The debate over the future of energy in the Midwest has taken on new urgency as environmental advocacy groups challenge a federal initiative intended to hasten the connection of new power plants to the regional grid. At the heart of the dispute is a proposed natural gas facility in Wisconsin, drawing significant criticism from those advocating for renewable energy sources.
Acting on behalf of Clean Wisconsin and the Natural Resources Defense Council, Earthjustice, a nonprofit law firm focused on environmental issues, initiated legal proceedings against federal energy officials. The Sierra Club has opted to represent itself in this legal challenge.
This legal action requests the U.S. Court of Appeals for the D.C. Circuit to evaluate two orders issued by federal regulators earlier this year. These orders involve the Midcontinent Independent System Operator (MISO), which manages the electric grid in the Midwest, and its plan for rapidly integrating new power plants.
One of the controversial orders endorses MISO’s Expedited Resource Addition Study (ERAS), which aims to quickly bring new energy resources online to meet what MISO describes as an “unprecedented” increase in demand and reliability challenges. The other order rejected a rehearing on this plan.
While the Federal Energy Regulatory Commission (FERC) has refrained from commenting on the ongoing litigation, MISO has acknowledged the lawsuit and is observing the legal developments closely.
Critics of the fast-tracking initiative argue that it favors fossil fuel projects over clean energy alternatives. According to Earthjustice attorney Ada Statler, federal regulators are allowing grid operators such as MISO to “rewrite the rule book to the benefit of fossil fuel and data center companies,” which sidelines renewable energy projects.
Clean Wisconsin’s energy and air manager, Ciaran Gallagher, expressed frustration over the prolonged waiting period for clean energy projects. “Some projects have been in line for five years, while those selected for the fast-track program get to skip the line,” Gallagher noted.
In September, the first batch of 10 projects for the ERAS program was announced by MISO. These projects, which include five natural gas plants, three solar projects, one wind, and one battery project, will collectively add 5.3 gigawatts to the grid. Despite the equal number of gas and renewable projects, the natural gas plants are expected to contribute significantly more energy, totaling about 4,300 megawatts compared to 974 megawatts from renewables.
One focal point of the legal dispute is the Red Oak Ridge Energy Center, a proposed natural gas facility in Kenosha County, Wisconsin, projected to generate over 1 gigawatt of power. The developer is seeking state approval for construction, while We Energies, a major utility in the state, plans to acquire the project to meet growing energy demands from data centers, also incorporating seven solar projects into their strategy.
As utilities emphasize the necessity of natural gas to meet energy demands, Gallagher criticized the reliance on fossil fuels. “MISO and utilities are stuck in an old mindset of how to operate the electricity system,” Gallagher said, advocating for a focus on carbon-free energy sources and faster integration of storage solutions into the grid.
