About this map

This mapping portal forms part of our Distribution Annual Planning Report (DAPR) (5.2 MB) and presents:

  • the topology of our regulated network, including transmission network connection points, substations and sub-transmission network
  • forecast loads for transmission network
  • connection points, forecast loads and capacity information for each of our substations and sub-transmission feeders
  • joint owned connection points
  • sub-transmission & substation constraints that are forecast to emerge in the next 5 years.

As a Distribution Network Service Provider (DNSP), we are required to publish this information under Rule 5.13 and Schedule 5.8 of the National Electricity Rules (NER).

Forecast Information

Definition of Terms - Bulk Supply Point Capacity and Forecast Tables

Peak Risk Period

The time period over which the load is highest (Day/Night).

NCC Rating (MVA)

Normal Cyclic Capacity - the total capacity with all network components and equipment in service.

Contracted non-network (MVA)

The amount of embedded generation and contracted curtailed demand management capacity available within the supply area of a substation during peak times. The impacts of these have been incorporated into the load forecasts. Solar PV connections are not included in the reported figure.

10 PoE Load (MVA)

Peak load forecast with 10% probability of being exceeded (one in every 10 years will be exceeded). Based on normal expected growth rates and weather corrected starting loads.

LARn (MVA)

Security standard load at risk under system normal condition, expressed in MVA.

LARn (MW)

Security standard load at risk under system normal condition, expressed in MW.

Power Factor at Peak Load

Compensated power factor at 50 PoE Load.

ECC Rating (MVA)

Emergency Cyclic Capacity – the long term firm delivery capacity under a single contingent condition. The maximum permissible peak emergency loading for a given load cycle that an item of plant can supply for an extended period of time without unacceptable damage.

Remote Trans Avail (MVA)

Load transfers that can be implemented through SCADA switching procedures by the network control officer. It is assumed that this can generally be achieved within 30 minutes.

Manual Trans Avail (MVA)

Load transfers can also be deployed via manually controlled switchgear locally by field staff.

Mobile Plant Avail (MVA)

The capacity of mobile substation or mobile generation that can be deployed within the timeframe and capacity prescribed by the security standard.

POPS

Plant Overload Protection Scheme (POPS) consists of several applications which continuously monitor specific items of plant for overload conditions. If overload conditions are detected and validated, POPS will initiate predefined actions in order to relieve the overload condition.

LARc (MVA)

Security standard load at risk for single contingent conditions.

LARc (MW)

Estimated generation / load reduction required to defer the forecast system limitation. This is the security standard load at risk under single contingency condition, expressed in MW.

Customer Category

For security standard application, the general type of customer a substation or feeder supplying the area.

For further information, please refer to Appendix D of Energex Distribution Annual Planning Report.

The tables show information for Jointly Owned Substations in the Energex network. These are typically substations that Powerlink own, and are Transmission Connection Points to the Energex network. It should be noted that for Jointly Owned substations, Energex typically only owns the switchgear at the connection point, and as such the Energex ratings will not reflect the rating of upstream equipment not owned by Energex. For further information, please refer to Appendix D of Energex Distribution Annual Planning Report.
