TPM impact model results
18 June, 2020
Background
The following are the results from the TPM impact model. The final charges are a result of a netted vSPD approach for the benefit charges and the use of the anytime maximum demand (AMD) to allocate residual charges. The proposal also includes a price cap to protect customers from big price increases
Results are broken down in to indicative charges, capping results, and residential impacts.
Indicative charges
