Power Has Become the New AI Bottleneck
For years, discussions about artificial intelligence focused on GPUs, semiconductors, cloud infrastructure, and computing power. In 2026, that conversation has changed dramatically.
According to Ditlev Engel, CEO of Energy at DNV, writing in the World Economic Forum article "If Electricity and Data Are the New Oil, Is Grid Connectivity the Strategic Bottleneck in the AI Transformation?" (May 18, 2026), AI infrastructure investment is growing faster than electrical grids can support.
His central argument is simple but profound:
Grid connectivity is increasingly becoming the factor that determines which AI projects move forward and which remain on paper.
While hyperscale AI campuses can often be designed and built within two to three years, obtaining reliable power connections frequently takes four to ten years in many regions.
As a result, electricity infrastructure—not chips, capital, or software—is emerging as the dominant constraint on AI expansion.

AI Electricity Demand Is Growing Faster Than Utilities Expected
Virtually every major forecast released in 2025 and 2026 points to one conclusion: AI is creating unprecedented growth in electricity demand.
The International Energy Agency's landmark report, "Energy and AI," projects that global data center electricity consumption will rise from approximately 415 TWh in 2024 to nearly 945 TWh by 2030.
The IEA estimates annual growth of roughly 15%, which is more than four times faster than overall global electricity demand growth.
Even more important is where that growth originates.
According to the agency, AI-accelerated servers—including GPU clusters used for training and inference—are expected to griow approximately 30% annually and account for nearly half of future data center electricity demand growth.
The United States and China alone are expected to contribute roughly 80% of total global demand growth through 2030.
Goldman Sachs: U.S. Data Center Demand Could Double in Two Years
One of the most cited forecasts in 2026 comes from Goldman Sachs Commodities Research.
In the report "US Data Center Power Demand Projected to Double by 2027," analysts Hongcen Wei, Daan Struyven, and Samantha Dart forecast:
- 31 GW in 2025
- 41 GW in 2026
- 66 GW in 2027
This would represent more than a doubling of U.S. data center power demand within just two years.
The researchers attribute this surge to aggressive AI infrastructure deployment and hyperscaler expansion.
Their analysis incorporates:
- Construction progress
- Permitting activity
- Utility planning data
- Facility-level development tracking
- Satellite imagery
Goldman Sachs also notes that U.S. data center capacity could exceed 95 GW by the end of 2027, highlighting the extraordinary scale of planned AI infrastructure investment.

Why Grid Connectivity Has Become the Industry's Biggest Problem
The challenge is not simply generating electricity.
The challenge is delivering it.
According to both the World Economic Forum/DNV analysis and the International Energy Agency, transmission infrastructure is struggling to keep pace with AI-driven demand growth.
Developers are increasingly encountering:
- Multi-year interconnection queues
- Transmission congestion
- Substation shortages
- Transformer shortages
- Utility approval delays
- Local permitting barriers
The World Economic Forum notes that new AI facilities often require power connections far beyond what existing local infrastructure was designed to support.
Many projects are reaching construction readiness before power infrastructure is available.
This reverses decades of traditional infrastructure planning, where power availability was usually assumed rather than questioned.
What Is Limiting AI Growth in 2026?
Transformer Shortages Are Delaying AI Projects Nationwide
One of the most widely discussed bottlenecks in 2026 is the shortage of high-voltage transformers.
A detailed analysis published by Tech Investments in May 2026 titled "Power Bottlenecks & The AI Data Center" highlighted the issue using data from Sightline Climate.
The report noted that:
- Approximately 12 GW of U.S. data center capacity was announced for 2026.
- Only around 5 GW was actually under construction.
- Around 11 GW remained in the announcement stage with limited physical progress.
The article cites transformer lead times that have expanded dramatically.
Before 2020:
- Typical lead times were roughly 24–30 months.
In 2026:
- Lead times often extend to 3–5 years or longer.
The implication is significant.
AI companies may have:
- Land
- Financing
- GPUs
- Construction permits
Yet still be unable to operate because critical electrical equipment has not arrived.

Interconnection Queues Are Becoming a Strategic Risk
The Center for Strategic and International Studies (CSIS), World Economic Forum, and multiple utility operators now describe electricity access as a strategic issue for AI competitiveness.
In major U.S. markets, grid connection timelines can exceed seven years.
Northern Virginia—often called the world's largest data center market—has become a symbol of this challenge.
Demand growth is occurring faster than transmission and generation infrastructure can be expanded.
This phenomenon is not limited to America.
Europe, Southeast Asia, and several emerging AI markets face similar constraints.
The issue is becoming global.
Capacity Growth Is Outpacing Grid Expansion
Research from Bloom Energy's 2026 Data Center Power Report illustrates the scale of the challenge.
The company estimates:
- U.S. IT load capacity near 80 GW in 2025
- Approximately 150 GW by 2028
The report also predicts:
- One in five AI campuses could reach gigawatt scale by 2030
- One in three could reach gigawatt scale by 2035
These are unprecedented infrastructure requirements.
For perspective, a single gigawatt-scale AI campus can rival the electricity demand of a major metropolitan area.
Utilities must therefore build:
- New transmission lines
- New substations
- Additional generation capacity
- Backup systems
- Grid reinforcement infrastructure
all while maintaining reliability for existing customers.
EPRI Warns About Growing Grid Pressure
The Electric Power Research Institute (EPRI) intensified concerns in its 2026 report "Powering Intelligence."
The organization estimates that data centers could account for:
- 9% to 17% of U.S. electricity generation by 2030
Virginia faces even greater pressure.
EPRI projects that data centers could eventually consume between:
- 39%
- 57%
of the state's electricity supply.
These numbers explain why regulators and utilities increasingly view AI infrastructure as a system-wide planning challenge rather than a niche technology issue.
The Rise of "Bring Your Own Power" (BYOP)
Because utilities cannot always deliver power quickly enough, developers are increasingly pursuing alternative solutions.
A major trend identified by HSBC, Bloom Energy, and industry analysts is the emergence of:
Bring Your Own Power (BYOP)
Rather than waiting years for grid connections, companies deploy:
- On-site natural gas generation
- Fuel cells
- Microgrids
- Battery systems
- Hybrid power solutions
The goal is straightforward:
Operate immediately while grid infrastructure catches up.
Some operators now plan to remain partially or entirely independent of the grid indefinitely.
Fuel Cells Are Emerging as a Fast-Track Solution
The Tech Investments analysis highlights growing interest in fuel-cell-based power systems.
Bloom Energy has become one of the most visible players in this space.
According to company disclosures discussed in the report:
- Oracle's Project Jupiter selected Bloom Energy systems.
- The project could deploy up to 2.85 GW of power capacity.
- The facility is designed to operate as an islanded microgrid.
The attraction is speed.
Traditional utility-scale solutions often require:
- Transformer procurement
- Transmission upgrades
- Multi-year approvals
Fuel-cell systems can often be deployed significantly faster.
Industry leaders increasingly describe "time-to-power" as the most important competitive metric in AI infrastructure development.
Regional Winners and Losers Are Emerging
The AI infrastructure boom is reshaping geography.
Regions Under Pressure
According to Goldman Sachs Research:
- Mid-Atlantic
- Mid-Continent
- Northwest
face elevated reliability risks because planned demand growth exceeds expected generation additions.
Regions Gaining Momentum
Texas and Georgia are increasingly attractive because:
- Additional generation is being built
- Interconnection opportunities remain stronger
- Land availability is greater
- Regulatory processes are often faster
Bloom Energy and other analysts also point to broader migration toward power-rich locations.
The new competitive advantage is increasingly:
speed-to-power rather than proximity-to-users.
| Region | Power Availability | Grid Risk | Data Center Growth |
|---|---|---|---|
| Northern Virginia | Low | Extreme | Very High |
| Mid-Atlantic | Moderate | High | High |
| Texas | Strong | Low | Very High |
| Georgia | Strong | Low | High |
| Europe | Moderate | Medium | High |
| Southeast Asia | Moderate | High | Very High |
Gartner: AI Servers Are About to Overtake Traditional Servers
Another important development comes from Gartner's June 2026 forecast.
The research firm estimates:
- Global data center power demand grows approximately 26% in 2026.
- AI-optimized servers account for roughly 31% of total consumption in 2026.
- AI servers surpass conventional servers in electricity consumption during 2027.
This transition matters because AI infrastructure has very different operating characteristics.
AI facilities typically feature:
- Higher rack densities
- Larger power requirements
- Greater cooling needs
- Less interruptibility
These characteristics place additional pressure on grid operators.
The Industry Is Moving From a Chip Constraint to a Power Constraint
Perhaps the most important insight from 2026 research is that AI infrastructure constraints have shifted.
How The Industry Is Solving AI Power Bottlenecks
In 2023 and 2024, discussions focused on:
- GPU shortages
- Semiconductor manufacturing
- AI model development
By 2026, leading organizations including:
- International Energy Agency
- World Economic Forum
- Goldman Sachs Research
- EPRI
- Gartner
- CSIS
- Bloom Energy
- Lawrence Berkeley National Laboratory
are increasingly focused on power availability.
The question is no longer whether AI demand exists.
The question is whether enough electricity infrastructure can be built quickly enough to support it.
For data center developers, hyperscalers, utilities, investors, and policymakers, the defining challenge of 2026 is not computing capacity—it is energy capacity.
