The sole operational unit of Delaware state's only coal-fired power plant, Indian River Unit 4, will shut down in February 2025, two years ahead of schedule. This early closure, announced by regional grid manager PJM, is expected to save consumers nearly $100 million.

The Indian River Power Plant, located near Dagsboro, has long been a source of environmental concern. It has faced scrutiny for air pollution, groundwater contamination, and potential health impacts on nearby residents. A 2007 study confirmed a "cancer cluster" in the surrounding area with a cancer rate 17% higher than the national average.

The decision comes after Delmarva Power completed necessary transmission upgrades, ensuring grid reliability despite the plant's closure. "Delmarva's good work to complete this project far ahead of schedule is a win for our customers, both from a reliability and affordability perspective," said Mike Bryson, senior vice president – operations at PJM.

The Indian River Power Plant has been a significant source of environmental and public health concerns for decades. In 2009, Citizens for Clean Power sued the plant for over 6,000 violations of state and federal air pollution regulations.

Studies have linked the plant to a "cancer cluster" in the surrounding area and identified high levels of air pollution, including harmful acid gases. Groundwater contamination from the plant's coal ash has also been documented, with concerns about the presence of toxic substances like arsenic and mercury.

More recently, the Environmental Integrity Project confirmed contamination of groundwater with unsafe levels of toxic pollutants found in coal ash, including arsenic, lithium, and mercury. Recent EPA findings have further emphasized the dangers of coal ash, highlighting increased cancer risks and widespread safety violations. These factors have led to numerous environmental lawsuits and ongoing scrutiny of the plant's operations.

The early shutdown marks a significant step towards a cleaner energy future for Delaware. It aligns with the growing national trend of phasing out coal-fired power plants in favor of renewable energy sources. However, the challenge of safely disposing of the plant's coal ash remains. The site contains nearly 1.5 million cubic yards of coal ash and toxic waste, posing a long-term environmental risk.

This development comes as Delaware explores alternative energy sources, particularly offshore wind power. While a recent permit for an offshore wind cable connection to the Indian River plant site was rejected, the state continues to pursue renewable energy initiatives.

The early closure of Indian River Unit 4 signifies a major milestone in Delaware's transition to a cleaner energy future, benefiting both the environment and consumers.
