Case Study: Clark University achieves cost savings and resilience with Cummins cogeneration solution

University Increases Cost Savings With Reliable Cogeneration Solution

Clark University, a private research university in Worcester, Massachusetts, needed to replace its aging 1.8 MWe slow-speed cogeneration generator after 32 years of service. The school was looking for a compact, reliable gas generator that could fit in the existing space, run continuously in grid-parallel mode, and meet current EPA/MADEP emissions requirements while supporting both electrical and thermal energy needs. Cummins provided the cogeneration solution, including a 2,000 kWe QSV91G lean burn gas generator set with a PowerCommand® controller.

Cummins installed the new generator to supply power and heat across the campus through the existing distribution system, with exhaust heat recovered to produce steam and jacket water heat recovered for hot water. The system improved overall efficiency, reduced electricity purchases from the National Grid, and allowed excess power to be exported for additional savings. Cummins also helped address space, air quality, and noise constraints during installation, enabling the project to meet utility incentive deadlines and achieve a successful start-up and commissioning.
