• U.S. electricity consumption is projected to reach record highs in both 2026 and 2027, driven by AI data centers, manufacturing, and electrification, according to the Energy Information Administration.
  • Power demand is expected to rise from 4,195 billion kWh in 2025 to 4,356 billion kWh in 2027, a 3.8% increase.
  • Renewables’ generation share is projected to reach 27% by 2027, while coal falls to 15%.

Record Demand Strains Grid

U.S. electricity consumption is on track to set new records over the next two years, propelled by the rapid expansion of artificial intelligence data centers, a resurgence in domestic manufacturing, and the electrification of transportation and heating. The Energy Information Administration (EIA) now expects total power demand to climb from 4,195 billion kilowatt-hours in 2025 to 4,356 billion kWh in 2027, an increase of 3.8%.

The surge marks a sharp departure from nearly two decades of stagnant demand growth. Cloud computing and hyperscale facilities laid the groundwork, but the AI boom is accelerating the trend, with data centers alone projected to account for a growing share of national electricity use. A 2026 Department of Energy study estimates that data centers consumed about 192 terawatt-hours in 2024—roughly 4.7% of U.S. electricity—and could reach 9.5% to 15.3% by 2030.

Generation Mix Shifts

To meet the rising load, renewable sources are expected to play a larger role. The EIA projects solar generation will jump 21% in 2026 and another 18% in 2027, lifting renewables’ overall share to 27% by 2027. Natural gas remains the largest source at 40%, while nuclear holds steady at 18%. Coal’s contribution is forecast to slip to 15%, though that figure may reflect a recent revision; earlier September estimates put coal at 14%.

“What institutional investors like us are really focused on is regulatory stability,” said one industry executive at a recent conference, speaking about the broader investment climate. “The U.S. has been on a steady growth trajectory, but the pace of grid expansion is a concern.”

Grid Bottlenecks and Regional Constraints

The main challenge is whether power plants and transmission lines can be built fast enough to keep up. Grid infrastructure typically takes several years longer to construct than data centers, creating a bottleneck that could delay new facilities. The Congressional Research Service (CRS) notes that connection delays and power availability are increasingly determining where and when AI facilities can operate.

Regional disparities are already emerging. The EIA reduced its 2027 electricity-sales forecast for the West South Central region by 4.7% from the previous outlook, reflecting a pause in connecting new Texas data centers. Texas officials ordered a halt to new data center connections in ERCOT pending verification and auditing. New York temporarily paused state environmental permits for new data centers in July 2026, citing concerns over electricity bills and grid reliability.

Policy Responses and Cost Allocation

Federal regulators are moving to address the expected strain. In June 2026, the Federal Energy Regulatory Commission (FERC) launched a proceeding requiring regional grid operators to demonstrate that their interconnection rules can handle large loads. A month later, FERC directed the North American Electric Reliability Corporation to develop standards for computational loads, with proposed requirements due by the end of 2026.

The administration’s “Ratepayer Protection Pledge,” introduced in March 2026, calls on major technology companies to cover their energy and infrastructure costs, though CRS emphasizes that the pledge is voluntary and lacks enforcement. State regulators remain key to cost allocation.

Investment and Procurement Trends

Higher demand is spurring investment in generation and grid infrastructure, but uncertainty around project completion complicates planning. Developers are increasingly turning to long-term power-purchase agreements and “bring your own power” arrangements. Among announced on-site generation projects, natural gas turbines and engines are the leading option, followed by nuclear and fuel cells.

“It’s a great country to invest here because there are a lot of very good companies and the market here is not as competitive as other markets,” said one private equity executive, commenting on the broader investment landscape. “You can create your own ideas.”

Still, not all announced projects will materialize. A May 2026 investment-bank analysis estimates that only 50% to 60% of data-center capacity scheduled for the next one to two years will open on time. The EIA’s long-term outlook projects electricity consumption growth of 0.9% to 1.6% annually through 2050, with data centers a major factor.

Global Context

The U.S. trend mirrors a global rise in electricity demand. The International Energy Agency’s July 2026 update forecast global demand growth of 3.6% in 2026 and 3.8% in 2027, driven by industry, cooling, and digital infrastructure. China is expected to see 5.5% growth in 2026, led by manufacturing and EV charging. Renewables are poised to overtake coal globally in 2026, yet global power-sector emissions are still projected to rise 1% that year before plateauing in 2027.

The decisive issue is not merely whether demand hits another record, but whether new generation, transmission, and enforceable cost-allocation rules arrive in step with it.
