DOE Acts to Ensure Key Coal-fired Power Plants Are Available in MISO to Supply Peak Summer Demands

LCG, May 18, 2026--The U.S. Secretary of Energy today issued an emergency order to address critical grid reliability issues in the Midwest anticipated this summer. The order is in effect beginning on May 19, 2026, through August 16, 2026. The emergency order directs the Midcontinent Independent System Operator (MISO), in coordination with Consumers Energy, to ensure that the J.H. Campbell coal-fired power plant (Campbell Plant) in West Olive, Michigan shall take all steps necessary to remain available to operate and to minimize costs for the region.

EPA Announces Proposed Rule Action to Revise ELG's and Support Reliable, Affordable Coal-fired Power Plants

LCG, May 14, 2026--The U.S. Environmental Protection Agency (EPA) announced today that it is proposing a rule to revise wastewater limits, known as effluent limitations guidelines (ELG), for steam electric power plants that will help improve grid reliability and lower electricity prices while continuing to support clean and safe water resources. If finalized, the EPA's proposal is estimated to reduce electricity generation costs by as much as $1.1 billion annually, which could provide cost-savings to American consumers.

Arizona Corporation Commission Rejects Utilities' Integrated Resource Plans

LCG, March 22, 2018--The Arizona Corporation Commission last week rejected the Integrated Resource Plans (IRPs) filed by Tucson Electric Power Co. (TEP), sister utility UniSource Energy Services (UNS) and Arizona Public Service Co. (APS) and has ordered them to develop plans that reduce their dependence upon natural gas and new, gas-fired power plants. The Commission prefers greater reliance on renewable energy and storage.

The Commissioners voted 3-2 to reject the resource plans. However, the Commission unanimously approved the final order to reject the plans. The Commission did not accept a Commission Staff recommendation to approve that the resource plans. The Commission placed a moratorium through 2018 on the purchase of any natural-gas power plant with a generating capacity greater than or equal to 150 MW. Furthermore, the Commission approved a new process to revamp the rules.

The three electric utilities are required to file IRPs every two years. The IRPs include 15-year forecasts of energy demand and supply resources to meet that load, including a three-year action plan.

The Commission adopted a new proposal that requires the utilities to prepare IRPs that include at least one supply portfolio where the addition of fossil fuel resources does not exceed 20 percent of all resource additions. Furthermore, a proposal was supported to add scenarios including a least one gigawatt of energy-storage capacity, and at least 50 percent "clean energy resources," including biomass energy and energy efficiency measures.

An APS spokesperson stated, "Our plan keeps Arizona on course for a cleaner energy future, so we respectfully disagree with the Commission's decision not to acknowledge any IRPs (integrated resource plans) even after Commission Staff determined they were complete and responsive to the filing requirements. We all agree on the goal of cleaner energy, and this decision doesn't change that - or how we will meet our customers' energy needs in the near-term."
