US energy utilities are increasing investments to support rising electricity demand from data centers, electrification trends, grid modernisation, and infrastructure resilience initiatives. A recent report titled “Utility Spending is Rising: A Review of Utility Capital Expenditure Plans”, analyses recent earnings calls of 51 investor-owned utilities (IOUs) to assess planned utility capital expenditure (capex) trends and their potential implications for future utility rate increase requests, at a time when electricity affordability is becoming an increasing concern for consumers and regulators.
The report, released by Washington, D.C.-based PowerLines, a non-profit organisation focused on energy affordability and regulatory reform, found that IOUs are planning a capex of at least USD1.4 trillion through 2030, representing an increase of more than 21 per cent compared to the USD1.1 trillion outlined in five-year spending plans reported a year earlier. These expenditures include investments in physical infrastructure such as power plants, transmission lines, and distribution networks. According to PowerLines, utility bills have already increased by approximately 40 per cent since 2021, while utilities requested USD31 billion in rate increases during 2025 alone.
The study notes a strong historical relationship between utility capex and both rate increase requests and retail electricity prices. Based on historic cost-allocation patterns, residential consumers, which accounted for 47 per cent of total electricity spending last year, could ultimately bear more than USD700 billion of the planned expenditure. The report also highlights that the 10 largest utility spending programmes account for USD707 billion, or nearly 53 per cent of all proposed capex nationwide.
Historically, actual utility spending has closely tracked projections, averaging about 95 per cent of forecast levels over the past decade. Regionally, utilities in the South account for nearly half of planned capex, exceeding USD500 billion, driven by growing demand and grid hardening against severe weather. Utilities in the Midwest and West are each expected to invest more than USD200 billion, while utilities in the Northeast are projecting close to USD200 billion for infrastructure replacement, resilience and transmission modernisation.
The report concludes that significant investment will be required to modernise the ageing US grid and maintain reliability, but argues that current regulatory frameworks encourage capital-intensive projects over lower-cost alternatives. PowerLines states that utilities could potentially mitigate future rate pressures by leveraging growing electricity demand to spread fixed costs across a larger customer base and by prioritising energy efficiency measures, demand-side management solutions, and grid-enhancing technologies that maximise the use of existing infrastructure. Further, stronger regulatory oversight and policy reforms will be necessary to balance grid modernisation needs with consumer affordability concerns in the years ahead.
