Decarbonising The Power Sector

The Public Accounts Committee (PAC) announced that it has published a report on Decarbonising the power sector, highlighting that the government’s ambitions for power sector decarbonisation by 2035 are jeopardised by the lack of an overarching delivery plan.

It states that while the Department currently has many separate decarbonisation projects and programmes, it recommends that these should be consolidated to form an integrated, coherent delivery plan as soon as possible. Further conclusions and recommendations are summarised below.

>  The Committee expressed scepticism with the current plans for expanding nuclear, solar, and wind and their potential credibility and recommends that the Department should provide annual updates to Parliament to demonstrate milestones of progress and identify how risks are being mitigated.
>  The Committee is not convinced that the government is providing enough clarity to the private sector to attract the investment that is necessary to build new generating capacity. It recommends that the Department should set out in its delivery plan how it will provide greater clarity to the private sector to encourage necessary investment.
> The Committee does not think it is clear the Department has the support it needs from other departments to achieve the power sector decarbonisation ambition and recommends that the Department sets out in its Treasury Minute response how it will collaborate with other departments and prioritise decarbonisation.
>  The Department has not yet set out how it expects decarbonising the power sector will impact energy bill payers and taxpayers and the PAC recommends publishing information on this in its delivery plan, to be updated regularly.

The Committee said it is not yet clear what the epartment’s plans are in respect of energy efficiency and consumer behaviour.

The decarbonising the power sector report recommends that alongside its Treasury Minute response, the Department should write to the Committee setting out its modelling demand assumptions and how this is reflective of policies and plans to promote energy efficiency in customers and influence consumer behaviour.

Power Sector Decarbonisation: What It Means for UK Business Energy Costs

The Public Accounts Committee finding that the 2035 clean power target is jeopardised by a lack of delivery planning has direct implications for UK businesses with long-term energy strategies. If grid decarbonisation slips behind schedule, gas-fired generation will continue to set marginal electricity prices for longer, keeping the link between gas market volatility and business electricity bills firmly in place.

For procurement teams, this uncertainty reinforces the case for flexible contracts and regular market reviews rather than locking in long fixed-price deals without sufficient market intelligence. It also strengthens the business case for on-site renewable generation, solar panels, battery storage and combined heat and power, which reduce a business exposure to wholesale price swings regardless of grid decarbonisation progress.
