Vassar College Steam Turbine Optimization(ST9190-1)

Vassar College


Vassar College currently consumes 20.2 million kWh of electricity, 0.55 million Ccf of natural gas, and 0.9 million gallons of fuel oil each year. Vassar operates a central heating plant for seven months out of the year with a steam capacity of 95,000 lbs./hr. for the main campus. The plant currently includes a 750 kW backpressure steam turbine that normally operates when ambient temperature is below 40 Deg F. Vassar College is located in Poughkeepsie, NY and first admitted students in 1865. The campus totals 1,000 acres with over 2.4 million square feet in buildings. Vassar has a student body of 2,400 and 1,200 employees.

Project Description

This project will be the first NYSERDA DG/CHP project in Central Hudson territory. The project will feature a unique tandem operation of steam turbines to maximize efficient turndown. Two new high efficiency boilers will be used to generate steam.


The demonstration project will result in the following benefits: (1) Reduced on-site energy costs (2) Reduced on-site criteria air pollutants (NOx, SOx, CO, PM, VOC) (3) Improved power reliability for host site (4) Reduced greenhouse gas emissions (5) Reduced electric power peak load on the grid
