●  Legislative framework, e.g. Electricity Industry Act, Electricity Safety Act, national electricity laws and rules

●  System modelling

●  Market mechanisms

●  Load management strategies including segmented customers to minimise community impacts

●  Public communication and engagement

Mitigation table

   

AEMO is a participating agency, as shown in the Mitigation table (Table 8), for the following gas supply disruption mitigation activities:
●  Legislative and regulatory framework, including Gas Industry Act 2001, Gas Safety Act 1997 and associated Gas Safety Cases, National Gas Law and National Gas Regulations, critical infrastructure resilience requirements under the EM Act 2013

Response (including Relief)

 

Provide information to the control agency on the extent and likely duration of major disruptions to electricity and gas supply

4.4, 4.5, 4.6

   

Provide information and advice to the control agency regarding the impact of an emergency on electricity supply or gas and formulate management strategies in relation to incidents that threaten the technical integrity of the generation and transmission system (system security incidents)

3.2, 4.6, 11.1, 11.2

   

Co-ordinate and direct the gas and electricity industry to respond to a system security emergency

11.1, 11.3

   

Recovery

 

AEMO works with DELWP (as lead Government liaison) to deliver the recovery activities:
●  electricity services assets reinstatement and return to reliable supply by managing electricity system security emergencies. AEMO operate and are responsible for the transmission system while other network operators manage the distribution system and the restoration of infrastructure and electric supply

●  gas services assets reinstatement and return to reliable supply by managing gas system security emergencies within the Victorian Declared Transmission System. Other pipeline operators manage non Declared Transmission System segments of the system, and the restoration of infrastructure and gas supply

19.1, 19.4, 19.7
