9 Conclusion First Report - Grid Capacity in Wales Accepted

Upfront connection costs can be prohibitive and prevent the development of energy projects.

Upfront connection costs can be prohibitive and prevent the development of energy projects. This results in a “chicken and egg” situation whereby developers wait for other developers to commit to the funding of connection costs.

Government response AI summary
The government points to Ofgem's decision to socialise a proportion of network reinforcement costs, BEIS's amendment to connections legislation, existing frameworks for developers to share connection costs and Ofgem incentive schemes as addressing the committee's concerns.

We are encouraged that Ofgem is reviewing connection arrangements and we look forward to hearing more about the progress being made in the run up to 1 April 2023. We consider that due to the tight timeframes set by government net zero targets, urgent work should be done to overcome … Read more

Government response AI summary
The government describes existing mechanisms to address upfront costs and incentivise developers to share grid connection and reinforcement costs, including Ofgem's decision to socialise a further proportion of network reinforcement costs and existing legislation allowing developers to share costs and receive reimbursement from second comers.

We are encouraged to see that the UK Government recognises that grid connection costs can be prohibitively high for developers. However, we are concerned by the decision to move more of the reinforcement costs to the network charges paid by “all electricity consumers in the area”. Read more

Government response AI summary
The government points to Ofgem's decision to socialise a proportion of network reinforcement costs and BEIS's amendment to connections legislation to enable these reforms as addressing the committee's concerns.

14 Recommendation First Report - Grid Capacity in Wales Accepted

It is not equitable that grid reinforcement costs should be shared by consumers in an area because this would create a higher burden for rural households and businesses and those in areas which historically lack existing grid infrastructure. We ask Ofgem and the UK Government to define what is meant … Read more

Government response AI summary
The costs of connecting a project to the existing network are charged to the connecting customer, and from April 2023, reinforcement costs will be met by electricity billpayers in the relevant distribution area.

The UK Government should work with National Grid ESO, NGET, the DNOs and Ofgem to revise consenting processes to align the allocation of grid capacity with the application for planning permission. National Grid’s work should be expedited on reviewing commercial contracts with developers reserving grid capacity, where those projects have … Read more

21 Conclusion First Report - Grid Capacity in Wales Accepted

The policy in favour of laying cables underground in AONBs is welcome.

The policy in favour of laying cables underground in AONBs is welcome. However, due to the significantly higher construction costs it is likely that overhead lines will simply be re-routed around AONBs. This will mean that communities and businesses in those areas will remain isolated from grid infrastructure and face … Read more

Government response AI summary
Ofgem is revising how customers are charged for connecting to distribution networks to reduce connection costs, and project approval is a matter for Ofgem.
