St. Louis-based Ameren Corp. and other utility companies are expressing concern that a federal plan to cut carbon emissions poses a threat to the reliability of the U.S. electrical grid. That issue surfaced at a conference last week in St. Louis, where the Federal Energy Regulatory Commission sought feedback about the Environmental Protection Agency’s plan to reduce emissions.
Among the chief points of contention raised at the conference was the EPA’s interim carbon goal for 2020. The EPA already is requiring states to write plans for cutting carbon emissions 30 percent by 2030, and some are suggesting the agency should do away with the 2020 goal.
That interim deadline, they say, will cause utilities to retire coal-fueled power plants before sufficient renewable and natural gas plants are ready to replace them.
