Should the U.S. continue expanding fossil fuel power plants despite cheaper renewable energy options?
U.S. power developers have increased natural gas projects to their highest level since 2016, with 68 gigawatts of capacity scheduled to enter service between 2026 and 2030. This expansion occurs despite onshore wind and solar energy remaining more cost-effective on an unsubsidized, levelized basis.
Why it matters
Operators face rising electricity demand projections of 25% to 50% between 2025 and 2050, prompting a pivot toward reliable fossil-fuel base load generation. This shift prioritizes grid availability over the lower production costs of renewable alternatives during a period of intense capacity competition.
Fossil plants now represent 30% of the 285-gigawatt national power pipeline, with 68 gigawatts planned for 2026-2030 versus a prior 2025 projection of 47 gigawatts. Combined-cycle gas costs $90 per megawatt-hour, significantly higher than the $68 and $69 for wind and solar.
The details
Developers are responding to anticipated supply shortages by opting for gas-fired capacity despite the higher unsubsidized, levelized costs compared to renewables. The industry expects fossil fuels to comprise 70% of new capacity additions in 2030 to meet the rapid growth in electricity demand. This strategy favors the immediate availability of gas power for grid stabilization over the cheaper, yet variable, intermittent renewable sources.
Timeline
2016: Fossil capacity hit its previous high level.
2025: Previous projection of 47 gigawatts for 2026-2030.
Q2 2026: Snapshot date for the 285-gigawatt power pipeline.
2026-2030: Planned service period for 68 gigawatts of fossil capacity.
2025-2050: Projected period for U.S. electricity demand growth.
Market Landscape
The push for gas-fired power marks a departure from the recent trend of renewable-dominant capacity additions tracked in the 285-gigawatt U.S. power pipeline. This investment shift aligns with utility responses to sustained load growth that current solar and wind project timelines struggle to address.
Businesses should anticipate higher grid-reliance costs as utilities pass through the premiums of more expensive gas-fired generation. Factor potential volatility in long-term electricity pricing into your capital expenditure models given the projected 25% to 50% rise in national demand.
The takeaway
Operators must recognize that grid availability is currently being prioritized over the lower per-unit cost of renewables. Watch the pace of these fossil-fuel project activations in 2026 as a leading indicator of energy pricing trends for your facility's operational costs.
