Coal's Unlikely Comeback: AI-Driven Demand Fuels Power Plant Renewal

The resurgence of coal-fired power plants in the US is not what you'd expect. It's not due to environmental concerns being ignored or climate change being dismissed. Instead, it's a direct result of artificial intelligence (AI) data centers devouring massive amounts of electricity.

Data centers consumed approximately 176 terawatt-hours of electricity in 2023 and are projected to balloon to between 345 and 580 TWh by 2028-2030. To put that into perspective, the upper end of that range is roughly equivalent to France's entire annual electricity consumption.

Utilities have postponed retirements of at least 15 coal plants across the country, and the Department of Energy issued emergency orders in 2025 to retain more than 17 gigawatts of coal capacity online. According to Southern Company CEO, 'We will extend coal plants as long as we can.'

Data centers and crypto mining operations compete for cheap electricity, but when AI companies start bidding up power prices, it affects every energy-intensive industry. Bitcoin miners have already experienced this squeeze firsthand, with several large-scale mining operations pivoting to AI hosting or high-performance computing.

As coal capacity stays online to serve AI data centers, the ripple effect hits miners operating in regions with heavy data center buildout: higher power costs, tighter grid constraints, and more regulatory scrutiny around energy consumption. The key variable for investors is the total cost of electricity in data-center-heavy regions, as AI companies absorb more generation capacity.
