A new report by consulting firm ICF has projected that the overall demand for energy from the electric grid in the United States, known as “load,” will increase by 25% by 2030 and 78% by 2050.
This surge in demand is attributed to several factors, including the electrification of the transportation and building sectors, the rising power needs of data centers associated with artificial intelligence and cloud services, as well as industrial manufacturing.
To address this anticipated growth while maintaining affordable energy costs and high reliability for customers across the U.S., significant upgrades to the electrical grid and scaling of innovative energy technologies will be necessary.
Consumer electricity rates are also expected to rise significantly in response to this increase in demand.
According to ICF’s analysis of four utilities nationwide, residential electricity rates could increase between 15% to 40% by 2030 compared to rates in 2025.
For instance, customers of DTE Energy in Michigan could see their costs rise from just over 20 cents per kilowatt-hour to nearly 30 cents per kilowatt-hour in the same timeframe.
By 2050, some regions may face doubled electricity rates.
Regional variations in demand growth are anticipated, with the Intermountain West expecting relatively modest growth in both overall and peak electricity demands through 2035.
Conversely, states such as Virginia, North Carolina, Georgia, and Texas are forecasted to experience high overall electricity demand growth.
The reliability of the electricity grid is also at risk as many areas will likely see their reserve margins—essentially the excess capacity that utilities maintain to meet peak demand—fall below target levels as early as 2030.
Without new resources, including solar and battery storage systems, utilities may be forced to deny interconnection requests from rapidly growing sectors, notably the expanding data center industry.
To meet this rising electricity demand, the U.S. will need to construct approximately 80 gigawatts (GW) of additional electric capacity annually over the next two decades.
This contrasts starkly with the average of 40 GW built each year over the past five years.
ICF has analyzed the types of energy generation resources likely to be developed, drawing on data from the U.S. Energy Information Administration.
The forecast suggests that solar, wind, and battery storage will represent the majority of new capacity installed by 2050.
More specifically, solar energy is anticipated to account for around 30% of this new capacity, with battery storage and onshore wind each representing nearly 20%.
The remaining 30% will derive from a mixed bag of natural gas, offshore wind, nuclear power, and other energy resources.
However, quickly adding new generation capacity poses significant challenges, primarily due to supply chain constraints and the critical need for upgrades to transmission and distribution systems.
In response, utilities, grid operators, and local governments are exploring load management solutions, such as rooftop solar and battery storage, which can produce and deliver energy on-site.
Further strategies include enhancing demand response programs—voluntary incentive initiatives that encourage customers to reduce or shift their electricity usage during peak demand periods—and promoting energy efficiency.
The ICF report indicates that these advancements could help fulfill over 10% of the national peak electricity demand by 2030.
Fortunately, various states, local governments, utilities, and grid operators are proactively seeking solutions to modernize the energy grid.
Indiana and Utah, for example, are currently advancing advanced transmission technologies (ATTs), with both states having enacted legislation to facilitate the deployment of these solutions for improved electricity delivery.
Researchers are also investigating flexible operating solutions for new data centers to alleviate stress on the grid.
As energy demand is projected to rise sharply in the U.S., it is crucial for governments and utilities to adopt effective and cost-efficient solutions promptly, thereby alleviating pressure on the grid while benefitting consumers.
