Rationale

Full access

My most likely prediction for the IEA forecast for global electricity demand growth in 2027 in its next annual Electricity Market Report is 3.78% because robust structural electrification, accelerating GDP growth, and data center expansion will maintain high demand momentum near the IEA's prior 3.8% benchmark, slightly tempered by fuel supply disruptions from Middle Eastern LNG curtailments.

Forecast record

Question context

In its July 2026 Electricity Mid-Year Update, the International Energy Agency (IEA) projected that global electricity demand will grow by 3.8% in 2027, accelerating from an expected 3.6% in 2026. This growth is anticipated to be driven by industrial expansion, electric vehicles, data centers, and increased cooling needs exacerbated by a strengthening El Niño. However, geopolitical supply shocks, such as LNG disruptions in the Strait of Hormuz due to regional conflicts, are adding price volatility and could weigh on demand in price-sensitive emerging markets. The IEA typically publishes its flagship annual Electricity Market Report in January, which will provide updated projections for the coming year.

Resolution criteria

This question will resolve based on the IEA's forecast for global electricity demand growth for the year 2027, as published in its next major Electricity 2027 report (typically released in January). Use the headline percentage growth (year-on-year) for global electricity demand/consumption in 2027. The value should be expressed as a percentage (e.g., 3.8 for 3.8%).

If the IEA does not publish a new Electricity Market Report or equivalent global electricity forecast by the end of February 2027, the question will resolve based on the next available official IEA global electricity demand forecast for 2027 published before June 30, 2027. If no forecast for 2027 is published by that date, the question will be annulled.
