AI boom is making your utility bills more expensive, says BofA, and they’re likely to keep going up

Bank of America economist David Tinsley warns that consumers are indirectly subsidizing the AI boom through rising utility costs, with average payments increasing 3.6% year-on-year in Q3 2025. This surge is attributed to the escalating electricity demand from AI data centers, which strains the power grid and necessitates infrastructure investments that are subsequently passed on to all ratepayers, indicating continued upward pressure on household energy budgets.

Analysis

Bank of America economist David Tinsley highlights that consumers are increasingly bearing the cost of the AI boom through elevated utility bills. Average utility payments surged 3.6% year-on-year in Q3 2025, a direct consequence of the escalating electricity demand from AI data centers. This significant increase reflects the strain on existing power grids and the necessity for substantial infrastructure investments.

The article attributes this pressure to the rapid build-out of AI infrastructure, including projects like Stargate and investments by tech giants such as Microsoft, Google, and Nvidia, which are outstripping electricity supply capacity. This imbalance forces utilities to pass on grid enhancement costs to all ratepayers, including residential, commercial, and industrial sectors. Consequently, rising energy and capacity pricing are expected to continue impacting household budgets.

The analysis suggests that this trend, coupled with increasing residential electrification, will sustain upward pressure on electricity demand and prices over the next decade. This inflationary pressure on a fundamental consumer expense could dampen discretionary spending and impact broader economic stability. The indirect subsidization of the AI boom by consumers represents a significant, under-recognized economic externality.

Key Decisions for Investors

• Consider the inflationary impact of rising utility costs on consumer discretionary spending and corporate operating expenses, particularly for energy-intensive industries.
• Evaluate long-term investment opportunities in grid infrastructure, renewable energy, and energy efficiency technologies that address the growing demand from AI data centers.
• Monitor regulatory responses and potential policy interventions aimed at mitigating the consumer burden or incentivizing grid modernization, as these could create new market dynamics.
