Your project is funded. The network is ready. The connection shouldn’t be the hard part.
AMMS builds standardised injection, withdrawal and blending skids for gas transmission and distribution connections in the sub-petajoule range — so smaller producers and users get a proven, repeatable unit instead of a bespoke engineering bill.
“Enabling cost-effective gas infrastructure access for renewable gas producers and small gas users is exactly why AMMS was created.”
— AMMS, on supplying the SA1 Salisbury Bioenergy PlantRenewable gas has stopped being a pilot. Every funded project now needs a connection.
Three public signals, one consequence: a pipeline of Australian projects that all reach the same milestone — first gas into the network.
GreenPower’s Renewable Gas Certification is live
Grid-injected biomethane now earns tradeable renewable gas certificates — turning injection from a compliance exercise into a revenue line.
Governments are funding producers directly
The NSW Renewable Gas Production Program and ARENA grants — including $6.08 million to the SA1 Salisbury plant — are moving projects from feasibility to construction.
Grid injection is proven in Australia
Malabar in Sydney showed biomethane flowing into a distribution network. SA1 in Adelaide is next. The question has shifted from whether to how affordably.
The bottleneck is the connection. A bespoke grid entry design can cost more than a small producer’s margin can carry. AMMS exists to take that line item off the critical path — with standardised units, engineered once, delivered repeatably.
Two sides of the meter. One standard way in.
Producers putting gas into the network
Biomethane and renewable gas projects that need custody transfer metering, pressure control and gas quality management at the injection point.
- High and low pressure injection skids
- Custody transfer and process safety compliance built in
- Selected for the SA1 Salisbury Bioenergy Plant
Users taking gas from the network
Industrial and commercial sites in the sub-petajoule range that need a new offtake connection without a bespoke engineering program.
- High and low pressure withdrawal skids
- Standardised design, repeatable delivery
- Local engineers through commissioning and beyond

Australia’s flagship renewable gas project will flow through an AMMS skid.
AMMS was selected by Delorean Corporation to supply a Low-Pressure Injection Skid for the SA1 Salisbury Bioenergy Plant in Adelaide.
The job: facilitate custody transfer of biomethane from SA1 into the Australian Gas Infrastructure Group (AGIG) distribution network in South Australia — the commercial gateway between the plant and the grid.
The plant: SA1 converts commercial and industrial food waste into mains-grade biomethane, generating Renewable Gas Guarantees of Origin certificates under GreenPower’s certification scheme.
Why it matters: every certificate SA1 earns will pass through the injection point. The metering skid isn’t a component — it’s where renewable gas becomes revenue.

Infrastructure is bought from people, not brochures.
When you call AMMS you speak to the engineers and managers who design, deliver and stand behind the unit — by name, from first enquiry through commissioning.

Grid injection, step by step: what a biomethane producer needs before first gas
The path from upgraded biogas to network injection — and where the timeline usually slips.
Read the draft
By the time a biomethane project is funded, the hard engineering questions feel answered: feedstock, digestion, upgrading. Then the connection process starts, and a new set of questions arrives that has nothing to do with making gas and everything to do with selling it.
1. The network operator sets the specification
Your gas enters someone else’s asset. The network operator’s gas quality requirements, pressure regime and connection process govern the design — and engaging them early is the single biggest schedule protection available to a producer.
2. The connection agreement defines the commercial boundary
Where custody transfers, how energy is measured, and who owns which flange are contractual questions with engineering consequences. The metering point is where your product becomes their throughput — and where your revenue is counted.
3. The grid entry unit does the work
Metering to custody transfer standard, pressure control, quality monitoring and protection — packaged at the injection point. This is the equipment decision, and the choice is between a bespoke design engineered from scratch or a standardised unit already proven against network requirements.
4. Certification turns molecules into revenue
Under GreenPower’s Renewable Gas Certification scheme, injected biomethane generates certificates — but only what is properly measured at the custody transfer point is counted. Metering integrity is certificate integrity.
The pattern across Australian projects is consistent: the connection is rarely the most expensive part of a project, but it is the part most likely to sit on the critical path at the end, when there is no schedule left to give.
Custody transfer for renewable gas: why the meter is the money
What “custody transfer” actually obliges you to do, and why it’s treated differently from every other measurement on site.
Read the draft
Most instruments on a gas site inform decisions. One instrument settles money. The custody transfer meter is the cash register of a gas project: every joule that crosses it is bought, sold, or certified on its word.
Why custody transfer metering is different
Because two parties settle against it, custody transfer measurement carries obligations ordinary process metering never faces: agreed accuracy, verifiable calibration, and equipment both sides — producer and network — can trust without argument.
What that means at the injection point
The measurement system, the gas quality analysis and the pressure control all have to hold up commercially, not just operationally. A dispute at the custody transfer point isn’t an engineering inconvenience — it’s an invoice dispute.
The renewable gas twist
Certification schemes add a third party to the transaction: the certificate registry. For a biomethane producer, the custody transfer point now underwrites two revenue streams — the gas and the certificates — which makes getting it right once, to a proven standard, worth more than ever.
