The Battery Storage and Grid Integration Program submitted an analysis looking at congestion in the National Electricity Market (NEM) to the Energy Security Board as a response to their Transmission Access Reform Directions paper.
The analysis encompassed every generator that’s been impacted by a transmission constraint since 2019 to get an understanding of the state of congestion in the NEM, and found that:
- The overall volume of curtailed energy in FY22 was less than 0.6% of annual demand, but is not distributed equitably. This is likely lower than many stakeholders expect.
- Renewable generators are being disproportionately impacted, with some having as much as 47% of their annual energy production curtailed.
- The energy being curtailed from these renewable generators is on average much cheaper.
- Several of the worst impacted generators are located outside of the AEMO’s proposed Renewable Energy Zones.
