U.S. Power Sector Poised for Natural Gas Demand Records Through 2027
The U.S. electric power sector is entering a period of sustained reliance on natural gas, according to the May 2026 Short-Term Energy Outlook from the Energy Information Administration. Despite a broader expansion of renewable energy capacity, rising commercial and industrial electricity requirements—fueled by a surge in data centers and manufacturing—are set to push natural gas consumption to historic peaks by the summer of 2027.
Key Takeaways
- Natural gas usage for power generation is expected to hit 43.7 billion cubic feet per day (Bcf/d) this summer, matching 2025 levels and remaining 4% above the five-year average.
- By summer 2027, demand is projected to climb to 46.1 Bcf/d, exceeding the previous 2024 record by 3%.
- Renewable energy generation is forecast to rise to 25% of the total U.S. electricity mix by 2027, up from 21% in 2025.
Regional Drivers of Energy Consumption
The anticipated record consumption in 2027 is heavily anchored in the West South Central and Mid-Atlantic regions. Large-scale industrial and commercial developments, including new manufacturing plants and high-capacity data centers, are exerting significant pressure on the grid. In Texas, the Electric Reliability Council of Texas (ERCOT) expects a 20% increase in commercial and industrial demand between 2025 and 2027, partly driven by the electrification of oil and gas operations. To meet these needs, ERCOT is projected to boost its natural gas-fired generation by 22% over this two-year window.
The Shift in National Generation Mix
The PJM Interconnection, serving the Mid-Atlantic, is following a parallel trajectory. Faced with increasing computing facility demand, PJM is expected to see a 6% rise in natural gas consumption for electricity production by the summer of 2027. Simultaneously, the region is aggressively expanding its renewable footprint, with solar generation expected to grow by 32% during the same timeframe. Nationally, the decade-long transition away from coal toward a hybrid model of natural gas and renewables remains the dominant trend, providing a balanced, albeit increasingly gas-dependent, framework for maintaining grid reliability amid rising cooling and operational demands.
