Regional Outlook — VIC1: Sunday 30 August 2026
Victoria's spot price sits at $95.69/MWh as at 06:30 AEST, tracking near the middle of a volatile 24-hour band that ranged from -$20.00/MWh overnight (04:00 AEST, during minimum demand trough near 2900 MW) to a peak of $134.68/MWh in the early evening system peak. Demand at the current interval reads 6,022 MW, up sharply from the sub-3,000 MW overnight low as morning ramp-up takes hold. The past 24 hours show a classic pattern: negative-to-near-zero prices through the 19:00-05:00 AEST overnight window on soft demand and thin margins, followed by a steep climb from around 06:00 AEST as demand rebuilt past 4,000 MW and gas peaking plant set the price.
Generation mix at the last interval is dominated by brown coal at 4,290 MW, followed by battery storage at 687 MW, gas OCGT at 398 MW, wind at 190 MW, hydro at 51 MW, and solar at 0 MW (pre-dawn). Renewable penetration sits at 16.53%, well down from the overnight peak of around 36% recorded near 06:00 AEST when wind generation was stronger relative to lower demand. Carbon intensity is running at 0.978 tCO2/MWh, down from a midday-to-evening high above 1.13 tCO2/MWh yesterday as coal's share of the mix tightened during peak demand — the current reading reflects some renewable and battery contribution easing the average. Today's weather outlook shows minimal wind potential (0.2%) and modest solar potential (15.7%) for Victoria, suggesting renewable output will stay constrained through the day, keeping carbon intensity elevated into the 1.0-1.15 tCO2/MWh range during solar hours given yesterday's pattern.
Pre-dispatch forecasts point to a firming morning peak, with prices climbing toward $144.48/MWh by 08:00 AEST and holding in the $120-146/MWh band through to around 10:30 AEST as demand ramps into typical Monday commercial and industrial load. Prices then ease steadily across the day, falling to double digits by 14:00 AEST and into single digits or below by mid-afternoon, before AEMO's forecast trough hits deeply negative territory again overnight (-$3.50/MWh forecast for 04:00 AEST tomorrow). Traders should note the identified low-price windows for load-shifting: 02:00-05:30 AEST tomorrow offers average prices between -$3.16/MWh and -$2.09/MWh with zero carbon intensity, representing savings of $142-149/MWh versus peak pricing.
On notices, VIC-specific items are limited to historical contingency reclassifications on the Eildon PS-Mt Beauty 220kV lines (25 August, now cancelled) and an inter-regional transfer limit restoration on the South Morang-Sydenham 500kV line, both administratively closed with no current impact. The most relevant active notice for all NEM participants is AEMO's MarketNet VPN security patching change (CHG0112926), scheduled for 03 September 10:00-15:00 AEST, which may cause brief interruptions to variable VPN connections — no impact expected on today's trading. No active market interventions or non-conformance declarations are currently affecting VIC1.
