2026 Power and Utilities Industry Outlook

The U.S. power and utilities sector is facing a significant surge in electricity demand, with peak demand projected to grow by 26% by 2035 driven by AI data centers and industrial electrification. This growth is testing grid limits as two terawatts of new capacity remain stalled in interconnection queues and reliability pressures mount from frequent billion-dollar natural disasters. Utilities are now shifting from long-term planning to immediate execution, focusing on securing firm capacity and navigating a complex new regulatory landscape following the 2025 reconciliation bill.

According to Deloitte analysis, U.S. electricity demand began accelerating in 2025, far exceeding previous utility projections due to the massive power requirements of artificial intelligence training and the electrification of the transportation and industrial sectors. Data center demand is expected to reach 176 gigawatts by 2035, representing a fivefold increase from 2024 levels, while industrial electrification is slated to add another 25 GW by 2030. Despite this demand, the pace of connecting new energy sources has lagged significantly; although renewables accounted for 93% of new capacity through mid-2025, approximately two terawatts of capacity are currently stuck in interconnection queues, nearly double the total installed capacity of the current grid.

Reliability and affordability have become central concerns for utility operators as the United States experienced 15 natural disasters in the first half of 2025 that each caused over $1 billion in damages. The sector is also adjusting to the 2025 reconciliation bill, known as the One Big Beautiful Bill Act, which rolled back several clean energy incentives and narrowed safe-harbor provisions, thereby compressing developer timelines. To maintain grid stability, utilities are focusing on "firm" capacity, which includes planning nearly 19 GW of gas-powered capacity through 2028 and extending the operational lives of existing coal and nuclear plants to bridge the widening reliability gap created by the retirement of 104 GW of older coal and gas units.

Long-term utility strategies are increasingly revolving around nuclear energy and advanced storage technologies to provide dependable, carbon-free baseload power. The federal government has established a goal to quadruple U.S. nuclear capacity to 400 GW by 2050, supported by $900 million in funding for advanced reactors and the preservation of tax credits for existing fleets under the new legislation. Additionally, the industry is moving toward long-duration energy storage (LDES) to address seasonal reliability gaps, with at least two states already implementing LDES requirements totaling more than 2.75 GW. Utilities are also beginning to view hyperscale data centers as potential operational partners, using AI-enabled orchestration to shift workloads and align demand with renewable energy oversupply.
