Do you worry that prioritizing new fossil fuel capacity will lead to higher utility bills?
Developers in the United States have announced plans for 68 gigawatts of new fossil fuel capacity through 2030, a 45 percent increase from late 2025 levels. This surge in planned natural gas generation projects is largely driven by the rapid expansion of energy-intensive data centers.
Why it matters
Rising reliance on natural gas for power generation may expose business ratepayers to increased fuel price volatility as capacity targets grow. Operators should prepare for potential supply chain delays, as shortages in equipment like gas turbines could stall these aggressive development timelines.
Developers have slated 68 GW of new fossil fuel capacity between 2026 and 2030, a 45 percent surge from the 47 GW planned in late 2025. While plant owners aimed to retire 8.5 GW of coal last year, only 1 GW actually went offline, marking the lowest retirement levels since 2009.
The details
The expansion is centered on natural gas, which now accounts for 30 percent of the nation's total planned energy capacity. Developers are struggling with infrastructure constraints, specifically a shortage of gas turbines required to bring these projects online. These bottlenecks, combined with a slower-than-expected coal retirement schedule, indicate significant friction in the shift toward newer generation sources.
Timeline
2009: Coal retirement levels were previously as low as last year's figures.
Last year: Owners sought to retire 8.5 GW of coal capacity.
Late 2025: Planned fossil fuel capacity totaled 47 GW.
2026-2030: Developers plan to build 68 GW of fossil fuel capacity.
Market Landscape
This pipeline expansion marks a departure from the steady pace of coal retirements observed since 2009. The shift highlights a trend where grid operators are prioritizing new natural gas capacity to meet the surge in demand from the data center buildout.
Business owners should monitor their local utility's power procurement strategy, as increased reliance on natural gas could lead to higher utility bills if fuel prices fluctuate. Facilities teams should also anticipate potential grid reliability risks linked to these capacity development delays.
The takeaway
The data center-driven expansion of fossil fuel power reverses a decade of retirement trends. Business operators should factor potential volatility in energy costs into long-term overhead projections until new capacity is successfully brought online.
