Delorean’s (ASX:DEL) SA1 bioenergy facility is 75% complete and has a startup date locked in!

First gas into Adelaide’s network in November pivots DEL from contractor to infrastructure owner.

Delorean Corporation (ASX:DEL) says construction of its SA1 Salisbury bioenergy facility in South Australia is now 75% complete, with first biomethane injection into the Adelaide gas network scheduled for November 2026. Waste acceptance is pencilled in for August.

On the surface this is a construction update. The more important read is that DEL is about three quarters of the way through becoming a different kind of company. Until now it has built bioenergy plants for other people, most recently for Yarra Valley Water. SA1 is the first one it owns end to end.

That distinction matters because it changes the revenue model. Engineering revenue is lumpy and project-based. An owned facility throws off a long-tail mix of biomethane offtake payments from Origin Energy, gate fees on 70,000 tonnes a year of organic waste, food-grade liquid CO2 sales, plus carbon credits and renewable gas certificates.

It is also the template the company says NSW1 and VIC1 will follow into construction this calendar year. So SA1 is not just a plant. It is the proof point investors need before they underwrite the rollout.

The six revenue streams behind one facility

SA1 is designed to produce 210 terajoules a year of renewable gas and 6,000 tonnes of biogenic liquid CO2. On top of that it generates Australian Carbon Credit Units, Renewable Gas Guarantee of Origin certificates, a biofertiliser by-product, and gate fees on the incoming waste.

Six revenue streams from one site is unusual for a small-cap infrastructure name. It also means the project is not solely exposed to the gas price. The carbon credit and renewable gas certificate markets are growing as Australian corporates chase Scope 1 emissions cuts, and food-grade CO2 has its own tight domestic market.

We think the certificate stack is the line investors are underestimating. The biomethane offtake to Origin gets the headline, but RGGOs and ACCUs are where the optionality sits if pricing tightens.

Why the November date is the only one that counts now

Civil works are substantially done, the asphalt is laid, major mechanical equipment is installed and the Low-Pressure Injection Skid is ready for delivery. Electrical installation starts mid-June. Zero lost-time injuries to date.

These are all the right markers for a project tracking to plan. The risk window now narrows to commissioning, gas network connection sign-off with AGIG, and the GreenPower accreditation pathway running in parallel.

Our concern is the gap between accepting waste in August and first gas injection in November. Three months of feedstock processing without gas revenue is not unusual for anaerobic digestion ramp-up, but it does mean the cash flow story does not start until late in the calendar year.

SA1 as a template, not a one-off

The strategic point management keeps hammering is that SA1 is replicable. Same capacity, same feedstock mix, same product slate. NSW1 and VIC1 are described as shovel-ready and slated to enter construction this calendar year.

If SA1 commissions on time and on budget, the financing conversation for the next two facilities becomes materially easier. Project finance lenders price templated infrastructure differently from one-offs. The skeptical read is that until SA1 actually injects gas in November, the template claim is a forecast, not a fact.

The Investors Takeaway for Delorean Corporation

The next six months are the most important stretch in Delorean’s history as a listed company. Acceptance of waste in August, biomethane injection in November, and a clean commissioning run are the events that turn SA1 from a construction project into an operating infrastructure asset with a multi-decade revenue tail.

For DEL specifically, the milestones to mark in the diary are the August waste acceptance announcement and any update on NSW1 or VIC1 reaching financial close before then.
