Planning assumptions

Putting stakeholders at the centre of our business


At this time of change for the energy system it is difficult to establish a single forecast on which to base our business plans. We propose to use the Future Energy Scenarios (FES) that we produce as the System Operator on an annual basis.

We are currently considering the 2017 scenarios, but will consider the 2018 scenarios when they are finalised in July 2018. We propose to look at what is common across the scenarios in establishing our baseline plans and to consider where uncertainty exists and the drivers of change and cost in these plans. We will be working with stakeholders over the coming months to consider and agree these assumptions, uncertainties and drivers.
