Ameren Illinois building two substations to bolster Madison County power grid
As part of updates to the area’s energy grid, Ameren Illinois is building two transmission substations in Madison County, with the focus on Troy and Collinsville.
Larger in size and scope than average neighborhood distribution substations, these new structures lower received voltages for transfer to distribution substations. Those stations then lower the voltage further for delivery to small transformers, and on to delivery and use by customers.
“This project is a key step in our long-range plans to construct a more robust electric grid to meet our customers growing needs,” Richard Mark, chairman and president of Ameren Illinois, said. “We’re excited to bring these innovative enhancements to our customers in Madison County.”
Improvements will include a 345/138kV substation in Troy, as well as a 138kV substation in Collinsville. Both will tie into the Collinsville Canteen Substation and be supplemented by power line enhancements and circuit additions.
Such improvements have been underway since 2012, and have already led to an average 17 percent increase in region reliability, according to Ameren Illinois.
