US power prices climb 18% as AI demand fuels $9.2B rate hikes
President Trump's pledge to halve US electricity prices has ended in an 18% increase, exposing a structural supply deficit that is forcing utilities to pass massive AI-driven grid costs onto consumers.
The 18-month deadline for President Trump’s pledge to slash electricity bills by half expired this week. On the campaign trail, he promised that by mid-2026, "your electric bill... will be 50, 5-0 percent, less." Instead, U.S. Energy Information Administration data shows residential electricity rates have risen 18% since his January 2025 inauguration.
For markets, the political shortfall is secondary to the structural pricing crisis it highlights. The US power grid is caught between surging demand and contracting supply, driving up costs for utilities, data center developers, and consumers. In the 12 months through April, electricity rates climbed 7.3%, roughly double the broader rate of inflation.
The financial strain on the system is visible in regulatory filings. Utilities filed $9.2 billion in rate-hike requests in the second quarter of 2026, up 26% from a year earlier. These filings suggest the recent price increases are merely a down payment on future costs, as providers attempt to recover expenses from a grid under severe stress.
The primary cost driver is the AI boom. Data centers are consuming electricity at volumes the current infrastructure was not built to handle, adding an estimated $6 billion to the latest capacity auction costs at PJM Interconnection. As the nation’s largest grid operator, PJM posted a total capacity price of $16.4 billion for the 2028-2029 period, tying a prior record high. Because these capacity costs guarantee future power supply, they flow directly through to customer bills.
Meanwhile, policy decisions have constricted the supply needed to meet this demand. The administration paid TotalEnergies nearly $1 billion to cancel planned offshore wind projects, deliberately reducing future generating capacity. This occurred alongside the continued closure of legacy coal and natural gas plants, which have steadily pulled baseload power off the grid.
The collision of these dynamics creates a challenging environment for energy markets. Power prices are moving sharply opposite to administration targets, turning the electricity sector into a persistent source of inflationary pressure. For investors, the math is straightforward: as long as AI demand outpaces the replacement of retiring generation, grid capacity will remain expensive, and utility rate cases will continue to climb.
