GB Clean Power Action Plan 2030: Year one status review

In 2024, the UK government set out an ambitious target: to deliver enough zero-carbon power to meet Great Britain’s annual electricity demand by 2030. One year into this journey, Montel's latest analysis delivers a clear-eyed review of where progress is being made and where it’s falling short.

• Solar on track
  Solar capacity is growing at pace, on course to triple 2023 levels by 2030, with year-on-year buildout increasing by 20% and strong deployment both at scale and behind the meter.

• Offshore wind under pressure
  Forecasts suggest GB will fall ~9 GW short of its 43 GW offshore wind target, even under optimistic procurement assumptions. Delays, cancellations, and lengthy build times are major constraints.

• Onshore wind also lagging
  Despite growing corporate PPA support, GB is on track for just 22 GW of onshore wind by 2030, ~5 GW below the CPAP target. Regional buildout is hindered by policy barriers and grid constraints.

• System-level impacts
  Our projections show that excess renewable generation could affect nearly half of all hourly delivery periods in December 2029 with impacts also seen during summer months.

Key insights include:

• Realistic capacity projections for solar, onshore, and offshore wind

• The interplay between clean power buildout and rising electricity demand

• The implications of excess generation on curtailment, exports, and pricing

• How grid, storage, and policy developments could reshape the pathway to 2030
