The Zion Energy Center is a peaking facility located in Zion, Illinois, on a 114-acre site.  The construction of the plant was coordinated and managed by Calpine using a general contractor.

These state-of-the-art simple-cycle peaking units are designed to operate on either natural gas or low sulfur distillate oil to ensure maximum operational flexibility and reliability, providing additional power to consumers during peak periods of electricity demand.  The capacity of the three-unit facility is sold into the wholesale power market.  Calpine’s Zion facility provides Illinois with environmentally responsible energy to help meet the state’s growing demand for electricity, while also providing needed diversification for the fuel types.
