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 the AI boom is indirectly increasing consumer utility costs, with average payments rising 3.6% year-on-year in Q3 2025 due to surging electricity demand from data centers. Despite massive investments in AI infrastructure, the electricity grid is strained, leading to higher energy and capacity pricing as grid enhancement costs are passed to all ratepayers. This persistent supply-demand imbalance is projected to further pressure household budgets and could act as a headwind for overall consumer discretionary spending.

Analysis

Bank of America economist David Tinsley reports that the artificial intelligence boom is indirectly increasing consumer utility costs, with average payments rising 3.6% year-on-year in Q3 2025. This escalation is primarily driven by the soaring electricity demand from data centers powering AI infrastructure, which is straining the existing grid and necessitating significant investment. Despite massive private sector capital injections, including the $500 billion Stargate project and billions from tech giants like Microsoft, Google, and Nvidia, electricity supply struggles to keep pace.

The strain on the grid leads to higher energy and capacity pricing, as costs for transmission and distribution enhancements are incorporated into tariffs for all ratepayers. This mechanism contributes to inflationary pressures on household budgets, with Tinsley predicting "further upside ahead" for utility prices. Harvard economist Jason Furman noted that data center investments were a significant contributor to H1 2025 US GDP growth, highlighting the economic scale of this infrastructure build-out.

This persistent supply-demand imbalance, exacerbated by manufacturing growth and residential electrification, poses a macroeconomic headwind. Rising utility bills are expected to pressure overall consumer discretionary spending, particularly impacting lower-income households already facing slowing wage growth. The situation underscores a critical challenge where technological advancement creates significant demand-side pressures on essential services.

Key Decisions for Investors

• Investors should closely monitor the persistent inflationary impact of rising utility costs on consumer discretionary spending, as this could dampen performance in retail and consumer-facing sectors.
• Evaluate investment opportunities in companies providing grid infrastructure, energy generation, and transmission solutions, given the significant and ongoing need for capacity expansion to support AI and electrification demands.
• Consider the potential for margin pressure on businesses with high energy consumption, while assessing the long-term growth prospects of AI-related tech companies (e.g., MSFT, GOOG, NVDA) which are driving this demand despite the negative macro externality.
