The Outage Protocol specifies the circumstances in which Transpower may temporarily remove or reduce the capacity of any grid assets which are otherwise required to be provided under the Benchmark Agreement and Interconnection Rules. It also provides for procedures and policies for Transpower to plan for and carry out outages, and the management of unplanned outages on the grid.
The Outage Protocol had not been developed at the time of implementation of the Part F Rules. Instead, Section VII of Part F contained a process for preparing an Outage Protocol.
The Outage Protocol was subsequently developed by the Electricity Commission and recommended to the Minister of Energy and Resources. Following approval, it was included in the Electricity Governance Rules as Schedule F7 of section VII of part F.
An outage plan prepared under an Outage Protocol must include all reasonably foreseeable connection and interconnection asset outages in the outage plan year. The Outage Protocol specifies the process to be used by Transpower for developing an outage plan and what Transpower must take into consideration when doing so. It also includes the conditions under which unplanned outages may be carried out, and policies and procedures for dealing with unplanned outages.
Arrangements for making temporary grid reconfigurations
The Authority has decided to amend Part 12 of the Electricity Industry Participation Code 2010 (Code) to enable Transpower, with little or no notice, to temporarily remove one or more interconnection assets from service or temporarily reconfigure the grid, if doing so would improve security of supply (urgent temporary grid reconfigurations). These amendments continue to policy intent of the Code provisions made under urgency in February 2012 and March 2013. The Code amendments include various minor changes to Part 12 of the Code, to make the drafting consistent within and as between the clauses, since all clauses contain net benefit tests.
The Authority’s decision on the Code amendment proposal, and the Authority’s response to issues raised in consultation on the proposal, are described in a decisions and reasons paper that is available from the submissions page. The Authority’s summary of the submissions on the proposal is also available at on the submissions page.
The amendments to the Code will come into force on 16 December 2013, once the current urgent Code amendments expire. This reflects the fact that the draft Code amendments are designed to continue the policy intent of the urgent Code amendments.
