Regional Outlook — NSW1: Monday 20 July 2026
NSW spot price sits at $112.78/MWh at 06:25 AEST, tracking near the top of an overnight range that swung from $30-140/MWh. Prices bottomed around $30-45/MWh between 22:40-00:00 as demand eased below 8,000 MW, then climbed steadily through the morning ramp as demand rebuilt past 9,400 MW. The current level is consistent with the morning demand build-up pattern seen over the past 24 hours, where prices tracked between $80-120/MWh through the evening peak.
Generation mix is currently dominated by black coal at 6,483 MW, with hydro contributing 1,273 MW and batteries delivering 980 MW into the morning ramp. Wind adds 295 MW and solar just 20 MW, reflecting the pre-dawn timing with negligible solar potential (0%) and light wind conditions (6.4 km/h at surface level per current weather readings). Renewable penetration sits at 28.4%, down from an overnight peak of 53.1% reached around 04:00 AEST when wind and hydro carried a larger share of load. Carbon intensity has risen accordingly to 0.630 tCO2/MWh, up from a low of 0.412 tCO2/MWh overnight, tracking the inverse relationship between renewable output and demand-driven coal dispatch.
Predispatch forecasts point to further upside through the morning, with prices climbing to $123.99/MWh by 08:00-11:00 AEST as the demand peak firms, before easing to $85/MWh from midday and settling into the $65-80/MWh band through the afternoon as solar generation lifts. A brief spike to $142.82/MWh is flagged for the 22:00-22:30 window this evening. Overnight, prices are forecast to fall back to $44-55/MWh between 00:00-04:00 AEST tomorrow, consistent with the identified low-carbon load-shifting windows — the 00:00-01:00 window shows the best economics at $44.81/MWh average with a $98/MWh saving versus peak.
No active market notices specific to NSW generation adequacy or network constraints are in effect today. Recent NSW-relevant notices are limited to completed transmission outages (Armidale-Dumaresq 330kV line, Murray-Upper Tumut 330kV line, Directlink cables), all returned to service, and a July 13 non-conformance flag on battery unit LDB
