Award Winning Relationship

A relationship built on 10 years of trust.

Campus Overview

Princeton University’s central energy plant is a district energy plant providing chilled water, steam, and electricity to the university campus. 

The plant has four main components: steam boilers, water chillers, an electric generator, and a large thermal energy storage system.

  • TES: 2.6 MM Gallon Tank or 40,000 ton hours of capacity
  • Chillers: 20,000 ton hours
  • Plant Boilers:  300,000 lbs. of steam per hour
  • General Electric LM-1600 gas turbine: 15 megawatts of electricity

As a leader in the academic world, they are a leader in the drive towards sustainability with a Net Zero goal by 2046 their 300th anniversary.  Read the plan at Sustainability Action Plan  

Our History

Princeton has played a critical role in the history of Smith Engineering. The university was one of our initial customers and as we have grown as an organization so has our relationship with Princeton.

In 2017, Princeton University and Smith Engineering won the IDEA Innovation Award for the booster chiller project.

“They teamed up to solve a complex, chronic low delta T in a campus engineering building with a heat concentrating chiller that yielded outstanding results – in both operational efficiencies and cost savings.”
