Formal title: Introduction of a seasonal Zonal Transmission Losses scheme
This Modification is based on the seasonal alternative solution to P198 developed at the Modification group but without any phasing. Seasonal zonal Transmission Loss Factors (TLF) (the “applicable TLFs”) would be derived ex ante for application to generation and demand BMUs within a zone (the “applicable zone”) for each of the four BSC seasons. The proposed scheme would retain the current process for allocating transmission losses to generation and demand (45% of transmission losses to production accounts and 55% to consumption accounts).
On 17 July 2008, the Authority published an open letter (see below) stating it was no longer in a position to reach a decision on the following Modification Proposals: P198 – Introduction of a Zonal Transmission Losses scheme P200 – Introduction of a Zonal Transmission Losses scheme with Transitional Scheme P203 – Introduction of a seasonal Zonal Transmission Losses scheme P204 – Scaled Zonal Transmission Losses. These Modification Proposals are therefore closed.
