About this map
This mapping portal forms part of our Distribution Annual Planning Report (DAPR) and presents:
- the topology of our regulated network, including transmission network connection points, substations, sub-transmission network and distribution feeders.
- forecast loads for transmission network
- connection points, forecast loads and capacity information for each of our substations and sub-transmission feeders
- distribution feeders that are forecast to have capacity constraints in the next 2 years
- 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
The subtransmission line tables include the following information:
-
Planning Region
- Ergon Energy Ecorp Asset ID
- Ergon Energy operational number
- Subtransmission line description
-
Summer capacity & load forecasts for 5 years
- Rating (Amps)
- Loading (Amps)
- Power Factor
Definitions
SD: Summer Day (9am to 5pm)
SE: Summer Evening (5pm to 10pm)
SNM: Summer Night/Morning (10pm to 9am)
Summer: December to March

Poor power factors of some feeders
Where the power factors are very low it is because (in general) the feeder is part of a ring network with circulating reactive power. The active power is swamped by the reactive power in these cases. There are some radial feeders where the power factor is also very low. This is as a result of very little active power being supplied by these feeders combined with a lot of line charging reactive power which once again swamps the active power component. -
Missing power factors
This is a result of unloaded feeders that are only energised from one side. There is some line charging which accounts for the non-zero loading in amperes but there is no active power supplied by the feeder.

The Transmission Connection Point Forecasts include the following information for 50 PoE and 10 PoE in summer and winter:
- Ergon Energy region
- TNI: National Electricity Market - Transmission Node Identity
- TCP Name: Name of the Transmission Connection Point
- Forecast Peak Load (MW)
- Forecast Peak Load (MVARu) (VARu = Volt Amps Reactive Uncompensated, i.e. with stated compensation not active)
- Forecast Compensation (MVAR)
Exclusions
Forecast capacity is not
given this spreadsheet. In the majority of cases, the
capacity at the TCP is controlled by the Transmission
Network Service Provider, and hence reported by them. In the
relatively few cases where Ergon Energy asset boundary at
the TCP is inclusive of power transformers, the substation
capacity will appear in the Zone or Bulk Supply Substations
Forecasts tables. The forecast loads are given exclusive of
any connected embedded generation.
The Distribution Feeder Limitations tables include the following information for each constrained distribution feeder:
- Ergon Energy region
- Distribution feeder name, ID & location
- Load exceedance after 2 yrs (MVA)
- Forecast season that exceedance occurs (Summer / Winter)
- Forecast year that exceedance occurs
- Forecast month/s that exceedance occurs
- Load reduction needed to delay the exceedance by 12 months (MW) (assumed power factor of 0.9)
Solutions
Suggested solutions, in
order or preference, are included under the 'Solutions' tab.
Connection points for possible load reduction
In all cases, the connection point to apply load
reduction would be downsteam of the substation exit feeder
cable and/or first section of line.
Exclusions
Dedicated customer
connection assets are excluded from the analysis.
