ELECTRICITY DISTRIBUTION REGULATIONS 1997 - REG 29

29 .         Network planning criteria

        (1)         A corporation must prepare criteria relating to the planning of its electricity distribution network on or before 1 May 2006.

        (2)         A corporation may from time to time amend the network planning criteria.

        (3)         Before amending the network planning criteria in a manner which it reasonably believes to be material, a corporation must make publicly available details of the proposed amendment and allow a reasonable period of time for persons affected by the proposed amendment to comment on the proposed amendment.

        (4)         The network planning criteria must be consistent with the Distribution Technical Code and must contain the following in relation to both the interconnected network and the regional power systems:

            (a)         contingency criteria;

            (b)         steady‑state criteria, including —

                  (i)         real and reactive generating criteria;

                  (ii)         voltage limits;

                  (iii)         frequency criteria;

                  (iv)         thermal rating criteria; and

                  (v)         fault rating criteria;

            (c)         stability criteria, including —

                  (i)         transient stability criteria;

                  (ii)         dynamic stability criteria;

                  (iii)         voltage stability criteria; and

                  (iv)         frequency stability criteria;

            (d)         quality of supply criteria, including —

                  (i)         voltage fluctuation criteria;

                  (ii)         harmonic voltage criteria;

                  (iii)         harmonic current criteria;

                  (iv)         voltage unbalance criteria; and

                  (v)         electro‑magnetic interference criteria;

            (e)         distribution carrier selection criteria;

            (f)         construction standards criteria; and

            (g)         environmental criteria.

        (5)         A corporation must provide a copy of the network planning criteria (as amended) to any user or applicant who requests a copy of it.

        (6)         Without limiting a corporation’s obligations under the Act, any proposal to augment its electricity distribution network must be consistent with the network planning criteria to the extent that the corporation reasonably believes the network planning criteria are applicable in the circumstances.
