A ceremony will be held next week to mark the start of a more than $1 billion energy development in Niles. The Indeck Niles Energy Center at 2200 Progressive Drive will be a natural gas power plant. It’s expected to generate hundreds of thousands of dollars in tax revenue each year for the city of Niles, and create more than 20 permanent jobs. On hand for next Wednesday’s groundbreaking will be Congressman Fred Upton, Niles Mayor Nick Shelton, and former state Senator John Proos, among others. The new plant could be up and running in 2021. Indeck is a power equipment company based in Illinois.
