The Illinois Commerce Commission (ICC) on Thursday approved plans by utility Ameren Corp. to construct a $1.1-billion, 380-mile high-voltage power line across sections of central Illinois.
Known as the Illinois Rivers Transmission Project, the line will be the largest of its kind in Illinois history as well as the largest undertaken by St. Louis-based Ameren. The utility says the line will promote delivery of low-cost power while improving the reliability and efficiency of the power grid.
