PM084: Improvements to Revenue Forecast Information Provision under STCP24-1

Suppliers and Generators have asked for the transparency of TNUoS Tariff forecasts to be improved by publishing a breakdown of the allowed revenue assumptions in those forecasts into the main components under RIIO price controls. Without this information Suppliers and Generators do not know the underlying revenue assumptions in tariff forecasts and therefore cannot assess the risk of revenue changing or model their own revenue assumptions. The information currently provided to National Grid by other Transmission Owners under STCP24-1 does not explicitly require this level of information. This can lead to inconsistent approaches or information missing from Transmission Owner submissions.
