Roughly 1.1 million customers. A coal station that was supposed to close years ago. A Hong Kong billionaire as ultimate owner. And a retail business that competes in two of Australia’s most price-sensitive markets without making much noise about any of it. That is Alinta Energy in mid-2026, and the honest read is that very few people in the sector have a firm grip on where this company is actually headed.
I’ve been watching Alinta’s moves for a few months now, partly because the company keeps cropping up in conversations about who holds the remaining thermal generation in the NEM, and partly because the Loy Yang B story has quietly become one of the more interesting questions in the Victorian grid.
Who owns Alinta, and why it matters #
Alinta Energy is privately held, ultimately controlled by Chow Tai Fook Enterprises — the Hong Kong conglomerate run by the Cheng family, better known in Australia for jewellery retail than for brown coal. The acquisition was completed back in 2017, when CTF paid roughly $4 billion for the business. That ownership structure matters because Alinta does not file with the ASX, is not subject to the same quarterly disclosure pressure as AGL or Origin, and operates with a degree of commercial opacity that its listed competitors simply do not have. Follow the money and you reach a private family conglomerate with long investment horizons and no particular need to satisfy Australian fund managers at an AGM.
That is not a criticism. It is just a structural fact that shapes how the company makes decisions, and why those decisions can look puzzling from the outside.
Loy Yang B: Australia’s most awkward coal plant #
Alinta owns Loy Yang B in the Latrobe Valley — a 1,000 megawatt brown coal station in Victoria’s east that has been operating since the early 1990s. The plant’s original closure date was flagged as 2047, then brought forward informally, then complicated by the energy crisis of 2022 when every dispatchable megawatt suddenly had political weight again.
The honest read on Loy Yang B is that it is simultaneously too big to ignore and too old to invest in seriously. It sits alongside AGL’s Loy Yang A in the Latrobe Valley, and the Victorian grid’s dependence on both plants has not resolved itself as quickly as AEMO’s earlier modelling suggested. AGL’s own coal exit strategy — which we examined in detail earlier this year — involves replacing capacity with batteries and firming contracts. Alinta faces the same physics but with a less public timeline and no ASX investor base demanding quarterly updates on the replacement plan.
What Alinta has said publicly is that Loy Yang B will close by 2035. That is the committed date under Victoria’s energy planning framework. Whether the economics support running the plant all the way to 2035, or whether a voluntary early closure becomes attractive as the market evolves, is a genuinely open question. The plant has been profitable during high-price periods — wholesale price volatility cuts both ways, and a brown coal generator with low variable costs can capture significant value during demand spikes. But ageing infrastructure and regulatory pressure on emissions will eventually push the numbers the other way.
I’ll admit I got this wrong for a while: I assumed Alinta would be more aggressive about announcing a transition plan. They haven’t been, and given CTF’s investment horizon, they may not need to be.
Gas in Western Australia and the Pilbara #
Away from the NEM, Alinta’s Western Australian operations tell a different story. The company is one of the larger gas retailers and generators in the south-west interconnected system, with the Pinjarra and Wagerup gas plants supplying industrial customers as well as the retail market. Alinta also operates Reeves Plains, a gas-fired plant in South Australia — modest in scale but relevant to the state’s firming picture.
The Pilbara is the more interesting part. Alinta runs an integrated gas and power business serving the mining and resources sector in the region, where off-grid reliability is non-negotiable and the cost of power outages is measured in lost production, not inconvenience. That business has been relatively stable — resources companies sign long-dated contracts, margins are firmer than retail, and the competitive dynamics are nothing like the NEM. It is, in effect, a different business inside the same brand.
There has been movement on renewables integration in the Pilbara. Alinta has flagged solar and storage as part of its longer-term roadmap for that business, which makes commercial sense given the irradiation levels and the falling cost of large-scale solar. Whether that constitutes a genuine transition strategy or a hedge against eventual gas supply tightness is hard to judge from the public record. Probably both.
The retail business: competitive but quiet #
Alinta competes in the retail energy market in Victoria, South Australia, New South Wales, and Western Australia. Its market share is meaningful but not dominant — well behind AGL and Origin in the east, but a genuine presence. The retail strategy has been relatively straightforward: compete on price, offer simple products, avoid the brand complexity that has hampered some rivals.
The Default Market Offer regime, which sets a price ceiling for standing offer customers, continues to shape retail margins across the industry. Alinta, like every other retailer, has had to absorb higher wholesale costs and pass through network charges, whilst competing for cost-conscious customers who are increasingly informed about their options. The company has not made a major marketing push around solar, batteries or electric vehicles in the same way some competitors have — which either reflects strategic discipline or a slower read on where the consumer market is heading. I’d lean toward the former, but I’m open to being wrong on that.
The consumer energy resources landscape is shifting fast enough that any retailer without a clear offer around rooftop solar, home batteries and demand flexibility risks looking flat-footed by the late 2020s. Alinta’s current retail profile skews toward traditional supply rather than the two-way, prosumer model that AEMO’s forecasts now assume will be structurally significant.
Emissions exposure and the Safeguard Mechanism #
Running a brown coal station and a fleet of gas plants means Alinta carries real emissions liability. The Safeguard Mechanism, which covers facilities emitting above 100,000 tonnes of CO₂-equivalent per year, applies to Loy Yang B and is tightening its baselines annually. We covered the Safeguard Mechanism’s industrial impact in some depth — the short version is that the declining baselines mean Alinta will either need to reduce emissions, purchase Australian Carbon Credit Units, or use eligible offsets to stay compliant. The cost of that compliance is not trivial and will increase as the baseline ratchets down toward 2030.
The Clean Energy Regulator publishes facility-level data that shows the scale of Alinta’s exposure. The company has not publicly detailed its ACCUs purchasing strategy, which is consistent with its general reticence around forward-looking disclosures. Privately held company, private decisions.
Where does the transition actually leave Alinta? #
Compare Alinta with the other gentailers operating in the NEM and you notice a structural gap. AGL has announced batteries, signed capacity agreements, and is very publicly managing its coal exit. Origin completed the acquisition of Octopus Energy’s local operations and is betting heavily on the technology platform. Even the smaller retailers have staked out renewable credentials. Alinta’s public positioning on generation investment beyond the existing portfolio has been limited.
That might be strategic patience — waiting until the firming market matures, watching what the Capacity Investment Scheme does to merchant economics before committing capital. The CIS has been reshaping the economics of new generation in ways that are still playing out, and a well-resourced private owner can afford to wait. Or it might reflect genuine uncertainty about where to place the next dollar.
The Pilbara operations point toward one possible answer: a continued focus on contracted, integrated energy supply to industrial customers rather than a big merchant renewables build. That is a defensible position. The resource sector needs power, is willing to pay for reliability, and is increasingly required to account for its own Scope 2 emissions — which makes green power purchase agreements with a trusted local supplier an obvious product.
Follow the money, and CTF’s long-hold private ownership suggests Alinta is not under pressure to make a dramatic announcement. The assets generate cash. Loy Yang B will run until it doesn’t. The gas business is stable. Retail is competitive but functioning. From a pure returns standpoint, the company does not need to rush.
The question that lingers — and it is a genuine one — is whether patient private capital is the right posture for a company this exposed to coal as the Victorian grid moves toward higher renewables penetration and carbon compliance costs compound. By the early 2030s, that calculation could look very different from how it looks today. In cricket terms, you can bat defensively for a long time, but at some point the run rate demands a shot. Alinta’s shot-selection will be worth watching.
