Coal exits versus replacement builds: who’s actually ahead

Four gigawatts. That’s roughly the scheduled coal capacity due to leave the NEM between now and 2030 across Eraring, Yallourn and Loy Yang A, against a transmission queue that, on AEMO’s own numbers, is still waiting on several major Renewable Energy Zone links to reach financial close. Put those two facts next to each other […]
State renewable targets compared: the honest scorecard

82 per cent. That’s the renewable share South Australia’s grid has been running at on an annual basis for a while now, and it sits there as the awkward benchmark every other state gets measured against whether it likes it or not. Tasmania claims it got to 100 per cent years ago, on paper, through […]
Will Snowy 2.0 ever earn its keep?

Past $12 billion. That’s the number Snowy Hydro’s owner, the Commonwealth, has to make peace with before anyone can answer the question this piece is asking. Will Snowy 2.0 ever earn its keep? Not “is it a good idea in theory” – that ship sailed around 2017, but will the cash actually come back, on […]
NSW’s coal exit is outrunning its REZ build

Four coal units at Eraring, two at Bayswater, two more at Vales Point. That’s roughly 8,000 megawatts of dispatchable capacity sitting in NSW that the state’s own roadmap assumed would be gone or going by the early 2030s. Some of it already should have been. Origin Energy’s attempt to close Eraring in 2025 got pushed […]
Public versus private ownership of generation: who builds it better

$2.4 billion. That’s roughly what Queensland’s state-owned Stanwell and CleanCo have between them committed to pumped hydro and firming capacity through the Queensland Energy and Jobs Plan, money raised against the state’s own balance sheet rather than a private sponsor’s. Meanwhile Akaysha Energy, backed by BlackRock’s infrastructure arm, has been building battery capacity across three […]
EnergyAustralia: the gentailer counting down to Yallourn’s exit

1,480 megawatts. That’s the hole in Victoria’s supply that opens up when Yallourn shuts in mid-2028, and it’s EnergyAustralia’s problem more than anyone else’s, because EnergyAustralia owns the plant. The company has known the date for years. It locked it in publicly back in 2021, trading an earlier flagged closure for a firmer, later one, […]
Who really pays for the transmission build-out

AEMO’s most recent Integrated System Plan pencils in something north of $20 billion of new transmission by 2050, and that number has already moved twice since the 2022 plan was signed off. Every time it moves, it moves up. The transmission build-out cost is the least discussed big number in the entire energy transition, and […]
Victoria’s SEC revival meets its offshore wind test

A billion dollars of taxpayer equity now sits inside a government-owned energy company headquartered on Commercial Road in Morwell, in the middle of the Latrobe Valley’s coal country. That’s the State Electricity Commission, relaunched by the Andrews government in 2022 after roughly three decades in the wilderness following the Kennett-era privatisations of the 1990s. It’s […]
AGL versus Origin: two gentailer strategies compared

Origin Energy’s market capitalisation sits comfortably past $15 billion. AGL’s has spent most of the past two years struggling to hold above $10 billion. That gap is the whole story, if you’re in a hurry. It tells you which of the country’s two big listed gentailers the market thinks has the better balance sheet under […]
Why wholesale electricity prices swing so violently

South Australia’s spot price sat at the market price cap for a chunk of a hot Tuesday afternoon last month, then dropped below zero before most people had switched the oven on for dinner. Same grid, same day, same set of generators. A swing of roughly $18,000 a megawatt-hour inside twelve hours. Nobody at AEMO […]
