Roughly $4 billion. That is the combined capital expenditure both companies have flagged for their respective transition programmes over the next few years, and yet AGL and Origin are deploying it in ways that look, on close inspection, almost opposite to each other. Same regulatory environment, same NEM, same rising wholesale prices — different calls.
I’ve been watching this divergence play out for the better part of two years now, and the honest read is that the market hasn’t fully priced what it means for either stock, or for consumers caught in the middle of both strategies.
How each company got here #
Start with the balance sheets, because they explain everything downstream.
AGL spent a painful few years post-2021 fighting off Mike Cannon-Brookes’ demerger campaign, eventually abandoning the split of AGL Australia from Accel Energy and installing a new board under Graeme Hunt. That fight was costly in management attention and market credibility. What came out the other side was a company that resolved — loudly and publicly — to keep its thermal generation assets running longer than many analysts expected, whilst simultaneously pushing into batteries, demand flexibility and a retail customer base it now describes as its primary moat.
Origin’s path was different. The failed Brookfield-led acquisition attempt in 2023 left Origin independent but sharper about what it actually wanted to be. It has since leaned harder into Octopus Energy — Origin holds a significant stake in the UK-based technology platform — and has been more willing to talk about accelerating coal exit at Eraring, Australia’s largest coal-fired power station on the NSW central coast, even as it negotiated with the NSW government about keeping lights on through the transition period. Eraring’s extended life beyond its original 2025 closure date was always a market-driven decision dressed up as a reliability one, and Origin has been relatively candid about that tension.
The generation portfolio question #
AGL still operates Loy Yang A in Victoria’s Latrobe Valley, Bayswater in the Hunter Valley, and a collection of gas peakers. Follow the money here and you find a company that is betting — not unreasonably — that firming capacity will command a premium as renewables penetration deepens and AEMO’s Integrated System Plan projections for dispatchable generation shortfalls prove accurate. The AGL thesis is essentially: our thermal plant is a liability on a thirty-year horizon but a very valuable asset on a five-year one, so let’s extract maximum value while simultaneously building the replacement.
That is not a crazy position. But it requires the wholesale market to keep rewarding dispatchable generation, which is far from guaranteed in a market that the AEMO Integrated System Plan expects to be substantially reshaped by new transmission, distributed storage, and offshore wind during this decade.
Origin’s generation story is cleaner in one sense and murkier in another. Eraring’s extended life created cash flow it has been partly channelling into batteries and renewables contracting, but the company hasn’t built owned-generation renewables at the scale some investors expected. Its power purchase agreement strategy is sensible risk management, but it does mean Origin’s renewable credentials rest partly on paper rather than on steel in the ground.
On big batteries specifically, neither company has moved as decisively as pure-play developers. For comparison, see what BlackRock-backed Akaysha Energy has been doing — their pipeline dwarfs what either gentailer has committed to in owned storage. You can read the detail in our piece on Akaysha Energy and BlackRock’s battery bet on the NEM.
AGL versus Origin on the retail front #
This is where it gets genuinely interesting.
AGL has roughly 4.5 million customer accounts — electricity, gas, and broadband bundled — making it the largest energy retailer in Australia by customer count. It has been investing in smart home technology, virtual power plants and EV charging infrastructure on the premise that the customer relationship is the long-term business, and the commodity electrons are just the entry point. The Kaluza platform (acquired from OVO Energy) is the technology backbone for that ambition. Whether Kaluza at scale in Australia delivers what it promises in the UK is an open question; the honest read is that Australian network structures and the Default Market Offer regime create headwinds the UK playbook didn’t face. For context on how the DMO affects retail margin, our explainer on the Default Market Offer and your power bill covers the mechanics.
Origin’s retail technology bet is on Octopus. The Octopus platform is genuinely impressive — it has demonstrated in the UK and Germany that time-of-use tariffs and smart dispatch can reduce customer bills and improve grid outcomes simultaneously. Origin’s pitch is that it will bring that capability to Australia at scale. The challenge is that Australian rooftop solar penetration is unlike anything Octopus has operated in, and our network tariff structures are only slowly moving toward the real-time pricing that makes the Octopus model sing. We’ve written about that solar-pricing tension before — see why electricity pricing needs to be reformed.
The gas exposure problem neither can escape #
Both companies carry gas retail and, in AGL’s case, gas-fired generation. This is increasingly awkward.
Gas prices in eastern Australia remain structurally elevated following the disruptions of 2022, and while the federal government’s gas price cap mechanism provided some relief, the underlying supply tightness hasn’t resolved. For residential customers, gas is becoming the expensive option; for industrial customers, it’s a sovereign risk question. AGL and Origin both face the prospect of accelerating gas customer churn as heat pump uptake grows and new housing construction defaults to all-electric. Neither company has a compelling public narrative about what their gas retail books look like in a decade.
I’ll admit this is the part of both strategies I find least convincing. They talk about gas as a transition fuel with the confidence of people who haven’t checked the electrification curve recently.
Capital allocation: who is punting on what #
AGL’s announced capital programmes have emphasised grid-scale batteries, demand response, and customer technology. It joined the Capacity Investment Scheme tender rounds — the CIS being the federal government’s mechanism for underwriting new firm and renewable capacity — though the scheme’s design raises questions about whether it genuinely supports new entrants or entrenches incumbents. We’ve covered that debate in our piece on whether the CIS is quietly picking winners.
Origin has been more active in long-duration contracting and has talked publicly about hydrogen as a future export and domestic firming option, though its hydrogen commitments remain at the feasibility stage rather than the construction stage. The company’s Beetaloo Basin gas exploration interests — held through Beetaloo joint ventures — sit awkwardly alongside its decarbonisation messaging, and the Australian Energy Regulator has been watching the broader sector for misleading sustainability claims with increasing attention.
Follow the money and what you see is AGL betting on customer technology and firming assets, Origin betting on a software platform and contracted renewables. One is a hardware play, the other is a software play, and both are hoping the transition moves at a pace that suits their timeline.
The workforce and community angle #
Worth saying plainly: both companies operate in communities where thousands of jobs depend on decisions made in Sydney boardrooms. Loy Yang A employs a significant number of people in the Latrobe Valley. Eraring employs workers in Lake Macquarie. The transition timelines AGL and Origin announce have human consequences that don’t always feature prominently in investor presentations. The Queensland government has been more direct about this — its public ownership model for energy assets is explicitly framed around workforce outcomes, as we covered in the piece on Queensland’s energy plan. AGL and Origin don’t have that option; they answer to shareholders.
The verdict — and I’ll commit to one #
The consensus view seems to be that Origin’s Octopus bet is the smarter long-term play because software margins beat commodity margins. I’m not sure that’s wrong, but I think it’s too early and too tidy.
My read: AGL’s strategy is more internally consistent right now. Keeping thermal assets for near-term cash flow whilst investing in customer technology and storage is coherent — it doesn’t require the market structure to change faster than it actually will. Origin’s strategy is more elegant on paper but depends on Australian pricing reform arriving before Octopus’s first-mover advantage erodes, and on Eraring’s exit not creating a gap in Origin’s generation portfolio that PPAs can’t fully cover. That’s a lot of moving parts to land simultaneously. It’s a bit like picking a batting order when you don’t know the pitch conditions — looks convincing in the rooms, different story once play starts.
Neither company is obviously winning the transition right now. Both are doing the hard yards of managing legacy assets whilst building something new, which is genuinely difficult and deserves more credit than either gets from a market that wants clean narratives. But if I had to choose which strategy ages better over the next five years, I’d lean AGL — not because it’s bolder, but because it’s more honest about what the next five years actually look like.
