Data Center Electricity Demand Set for Unprecedented Growth
Hyperscale data centers in the United States are projected to consume 22 percent more grid power by the end of 2025 compared to current levels, according to recent analysis from 451 Research, which is now part of S&P Global. The research suggests this represents just the beginning of a much larger trend, with electricity requirements potentially nearly tripling by the end of the decade.

AI Infrastructure Boom Driving Power Consumption
Industry analysts suggest the rapid expansion of data center capacity is largely fueled by escalating demand for advanced machine learning models and artificial intelligence systems. These technologies require highly configured servers packed with power-intensive GPUs for development and training operations. The substantial power and cooling infrastructure needed for these operations means companies often find it more practical to construct new facilities rather than retrofit existing ones.
According to the report, utility power dedicated to American data centers is estimated to jump to 61.8 gigawatts by the end of this year, representing an increase of 11.3 GW. Researchers calculate this will rise again to 75.8 GW in 2026, then 108 GW in 2028, before potentially reaching 134.4 GW by 2030. These projections specifically exclude enterprise-owned facilities, focusing instead on hyperscale operators including Amazon, Apple, Google, Meta Platforms, and Microsoft, along with leased and cryptocurrency mining sites.

Massive Capital Investments Fuel Expansion
The dramatic increase in power requirements corresponds with unprecedented levels of investment in new data center infrastructure from technology giants. Sources indicate Amazon expects to spend approximately $100 billion on capital expenditure projects this year, while Microsoft is investing $80 billion in infrastructure development. Meta reportedly aims for $66-72 billion in infrastructure spending, and Google has increased its 2025 capex projection to $85 billion.
Grid Management Challenges Emerging
The research includes cautions about potential overestimation of actual growth rates, pointing to recent developments in Ohio where a power company implemented specific tariffs for data centers. These regulations require large data center customers connecting to AEP Ohio’s grid to be responsible for at least 85 percent of their subscribed energy regardless of actual usage. Following this policy change, interconnection requests reportedly dropped to 13 GW across 36 sites, down from more than 30 GW previously.
Analysts suggest this reduction indicates some operators may have inflated their projected energy requirements, potentially leading utility companies to overinvest in grid infrastructure. The report also notes that some developers may duplicate connection requests across different jurisdictions, further complicating accurate demand forecasting.
Regional Concentration and Emerging Markets
Research identifies Virginia and Texas as the states with the highest data center energy requirements this year. Virginia’s data center load, comprising both leased and hyperscale facilities, is forecast to reach 12.1 GW in 2025, up from 9.3 GW last year. In Texas, demand driven by cryptomining and leased capacity is slated to hit 9.7 GW this year, increasing from less than 8 GW previously.
The search for optimal locations is reportedly leading data center operators to explore emerging markets including Idaho, Louisiana, Oklahoma, and smaller cities in West Texas. According to the analysis, companies are particularly interested in areas with “stranded power” and alternative energy generation opportunities.
Alternative Power Solutions Gaining Traction
Given existing grid limitations, the report states that on-site power generation systems are increasingly finding favor among data center operators. These solutions may serve as standby options until grid connections with sufficient load capacity become available. Among the alternatives being considered are retired nuclear assets, gas-fired generation, battery storage, fuel cells, renewables, and various hybrid combinations.
The comprehensive research from S&P Global highlights the significant challenges utilities and technology companies face in balancing infrastructure expansion with reliable power delivery. As the industry continues to evolve, technology developments from companies like Microsoft and innovations from organizations including Mozilla will likely influence future energy requirements, while regulatory considerations highlighted by international financial authorities may shape investment patterns in the coming years.
