IEA Sees Faster Global Power Demand Growth Through 2027
A Reuters report via BOE Report details a new IEA Electricity Mid-Year Update showing global power demand growth accelerating to 3.6% in 2026 and 3.8% in 2027, up from 3% in 2025. The agency points to industrial expansion, data centers, EVs, heat pumps, and rising air conditioning use as the main drivers. China leads demand growth at 5.5% in 2026, followed by India at 7%, while the U.S. and European Union grow near 2% each. Renewables are expected to overtake coal as the world’s largest electricity source in 2026 after reaching near parity in 2025, with solar and wind supply climbing from 17% in 2025 to 21% by 2027. Solar is projected to overtake wind as the second-largest renewable source behind hydropower. Coal generation is still expected to rise 1.4% in 2026 due to higher gas prices and renewable curtailment. The IEA also noted that Middle East energy shocks have raised generation costs and volatility without derailing overall demand growth, and that LNG supply disruptions tied to the U.S.-Israeli war on Iran are hitting price-sensitive markets like Pakistan and Bangladesh.
What It Means for Subcontractors
- Electrical contractors and E&I crews serving data center and industrial expansion projects in the U.S. should expect steady, not explosive, load growth given the roughly 2% U.S. demand forecast for 2026, slower than China’s 5.5% or India’s 7%.
- Solar EPC and O&M firms have a growth case to point to: solar is set to overtake wind as the second-largest renewable source by 2027, supporting continued utility-scale and distribution-tied solar build-out bids.
- Transmission and substation contractors should track utility integrated resource plans now, since renewables overtaking coal as the top global generation source in 2026 signals sustained grid interconnection and upgrade work through 2027.
