The Illinois Commerce Commission (ICC) approved Ameren Illinois’ refiled multi-grid plan with modifications. The Commission approved $356 million in investments and system improvements needed to strengthen power grid reliability and support the ongoing electrification of the state’s power system. The decision cut the utility’s proposed $1 billion in spending by approximately 66 percent.
ICC Commissioner Stacy Paradis explains, “Grid planning is not a one-task. It is a dynamic, iterative process that will require continued refinement and adaption in future grid plans,” Paradis continues, “ The grid of the future will be shaped by emerging technologies, evolving regulatory review, and changing energy demands. To meet these challenges, the utilities, ICC staff, advocacy groups, and other stakeholders must continue to work together.”
Ameren’s grid plan is consolidated with its multi-year rate plan to determine which system maintenance and upgrade costs can be passed on to ratepayers at a reasonable cost. In accordance with the Public Utilities Act, these costs are only recoverable if the utility demonstrates they are reasonable and prudent.
The ICC’s decision reduced Ameren’s rate increase request by 7 percent for an overall increase of $309 million.
The impact of the decision on individual customers will vary on service class and energy usage.
