Excerpt from the introduction:
In a 2019 Issues Paper under its Transmission Pricing Review, the Electricity Authority of New Zealand set out a framework for efficient electricity system investment, cost allocation, and pricing. The basic design accords with beneficiary-pays principles. The challenges of transmission investment preclude pure market approaches and require consistency across both competitive and monopoly elements of the system. In comments on the Authority’s proposal, submissions of some parties include critiques or alternative recommendations that appeal to implicit assumptions inconsistent with the basic requirements of the technology and associated electricity market components. Although perfection is only possible under narrow conditions, the Authority’s framework provides a careful balance that adheres to first principles and can accommodate workable implementation.
