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.

DOE to Fund Advanced NOx Control Study for Coal Plants

LCG, March 9, 2005--The Department of Energy National Energy Technology Laboratory (NETL) has selected Reaction Engineering International (REI) for a project to evaluate REI's Advanced Layered Technology Approach to reduce NOx emissions in a more cost-effective manner. Lowering capital and operating costs of emission control systems may accelerate the emission control upgrades, reduce emissions, and improve the cost-competitiveness of aging coal plants. The project is part of NETL's Advanced NOx Emissions Control Program that supports the development of advanced technologies to control NOx emissions.

The project will evaluate the ability of the Advanced Layered Technology Approach (ALTA) to reduce NOx emissions below 0.15-lb/MBtu on a cyclone boiler by combining deep staging from overfire air, Rich Reagent Injection (RRI), and an innovative SNCR system. The tests will include firing 100% bituminous coal and bituminous/PRB coal blends. The Electric Power Research Institute (EPRI) and AmerenUE will work with REI on this project.

Relative to more traditional NOx emission control systems, such as selective catalytic reduction (SCR), the benefits of ALTA are lower capital and lifecycle costs and significantly less plant outage time. Tests to be conducted at the AmerenUE Sioux plant will also evaluate the impact on balance-of-plant issues, such as the amount of unburned carbon in the ash, slag tapping, ammonia slip, waterwall corrosion and heat distribution. The tests follow REI's previous experience at Conectiv's 136 MW BL England Unit 1 and AmerenUE's 525 MW Sioux Unit 1 where significant NOx reduction was achieved using RRI and overfire air during the test period.
