SA Water has requested 1414 Degrees to have the GAS-TESS operational by the end of October to prepare for electricity export to the grid as an embedded generator on the National Electricity Market.

The Glenelg Wastewater Treatment Plant can generate electricity from gas engines, solar PV and the GAS-TESS but has not been able to export to the grid pending SA Power Networks’approval.

SA Power Networks intends to conduct verification testing and witnessing in November, and in preparation, SA Water requires all generation devices to be integrated into an upgraded plant control system, which will be implemented prior to SA Power Networks testing.

14D will commence recommissioning its GAS-TESS from Thursday,1 October, and will provide progress updates to the market as it proceeds.

1414 Degrees is pleased to provide an update on the Aurora Solar Energy Project, a transformative initiative aimed at delivering large-scale renewable energy solutions to South Australia. Located in the Upper Spencer Gulf region, the project is designed to integrate solar photovoltaic (PV) generation with advanced energy storage technologies, including battery energy storage systems (BESS) and the company’s proprietary Thermal Energy Storage System (TESS).

This hybrid model supports the transition to a low-carbon energy future by enabling reliable, dispatchable renewable power and industrial heat solutions.

The first stage of the Aurora Solar Energy Project includes a 70MW solar PV array paired with a 70MW/70MWh BESS. These assets will provide fast-response capabilities to support grid stability, frequency control, and energy arbitrage on the National Electricity Market (NEM). Engineering and regulatory development work is well underway, with connection approvals, site assessments, and early infrastructure design progressing steadily.

Looking ahead, the next stage will see the deployment of a TESS pilot system using the innovative SiBox® technology, a silicon-based thermal energy storage solution capable of delivering high-temperature, decarbonised industrial heat.

As outlined in the Aurora Solar Energy Project Development Update:

Historical modelling shows revenue potential

ITP Renewables modelled a hybrid solar power plant on the Aurora Project to maximise National Electricity Market (NEM) wholesale and ancillary services (FCAS) revenue. Their simulation of the past five years showed annual revenues ranging from $44m to $80m based on full share of FCAS market. Future revenue depends on capturing a proportion of this growth market, sales of energy on the NEM and through retailers. The regulatory market is adjusting and is expected to create further revenues for energy supply security.

Historical modelling confirms revenue potential for TESS + BESS

ITP Renewables modelled a TESS and BESS hybrid solar power plant on the Aurora Project to maximise National Electricity Market (NEM) wholesale and ancillary services (FCAS) revenue. Their simulation of the past five years showed that a combination of TESS and BESS storage increases potential revenue generation from the site through more flexibility of frequency response. Future revenue depends on capturing a proportion of this growth market, sales of energy on the NEM and through retailers. The regulatory market is adjusting and is expected to create further revenues for energy supply security.

These findings reinforce the commercial viability of Aurora’s integrated energy storage model and validate the company’s strategic direction.

• – Aurora could generate higher revenues by combining thermal (TESS) and battery (BESS) storage
• – Modelling shows TESS can earn substantial revenues from FCAS while charging from the grid

1414 Degrees (ASX:14D) is pleased to report first results from the modelling of a TESS-GRID in the context of the Aurora Solar Energy Project. A partial set of revenue stacks modelled by ITP Renewables (ITP) using historical data shows a positive revenue outlook for 14D’s TESS at the site. Charging the TESS from the grid can earn substantial revenues from FCAS services which in turn reduces the levelised cost of storage (LCOS). Importantly, the modelling shows that a combination of TESS and BESS storage increases potential revenue generation from the site through more flexibility of frequency response.

This extends encouraging modelling of revenues from a hybrid PV-BESS power plant on the site, as reported previously. ITP has been optimising and refining models of revenues from a variety of plant scenarios (see chart) incorporating TESS and BESS. 14D will commission specialist modelling using projections to 2050 for the Aurora business case and project financing.

1414 Degrees Executive Chairman, Dr Kevin Moriarty commented, “There are other revenue sources that cannot be predicted for inclusion in the stacks, and more are expected to be created as the regulatory market adjusts, driving down the LCOS to support TESS deployment in our proposed hybrid Silicon Power Plant at Aurora.”

He added, “A BESS and TESS can complement each other to provide short and long duration storage capabilities as described in AEMO’s recent Integrated System Plan. Our Aurora Solar Energy Project will demonstrate this to provide a model for the entire NEM.”

Notes on the modelling:

• – The TESS and BESS are charging from the grid in these scenarios
• – A TESS and BESS combination at existing solar and wind farms could maximise their revenue by making use of curtailed electricity for charging, and this would be an option as Aurora expands its PV generation
• – The model aims to maximise revenues by capturing the full potential of spot energy prices and FCAS in each time segment
• – TESS opens a significant opportunity in the FCAS market and, potentially, the AEMO demand response scheme, Reliability and Emergency Reserve Trader (RERT) because a TESS can charge and discharge independently, unlike batteries.

1414 Degrees is pleased to report progress on its Aurora Solar Energy Project (ASEP). 14D and Vast Solar have executed a Memorandum of Understanding (MOU) to investigate the commercial feasibility of incorporating Vast Solar’s modular Concentrated Solar Thermal Power (CSP) technology in a dispatchable renewable energy park.

Vast Solar has developed a modular CSP technology with assistance from the Australian Renewable Energy Agency (ARENA). Vast Solar is seeking sites to build larger plants to provide low cost, firmed electricity.

The proposed ASEP park will include 14D’s Thermal Energy Storage System (TESS) and other energy assets creating a globally important showcase of world-leading technologies to deliver dispatchable renewable electricity. The aim is to provide secure, reliable renewable electricity at low cost.

The collaboration will assess the mutual benefits of increased utilisation of the transmission assets, reduction of potential spilled energy and maximisation of revenue stacks to demonstrate competitive levelised cost of energy (LCOE) and levelised cost of storage (LCOS).

14D plans a multistage development of the Aurora Solar Energy Project with solar PV and batteries in the first stage of a hybrid power plant, followed by expansion to add 14D’s TESS and, potentially CSP.

• – 14D planning an efficient and cost-effective alternative power plant using SiBox technology
• – World-leading technology company supporting energy recovery system development

1414 Degrees (ASX:14D) is pleased to provide an update on the thermal energy efficiency of its SiBox thermal storage technology that will be used in the Silicon Power Plant proposed for its large Aurora Solar Energy Project in South Australia. It is engaging with multinational heat recovery specialist Nooter/Eriksen Inc (N/E) to maximise electricity generation from the SiBox.

SiBox, 14D’s scalable silicon based thermal energy storage (TES) for its Thermal Energy Storage System (TESS), is designed to operate at very high efficiency for long periods when cycled daily, thereby providing the equivalent functionality of thermal energy from burning fossil fuel at over 90% efficiency (Figure 1). Nooter/Eriksen’s involvement is to use SiBox energy to reliably supply steam generators and turbines, resulting in a heat-to-electric efficiency as in conventional fossil-fuel-fired steam turbines.

Figure 1: Key thermal power plant components for firmed, synchronous generation based on steam (gas alternatives not shown).

The key advantage of our new SiBox technology is that it will enable the economies of scale necessary to provide effective long-duration storage services at low cost. Scale is also important because the electrical efficiency of turbines increases with size. We are planning to increase the scale of our technology progressively, demonstrating the performance and reliability of the SiBox and its energy conversion system at each level (Figure 2).

Additionally, there is a growing need for dispatchable synchronous generation as more fossil fuel plants are retired and the penetration of variable renewable energy generators increases. 14D’s TESS is aimed at providing a complete clean thermal technology with synchronous output for the electricity network, unlike current plans to build more gas generation.

The decreasing cost of solar PV, projected to drop to around US$15/kW in coming years, makes SiBox competitive with fossil fuels as a source of synchronous electricity generation. This is an exciting development because the solar PV capacity of the Aurora Project can be increased as demand grows, allowing the Aurora project to expand incrementally and limit financial exposure. Hence, the benefits of the TESS technology as a value add service providing long-duration energy storage with synchronous output for grids and renewable energy farms can be progressively demonstrated at Aurora.
