Location- and market-based electricity grid trends for the United Kingdom, plus other factors as we expand coverage.
Utilities · kWh
UK is committed to reducing GHG emissions to 80% below 1990 levels by 2050. A key contribution to this target is the Net Zero Strategy to deliver on the government’s target to achieve 100% renewable electricity by 2050.

UK’s utilities_electricity_grid residual factor could follow a sharper decarbonisation path than the CER baseline suggests. Ember’s 2025 forecast envisions the residual market-based factor falling from 0.92 in 2025 to 0.75 by 2030 (Ember, 2025 Forecast), a roughly 19% reduction. This contrasts with CER’s projection of a gradual rise to about 0.98 by 2030 (CER, 2025 Forecast). The drivers underpinning a lower residual factor include: accelerated deployment of wind/solar and storage with ongoing coal retirements (AEMO, 2024); strengthened Safeguard Mechanism reforms tightening baselines for large emitters to accelerate abatement (DCCEEW, 2023–2025); rapid growth of corporate PPAs—around 60% of capacity contracted by 2025—locking in low-emission supply (Briggs, BRCA, 2025); and wholesale-market reforms and transmission investments that embed renewables into the market (AEMO, 2024). Together, these factors support a stronger decarbonization trajectory across uk-england, uk-scotland, uk-wales, and uk-northernireland.
