TEF
In 2017 three projects were submitted for the Network Innovation Competition that supported the transition from Distribution Network Operator (DNO) to Distribution System Operator (DSO).
These were:
- TRANSITION, submitted by Scottish and Southern Electricity Networks and Electricity North West;
- Electricity Flexibility and Forecasting Systems (EFFS), submitted by Western Power Distribution; and
- FUSION, submitted by SP Energy Networks.


In the Project Directions issued by Ofgem for TRANSITION, EFFS and FUSION (T.E.F.), several conditions were included including the need to reduce the risk of unnecessary duplication and ensure the projects deliver complementary learning. All the project participants welcome the opportunity to collaborate and ensure that collectively, the three projects deliver best learning outcomes and value for money.
Each of the partners recognise that this document represents the first step in what will be an ongoing process to identify further areas of shared learning and opportunities to deliver a better outcome for customers as the projects progress. This process will be enabled by the new governance structure which includes regular intra-project meetings, as well as the substantive Stage Gate at the end of the development phase. Evidence which will be provided at Stage Gate, will enable Ofgem to make an informed decision on proposals to commence of the implementation phase of the projects.
