Option 1

MMBtu
None
A brief description of on-site renewable electricity generating devices :
Carleton's second wind turbine, a General Electric XLE 1.6 MW turbine, was installed in the Fall of 2011 and provides electricity directly to Carleton's electric grid. Carleton also has a 9 kW solar PV array which produces an annual average of 10 MWh per year. The number was lower in FY17 due to maintenance.
Option 2
0
MMBtu
None
A brief description of on-site renewable non-electric energy devices:
Carleton has a solar panel array on its Cassat-James residence Hall which provides solar thermal heating for domestic hot water. We do not currently have the ability to measure cumulative btu production.
Option 3
0
MMBtu
None
A brief description of off-site, institution-catalyzed, renewable electricity generating devices:
Carleton installed its first commercial-sized wind turbine in 2004. This 1.65 MW turbine is connected to the public utility grid and provides 4000 - 4700 MWh of electricity annually. Both the power and the Renewable Energy Credits are sold to the public utility, so Carleton cannot count this production as an offset to its annual GHG emissions inventory.
Option 4
14,064
MMBtu
A brief description of the RECs, GOs and/or similar renewable energy products, including contract timeframes:
Carleton recently started purchasing RECs through our utility provider, through their Renewable Connect Program. We purchase RECs in an amount of the power we deliver to the grid from our first wind turbine.
