Ofgem has published a letter to stakeholders to provide an update on timing and next steps on Future Charging and Access reforms. The regulator has three ongoing projects that serve as a review of transmission, distribution and balancing charging to help facilitate a transition to a more effective network. These are:
- Electricity Network Access and Forward-looking Charging reform (Access reform)
- A Significant Code Review (SCR) designed to develop improved access and forward-looking charging arrangements
- A wide-ranging review of Distribution Use of System (DUoS) charges
- A focused review of Transmission Network Use of System (TNUoS) charges
- Targeted Charging Review (TCR)
- A review of residual network charges, as well as some of the remaining Embedded Benefits to explore how costs may be more fairly shared amongst users
- Balancing Services Charges Task Force
- Designed to operate in parallel to the SCR and TCR, Ofgem have established an industry-led task force to evaluate Balancing Services Use of System (BSUoS) charges
- The Task Force are evaluating how cost reflective and effective current BSUoS charges are
The new timeline
Ofgem have updated the timelines for the TCR and Access reform, providing clarity on dates in their original consultations.
The TCR consultation nominated April 2020 and April 2021 as potential dates for the reform of Embedded Benefits to come into effect. Ofgem have now ruled out April 2020, citing April 2021 as their preferred date. Options for the implementation date for new residual charging arrangements were April 2021 or phasing between 2021 and 2023. The regulator has indicated that they now consider April 2023 as a leading option, alongside the other two.
Regarding the Access reform, Ofgem originally scheduled changes to transmission charges to come into effect in April 2022, and changes to distribution arrangements in April 2023. This has now been revised to April 2023 for both changes.
Future Triad periods
Under the TCR proposals transmission demand residual charges (Triads) would be changed to a fixed or agreed capacity, avoiding the incentive for Triad avoidance in the future. The nomination of a potential implementation date of April 2023 for new residual charging arrangements increases the likelihood that the last Triad could be Winter 2022/23, totaling three Triad periods overall.
