3 Conclusion First Report - Grid Capacity in Wales Acknowledged

To ensure that communities and business in Wales can decarbonise in line with government targets,...

To ensure that communities and business in Wales can decarbonise in line with government targets, grid infrastructure must be able to meet the projected increase in demand for electricity. The evidence we received suggested that the grid in Wales will not be suitable to facilitate the decarbonisation of heat and …

Government response. The government acknowledges the importance of grid infrastructure to meet the projected increase in electricity demand. They reference the British Energy Security Strategy (BESS) and the appointment of an Electricity Networks Commissioner but do not commit to specific actions to …

4 Conclusion First Report - Grid Capacity in Wales Accepted

While we understand that the UK Government must consider the energy and network needs of...

While we understand that the UK Government must consider the energy and network needs of the UK as a whole, we consider that it would be inequitable if the UK were to benefit from Wales’ natural resources for renewable energy generation while Welsh households, businesses and industry were not adequately …

Government response. The Government states that strategic planning will always take account of network needs in Wales, pointing to the Holistic Network Design (HND) as the first step towards a Centralised Strategic Network Plan (CSNP), and mentioning Welsh Government representatives input.

We recommend that the UK Government task the new Electricity Networks Commissioner to determine the grid infrastructure necessary to enable industry, communities and businesses in Wales to decarbonise heat and transport in line with net zero targets.

Government response. The government is reducing timelines for delivering strategic onshore transmission network infrastructure and appointed an Electricity Networks Commissioner, who is leading a project to identify areas where improvements could be made.
Wales Office
6 Conclusion First Report - Grid Capacity in Wales Acknowledged

We recognise the strengths of an electricity grid that serves the whole of Great Britain.

We recognise the strengths of an electricity grid that serves the whole of Great Britain. However, we conclude that there are distinct challenges and opportunities relating to grid infrastructure in Wales that require specific focus and intervention from the UK Government.

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. 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.
Wales Office
10 Conclusion First Report - Grid Capacity in Wales Accepted

We are encouraged that Ofgem is reviewing connection arrangements and we look forward to hearing...

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 …

Government response. 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 …
Wales Office
13 Conclusion First Report - Grid Capacity in Wales Accepted

We are encouraged to see that the UK Government recognises that grid connection costs can...

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”.

Government response. 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.
Wales Office
14 Recommendation First Report - Grid Capacity in Wales Accepted

It is not equitable that grid reinforcement costs should be shared by consumers in an...

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 …

Government response. 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.

There is a multiplicity of different bodies involved in securing planning consent for grid infrastructure and this process needs to be streamlined. We welcome the commitment to cutting processing times by fifty per cent and appreciate the challenge that this constitutes. However, in light of the evidence we received, it …

Government response. The Government recognizes the need to streamline the planning consent process and is amending the energy National Policy Statements (NPSs) and working with Ofgem to expedite the regulatory approvals process.

Ofgem, as the market regulator, must ensure that the regulatory environment enables the decarbonisation of energy markets. Whilst ensuring the best value for consumers is important and should remain one of Ofgem’s primary considerations, this should be balanced against achieving net zero targets.

Government response. The government does not consider an amendment to Ofgem’s primary duty necessary, as they believe the existing duty to protect consumers' interests already includes the reduction of greenhouse gases.
Wales Office
20 Recommendation First Report - Grid Capacity in Wales Rejected

We recommend that the UK Government amend Ofgem’s primary duty to include both ensuring the...

We recommend that the UK Government amend Ofgem’s primary duty to include both ensuring the best value for consumers and achieving net zero targets, by bringing forward government amendments to the Energy Bill. This would provide strong signals to developers and grid infrastructure owners.

Government response. The government does not consider an amendment to Ofgem’s primary duty necessary, as they believe the existing duty to protect consumers' interests already includes the reduction of greenhouse gases.

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 …

Government response. Ofgem is revising how customers are charged for connecting to distribution networks to reduce connection costs, and project approval is a matter for Ofgem.
Wales Office
22 Recommendation First Report - Grid Capacity in Wales Accepted

The Government should outline the circumstances in which higher grid construction costs, for example due...

The Government should outline the circumstances in which higher grid construction costs, for example due to undergrounding, are justified to enable rural communities to keep pace with the decarbonisation transition.

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