Ameren Missouri filed a $1 billion infrastructure plan with the Missouri Public Service Commission on Monday, proposing a way to replace aging infrastructure.
Ameren plans to update the existing infrastructure system, citing the age of current components. In the filing, the company said its four baseload coal generation plants average about 50 years old, about half of its substations are more than 40 years old and its underground network serving downtown St. Louis has facilities that are 80 to 100 years old.
The company said the investment package could bring thousands of jobs to the region, including by attracting businesses to a smart grid system, which reduces outages customer costs.
The filing also called for a new way to calculate rates in Missouri to include infrastructure investment, citing current regulatory lag preventing power companies from investing.
It called for immediate action to improve the regulatory framework in the state, similar to a measure that failed in the state legislature last session.
