Application

This standard applies to:

(a) All electricity transmission and electricity distribution assets in one or more systems with a total capacity equal to or greater than 10 MVA;

(b) All electricity generation assets in one or more systems with a total capacity equal to or greater than 10 MW;

(c) All gas distribution assets in one or more systems, including all natural gas and LPG vapour distribution assets, that operate at a pressure equal to or less than 2000 kPa, and:

(i) Supply more than 10 terajoules of gas in any year, or

(ii) Have a flow design capacity equal to or greater than 10 gigajoules per hour.

The total capacity for each asset type applies to each energy asset owner or operator irrespective of whether those assets are in one system or separate systems.

Inclusions In addition to 1.21 the following are within the scope of this standard:

(a) Control centres;

(b) Gas measurement systems, where they are part of a gas distribution system as in 1.2.1(c);

(c) Gas measurement systems where they are connected to but are not part of gas distribution assets as in 1.2.1(c);

(d) Gas odorisation facilities;

(e) Survey vehicles for gas systems;

(f) Transportable network equipment in-service such as transportable transformers, or CNG tanks;

(g) Watercourses that are used in the production of electricity where additional risks arise from the presence of generation assets or their operation;

(h) Rapid rise in water level, high velocity flow and presence of turbulent or aerated water beyond any watercourse point of control (control gate, turbine) that may occur due to the process, for example, required compensation releases, rapid start-up or load ramping of hydro machines;

(i) Damage to river banks and lake shorelines not covered by consent conditions or the Resource Management Act; and

(ii) Flooding of dry river beds or other watercourses.
