Key facts
- Global power demand is rising faster than grids can handle.
- Data centers are a primary driver of increased electricity consumption.
- US electricity demand set a record last year and is projected to continue rising.
- The Asia-Pacific region is expected to lead global power demand growth.
- Annual global grid investment needs to increase by 50% by 2030 to meet demand.
- Grid connection queues have reached record levels globally.
Global power demand is experiencing a resurgence not seen in decades, driven by factors such as data centers, electrification, and industrialization, according to the International Energy Agency (IEA) and analysts at Wood Mackenzie. This phenomenon, termed the "Age of Electricity," is reshaping power markets worldwide and presenting significant challenges for grid infrastructure.
In the United States, electricity consumption reached a new record last year and is projected to set further records in the coming years, largely due to the burgeoning AI boom and its associated data centers. The U.S. Energy Information Administration (EIA) forecasts that data center load will be the primary driver of long-term U.S. electricity growth. Despite some recent pauses in new data center connections in Texas, the West South Central region is still expected to contribute significantly to nationwide growth in electricity sales.
Wood Mackenzie analysts predict an average annual electricity sales growth of 3.2% in the U.S. through 2035, with data centers accounting for two-thirds of this increase. While natural gas is expected to meet 52% of the additional power generation needs, rising investment costs and delivery bottlenecks for gas turbines are complicating a heavy reliance on this energy source. Analysts highlight the tension between the need for rapid power generation and the risk of stranded assets, noting that fragmented state policies in the U.S. are hindering solutions.
Europe is also witnessing rising power demand, fueled by the same global trends as well as the European Union's decarbonization policies and its push for renewables to enhance energy security. Meanwhile, the Asia-Pacific region is anticipated to experience the most substantial power demand growth globally, driven by industrialization, economic expansion, and urbanization in countries like China, India, and Southeast Asia. Wood Mackenzie estimates that APAC will account for nearly three-quarters of global demand growth by 2035.
A critical common challenge across all regions is the inadequacy of existing grid infrastructure to handle the surge in electricity loads. The IEA projects global power demand to grow by over 3.5% annually on average through the end of the decade. Developers of new power capacity, particularly renewables and natural gas, are facing significant constraints in connecting to the grid. The agency estimates that current annual global grid investments of approximately $400 billion need to increase by about 50% by 2030 to meet projected demand. The IEA notes that a lack of grid capacity is a major bottleneck, leading to increased congestion and slowing the deployment of new generation, storage, and demand-side resources, with grid connection queues reaching record levels worldwide.
