Origin Energy: The Coal Plant, the LNG Cash Machine and the Software Bet

Origin is the most interesting portfolio in Australian energy because it contains a declining asset, a cash machine and a genuine growth option at the same time. The Eraring coal station is winding down. Australia Pacific LNG throws off distributions. Octopus and Kraken are a bet that the future of energy retail is software rather than megawatts. Most utilities have one of these; Origin has all three, and the tension between them is the whole story.

How is Origin structured?

Energy Markets is the largest and most visible business: electricity and gas retailing to millions of Australian customers, supported by generation assets including Eraring, gas peaking plants and an expanding portfolio of grid-scale batteries. It is where consumer price regulation, wholesale volatility and political attention all land.

Australia Pacific LNG is the financial ballast. Origin holds 27.5% of a coal seam gas to LNG project at Gladstone in Queensland, operated in joint venture with ConocoPhillips and Sinopec. It requires little management attention from Origin and delivers substantial cash distributions, which have funded dividends and debt reduction for years.

The Octopus Energy stake is the outlier. Origin invested in the UK retailer and, critically, in Kraken — the customer management and energy orchestration platform Octopus licenses to other utilities worldwide. Origin migrated its own Australian customer base onto Kraken and holds both a licence and an equity interest in the platform’s global growth.

Why did shareholders reject A$18.7 billion?

Because the largest shareholder concluded the price undervalued the parts. A consortium of Brookfield and EIG offered roughly A$9.43 per share in late 2023, with Brookfield taking the energy markets business and EIG taking the LNG interests. The board recommended it. AustralianSuper, holding a substantial stake, publicly stated it considered the offer materially below long-term value and voted against.

The scheme failed to reach the required approval threshold at the December 2023 meeting. The specific argument was that Origin’s Octopus and Kraken exposure was a growth asset the market had not priced, and that APLNG cash flows would be stronger than the offer implied. Brookfield’s counter-argument was that the transition would require capital that public markets would not fund patiently.

Both propositions remain untested, which is what makes the case instructive. A superannuation fund with a thirty-year horizon and an infrastructure buyer with a ten-year horizon reached different conclusions about the same assets, and the outcome was determined by ownership concentration rather than by analysis.

What is the Eraring problem?

Eraring is Australia’s largest coal-fired generator at 2,880 megawatts and has historically supplied a fifth to a quarter of New South Wales electricity. Origin announced in 2022 that it would close the plant several years earlier than previously scheduled, citing the economics of running baseload coal in a market with abundant midday solar.

The New South Wales government responded with an underwriting arrangement designed to keep the plant available while replacement capacity is built, and retirement is now scheduled for April 2029. Origin secured coal supply from the Myuna Colliery through to December 2028 to support that timetable.

The commercial logic on both sides is sound and the policy implication is uncomfortable. A generator whose economics no longer work is being kept open by public money because the replacement capacity is not ready. That is a reliability decision, not a climate one, and it will recur at every major closure until firming capacity is built ahead of schedule rather than behind it.

Why does the Octopus and Kraken stake matter?

Because it is a bet that the defensible position in energy retail is the software layer rather than the customer contract. Kraken handles billing, customer service, tariff design and increasingly the orchestration of distributed assets — home batteries, electric vehicles, solar and demand response — and it is licensed to utilities across multiple countries.

For Origin, the immediate benefit is cost-to-serve. Migrating millions of Australian accounts onto a modern platform reduces the operating cost of retail and enables product designs that legacy billing systems cannot support. The strategic benefit is optionality: if Kraken continues scaling globally, Origin holds equity in a technology business inside a utility.

It also changes the shape of the transition. A retailer with a modern orchestration platform can aggregate thousands of household batteries into a virtual power plant and dispatch them like a generator. That is a materially different business model from owning a coal station, and it requires software capability rather than capital expenditure — which is precisely why Origin’s largest shareholder valued it so highly. Compare with AGL’s asset-heavy approach to the same transition.

What is Origin investing in now?

Storage, mostly, and at pace. Origin delivered its first Eraring battery on time and within budget and has progressed a second, alongside projects at Supernode in Queensland and Mortlake in Victoria. Group capital expenditure guidance has run in the range of A$900 million to A$1.1 billion, with the extension of the second Eraring battery among the drivers.

The site logic mirrors AGL’s. Batteries built at existing thermal generation sites inherit grid connections, land, workforce and approvals, which is why almost every announced large battery in the National Electricity Market is co-located with a coal or gas plant. The transmission network, not the technology, is the binding constraint.

Origin has also continued to invest around its gas position, committing further capital to the Golden Beach gas storage project to strengthen its east coast portfolio, while divesting its Beetaloo Basin interest to Tamboran. Storage rather than new production is the emphasis — a reasonable read of a market where the problem is increasingly seasonal supply timing rather than total reserves. Our guide to the east coast gas shortfall explains why.

What is a virtual power plant and why does Origin care?

A virtual power plant aggregates thousands of household batteries, solar systems, hot water units and electric vehicle chargers and dispatches them collectively as if they were a single generator. Origin operates one of the largest in Australia, and the strategic value is that it provides firming capacity without building anything.

The economics are attractive because the capital is provided by customers. A household buys a battery for its own reasons; the retailer pays for the right to dispatch some of its capacity at peak times. The retailer gets a peaking resource at a fraction of the cost of a gas turbine, and the customer gets a payment that improves their own investment case.

This is where the Kraken platform becomes strategic rather than administrative. Orchestrating tens of thousands of devices in real time, settling payments, respecting customer preferences and bidding the aggregate into the wholesale market is a software problem. Utilities that treat their customer platform as a billing system will not be able to do it; those that treat it as a control system will.

How should investors weigh the three businesses?

Separately, because they are driven by unrelated variables. APLNG earnings track oil-linked LNG contract prices and Queensland coal seam gas production, and they are essentially independent of anything happening in Australian electricity. Energy Markets tracks wholesale electricity spreads, retail competition and regulated price caps.

The Octopus stake is the hardest to value because it is an unlisted growth asset inside a utility. Its worth depends on Kraken’s global licensing trajectory, which is a software valuation exercise rather than an energy one. That mismatch — a technology multiple embedded in a business the market prices as a utility — is exactly what AustralianSuper argued the Brookfield offer failed to capture.

For anyone building a sum-of-the-parts model, the honest conclusion is that the value depends almost entirely on the Octopus assumption, and reasonable analysts differ by billions. That uncertainty is why the takeover became contested rather than routine.

Why does coal seam gas make Origin’s LNG different?

Because the feedstock is produced from thousands of shallow wells across a large area rather than from a handful of offshore platforms. Coal seam gas requires continuous drilling to maintain production, which means APLNG carries an ongoing capital and operational burden that a conventional offshore field does not.

It also creates a permanent land-use interface. Wells sit on farmland, require water management because coal seams produce large volumes of associated water, and depend on landholder access agreements. The social licence issues that attach to coal seam gas are entirely different from those attaching to offshore gas, and they are local, continuous and politically sensitive.

The offsetting advantage is flexibility. A coal seam gas field can be scaled up or down by adjusting the drilling programme, and the same wells can supply either the LNG trains or the domestic east coast market depending on where the value is. That optionality is exactly what makes Queensland coal seam gas producers so central to the domestic supply balance.

A final consideration is franking. Origin, like most large Australian corporates, pays fully franked dividends, and a takeover by an unlisted infrastructure consortium would have ended that stream for domestic shareholders. Franking credits are worth materially more to Australian superannuation funds and retail investors than to foreign buyers, which systematically widens the gap between what an offshore acquirer can pay and what a domestic institution believes the asset is worth. That asymmetry shapes the outcome of almost every large Australian take-private.
