Boiler Replacement & Cogeneration Project
This combined heat and power project utilized excess steam energy to generate electricity for campus consumption, offsetting electricity currently purchased from the grid.

Contractor:
H.P. Cummings - Winthrop, ME
The project consisted of replacing two aging and inefficient oil-fired steam boilers with a new high-efficiency low-emissions, dual-fuel (natural gas and #2 oil) 60,000 PPH boiler during the summer of 2010 and the installation of a backpressure steam turbine generator during 2011 to create both heat (steam) and electric power (600kW) for the campus. Benefits of this project include:
- Reducing annual campus kWh consumption from the grid by nearly 10% (1.749 million kWh)
- Reducing annual greenhouse gas emissions by more than 18% of the College’s 2008 net emissions (2,400 tons CO2e avoided)
- Improving energy efficiency (now 80%+ versus 48% previously) and reducing overall annual campus BTU consumption by 6% (6,250 dTH)
