Congestion Pricing Mis-pricing Revenue Leak
Definition
Current NEM settlement uses RRP, leading to 'mis-pricing' where generators behind congestion do not capture full locational value differences, distorting income allocation.
Key Findings
- Financial Impact: 10-20% revenue distortion per congested event; e.g., RRP - LMP difference (AUD 50-1000/MWh) x curtailed MW x hours
- Frequency: High frequency in constrained regions (QLD, NSW, VIC); assessed by price deviation magnitude
- Root Cause: Uniform RRP settlement ignores nodal congestion costs; solar bidding exploits limits without true marginal cost exposure
Why This Matters
The Pitch: NEM generators in Australia 🇦🇺 lose 10-20% potential revenue from congestion mis-pricing. Automated LMP/CMM settlement captures full congestion margins.
Affected Stakeholders
Renewable generators, Interconnector operators
