Project EnergyConnect loop flows and negative residues
Since 1 October 2026, Project EnergyConnect has closed a transmission loop between New South Wales, Victoria and South Australia. Physics sets how flow splits around a loop, so when one link is constrained another can carry energy from a high-price region to a cheaper one, earning a negative settlement residue. AEMO's PEC market integration update explains the spring washer pricing behind it.
This page sums AEMO's 5-minute residue on the loop's AC links: Heywood, VNI and PEC. A positive sum means the loop, on net, moved energy from lower to higher prices.
Selected range
- of intervals: net flow low to high price
- of intervals: net negative residue
- net loop residue
- from net-negative intervals
Running total of net loop residue
A rising net line means flow mostly followed price; a falling stretch means counter-price flow won.
Share of each day: net positive vs net negative

AEMO 5-minute dispatch residue, not final settlement. Murraylink (DC, outside the AC loop) is optional. AEMO plans to net residues across the loop from 1 November 2026 (go-live plan).
