Ofgem is consulting on updating its Offshore Transmission Cost Assessment Guidance, with a final version expected later in 2026. This review aims to refine how costs for offshore transmission are evaluated.
What This Means
This consultation is a standard regulatory process, aiming to ensure fair and efficient cost recovery for offshore transmission infrastructure. While seemingly technical, these guidelines can indirectly affect consumer bills by influencing investment in renewable energy projects. We hope the updated guidance promotes cost-effective development, ultimately benefiting bill-payers through lower transmission charges and a more robust grid for offshore wind.
- Consumers: No immediate change to household bills, but worth watching.
- Businesses: Limited direct cost impact for businesses for now.
- Energy market: A structural or regulatory development to monitor.
