CUP Upgrade Project

MIT’s Central Utilities Plant (CUP) produces on-campus electricity and steam through a combined heat and power (CHP) process, also known as cogeneration – a highly efficient method of generating electrical and thermal power simultaneously. At the heart of the cogeneration facility is a natural gas turbine that has been running since 1995 and is now nearing the end of its useful life. 

The CUP Upgrade Project will replace the aging turbine with new equipment, add a second new turbine at the same location, and complete additional system upgrades to increase energy efficiency and improve the resiliency of the campus. The upgraded system will serve MIT for at least the next 20 years.

MassDEP public hearing May 22

MassDEP has issued a proposed Comprehensive Plan Approval (CPA) following the determination that proposed upgrades to MIT’s Central Utilities Plant will comply with state and federal air quality regulations and state noise policy. In addition, MassDEP has issued a draft Prevention of Significant Deterioration (PSD) permit, which states that the project complies with EPA New Source Review (NSR) regulations (as part of the 1977 Clean Air Act Amendments). Both documents are available for public review up until 5 PM on Tuesday, May 23, 2017.

Public hearing:
          Monday, May 22, 2017, 7:00 PM
