Empire State Plaza Utility System
A Complex Infrastructure

What does it take to heat and cool 12 million square feet of commercial and office space? When first engineered, the Plaza’s heating and cooling facilities were one of the largest centralized mechanical systems in the world. Still a colossus, the Plaza’s steam plant generates up to 4 million pounds of steam a day. 950,000 gallons of cooling water are continually circulated in a closed loop from one end of the Plaza to the other, and a similar closed-loop heating system warms the Plaza in cooler months.

From the Hudson River to the Sheridan Avenue Steam Plant to the Plaza’s Central Air Conditioning Plant, learn more about the pieces that make up the Plaza’s complex utility system infrastructure.
