The Golden Beach Energy Storage Project (Project) involves the development of the Golden Beach gas field for long term use as a storage facility – storing domestic gas in times of low demand and supplying this stored gas to the domestic market in times of high demand.

The Project will initially deliver natural gas into the domestic market for a period of approximately 12 months and will then transition to providing stored gas to the market.

View the map of the project.

The Project is aiming to commence providing gas into the domestic market by winter 2028, with storage commencing during 2029.

Construction operations - both on and offshore - will commence in mid 2026 and run through 2027 with the drilling of production wells scheduled to commence in January 2027. Onshore work on the pipeline and gas compression facilities is expected in June 2026.

GB Energy has completed an extensive number of environmental studies through the Environment Effects Statement (EES) process that was conducted from 2019 to 2021. This process was assessed favourably and the impact of the Project through construction and operation will be managed in line with all this work.

In addition, by being able to provide on-demand or dispatchable energy, the Project will provide significant support for the transition to renewable energy. This is done by providing energy at times when wind or solar conditions are not favourable for power production.

GB Energy is an independent Australian energy company, with its head office located in Melbourne.

It is not listed on the ASX or any other stock exchange but has a base of sophisticated and knowledgeable investors.

Our team has a deep understanding of the Eastern Australian energy markets and considerable experience in developing major energy infrastructure projects.

We have embarked on a project information program which involves regular face-to-face meetings with stakeholders. We will look to keep the community updated with project information updates and interested members of the community can contact us by phone or email.

There was significant opportunity for formal comment on the Project through the EES process which has been favourably assessed.

GB Energy will continue to be open to feedback and at all key stages of the Project, there will be an opportunity for public comment.

Issues raised by the community will be dealt with by senior executives of GB Energy and may be escalated to the Board of Directors in case a suitable resolution is not found.

The Project is keen to support local community projects and will continue to seek those inputs during our consultations with community groups.

We are also talking with the community about longer-term and sustainable community initiatives.

Gas storage services involve reinjecting natural gas back into the ground during periods where the primary gas producers produce more gas than is required by the market. Then on days where the gas demand is greater than can be met by the producer’s, stored gas is produced to meet the shortfall.

In simple terms, it allows for the development of a more efficient, lower cost system of delivering gas, enhances system security of supply and supports the development of renewable power generating capacity

1. Underground gas storage supports the development of renewable power generating capacity.

The growth of renewable energy, especially wind and solar generated power is displacing high CO2 emitting generation such as coal. The problem with wind and solar is their intermittent nature – the wind does not always blow, and the sun does not always shine.

Short term use of fast start gas fired power generation uses natural gas that has far lower CO2 emissions than coal, is cheaper to build than hydro power, does not require the construction of more dams and has far greater endurance than current battery supply.

Due to the intermittent nature of the renewable sector, underground gas storage facilities are a far more reliable source of contracted gas supply when compared to primary producers who are better placed at selling to base load gas fired power generators.

2. Underground gas storage enhances system security of supply.

Should there be an outage at a primary producer’s facility, underground gas storage provides an alternate source of gas while supply is re-established.

Unlike a primary producer, underground gas storage does not have the long-term underlying resource base, but it can significantly assist in maintaining supply to essential services during unforeseen events.

3. Underground gas storage allows for the development of a more efficient, lower cost system of delivering gas.

The need for gas varies dramatically over the seasons of the year with less gas required in summer and far more required in winter, primarily for heating. Peak demand in Victoria is generally associated with very cold days.

On peak days, we use approximately 50% more gas than we do on an average day and about twice as much gas as we do on low demand days. It is very expensive and inefficient for the gas producing infrastructure (offshore platforms, pipelines and wells) to be sized to meet peak demand, so purpose-built gas storage facilities, capable of very high rates of production are used to meet the shortfall.

This allows primary producers to produce at near constant rates during the year and on days when the primary production is more than market needs, the excess gas is injected into storage. As a result, primary infrastructure is made more efficient and the purpose-built storage facility is fully utilised, reducing the overall cost of delivering gas to the market.

Typically, the seabed architecture is approximately 10m x 10m for a single well. The Project anticipates having three well-heads close together on the seafloor, connected to a hub at the seaward end of the pipeline.

Yes. There will be vessel restrictions around the well-head locations. The position of the well heads and the subsea pipeline will be marked n marine charts.

When drilling is taking place, GB Energy will be seeking a 500m exclusion zone around the drilling rig.

Recreational fishing should not be impacted at any stage.

The Project footprint is small, and all facilities will be designed to minimise potential impacts by having fisher friendly structures protecting them.

We are in frequent dialogue with fishers about the Project and will discuss any concerns they may have and how to minimise them.

The sub-sea architecture will extend approximately 6m above the seabed. This equates to a depth of approximately 14m below sea level.

This will not be known until we complete the pipeline design studies.

Studies conducted in the Project area show the seabed is gently sloping seawards, with a sandy bottom with small banks and gutters.

Closer to the beach there are sporadic small rocky reefs in the adjacent areas. The Project design avoids these reefs.

The installation and operation of the facility is designed to have minimal impact on the environment and amenity. Once the sub-sea equipment is installed there will be no visible signs of the Project.

The pipeline will be drilled or tunnelled under the nearshore and shore crossing area and will not be visible.

GB Energy are developing a Local Content Plan which requires all our contractors to source goods and services locally, wherever possible.

The drilling location will be approximately 3km from the nearest shoreline and will therefore be visible from the beach whilst it is undertaking offshore work.

During the drilling campaign the jack-up rig will be lit at night.

Yes, all drilling rig activities will be conducted in accordance with regulatory approved processes and procedures.

They will also be conducted in accordance with the rig contractors approved standards and our well management system.

Golden Beach is a dry gas field and does not contain oil.

We have in place an oil pollution emergency plan (OPEP) including rapid response deployment capabilities provided by ORCA and other measures which are coordinated with Victorian and Commonwealth response agencies should a spill occur from a service boat or the drilling rig.

Drilling related waste material will be treated in accordance with the regulatory approved Environmental Plan.

All drilling related liquids pumped down the wells and returned to surface will be water based.

Timing is partly dependent on the availability of the rig and other contracted equipment. Current expectation is late 2026 to mid 2027.

No. The project does not involve hydraulic fracturing (fracking) of the reservoir.

Yes, during the final stages of completing the wells a minimum period of flaring is needed to empty the wells of the drilling and completion fluids and to ensure they are operating correctly. There will be timely notifications to the community around intended flaring operations.

The pipeline is likely to be two 18-inch (457mm) internal diameter pipes.

Subject to finalising the route selection work, we expect it will come ashore approximately 3kms south of Golden Beach towards Glomar Beach, possibly at Delray Beach near to an existing wastewater outfall.

The Project development includes a shore crossing that goes under the beach via a trenchless pipe-laying method.

Horizontal directional drilling (HDD) is commonly used with the main operations taking place behind the sand dunes.

Horizontal Directional Drilling and Direct Pipe methods are construction techniques used to enable pipelines to be installed under sensitive or inaccessible areas, in this case the beach and dunes. A conduit is created through which a pipeline can be threaded such that it connects the onshore and the offshore sections with minimal environmental impact.

Once onshore, it will be trenched and buried through to the compressor station then connected into the Victorian Transmission System and/or Eastern Gas Pipeline.

The pipeline is expected to break out of the seafloor 1km to 1.5km beyond the shoreline and have no impact on recreational fishers.

Twin pipelines allows us to better control the gas flows we need to store and produce gas from the field, and to operate pipe-inspection and maintenance machinery.

The detailed design will address the appropriate installation manner to minimise environmental impact. There is an existing Gippsland Water waste-water outfall line easement across this area and GB Energy is looking to install the pipeline adjacent to this in a way that any impact on the area is as short and least invasive as possible. 

A temporary work pad will be constructed across this area to facilitate stringing of the offshore pipeline prior to installation through the shore crossing and ultimately offshore. This pad will also be used to facilitate installation of the onshore pipeline across this area. The onshore pipeline will be trenched and buried. The pipeline will be concrete weight coated in this area for buoyancy control due to the potential high water table at and around Lake Reeve. 

Yes, and we have already been actively engaged with the owners of these properties. 

We will be discussing all matters that concern landowners with the appropriate landowner. 

We have already reached agreement with a number of landowners. 

Yes, these have been completed. We have a Cultural Heritage Management Plan that has been endorsed by GLAWAC as the Traditional Owners representative body for the lands on which the Project is based. This identifies key areas of heritage significance and has informed route and construction methodologies. 

The site will be located on a land site of approximately 500m x 500m, with the facility only approximately 300m x 300m. 

The compressors will be housed in insulated, sound-proof enclosures and have silencers fitted to the exhausts. 

A low pressure enclosed flare is planned for normal gas venting.  

The plant will be located well away from residential areas. 

A site has been identified as part of the EES studies and is consistent with our objectives to ensure the location of the gas compressor station has minimal environmental and social impacts. We have had successful discussions with the landowner of this site. 

Once the field has produced gas for just over a year, it will transition to energy storage operations.

The initial production will create space in the reservoir to store gas. The production will also provide information on reservoir performance that will allow GB Energy to optimise storage operations.

The location of the gas compressor station near Victoria's principal gas supply hub at Longford will enhance efficiency and security of domestic gas supply.

Gas storage facilities are developed in such a way that gas can be easily stored during periods of low demand and promptly produced during periods of peak demand.

Gas power generation is a flexible form of energy supply that in turn supports the development of renewable energy generation, such as wind and solar. Gas fired power generators can run when there is insufficient wind, or sunlight, to make electricity available into the grid.

The volume (amount of gas) and nature (dry gas, no oil) of the gas accumulation has meant that the field has not previously been considered commercially viable.

GB Energy believes that given the objective of an energy storage development, the Project is commercial.

Minimal if any at all.

The Project will produce a negligible amount of gas compared with the total oil and gas (and water) production that has occurred in the Gippsland basin. There is no intention of producing free water. The transition to gas storage, requires gas to remain in place, minimising possible impact to the aquifer.

Yes.

It has been extensively used world-wide for more than 100 years and the technology is well understood.

Victoria has had a commercial gas storage operation in the Otway Basin (Iona) which has been operating safely for 20 years. There are several others in commercial operation here in Australia and hundreds globally.

No. Neither the appraisal well, nor development wells involve hydraulic fracturing (fracking) of the reservoir.

The storage gas will come out of the connected gas market that operates in eastern Australia. Practically speaking the gas is most likely to have been produced in the Gippsland Basin.

No.

The GB Energy Project is totally independent of the CarbonNet project.

The CarbonNet project is sponsored by both the State and Federal governments and relates to the capture and sequestration of Carbon Dioxide (CO2).

They are fundamentally different businesses.

Yes. As a neighbour to our permit area, we communicate with CarbonNet on a regular basis, as we do with all stakeholders in our project.

At times we may share resources and services with CarbonNet where there is the opportunity to minimalize the impact upon our local community and environment.
