Infrastructure charge approved for Ameren Missouri

JEFFERSON CITY, Mo. (AP) -- Missouri regulators have approved an infrastructure surcharge for natural gas customers of Ameren Missouri.

The Public Service Commission says the surcharge will cost residential customers 75 cents per month.

Ameren Missouri sought the surcharge for infrastructure improvements it has made since the start of 2011. Its costs for replacing and relocating natural gas pipelines are not included in its rates.

St. Louis-based Ameren Missouri, a unit of Ameren Corp., has about nearly 127,000 natural gas customers in Missouri.
