Welcome to Market Brief, the Electricity Authority’s weekly update on regulatory and market developments.




Consultation on proposed list of distributed generation eligible to qualify to receive ACOT, lower South Island


We are seeking views on the proposed list of distributed generation in the lower South Island that would be eligible under the regulated terms in Part 6 of the Code to receive avoided cost of transmission (ACOT) payments from distributors.

We amended the Code in December 2016 to alter the arrangements relating to ACOT payments. The Code requires the Authority to publish a list of distributed generation for each of the four transmission planning regions eligible to qualify to receive ACOT payments.

The proposed list for the lower South Island relies on analysis provided by Transpower about what distributed generation in the lower South Island it needs to meet the grid reliability standards. Transpower’s analysis is included in a report accompanying the proposed list.

The new ACOT arrangements create substantial long-term net benefits to consumers, particularly by removing inefficient incentives on the investment in, and operation of, distributed generation.

Submissions are due 30 January 2018. The Authority will finalise and publish the list after considering submissions.

We expect to consult on proposed lists for the lower North Island, Upper North Island and Upper South Island during 2018.
