Australia's wind and solar hit 4.6 TWh in May despite the grid's worst renewables drought since 2022

Australia's wind and solar hit 4.6 TWh in May despite the grid's worst renewables drought since 2022 Record state-level output in a weak-resource month kept downward pressure on east-coast spot power prices, reinforcing the bearish read on Australian generation. Australia's large-scale solar and wind assets produced 4.6 terawatt-hours in May, Rystad Energy reported on Wednesday (2026-06-03), up 10 per cent from 4.2 TWh in the same month a year earlier.⁴ The detail that should catch a trader's eye is what it took to get there. On Rystad's reckoning, May 2026 was the worst wind and solar drought on the National Electricity Market since 2022, and yet output still climbed and four state-level generation records fell.⁴ That matters because it tells you the growth is coming from steel in the ground, not from a kind month of weather. When capacity is rising fast enough to set records in a poor resource month, the floor under renewable supply keeps lifting regardless of conditions. RenewEconomy, citing the same Rystad data, noted that solar and wind continued to push down spot prices and that batteries kept smoothing volatility.⁴ Victoria led the country, with 1,218 GWh of combined utility solar and wind, including 1,079 GWh from wind and 139 GWh from utility PV.⁴ The state's 1,079 GWh wind figure was itself a May record, matched by a record in Queensland at 625 GWh.⁴ These are not marginal beats. They are records logged in a month Rystad describes as resource-starved, which is the point.⁴ The asset-level picture shows where the strongest performers sit. Rystad's top wind capacity factor for the month went to the 175 MW White Rock Wind Farm at Glen Innes in New South Wales, at 45.6 per cent.⁴ Western Australia featured heavily, with Synergy's co-owned 55 MW Mumbida farm at 44.6 per cent and APA Group's Badgingarra at 43.6 per cent.⁴ On the solar side the best assets were almost all in Queensland, led by Pacific Blue's 100 MW Haughton Stage 1 in the Burdekin at 24.3 per cent AC capacity factor, with the 110 MW Moura farm close behind.⁴ The trade read here is bearish for east-coast thermal generation and the prices it sets. More zero-marginal-cost supply, even in a weak wind month, erodes the hours in which gas and coal plant set the price. Batteries doing the smoothing work compress the volatility that peakers rely on to earn. The consensus across the packet runs bearish on Australian power, at roughly 47 per cent strength, and the May data does nothing to challenge that.⁴ The wider context is a renewables surge showing up everywhere the data is collected. EU renewable generation hit a record 384.9 TWh in the first quarter, 14.5 per cent above a year earlier, with Q1 solar at 52.6 TWh, also a record, Montel's EnAppSys data showed.¹ Globally, the IEA reckons solar met more than a quarter of new energy demand last year, and renewables produced more electricity (34 per cent) than coal (33 per cent) for the first time in over a century.³ Australia's May figures are one national reading of the same trend. What is not resolved is demand. The forecasts that matter most over the next decade point to data-centre load that could absorb much of this new supply. The EIA projects server electricity consumption alone reaching between 446 and 818 billion kWh by 2050.² If that demand lands faster than build-out, the bearish spot story weakens.² The next signal to watch is whether June's resource conditions normalise and what that does to records set in a drought month. A weak-wind May still beat last year; an average June should beat it more comfortably, and the question is how far spot prices fall when it does.⁴ Watch the battery dispatch alongside it, because that is what now decides whether the cheap midday floods through to the evening peak.⁴
