Utility bills climbed faster than overall inflation during the summer, according to a Bank of America report, adding another source of pressure to household budgets. Summer heat, power grid modernization, and data center construction all contributed to the increase.

Bank of America said consumers could receive some relief in the near term if warmer winter weather reduces demand for heating. Even so, the bank expects pressure from utility costs to remain for some time.

The average utility bill price increased 5.3% year over year in August, Bank of America found. That exceeded inflation in electricity and piped gas prices, which rose 4% from a year earlier following the hottest summer on record in the US.

Energy bills accounted for roughly 3% of total household spending as of 2024. While that represents a relatively limited share of spending, the latest increases are running ahead of broader inflation.

Several large economic shifts are pushing costs upward in parts of the country. Bank of America pointed to reshoring manufacturing, reindustrialization, and the significant need to replace infrastructure across the US.

The impact is not uniform, however, because utility bill growth varies by location. Consumers in different cities and regions have faced sharply different outcomes as investments, regulations, and earlier recovery charges have shaped prices.

In the Northeast, investments in grid capacity and the wider energy network have resulted in higher prices. Florida moved in the opposite direction as regulatory changes and the removal of hurricane recovery surcharges helped bring prices down.

Detroit, Baltimore, and Washington, D.C. recorded the largest increases in energy costs from June through August of this year. Utility bills in all three cities rose 10% year over year, while bills declined in San Jose, Orlando, and Tampa.

Growing electricity demand could keep the pressure alive. The US Energy Information Administration's August 2026 short term energy outlook projects a 4% increase in commercial and industrial electricity consumption, a change that will require new grid investments.

"Accommodating this growth will likely require ongoing investment in grid capacity and power generation, and some of these costs may be passed on to consumers through higher energy bills," Bank of America said.

Data center construction has become a visible part of the debate over rising power costs. Concerns about utility bills have helped generate bipartisan opposition, with a Gallup poll earlier this year finding that seven in 10 Americans oppose data center construction in their local area.

Daniel McGahn, CEO of energy technology company American Superconductor, told Yahoo Finance that new data centers are not typically the sole cause of higher utility bills. He said infrastructure costs are often part of the underlying project rather than automatically shifted to ratepayers.

"A lot of what we see in the build out of all this infrastructure, be it for data or be it for chips, or be it for manufacturing, most of the time … that's part of the cost of the project, of bringing that capacity online," McGahn said. "It's not something that's necessarily passed on to you or I as a ratepayer."

Despite the longer term concerns, Bank of America said the El Niño weather pattern could offer consumers some temporary relief. El Niño produces a temporary warming of the Pacific Ocean that changes global weather patterns, and warmer temperatures could reduce energy demand.

"The most predictable impact from a severe El Niño appears to be unseasonably warm temperatures, implying reduced heating needs during the fall and winter," BofA wrote. Lower heating needs could soften bills after a summer in which utility costs rose faster than overall inflation.

That potential relief comes with a caveat for consumers. If El Niño brings stormy weather to southern parts of the US as expected, households could end up spending more on repairs and maintenance even if warmer temperatures reduce their energy use.
