How the Grid Treats a Site: Broken Hill, NSW
Know how the grid treats a site before you commit: the constraints, outages, curtailment and loss-factor revenue behind it, on the line where they happen. Here is the whole screen for one real area, with every figure dated.

Six Steps, One Area
Broken Hill sits at the far western end of the NSW1 regional network, 220 kV from Buronga. It already hosts a solar farm and a wind farm, which makes it a useful test of what a new connection would face. All figures were read on 1 Nov 2026.
Find the Network
Search the town, then let the map load the network operator's layers: substations, transmission lines and existing generation.
- Broken Hill 220/22 kV terminal station
- The 220 kV X2 line south to Buronga Switch
- Silverton wind farm to the north-west
- Analyst plan, US$75/month
Read the Constraint Headroom
Open Grid Constraints and select the path. The X2 line maps to constraint equation N>NIL_X2.
- 36.3% of the limit, headroom 260.5, band “loose” at 9:35 pm AEST
- Mean 13.9% over 3,871 five-minute intervals, 19 Oct – 1 Nov 2026
- Peak 53.33% (19 Oct 2026, 10:10 am AEST); history back to January 2024
- Pro
See Which Constraints Bind on the Units Already There
X2 itself ran loose, but the units at Broken Hill were still constrained: by their own connection and transformer limits and by wider-area constraints.
- Broken Hill Solar Farm: proving constraints include N>NIL_BHTX_LV, N_BROKENHSF_FLT_30 and N_BROKENH1_0INV
- Plus frequency control constraints such as F_I+TTS_TG_R5 and F_MAIN+TTS_TG_R60
- Pro
Measure Curtailment Nearby
Curtailment by Cause, NSW1 region, the 30 market days to 31 Oct 2026.
- Broken Hill Solar Farm: 839.1 MWh curtailed of 9,652.5 MWh available (8.7%), all network-caused, A$54,671 at the regional price
- Silverton Wind Farm: 388.1 MWh (1.1%), network-caused, A$17,552
- Pro
Check the Outages
Network Outage Constraint Sets shows every scheduled outage linked to a constraint set, seven days back and 90 ahead.
- 222 constraint sets and 687 schedule records in the window, 1 Nov 2026
- Buronga lines 6C, 6G and 6H: outage set N-X_6C_6G_6H, scheduled to end 4 Nov 2026, 06:00 AEST
- Pro; unit risk via API
Apply the Loss Factor
The published loss factor turns the regional price into what a unit at this connection point is actually paid for energy.
- BROKENH1 2026-27 loss factor 0.8436; STWF1 0.896
- October 2026: A$670,588.78 without the factor, A$565,708.70 with it (-15.6%)
- Pro, available via API
What This Screen Tells a Developer About Broken Hill
The 220 kV line out of Broken Hill ran well inside its constraint limit over the last fortnight. The existing solar farm was still curtailed 8.7% of its available energy in October by network constraints local to its own connection, and every MWh it sells is scaled by a 0.8436 loss factor, a 15.6% haircut against the regional price. A new project here would face the same loss-factor geography, which is the first question for its connection enquiry.
