Regen has undertaken a number of regional Distribution Future Energy Scenario (DFES) studies on behalf of electricity and gas distribution networks. We are currently conducting DFES studies for Western Power Distribution (WPD) and Scottish and Southern Electricity Networks (SSEN), and you may have seen our recent stakeholder engagement events for these projects.

The DFES studies are intended to provide the networks with a set of local and regional future scenario projections for the growth of low carbon technologies, housing and commercial developments, energy storage and conventional generation, which the networks can then use to model and stress test the impacts on their networks and identify the need for network reinforcement. This year the DFES is especially important as the electricity distribution networks prepare their RIIO ED2 business plan and investment submissions for the next price control period, which runs from 2023 to 2028.

We get asked a lot of questions regarding what the DFES is, how the scenarios are produced, how they link to the National Grid Future Energy Scenarios, what data is provided  and how stakeholder input is gathered. So to answer some of those questions, and several more, we have produced a Distribution Future Energy Scenarios Frequently Asked Questions guide.

If you are DFES curious, you can download the guide here or view it below.

If you have additional questions we would be very happy to hear from you, please contact Johnny Gowdy, director and lead on the development of our advisory projects, at
