✨ Transmission Policy Objectives
27 MAY 2009 NEW ZEALAND GAZETTE, No. 75 1737
• stakeholders and the public are kept well informed about how agreed minimum levels of grid reliability are to be maintained throughout the development and consideration of any grid upgrade plans.
Connection to and use of the national grid
-
The national grid is essential to all connected parties, and should be maintained and operated to a common set of grid reliability standards. These common standards should be embodied in rules that recognise the interconnected nature of the network.
-
Grid reliability standards should apply to agreements between Transpower and its customers dealing with connection to and use of the grid, investment planning (including replacement), transmission system design and construction, and transmission system maintenance.
-
The common standards for the grid should be determined by the Commission, following consultation with Transpower and affected parties. The Commission should, from time to time, review the standards to ensure that they promote a secure and reliable grid and that the interests of end-customers are properly taken into account.
-
Transpower’s customers should be permitted some flexibility over standards (which could be higher or lower than the norm), so long as the integrity of the core grid is not compromised. The Commission should ensure that arrangements are in place to protect the interests of third parties when Transpower and one of its customers agree to a local variation from common standards.
-
All transmission customers should be required to have a transmission agreement with Transpower, and the Commission-developed benchmark agreement is the default agreement if the parties are unable to agree.
Investment in and maintenance of the transmission network
- As part of its modeling and forecasting work, the Commission should provide for the development of statements of opportunities relating to transmission. These should:
• incorporate electricity demand and supply forecasts
• enable identification of potential opportunities for:
o efficient management of Transpower’s transmission network including investment in system expansions, replacements and upgrades
o transmission alternatives (notably, investment in local generation, demand-side management and distribution network augmentation)
• facilitate long-term planning for timely securing of easements and resource consents, including to facilitate the connection of renewables.
• be prepared at least every two years.
- Transpower should develop and submit grid upgrade plans to the Commission for approval.
