Grid Investment Needs $200 Billion More Annually or AI Stalls

Annual grid investment must climb by roughly $200 billion—a 50% jump from today's $400 billion—to meet forecasted electricity demand through 2030, according to the IEA's Electricity 2026 report released in February. Global electricity consumption growth is expected to average 3.6% annually over the next five years, but the wires can't keep up. More than 2,500 gigawatts of projects—renewables, storage, and data centers—are stalled in grid connection queues worldwide, waiting years just to plug in.

The market is pricing data centers and AI as the next decade's trade. It should be pricing grid bankruptcies and stranded megawatts. U.S. data center power demand alone could hit 35-45 GW by 2030—roughly double 2024 levels. A single AI task uses up to 1,000 times more electricity than a traditional web search, and Samantha Dart, Goldman Sachs' co-head of global commodities research, warned in January that the U.S. could face a power crunch by 2030 at current interconnection rates, and if grid constraints go unaddressed, China could pull ahead in the AI race.

As of 2026, the U.S. interconnection queue has swelled to a 2,600 GW backlog, with median wait times approaching five years and some data center projects facing potential delays of up to 12 years. Over 2,060 GW of generation and storage capacity were actively seeking grid connection at the end of 2025, but most projects that apply for interconnection are ultimately withdrawn, and those that are built are taking longer on average to complete. In PJM's reopened queue alone, natural gas projects dominate at 106 GW, followed by storage at 67 GW, nuclear at 17 GW, and solar at 15 GW. Power availability—not capital—is now the primary constraint on data center development, with electrical grid interconnections often taking up to four years.

This isn't 2015, when efficiency gains masked flat demand in advanced economies. Electricity demand in advanced economies is rising again after 15 years of stagnation, with advanced economies accounting for almost 20% of additional global demand in 2025, up from 10% in 2020. U.S. electricity demand rose by 2.1% in 2025 and is expected to grow nearly 2% annually through 2030, with the rapid expansion of data centers driving half of the increase. Consensus thinks this is renewable-driven load growth. Wrong. It's concentrated industrial electrification and AI compute hitting grids designed for residential air conditioning peaks.

The mismatch is structural. Deploying grid-enhancing technologies and updating grid connection rules could allow up to 1,600 GW of queued projects to connect in the near term, making better use of existing infrastructure. But while IT hardware supply chains can scale production within 12-24 months, upgrading national power grids and manufacturing heavy electrical equipment like high-voltage transformers involves multi-year, and in some cases, decadal timelines.

Watch three things:

• Behind-the-meter deals: Developers are prioritizing "will-serve" contracts for transmission capacity by a date certain, or air permits and fuel supply for bring-your-own-power solutions, with natural gas air permits a major gating issue as gas is expected to dominate data center power over the next five years.
• Interconnection reform velocity: The median duration from interconnection request to commercial operation has doubled from under 2 years for projects built in 2000-2007 to over 4 years for those built in 2018-2024. Any RTO that cuts this materially reshapes regional competitiveness.
• Regional power price divergence: U.S. residential electricity prices average 18.2 cents per kilowatt-hour in 2026, up nearly 5% from 2025, with regions along the East Coast expecting average annual growth ranging from 5% to 7% between 2024 and 2027 due to higher fuel prices and expenses for bolstering transmission against extreme weather and rising power demand.
