1414 Degrees launches EOI for $350–550M grid-scale solar and battery storage platform
1414 Degrees (ASX: 14D) has launched an Expressions of Interest (EOI) process to attract strategic funding and development partners for Stage One of the Aurora Energy Precinct, a large-scale renewable energy platform in South Australia. Stage One targets approximately 70 MW of firm renewable power, drawn from a scalable 140 MW Battery Energy Storage System (BESS) and 70 MW of solar photovoltaic (PV) generation, with indicative development capital of A$350–550 million (approximately US$250–400 million). The EOI follows the Company’s earlier agreement to acquire 100% of SiliconAurora Pty Ltd and marks the next phase of the Aurora project’s development.

Stage One highlights: what’s on the table for partners
Four investment highlights characterise the Stage One opportunity:
- Late-stage and de-risked: Australian Energy Market Operator (AEMO) 5.3.4 / Generator Performance Standards approval has been secured for the initial 140 MW BESS and 70 MW solar PV project.
- Strategic grid and fibre position: The site is located immediately adjacent to a 275 kV transmission corridor and two fibre-optic lines, supporting mining and regional growth.
- Strategic offtake optionality: Renewable-powered industrial and behind-the-meter applications provide multiple routes to monetisation across mining, data centres, and other high-intensity energy users.
- Significant expansion runway: Successful partner(s) receive first rights to the full 1,580 ha precinct, with an indicative pathway to up to 2 GW of PV potential and up to 1 GW of firm renewable capacity.
AI data centre demand at Aurora has already produced a concrete commercial signal: a Heads of Agreement signed in July 2026 for up to 1 GW of data centre capacity, with an existing 33kV power connection enabling an indicative 17 MW starter campus ahead of the larger grid milestone.
The table below summarises the key Stage One specifications drawn from the announcement:
| Development Area | Stage One Capacity | Grid Connection | Regulatory Status | Stage One Capex |
|---|---|---|---|---|
| 1,580 ha (full precinct, long-term Government/Crown lease) | 140 MW BESS + 70 MW solar PV | Adjacent 275 kV transmission corridor | AEMO 5.3.4 / Generator Performance Standards approval secured | A$350–550M (US$250–400M) |
Understanding the Aurora Energy Precinct and why location matters
The Aurora Energy Precinct is an approximately 16 km² development site located 25 km north of Port Augusta, South Australia, held under a long-term Government/Crown lease. The site is directly adjacent to a 275 kV transmission corridor and a fibre-optic infrastructure corridor, placing it at a genuine strategic intersection of power transmission and data connectivity.
The Aurora Energy Precinct acquisition, which saw 1414 Degrees consolidate 100% ownership for $350,000 and remove a joint venture structure that had previously complicated direct financing and customer engagement, set the foundation for the EOI process now underway.
For investors unfamiliar with the terminology, “firm renewable power” refers to renewable electricity generation that is backed by storage capacity, in this case the BESS component, so that power can be dispatched reliably on demand rather than only when the sun is shining. This firmed capacity is considerably more commercially valuable than unfirmed solar generation alone, as it can meet the baseload and on-demand requirements of industrial customers.
The transmission line adjacency is a practical advantage, not just a geographic one. The 275 kV corridor connects BHP operations to the north with the National Electricity Market at Port Augusta, meaning Aurora sits along an existing, high-capacity infrastructure route already serving major industrial demand.
The target customer base for Aurora’s output is industrial and commercial: mining operators, data centre operators, and other high-intensity energy users requiring reliable, low-emissions power at scale. The project is not oriented toward household electricity supply.
Three-stage development pathway to ~1 GW firm capacity
The grid-scale project is planned across three distinct stages:
- Stage 1 (2028/29): The initial 70 MW firm energy project that is the subject of the current EOI process, comprising the approved 140 MW BESS and 70 MW solar PV development.
- Stage 2 (2030/31): An expansion project incorporating additional BESS and PV capacity to support 200–500 MW of firmed power.
- Stage 3 (2031+): The ultimate 1 GW firm power platform, supported by a new 330 kV network link and Northern Water scheme infrastructure.
Across the full 1,580 ha precinct, the indicative development pathway points to approximately 2 GW of solar PV and approximately 1 GW of firm renewable capacity, with indicative full-development capital expenditure of approximately A$2 billion (approximately US$1.5 billion).
A key commercial incentive for prospective partners is that successful participants selected through this EOI process will also receive first rights to develop the broader 1,580 ha precinct beyond Stage One.
The process timeline, as disclosed in the announcement, runs as follows:
- January 2026: AEMO approval achieved
- Now: Expressions of Interest invited
- December 2026: Partner selection targeted to conclude
- Early 2027: Targeted financial close
- 2028/29: Stage One commercial operation targeted
Dr Kevin Moriarty, Executive Chairman
“With ownership secured and transmission line access well advanced, we are working to lock in power purchase agreements and attract investors to develop Aurora’s grid-scale. We recently appointed Shane Masters as CEO of SiliconAurora. Shane brings significant legal, finance and international private equity experience to this next phase and has a clear focus on achieving commercial results for our shareholders.”
Alongside the EOI launch, the Company confirmed the appointment of Shane Masters as Chief Executive Officer of SiliconAurora, bringing legal, finance and international private equity experience to the project’s next phase.
What this means for 1414 Degrees investors
The EOI launch represents a material step in 1414 Degrees’ stated strategy of combining near-term infrastructure revenue with scalable technology commercialisation. For existing shareholders, the significance lies not only in the project’s scale, but in what it signals about the Company’s commercial progress: moving from site acquisition to active partner solicitation with regulatory approvals already in hand.
The Company’s broader technology portfolio, spanning SiNTL™, SiBrick®, SiBox®, and SiPHyR®, sits alongside the Aurora infrastructure play as complementary platforms within a single silicon-based materials strategy. These are not yet central to the Aurora EOI itself, but they form the wider context for 1414 Degrees’ clean-energy and industrial decarbonisation platform.
Critically, the project carries meaningful de-risking at this stage. AEMO 5.3.4 / Generator Performance Standards approval was secured in 2026, meaning the Stage One development is not a greenfield concept awaiting regulatory clearance. Approvals are in hand ahead of the partner selection process.
The indicative process timeline targets partner selection to conclude by December 2026, financial close in early 2027, and Stage One commercial operation in 2028/29.
