Global power demand is rising at the fastest pace in 15 years, driven by data centers, electrification, and industrialization, according to the International Energy Agency. The IEA estimates grid investment must increase by about 50% by 2030 from the current $400 billion per year to keep up. The United States set a record for electricity consumption last year and is forecast to set new highs this year and next.

Key Facts

The IEA estimates global grid investment must rise by about 50% by 2030 from the current $400 billion per year.
Global electricity demand will grow by more than 3.5% annually on average through the end of the decade, the fastest pace in 15 years.
U.S. electricity consumption set a record high last year and is forecast to set new all-time highs this year and next.
Wood Mackenzie forecasts 3.2% annual electricity sales growth in the U.S. through 2035, with two-thirds coming from data centers.
The Asia-Pacific region will account for nearly three-quarters of global electricity demand growth by 2035, according to Wood Mackenzie.

Demand Surge Drivers

The IEA attributes the accelerating demand to artificial intelligence infrastructure, data centers, advanced manufacturing, and electrification. In the United States, data center load is emerging as the dominant driver of long-term electricity growth, according to the U.S. Energy Information Administration. The West South Central region will account for nearly 20% of nationwide electricity sales growth in 2026 and almost 40% in 2027, the EIA forecasts. Europe's power demand is rising due to the same global factors plus the EU's decarbonization policies and renewables push.

Grid Investment Gap

The IEA calls insufficient grid capacity a critical constraint in many regions, exacerbating congestion and slowing deployment of new generation, storage, and consumer connections. Grid connection queues worldwide have reached record levels, according to the IEA. Wood Mackenzie analysts note that gas will meet 52% of increased U.S. power generation through 2035, but gas investment costs have hit a record high and turbine delivery bottlenecks complicate reliance on gas. The tension between speed to power and affordability is spurring reforms across regional U.S. power markets, though state policy responses remain fragmented.
