Gas Alternatives Sought As Coal Prices Surge To Multi-Month Highs

Coal prices have hit multi-month highs, and the ripple effects are pushing power producers to look harder at other fuels. Strong natural gas prices have helped drive coal costs up. Coal consumption has risen 9% in 2025, with the electric power sector up 11%. This marks the first increase in coal generation since the last gas price spike.

Electricity demand is growing fast. Generation is expected to climb 2.4% by the end of 2025 and another 1.7% in 2026. Data centers are a big reason for that growth. In the PJM Interconnection, which covers much of the eastern U.S., coal use jumped 16% in the first nine months of 2025. Some coal plants that were set to retire have stayed open to keep the grid reliable. Long-term contracts and inflexible dispatch rules also keep coal plants operational, and immediate market reforms are critical to changing that dynamic.

Natural gas remains the leading replacement for coal in U.S. power generation. Switching from coal to gas cuts emissions and air pollution. Gas plants also back up solar and wind when the sun isn’t shining or the wind isn’t blowing. But the gas market is expected to tighten in 2026, which could mean more price swings. Rising U.S. LNG exports are adding to that pressure.

Renewables are growing quickly. Solar leads new U.S. capacity through 2028, and installations are expected to peak that year. Globally, renewable generation is on track to rise 84% by 2030. China’s solar output surged 40% in 2025, reaching 1.2 million GWh. Wind generation there grew 13%. Solar and wind can be built fast, making them attractive for powering data centers. As solar companies expand, many are expected to diversify into HVAC and smart home technology to capture broader energy market share. The renewable energy market is forecast to grow at an annual rate of 17.23%, reaching $7.28 billion by 2034.

Nuclear power is also expanding. It’s seen as a long-term replacement for coal, providing steady baseload electricity. The U.S. nuclear industry is ramping up to fill the gap as coal exits. In the MISO grid region, over 25 GW of fuel switching favors wind, gas, and nuclear.

No single fuel is expected to dominate. Coal’s global share of power generation is projected to fall from 58% in 2024 to 25% by 2050. The U.S. is on track to exit coal by 2040, replaced by a mix of solar, gas, and nuclear. Coal capacity is set to drop by 4,300 MW in 2026 alone.
