✨ Transmission Network Policies



4 JUNE 2008 NEW ZEALAND GAZETTE, No. 92 2485

Connection to and use of the national grid

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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

  1. 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.

  1. Transpower should develop and submit grid upgrade plans to the Commission for
    approval.

  2. Any grid upgrade plan submitted by Transpower should be as comprehensive as
    possible, ideally covering and identifying the relationships between short, medium
    and longer term proposals, except where urgency is required for individual projects.
    The rigour of analysis supporting projects should be reasonable given the size of
    the project. This will better enable consideration of the interrelationships between
