To help customers understand and prepare for pricing changes under the new Transmission Pricing Methodology (TPM), we published several indicative pricing updates after submitting our initial proposal to the Authority.
The indicative prices provided on this page are an example of what transmission charges could be if the TPM was applied to that year. We have projected out to the 2034/35 pricing year to indicate how indicative prices may evolve over time.
Our indicative prices were produced from the model we developed and updated during the TPM development phase (which comprises a number of process steps, databases and Excel spreadsheets). They are not a formal calculation or notification of transmission charges.
We recommend that anyone making decisions based on the indicative prices should consult the new TPM, any relevant information they have access to, and seek independent expert advice.
We have now notified customers of their 2023/24 prices and updated our Grid Pricing web page with the relevant information.
