Northern Powergrid has urged Ofgem to return to a shorter asset life for new investments by electricity distribution networks to ensure intergenerational equality and prevent a future rise in energy bills. Speaking to Utility Week following the publication of its draft business plan for the RIIO ED2 price controls, the company’s policy and markets director Patrick Erwin also accused the regulator of becoming “politicised” and “behaving in a way that could be trying to get the right headline rather than the right outcome.” He insisted "the jury's out" on the leadership of Ofgem.
