New South Wales Consolidated Regulations

ELECTRICITY SUPPLY (SAFETY AND NETWORK MANAGEMENT) REGULATION 2008 - SCHEDULE 1

SCHEDULE 1 – Chapter 1 of network management plan-network safety and reliability

(Clause 9 (3))

1 Description of transmission or distribution system

A description of a transmission or distribution system and its planning, design, construction, operation and maintenance must include references to the following:

(a) maps showing the location of the system’s electricity works and the procedures for gaining access to those maps,

(b) design and construction standards and procedures for the system’s electricity works,

(c) system reliability planning standards,

(d) technical customer service standards for quality and reliability of supply,

(e) maintenance standards and procedures for the system’s electricity works,

(f) operation and work procedures for the system (including procedures for work on or near both de-energised and live electricity works),

(g) safety equipment design, use and maintenance standards and procedures for the system,

(h) a description of the engineering records, drawings and maps that the network operator maintains relating to the system.

2 Description of planning process

A description of the planning process employed for the purpose of assessing the adequacy of the transmission or distribution system and the need for development of the transmission or distribution system must include the following:

(a) the process used for setting system reliability planning standards and identifying development needs and demand management opportunities,

(b) strategies for managing and complying with that process and those standards.

3 Description of asset management strategies

A description of the asset management strategies employed for the purposes of the design, construction, operation and maintenance of the transmission or distribution system must include the following:

(a) the process used for setting design, construction, operation and maintenance standards and customer technical service standards for quality and reliability of supply,

(b) strategies for managing and complying with that process and those standards.

4 Analysis of hazardous events

(1) An analysis of hazardous events must, consistent with the size and complexity of the transmission or distribution system:

(a) systematically identify hazardous events that might be expected to occur, and

(b) identify the potential causes of those events, and

(c) state the possible consequences of those events, and

(d) specify operational, maintenance and organisational safeguards intended to prevent those events from occurring or, should they occur, intended to protect operating personnel, plant, equipment, the community and the environment.

(2) The operational and maintenance safeguards must include a maintenance schedule indicating, among other things, the type and frequency of inspections and tests of the transmission or distribution system (including checks on protection devices).

(3) In the case of new transmission or distribution systems, an analysis of hazardous events should also take into account hazardous events occurring during construction.

5 Emergencies

(1) The types of emergencies in respect of which procedures are to be implemented include:

(a) fires, explosions and impacts (with particular reference to those caused by the activities of other parties), and

(b) natural disasters, and

(c) civil disturbances.

(2) A plan must demonstrate that the network operator regularly tests and, as far as practicable, has proved the emergency procedures.
