Global Electricity Demand to 2030: Growth, Renewables & Grid Investment

Global electricity demand is poised for significant growth through 2030, increasing by more than 3.5 percent annually. This surge is driven by the increasing electrification of industry, the adoption of electric vehicles, and the expanding needs of data centers, according to a new report by the International Energy Agency (IEA).

The Changing Energy Landscape

This projected increase in demand is expected to outpace overall energy growth, as more sectors transition to electricity. Rising industrial use, greater demand for cooling, and the expansion of artificial intelligence are all contributing factors. Even advanced economies, which experienced stagnation in electricity consumption for over a decade, are now seeing renewed increases.

Did You Know? More than 2,500 gigawatts of renewable, storage, and large electricity user projects are currently stalled in grid connection queues worldwide.

A Shift in Supply

The report indicates a significant shift in electricity generation sources. Renewables are on track to surpass coal, fueled by record deployment of solar photovoltaic capacity. Nuclear power generation has also reached a new high. Combined, renewables and nuclear are projected to supply 50 percent of global electricity by the end of the decade, a rise from 42 percent today.

Natural gas is also expected to play a growing role, particularly in the United States and parts of the Middle East, where a shift from oil to gas is underway. Conversely, coal-fired generation is forecast to decline globally, returning to 2021 levels by 2030. This shift is expected to keep global carbon dioxide emissions from electricity generation relatively flat.

Expert Insight: The projected growth in electricity demand, coupled with the shift towards renewable sources, highlights the critical need for substantial investment in grid infrastructure and system flexibility to ensure a reliable and secure energy supply.

Infrastructure Challenges and Investment Needs

The IEA warns that current electricity infrastructure is facing increasing pressure. The growth in demand, coupled with a more weather-dependent generation mix, necessitates rapid expansion of power grids and increased system flexibility. IEA Director of Energy Markets and Security Keisuke Sadamori stated that annual investment in power grids will need to increase by around 50 percent by 2030 to meet rising demand.

Deploying grid-enhancing technologies and implementing regulatory reforms could unlock up to 1,600 gigawatts of stalled projects. Utility-scale battery storage is emerging as a key source of short-term flexibility, with growth observed in markets like California, Germany, Texas, South Australia, and the United Kingdom.
