Potential Impacts of Replacing Retiring Coal Capacity in MISO with Natural Gas or Wind Capacity


The Iowa Utilities Board (IUB), via funding from the National Association of Regulatory Utility Commissioners (NARUC), retained Synapse to analyze the factors that will affect the choice of capacity to replace coal-fired capacity located in the MISO region that is likely to retire by 2020. The Synapse report presents a high-level analysis of key potential impacts on the region’s wholesale electric and natural gas markets in 2020 for three possible cases of coal capacity retirements and mixes of replacement capacity—a base case, a high gas-fired capacity case, and an additional wind capacity case.
