Australia Proposes Day-Ahead Market To Reduce Prices
6.0
Mike Jonas proposes that Australia adopt a binding day-ahead auction, by region, to lock most of the following day’s electricity supply and reduce short-term dispatch volatility. He cites international examples such as PJM and Nordic markets showing lower volatility and 10–20% system-cost savings, and argues AEMO could implement the change using existing LP software for an estimated A$20–30 million, with regional pilots possible.
Key Points
- 1Proposes binding day-ahead auctions by region to lock most next-day electricity supply.
- 2Reduces price volatility and system costs; PJM typically clears about 95% demand, saving 10-20%.
- 3Enables better planning, lowers bills; feasible with existing LP tools and AEMO software upgrades.
Scoring Rationale
Practical, evidence-backed market proposal with clear implementation steps, limited by being an opinion piece and non-DS topic.
