Commercial electricity sales in Virginia have surged dramatically, increasing by nearly 30.0 million megawatthours (MWh) between 2019 and 2025. This growth rate significantly outpaces that of any other state, with the exception of Texas, which is considerably larger, according to the U.S. Energy Information Administration's (EIA) Annual Electric Power Industry Report. The primary drivers behind this surge in electricity consumption are a substantial concentration of data centers within the state, coupled with the increasing adoption of electric vehicles and broader building electrification efforts.
Electricity sales, as defined by the EIA, represent the energy delivered from load-serving entities (LSEs)—predominantly utilities—to end consumers. These LSEs are responsible for maintaining adequate resources and reserves to meet fluctuating customer demand, which can experience significant spikes hourly, daily, or seasonally. This challenge is further compounded by a consistent rise in energy needs across their service territories and the increasing frequency of extreme weather events.
Peak load, a critical metric representing the highest demand for electricity within a specific period, is a key indicator for grid operators. This snapshot, measured in megawatts (MW), captures the instantaneous maximum load, even if it occurs for a brief duration, such as 15 minutes. Understanding and managing these peak loads are essential for ensuring grid stability and reliability, especially as demand patterns evolve.
Earlier this year, PJM Interconnection (PJM), the regional transmission organization responsible for operating the electrical grid across 13 mid-Atlantic states and the District of Columbia, released its 2026 Long-Term Load Forecast Report. This report provides projections for electricity demand across its various transmission zones. PJM anticipates that the Dominion zone, which encompasses Virginia, will witness the most significant absolute increase in summer peak demand between 2026 and 2030. This projection is largely driven by the escalating demand from data centers.
The Dominion zone is already home to the world's largest concentration of data centers. This area has become a prime location for such facilities due to a combination of factors, including extensive fiber optic connectivity, available land, and robust power infrastructure. The continued expansion of these digital hubs directly translates into higher electricity consumption and increased strain on the power grid during peak demand periods.
Data from the EIA's Hourly Electric Grid Monitor and PJM's load forecast reports illustrate the escalating demand. In 2025, the summer peak load in PJM's Dominion zone reached 23,905 MW, a 23% increase compared to 2019. Similarly, the winter peak load for the 2025-26 season stood at 25,413 MW, marking a substantial 45% rise from the 2019-20 winter season. These figures underscore the rapid and significant growth in electricity consumption within the region.
Looking ahead, PJM forecasts that peak summer load in the Dominion zone will grow at an average annual rate of 5.4% over the next decade. While this represents a slight downward revision from its previous projection of 6.3% in the 2025 forecast, it still indicates a sustained and considerable increase in demand. The EIA's analysis of hourly load data further highlights this trend, showing that a vast majority of the top 50 peak hourly loads in the Dominion zone occurred in either 2024 or 2025, emphasizing the recent acceleration of demand.
In response to these growing challenges, utilities and other market participants are actively implementing strategies to manage peak demand. These measures include demand response programs, the deployment of energy storage solutions, upgrades to facilities with available interconnection capacity, and investments in infrastructure enhancements to bolster reliability. Furthermore, efforts are underway to improve load forecasting capabilities, particularly for data center demand, given the rapid pace of deployment and evolving technologies in this sector. The effective management of these trends is crucial for ensuring a stable and sufficient electricity supply for Virginia and the broader PJM region.
