The proposed Nemadji Trail Energy Center (NTEC) in Superior, Wisconsin has hit a setback as its owners withdraw their air permit application, forcing a potential restart of the permitting process due to extended timelines. This decision was made by the partners of NTEC, including Dairyland Power Cooperative, in light of challenges in meeting the construction schedule established by the permit. In Tennessee, a federal appeals court has temporarily blocked the construction of a 32-mile natural gas pipeline intended to supply a new plant, citing potential environmental risks raised by conservationist groups. The court's ruling pauses two essential permits after claims that the pipeline's construction could harm local waterways. The Tennessee Valley Authority plans to replace its coal-fired plant with natural gas, but this transition has sparked criticism from environmental advocates pushing for quicker adoption of renewable energy sources. The legal disputes surrounding both projects underline ongoing tensions between energy development and environmental protection efforts.
