The scale of AI data centers and their commensurate power needs are growing exponentially. By 2035, Deloitte estimates that power demand from AI data centers in the United States could grow more than thirtyfold, reaching 123 gigawatts, up from 4 gigawatts in 2024 (figure 1).1 AI data centers can require dramatically more energy per square foot than traditional data centers. For example, a five-acre data center augmenting central processing units with specialized graphics processing units might see its energy usage increase from 5 to 50 megawatts.2
The leading AI infrastructure developers that are scaling data center networks globally are known as hyperscalers. Each of the top three hyperscalers’ largest US data centers currently draw less than 500 megawatts (MW) of power but the largest data centers they are constructing or planning to build are more than double to quadruple the capacities of completed projects. The largest of these are expected to require up to 2,000 MW—that is, 2 gigawatts (GW) (figure 2).
However, even these capacities are modest compared to what is on its way. There are 50,000-acre data center campuses in early-stage phases, which could consume 5 GW3—the amount of power needed for five million residential homes, and more than the capacity of the largest existing nuclear or gas plants in the United States.4
AI data centers uniquely challenge grid operations because they can create large, concentrated clusters of 24/7 power demand. Some of the leading data center growth regions have experienced harmonic distortions, load relief warnings and near-miss incidents, and generation shutdowns.5
At the same time, the constellation of data center markets is changing. AI infrastructure development is spreading to more states and decentralizing as AI models are deployed closer to users to provide faster responses (figure 3).
Indeed, an April 2025 Deloitte survey of 120 US-based power company and data center executives shows that grid stress was the leading challenge for data center infrastructure development (see methodology). Seventy-nine percent of respondents said that AI will increase power demand through 2035 due to widespread adoption (figure 4).6
This is where the AI ambitions of the US government and industry come up against the grid’s capacity to power or to even interconnect data centers: There’s currently a seven-year wait on some requests for connection to the grid.7
There are other challenges, too.
The forecast ranges for AI data center demand vary widely, complicating efforts to build new generation while insulating residential customers from rate increases. Supply chain issues are also constraining energy companies and hyperscalers as manufacturers face sharp increases in demand for key infrastructure components. The overall uncertainty increases the risk of overbuilding or missing growth opportunities due to the inability to serve new customers.
To explore challenges such as these, and to identify opportunities and strategic approaches to building data center infrastructure, the Deloitte Center for Energy and Industrials conducted an AI infrastructure survey of executives from US-based data center and power companies. The results also support a set of strategic recommendations that can work together to close these gaps in the nation’s critical AI infrastructure.
Deloitte’s 2025 AI Infrastructure Survey included questions on infrastructure build-out challenges, resource mix to meet future energy consumption, workforce issues, AI workload planning, drivers of load growth, and investment priorities. The results were then divided based on respondent group to elucidate the differences between power companies and data center operators. The findings were further supplemented with secondary research and interviews with industry experts.
The results demonstrate that the primary challenge for data center infrastructure build-out is power and grid capacity, which 72% of all respondents consider to be very or extremely challenging (figure 5). In addition, companies surveyed express concern about supply chain disruptions (65%) and security (64%).
These constraints cited by survey respondents highlight seven key gaps in the build-out of data center infrastructure.
At the same time as data centers are pushing up peak demand, baseload generation is contracting, while new generation projects are stuck in increasingly long interconnection queues, 95% of which consist of renewables and storage (figure 6).8
These stuck projects are key to meeting the demand of hyperscalers, which have set clean energy goals and are the leading buyers of renewable power purchase agreements.9 Despite these targets, load growth over the past year in the top markets for data center growth has primarily been met with increased gas generation (figure 7).
The second greatest challenge among power company respondents is supply chain disruptions. Although the United States has enough manufacturing capacity to meet domestic demand for solar modules, demand is rising—and critical components are still imported and subject to tariffs (figure 8). Potential cost increases of steel, aluminum, copper, timber, and cement could also impact the build-out of power and gas infrastructure in the context of rising construction material costs, which have already jumped 40% over the past five years.10
Supply chain issues intersect with a top-3 challenge for the surveyed data center companies: Most power capacity development can take longer than data center build-outs, which can be completed in a year or two (figure 9). Gas power plant projects that have not already contracted equipment, for example, are not expected to become available until the 2030s.11
Renewables and battery storage can match this timeline and account for 92% of all planned generating capacity additions to the grid in 2025.12 But in some cases, the transmission needed to bring renewable capacity to load can take over a decade to build, and space constraints can limit the build-out of sufficient capacity next to data centers.
As AI capabilities grow, data centers should be secured against hackers who could subvert an AI model by gaining access to its weights, which govern model training and output. AI data centers can be especially vulnerable to supply chain attacks.13 Points of entry for cyber infringement can include servers, storage systems, cooling equipment, network gear, and other digital equipment that are shipped from multiple countries.14 Security of power supply is another concern for data center operators, as back-up generators have limited capacity.
The difficulty of securing permits and their varying timelines—ranging from months to years—can impact project schedules and inflate costs. It still takes more than two years to complete an environmental impact statement.15 The locus of authority for permitting mostly sits with the states, and over the past year, state-level restrictions have more than doubled overall (figure 10).16 Contested projects have grown 29%, and local restrictions on renewable projects have grown by 73%.17
Most respondents face the related challenges of competition with other industries and a shortage of skilled labor (figure 11). The latter is particularly acute for data center respondents, 63% of whom view it as the top challenge. For respondents from power companies, high turnover rates are the second greatest challenge.
Industry estimates of data center gas demand through 2030 range from 3 billion to 12 billion cubic feet per day18 amid a growing pipeline of planned natural gas plants. More than 99 GW of gas-fired capacity is planned across 38 states; yet, many top data center markets have constrained gas pipeline takeaway and transportation capacity (figure 12).
Despite shared industry challenges, data center and power companies surveyed diverge on how they experience these gaps and the relative importance of other issues.
While 60% of power companies surveyed believe residential affordability concerns will not constrain data center development, only 47% of data center operators share this view.
To close these gaps, the United States should develop additive infrastructure that can deliver efficiency, capacity, and flexibility. According to survey respondents, the most important strategies to overcome these challenges are technological innovation, regulatory changes, and more funding (figure 14).
According to 82% of those surveyed by Deloitte, a highly impactful means of closing the gaps is technological innovation, which can help build additive infrastructure by driving efficiency. This is also the top investment priority for 90% of data center respondents, followed by making infrastructure more intelligent (81%) and integrating renewable energy sources (66%).
Innovation in AI data center, chip, and grid efficiencies includes:
The perspectives of the surveyed executives from data center and power companies diverge the most with respect to the prospects for conventional and fusion nuclear energy. Most data center respondents believe conventional nuclear will play a greater role in meeting data center power consumption through 2035, versus a third of power companies. And 38% of data center respondents see a greater role for nuclear fusion, versus 17% of power companies. Similarly, half of data centers anticipate natural gas will play a greater role, compared to 37% of power companies. The same share of power companies sees a greater role for renewable natural gas, versus only 17% of data centers.
According to 76% of respondents in Deloitte's survey, regulatory change is highly impactful in addressing challenges to data center build-out. To add new capacity, the industry needs regulatory certainty built around system integration, stakeholder collaboration, and residential ratepayer protection.
To help expedite generation interconnection, the Federal Energy Regulatory Commission’s (FERC) Order 2023 kick-started reform by transitioning grid operators to “first-ready, first-served” cluster studies.29 While the order’s multiyear implementation is underway, several operators have taken more immediate action to address the risk of capacity shortfalls over the next year (see “Initiatives to speed interconnection”)
The focus on the load side should be on flexibility. To help expedite data center interconnection, regulatory reform could prioritize data centers that temporarily curtail load during grid emergencies or participate in demand response. Electric Reliability Council of Texas (ERCOT) has a Controllable Load Resource program that can interconnect large loads within two years.30 Grid operators could also offer expedited or joint interconnection to data centers that build their own on-site generation. New compensation mechanisms could incentivize these colocated project developers to invest in generation sized to exceed load and supply the grid during peak demand.
Load interconnection challenges have contributed to interest in bypassing interconnection queues and reducing transmission costs by colocating data centers with existing power plants. This type of colocation has raised broader regulatory questions about transmission service use, transmission cost calculation, and implications for reliability and customer rates. FERC and ERCOT rulemaking underway may help create more regulatory certainty to enable colocation-based business model innovation.
Grid operators are launching one-time mechanisms to bypass queues. These include PJM Interconnection’s emergency Reliability Resource Initiative, which can expedite the interconnection of firm generation by 18 months to meet resource adequacy needs.31 Natural gas-fired generation accounted for more than two-thirds of the 11.8 GW of capacity that PJM selected from 94 new and uprated battery, gas, and nuclear applicants.32 PJM also removed Surplus Interconnection Service barriers that could enable an equal capacity to connect to its grid within the next two years.33
Meanwhile, Midcontinent Independent System Operator (MISO) and Southwest Power Pool (SPP) have developed Expedited Resource Adequacy Studies (ERAS) proposals for projects with commercial operation dates within the next two to three years.34 MISO plans to consider these quarterly and grant interconnection agreements within 90 days.35 SPP aims to further reduce study time and costs through consolidated generation, load, and transmission planning by 2027.36
Beyond interconnection of generation and load, system integration can extend to regulatory certainty around interregional transmission. FERC Order 1920 laid the groundwork for transmission planning to meet load growth, including identification and evaluation of interregional transmission.37 Establishing a minimum interregional transmission capability of up to 30% of a region’s peak load could unlock 149 GW in capacity (figure 17).
2. Stakeholder cooperation: Partnership between power companies, data centers, and grid operators can help advance the regulatory process. For example, in May 2025, a public utility commission approved the first clean transition tariff that a hyperscaler, a utility, and a renewable energy developer crafted together to jumpstart the deployment of new clean energy resources.38 The largest US grid operator is also partnering with a hyperscaler in a groundbreaking use of AI to accelerate the interconnection process.39 According to 78% of data center companies and 67% of power companies surveyed by Deloitte, cooperation between data center operators and utilities on infrastructure development and cost allocation is effective, but only 15% of data center executives and 8% of power company executives describe it as highly effective. The data center respondents see partnering with utilities to secure reliable grid power as the top strategy to meet the energy demand for their operations (63%).
3. Residential ratepayer insulation: Regulatory mechanisms can help firewall residential customers from costs associated with serving data center loads. These include creating a separate rate class for data centers and implementing tariffs with monthly demand and minimum charges based on contracted capacity, upfront payments, long contract terms, and exit fees.
Computational task mobility can unlock a third aspect of additive infrastructure: flexibility. Large, inflexible loads can require major, costly, and time-consuming infrastructure upgrades because they add to the power system’s peak demand. However, if data centers could operate with some flexibility during periods of peak demand, they could be considered grid assets and may be able to avoid the need for capacity addition upgrades altogether, thereby enabling rapid connection. Task mobility involves shifting flexible computing tasks to different times of day or data centers in response to grid conditions. If AI data centers agreed to curtail just 1% of their load, they could increase the grid’s ability to interconnect them. A study found that grid operators could add 126 GW in new load with minimal grid capacity expansion if average annual load was curtailed at a rate of 1% (figure 18). Among Deloitte’s survey respondents, 68% of industry executives believe data center demand flexibility will become an acceptable tradeoff to secure speed to market.
Developing additive infrastructure will require massive funding across all of the industries involved. The impact of AI data center development is already becoming more apparent in investment discussions. Mentions of “data center” in investor earnings calls transcripts in both the manufacturing and energy sectors grew fivefold from 997 in 2023 to a record high 5,402 in 2024.40 Data centers have thereby gained importance to long-term strategy and investments, opening the door to new funding opportunities. Among the power company and data center executives surveyed by Deloitte, 67% believe funding to be a key to closing AI infrastructure gaps. This is already well underway.
In 2024, private investment in US data centers reached a record high.41
Meanwhile, electric and gas utilities are forecasting a record increase in capex. It is expected to jump 22% year over year to US$212 billion in 2025 across 47 utilities—a sharp rise from the 7.6% CAGR over the past decade (Figure 19).42
In 2024, capital light hyperscalers surpassed capital-intensive utilities in capex, a trend that is expected to continue.43 Eight hyperscalers expect a 44% year-over-year increase to US$371 billion in 2025 for AI data centers and computing resources.44
The changing scope and scale of infrastructure development have likewise increased the investment stakes of building out capacity for data centers, power generation, and manufacturing to trillion-dollar levels.
Electric and gas utility capex is expected to surpass US$1 trillion cumulatively within the next five years (2025–2029) for the 47 biggest investor-owned utilities. For the hyperscalers, reaching the trillion-dollar threshold is expected in only three years, with spending projections reaching half a trillion dollars annually by the early 2030s.45 And for data centers more broadly, spending could reach a trillion dollars within three years.46
The tech industry has also announced plans to invest more than a trillion dollars in US manufacturing of AI supercomputers, chips, and servers over the next four years.47
The new level of funding reflects confidence that trillion-dollar AI applications and returns will materialize. Fears that cheaper models could undermine hyperscalers’ business model have sparked market volatility. But they have not impacted hyperscaler AI chip purchases and capex forecasts.48 Rather, hyperscalers have shifted investment from AI training towards inference.49
New business models can capitalize on technological, regulatory, computational task mobility, and funding innovation to build additive infrastructure that can unlock efficiency, capacity, and flexibility. Business models fusing AI data center and power infrastructure development could bring capacity online faster while maintaining resource adequacy and affordability. Colocating new load with commensurate new capacity at a single point of interconnection could be grid supportive, helping to avoid the need to build more transmission, sharing supply-constrained power equipment, and enabling the injection of surplus energy onto the grid during periods of peak demand.
One approach is to redevelop the sites of closed plants into data center campuses powered by higher capacity generation. For example, in Pennsylvania’s largest capital investment (US$10 billion), the state’s largest retired coal plant is converting into the largest gas plant in the United States. The conversion will more than double the plant’s capacity to meet demand for multiple AI data centers. By leveraging existing grid infrastructure, the data center campus is expected to start operations by 2027.50
Another option could be to tap existing underused surplus interconnection, whereby new generation can connect at the site of existing generators in under a year, compared to more than five years for standard interconnection.51A recent study found that fossil fuel plants could cost-effectively share grid access with 800 GW of renewables and double US generation capacity (figure 20).52 Another study found that 160 peakers and load-following gas plants have sufficient idle capacity to serve as backup generators for data centers colocated with new renewable and storage capacity; combined, these could meet approximately 50 GW of AI load.53
For hyperscalers seeking entirely renewable generation, the fused infrastructure might need to be more fully integrated with the grid, providing surplus low-cost clean energy to the grid while drawing on the grid for backup. One hyperscaler is partnering with a renewable developer and private equity to invest US$20 billion in developing an energy park with colocated load, generation, and storage to be operational by 2026.54
Achieving the new scope, scale, stakes, and speed of AI infrastructure development can be a complex undertaking. However, technological, regulatory, funding, and business model innovation can help unlock additive infrastructure for artificial intelligence, or “AI for AI.” Additive infrastructure can bring efficiency, capacity, and flexibility to powering AI. But to achieve these ends, power companies and data centers should consider partnering both with each other and across industries including real estate, investment funds, utilities, power and gas companies, renewable developers, construction companies, and manufacturers of key components.
Given the complexities, partnerships among these industry players are expected to look very different from the ones of the past. If they fail, power and grid capacity constraints could hamstring AI advancement. Power companies could miss an opportunity to expand and modernize the grid. And domestic manufacturing growth in some sectors could stall and lose an edge. These developments could jeopardize US economic and geopolitical leadership. Indeed, staking an infrastructural lead in powering AI may now be a matter of competitiveness and even national security.
The Deloitte Center for Energy and Industrials conducted a survey in April 2025 to identify the challenges, opportunities, and strategies of US data centers and power companies, and to benchmark their infrastructure development. The survey sample of 120 respondents included 60 data center executives and 60 power company executives, who responded to questions on infrastructure build-out challenges, resource mix to meet future energy consumption, workforce issues, AI workload planning, drivers of load growth, and investment priorities.
