Project duration: July 2017 to September 2019
Regen’s whole-system thinking is seeking to understand how both the electricity and gas networks will evolve, in a decentralised and decarbonised UK energy system. Building on the growth scenarios work Regen has undertaken for WPD and other DNOs, Wales and West Utilities (WWU) commissioned Regen to develop a methodology to create regional growth scenarios to support long term demand and investment planning for the gas network.
The development of this methodology used common assumptions and approaches that Regen developed for electricity network scenarios, but also developed an approach that was bespoke for sources of demand and supply connected to gas distribution networks. The scenarios focus on the evolution of heat demand, delivery technologies and fuels, the growth of gas fired power generation and the changing gas supply mix, including the introduction of hydrogen and injection of biomethane.
WWU used the outputs of this assessment of their network, to inform their business plan submission to Ofgem in 2019.
