Coordination across Electricity T/D (Transmission/Distribution) is a key aspect of Distribution System Operation (DSO). For the past five years, Open Networks has enhanced T/D coordination and implemented change across a range of areas.
This includes:
- Investment planning - Network Options Assessment (NOA), through which major National Electricity Transmission System (NETS) reinforcements projects to meet the future network requirements are identified and recommend
- Improvements to Future Energy Scenarios (FES) which represent a range of different, credible ways to decarbonise our energy system as we strive towards the 2050 target
- Operational planning through enhanced and more coordinated approaches for data exchange between T/D.
Products in this work area are taking learnings from the Regional Development Programmes (RDPs) and Pathfinder projects to inform the development of common approaches that can be adopted by all network companies.
In addition, we will also undertake work to support a standard approach for DNOs to deliver the new Network Development Plan (NDP) licence obligation.
Things we're doing this year
We are continuing to improve interactions and co-ordination between electricity transmission and distribution, taking a whole electricity system approach. The project team has identified five areas for development, all of which will continue from 2021:
- Delivering further alignment between Future Energy Scenarios and Distribution Future Energy Scenarios
- Reporting on the cost benefit analysis for gaining visibility of Distributed Energy Resources
- Providing a recommendation and implementation plan for operational and forecasting data sharing between the ESO and DNOs. Sharing real-time operational data with external non network market participants
- Reviewing and updating the Network Development Plan Form of Statement
- Reviewing and updating the Whole Electricity System Co-ordination Register-Form of Statement
