable or otherwise).


Unbundled renewable energy products (report kWh):
kWh MMBtu
Purchased RECs, GOs, I-RECs or equivalent unbundled renewable energy products certified by a third party 431,400 Kilowatt-hours 1,471.94 MMBtu

A brief description of the unbundled renewable energy products:

College of the Atlantic purchases Renewable Energy Credits from Constellation New Energy, which are called New Wind Mix, and are generated by wind farms in the Midwest and Southwest. These RECs are Green-E certified.


Total clean and renewable energy generated or purchased:
