CPW139d will merge three (3) processes for reviewing unmetered or assessed charges and tariff changes into one single process and integrate this into the Bilateral Hub. The three processes that will be merged into a new H3 process are: H3 – Review of charges at unmeasured1 or assessed supply points H4 – Wholesaler notice of change in tariff applied to a service component. H5 – Retailer application for change in tariff applied to a service component. Merging these processes and integrating them into the Bilateral Hub will allow more accurate monitoring of these activities, which is currently unavailable. Merging these processes into the Bilateral Hub will improve the consistency of advice to customers on the expected resolution times for these processes and will improve efficiency.
