regional tas — TAS1
Tasmania's spot price sits at $99.07/MWh at 18:15 AEST, a notable step up from the $80–88/MWh range that dominated the early hours of today and well above the mid-day trough where prices briefly fell into the $39–$55/MWh band during the 21:00–23:00 UTC window. The 24-hour price profile shows a clear evening ramp, with prices climbing through the $96–$106/MWh corridor from around 15:00 AEST onwards and peaking at $124/MWh in one interval overnight. The current $99.07/MWh sits at the lower end of that elevated evening range, suggesting some easing from the overnight peak but prices remain firm as morning demand builds toward 929 MW.
The generation mix is entirely renewable — hydro is contributing 349 MW and wind 36 MW, with gas OCGT sitting at zero. Carbon intensity registers 0 tCO2/MWh and renewable penetration is 100%, a position Tasmania has held consistently across the entire recorded history in this dataset. This is structurally normal for the island given its hydro-dominated fleet, and no gas dispatch has been required across the observation window. With wind potential scoring just 0.3 out of 1.0 and wind speed at only 5.9 km/h, wind output is minimal today — the grid is running almost exclusively on hydro storage dispatch.
No predispatch forecasts or market notices are active for TAS1 at this time, which limits forward visibility on price trajectory. Based on the price pattern observed across the prior 24 hours — sustained $96–$106/MWh pricing through the morning and early afternoon, with a mid-day solar-driven softening toward $50–$70/MWh — expect prices to ease as demand tapers on a Sunday and solar penetration from Victoria and South Australia weighs on interconnected prices via Basslink. Heating demand scores 5.7 at 12.3°C with 59% cloud cover, supporting moderate baseline load through the morning but no demand spike is evident.
Grid stress scores 63/100, with price stability at 41.2/100 reflecting the volatility seen across overnight intervals. The renewable penetration score of 19.5/100 is a gridIQ composite metric and does not reflect Tasmania's actual 100% renewable generation — it scores relative to system-wide NEM conditions. For emissions accounting purposes, Tasmanian consumption carries 0 tCO2/MWh, making this grid among the cleanest procurement opportunities in the NEM today.
