Annual Charge Setting - data submission flexibility

In advance of a change in regulatory price control period (e.g. from RIIO T1 to RIIO T2) the full range of input variables to set annual revenues/charges may not be finalised until after some of the early STCP submission deadlines. This proposal recommends increased flexibility for the Onshore TOs and NGESO to agree minor temporary changes to any revenue data exchange impacted in this way, such that they can fulfil their STC obligations.
