NEM Local Temperature
AEMO issues market notices when forecast temperatures exceed regional reference temperatures in NEM regions like Brisbane, Sydney, Melbourne, Adelaide, George Town, and more. The process includes selecting weather stations, determining alert levels, and issuing market notices based on forecast temperatures. Tasmania's alerts are based on Basslink transfer capability. Specific weather stations and local temperature alert levels are identified for various regions to help manage generation capacities effectively.
