95% Clean Electricity by 2030

Commitment: “By 2030, at least 95% of GB electricity generation from clean sources; carbon intensity below 50 gCO₂e/kWh.”

Owner: DESNZ

Target date: 2030

Metric: Share of GB electricity from clean sources (%; annually reported); carbon intensity (gCO₂e/kWh; annually reported). Official statistics: DESNZ Clean Power 2030 Metrics.

Status: at-risk

Delivery history

• [2023] Baseline: Carbon intensity 171 gCO₂e/kWh. Clean sources generating well below 95% of demand.
• [December 2024] Clean Power 2030 Action Plan published. £40bn/year investment required (2025-2030). 739GW grid connection queue identified as primary bottleneck.
• [December 2025] Planning and Infrastructure Act receives Royal Assent — “first ready, first connected” grid reform enacted; LDES cap-and-floor mandated.
• [April 2026] Clean Power 2030 Metrics updated. Official statistics tracking underway.

Key dependencies

• Grid connection queue cleared and prioritised (80 critical projects)
• ~2× transmission infrastructure of past decade built by 2030
• Offshore wind: 3× current capacity (43-50 GW)
• Onshore wind: 2× current capacity (27-29 GW)
• Solar: 3× current capacity (45-47 GW)
• Sufficient skilled workforce (135,000-725,000 new clean energy jobs by 2030)
