Key messages for you:
- TRANSITION has delivered an evidential base to inform decisions on market design for flexibility services and proven the value of collaboration and coordination, leading to a whole systems approach in ED2.
- Simplified contractual arrangements are key to enabling wider participation and unlocking flexibility from aggregators and suppliers.
- A liquid market requires a fair price for flexibility that reflects the associated local and wider socio-economic benefits and the value obtained freely by other market actors, such as the ESO.
- TRANSITION successfully tested the neutral facilitation of a marketplace can enable the delivery of a variety of flexibility and capacity services and products (delivery timescales).
- A diverse range of data sources from supply through delivery to use can improve short-term planning and decision making.
- Robust digital models of the LV network at the street level form the basis for accurate forecasts that can enable greater uptake of LCTs.
- The automation of PSA modelling at all voltage levels can facilitate the identification and communication of flexibility requirements within DNOs and to potential flexibility providers.
- Automatic constraint prediction and economic optimisation tools are required to enable the efficient use of flexibility at scale.
What does DSO mean for you:
- A clear framework for how to work together and align plans to support the whole system picture

The key learnings from TRANSITION and what we are doing next…
Key Learnings and Outcomes
- Framework Agreements can enable closer to real time procurement and thereby scale up the procurement of flexibility
- TRANSITION developed a robust End-to-End (E2E) process which can be used as a good basis for industry wide flexibility processes.
- The S&D and PSA tools developed by TRANSITION can reduce the time taken to contract and deliver flexibility, enabling procurement closer to real-time.
- Forecasting accuracy is improved by access to real time data, such as that provided by NeRDA and ElectraLink.
- The ENA baselining tool can provide a solid basis for future development, but users should consider limitations within these methodologies and their suitability for different DER types.
What are we doing next?
- Via the ON-P, promote the TRANSITION Flexibility Service Agreement as a framework agreement with increased standardisation of Appendices.
- Via the ON-P, promote the E2E process to further standardise flexibility procurement across DSOs.
- Share detailed information and insight across different organisations to support the development of DSO tools.
- Use learnings to inform the requirements / specifications for a new DSO forecasting tool and share widely through ON-P.
- Share our feedback on the baselining methods to support future methodologies.
