TPM Development Project Design Principles

We developed the following design principles to help guide the development of our new TPM proposal, as we make necessary trade-offs between options which otherwise comply with the TPM Guidelines.

Our goal was to develop the best TPM proposal we could, consistent with the new TPM Guidelines, the Electricity Authority’s statutory objective and any determination by the Commerce Commission under Part 4 of the Commerce Act 1986.
