Regen's response to Ofgems consultation on modelling future supply and demand

We see value in moving away from multiple scenarios to a central pathway (potentially with sensitivies) in the near term.

Having multiple longer-term scenarios that meet net zero, and a counterfactual scenario that does not, remains a useful framework for network planning, that acknowledges that not all policy energy sector pathways have been clearly defined.

We do not see value in pathways and scenario projections being modelled around current network constraints. By definition, scenario analysis should be useful to inform where and when network investment needs to be prioritised, and should not be tethered to existing infrastructure planning and policies.

Further increasing the transparency of the FES data is something Regen strong supports. Further visibility of modelling methods, assumptions, input data and approaches to feeding in stakeholder  input would be valuable to multiple energy and spatial planning bodies.

An annual FES publication should be retained, alongside the proposed central strategic network plan.
