Amplitude Energy (ASX:AEL) taps Synertec to fix Orbost’s gas-burn problem

Cutting fuel gas at Orbost frees more molecules for the East Coast market, exactly where AEL needs volume

Amplitude Energy (ASX:AEL) has quietly picked Synertec’s Powerhouse platform to run a power optimisation project at the Orbost Gas Processing Plant in Victoria. The indicative project value sits between A$4.5m and A$5.5m if it reaches Final Investment Decision, so this is not a company-making number in isolation.

But the operational logic matters more than the dollar figure. The plan pairs roughly 2MW of solar with 5MWh of battery storage and advanced controls, sitting alongside Orbost’s existing gas generators. The goal is to run the plant on a single gas generator during normal operations, freeing up gas molecules that today get burned onsite.

For a company sitting on contracted volumes it has not yet drilled up, every unit of fuel gas saved at Orbost is a unit that can be sold into the East Coast market. That reframes what looks like a small engineering announcement into something more strategic.

The FEED study runs through H1 FY27, with construction and integration to follow if AEL green-lights the Final Investment Decision.

Why saving fuel gas at Orbost is worth more than A$5m suggests

Orbost processes Sole gas from the Gippsland Basin and is one of AEL’s core producing assets. The plant currently runs its own gas generators to keep the lights on, which means a portion of everything Sole produces is consumed onsite rather than sold.

Cutting that consumption is a direct margin lever. Every terajoule freed up is a terajoule available for East Coast customers at spot or contracted prices, without drilling a new well. In a market where AEL’s contracted book already runs ahead of proven supply, that is quietly valuable.

It also improves reliability and reduces maintenance, which matters for a facility that anchors the Sole revenue line. Downtime at Orbost hits cash flow immediately.

The context is a company still waiting on the drill bit

AEL’s bigger story remains the East Coast Supply Project. Roughly 50PJ of contracted volume already sits on the books through the EnergyAustralia and AGL deals signed earlier this year, both contingent on drilling success.

After the Isabella disappointment in March that wiped out around A$500m of market value, the pressure on the Juliet and Annie wells later this year is heavy. Investors are watching drilling results, not power projects.

Our take is that the Orbost work is a sensible defensive move while the exploration story plays out. It protects margins on existing production, which is the one part of the business that does not depend on a favourable drill result.

The commercial model is where investors should focus

The FEED study will evaluate two delivery paths. A traditional capital sale where AEL owns the kit, or a Build, Own, Operate and Maintain structure where Synertec keeps the asset on its balance sheet and AEL pays for the service.

BOOM is the more capital-light option and would keep AEL’s ECSP-heavy capex program from getting stretched further. With FY26 capex guidance of A$125m to A$150m already dominated by drilling, a BOOM structure looks like the natural choice.

The FID decision will tell investors how management is thinking about capital allocation between growth and optimisation.

The Investors Takeaway for Amplitude Energy

This announcement will not move the AEL story on its own. The share price will still be driven by the next drilling result and by whether the ECSP contracted volumes get backed by proven reserves.

But it does show management thinking about the levers it can pull without a drill bit. Freeing up fuel gas at Orbost, extending Sole’s operational life and keeping capex disciplined are exactly the moves a producer should be making while the exploration outcome is uncertain.

The Juliet and Annie wells remain the real event risk. Orbost is the sideshow investors should still track.
