This trial would mitigate the effect of the £200/kW rule (High Cost Cap) so that when a group of customers sought a connection within a set time period and the aggregate capacity sought by those customers exceeds the £200/kW threshold (as if they were treated as a single connection scheme with this capacity), the reinforcement costs would be shared between those customers in proportion to the capacity in their connection offer (rather than being charged to the first customer that triggers the High Cost Cap).
As derogation from our Connection Charging Methodology would be required under the trial arrangements the approach was discussed directly with Ofgem and also with stakeholders at the CCSG. Advice on the approach was taken from CCSG members and Ofgem requested further information on the detail of the trial in order to consider the derogation further.
