Red 5 taps Zenith Energy for hybrid power options at King of the Hills gold project

Red 5 Ltd has entered into a Power Purchase Agreement with a subsidiary of Zenith Energy Ltd that will see the growing Australia-based power producer build, own and operate approximately 30 MW of hybrid power generation capacity to service the needs of the King of the Hills (KOTH) project in Western Australia.

The power inputs as part of the BOO agreement comprise high efficiency reciprocating gas fuel power generation together with a 2 MW photovoltaic solar farm (an example from Zenith’s other work shown above) and a battery energy storage system.

Power supply to the site is planned to commence in the March quarter of 2022 with an initial term of 10 years. The contract includes provision for a potential future upgrade to the power station to support increased plant throughput beyond the initial planned 4 Mt/y run rate, Red 5 says.

Gas will be supplied from the Goldfields Gas Pipeline, 12 km west of the mine, under separate contracts, the company clarified.

Red 5 Managing Director, Mark Williams, said the award of the agreement marked another important construction milestone for the King of the Hills project while, at the same time, helping to achieve one of the company’s environmental, social and governance commitments to reduce the carbon footprint of the project.

“We are pleased to have signed the Power Purchase Agreement with Zenith, an experienced power producer which provided us with a compelling hybrid thermal and sustainable power solution that includes renewable energy,” he said. “Zenith’s combination of a gas and solar power station, supported by a battery energy storage system, provides the efficiency and stability required for the processing plant and infrastructure to enable King of the Hills to be a long-life, low-cost gold producer.”

The KOTH project is an open pit and underground gold deposit with a projected mine life of over 16 years. This could see the company produce 176,000 oz/y of gold over the first six years, according to a recent feasibility study.

Aggreko to energise mine power space with investment proposition

Mobile power provider Aggreko says it is making the transition from being a pure power provider to a long-term mining project investor that is helping miners navigate the energy transition.

Aggreko has built an almost 60-year-long reputation for powering many sectors around the globe. It has also supplied power and underground cooling to the mining sector for more than 35 years and has evolved into life-of-mine contracts and renewables.

In its latest report – which details its future energy transition – Aggreko cites mining as a major growth sector. Aggreko Australia Pacific Managing Director, George Whyte, stated that Aggreko’s global team’s unique offering is with build-own-operate investments across all continents.

As well as continuing to invest upward of £250 million ($347 million) annually in technology and innovation, the company says it is ready to further boost its investments in the natural resources industry.

Whyte said: “Investor partnerships can support the rapid changes in technology and emissions compliance that our mining customers are facing. Investing millions of dollars in capital for a mine’s power plant is a risk for any company, and, as a partner, Aggreko takes on this risk instead of the mining company. It is a smart way for miners to do business in the post-COVID and renewables era.”

Aggreko’s Global Head of Mining, Rod Saffy, said miners struggling to get funding for capital expenditure projects were looking to outsource, and there was a trend toward creating partnerships with providers.

“Partnerships provide more value beyond de-risking project finances,” Saffy said. “There are technology and emissions risks, so by partnering with us, for example, we aren’t just supplying equipment and labour, we share in decision making and project milestones, we invest and update technology on-site and navigate social and environmental impacts together.”
Saffy said companies looking to build power stations for the first time particularly benefited from supportive partnerships with Aggreko.

“Power stations are our core business, and they have become much more complex on mine sites than they have been in the past,” he said. “It is challenging to get funding to build power stations, and miners are needing support to integrate renewables into their plans immediately or in the future, or needing solutions designed from scratch.

“Partnering with us is a sustainable and beneficial business solution. Miners are wanting hybrid power stations that might utilise a mix of energy sources such as diesel, gas, solar or battery, for example. They also want that power to be scaled up or down and upgraded as their needs change and new technology comes online.”

Saffy said mines throughout the world were becoming less dependent on mass-scale thermal plants to deliver baseload power through national grids.

“With the cost of renewable power generation falling, there is also growth in localised microgrids, which means less dependence or complete independence from the grid,” he said. “Miners in Australia, Africa and South America, where there is less infrastructure in remote locations, are finding it particularly helpful to partner with us from the start of a major project.”

One such example is the Gold Fields Salares Norte Mine in northern Chile where Aggreko has become a major investor, and partner for the mining project for at least 10 years. The mine is located 190 km from the nearest town and is 4,500 m above sea level, and Aggreko is creating an off-grid hybrid power solution, comprising of diesel and solar for the harsh environmental conditions. Aggreko estimates the mine will experience $7.4 million in cost energy savings across the 10 years.

Saffy said the benefits for Aggreko in partnering and investing with miners from the beginning of their project to the end of the life of mine was beneficial for both parties.

“As a partner, Aggreko de-risks the threat of future innovation and technology for miners,” he said. “Our build, own, operate and maintain model frees up working capital without increasing the debt ratio for mining projects. Modular equipment also gives miners the ability to leverage innovation at low risk and not be concerned about having the latest equipment.

“We benefit too, by showcasing our expertise and innovations throughout a project’s lifecycle and support mining companies to reduce emissions and increase their operational efficiencies.”

Late last year, Aggreko committed to achieving net zero emissions by 2050.

Galena signs up Contract Power for hybrid power gen facility at Abra JV

Abra Mining Pty Ltd, the joint venture company behind the Abra base metals project, has executed a power purchase agreement (PPA) with Contract Power Australia that could see the construction and operation of a hybrid power generation facility made up of a natural gas and solar energy array at the Western Australia project.

Announcing the PPA, Galena Mining, which owns 77.28% of the project, said Contract Power will build, own and operate an integrated hybrid power generation facility combining a 10 MW natural gas fired power station, a 6 MW solar array, 2 MW of battery energy storage and a 900 Kl LNG storage and regasification facility.

Power will be purchased by Abra under the PPA for an initial term of 16-years (extendable), it said.

Galena Managing Director, Alex Molyneux, said: “We’re pleased to partner with Contract Power on a clean, cost-effective power solution for Abra. Integrating solar with relatively clean natural gas instead of diesel achieves a marked reduction in Abra’s carbon footprint compared to alternatives considered in the tender process.

“Pleasingly, the design also offered the most cost-effective solution, in line with our feasibility study estimates.”

This definitive feasibility study outlined development of a mine and processing facility with a 16-year life producing a high-value, high-grade lead-silver concentrate containing around 95,000 t/y of lead and 805,000 oz/y of silver after ramp-up.

A Western Australia-based company wholly-owned by Pacific Energy Ltd, Contract Power specialises in the design, construction and operation of remote power stations for the mining and government sectors.

Contract Power has operated power stations around Australia under turnkey build-own-operate arrangements since 1999, and recent projects include a 56 MW gas fired power station for Mineral Resources Ltd’s Wodgina lithium project, a 18 MW gas fired station for Capricorn Resources’ Karlawinda project and a 18 MW gas and diesel power station at Wiluna Mining Corp‘s Wiluna gold project.

Contract Power’s Managing Director, Leon Hodges, said: “We are very pleased to be working with Galena on this important project and look forward to rewarding their confidence by delivering a world-class hybrid power station.

“Contract Power’s combined LNG and renewables integration capability has allowed our design team to maximise solar penetration as high as the economics and technology allows, providing the Abra project with the highest reliability and lowest cost of power on an unsubsidised basis.”

The PPA remains subject to the condition of Abra Mining Pty Ltd proceeding to final investment decision for the project, Galena said.

Strandline energises Coburn mineral sands plan with Contract Power BOO agreement

Strandline Resources says it has taken another important step towards development of its Coburn mineral sands project in Western Australia by appointing Contract Power Australia as preferred contractor to build, own and operate (BOO) the power generation facilities for the project.

Coburn’s purpose-designed power infrastructure is based on a low-cost, low-emission solution integrating natural gas fuelled generation with solar and battery storage technology.

The proposed power solution enables Strandline to capture energy supply cost savings relative to the definitive feasibility study published in June 2020, it said.

Contract Power, a wholly-owned subsidiary of Pacific Energy Ltd, specialises in turnkey design, installation and operation of energy assets and has a strong track record of delivery in the mining sector of Western Australia, Strandline says.

Coburn’s power station will be located near the mineral separation plant. The power station is designed for a maximum demand capacity of 16 MW and average consumed power of circa-10 MW. Natural gas will be supplied by others under an industry standard long-term LNG supply agreement and trucked to an on-site storage and re-vapourisation facility supplied by Contract Power (Contract Power’s typical LNG-fuelled power station build layout, pictured), according to Strandline. The LNG then feeds a set of engine generators on an N+1 basis and has circa-30% solar penetration for the major stable loads. Generation is at 11 kV with step up to 22 kV for power transmission to the project loads across the mine site, Strandline says.

As preferred contractor, the parties will now compile final contract documentation to the satisfaction of Strandline and Coburn’s lenders. The contract is based on a 15-year BOO (and maintain) commercial model with fixed and variable payment regime for power consumed over the term.

This appointment follows Strandline’s recent A$18.5 million ($13.1 million) equity raising to advance early works development activities while finalising the balance of project funding. Strandline says it continues to make strong progress towards definitive finance documentation and conditions precedent for the NAIF A$150 million loan facility and is advancing discussions to secure a commercial debt tranche expected to stand alongside the NAIF funding.

Since raising the A$18.5 million, Strandline has appointed Macmahon as the principal contractor to provide site-wide civil and bulk earthworks construction services for the project, instructed Piacentini & Son to design and construct three mobile dozer mining units for Coburn and awarded preferred EPC status to Primero Group for the mineral sands asset.

Strandline Managing Director, Luke Graham, said the appointment marked another key step in its strategy to bring Coburn into production and establishes an important relationship with Contract Power, a leader in sustainable clean energy generation in Western Australia.

Coburn has a JORC compliant mineral resource of 1,600 Mt at 1.2% total heavy mineral (THM), classified as 119 Mt measured, 607 Mt indicated, and 880 Mt inferred. The ore reserve comes in at 523 Mt grading 1.11% THM for circa-5.8 Mt of contained heavy mineral, underpinning an initial mine life of 22.5 years at a mining rate of 23.4 Mt/y.

Northvolt and Vattenfall partner on modular zero-emission power option offering

Northvolt and Vattenfall have announced a new battery energy storage solution that could provide a zero-emission alternative to running diesel generators on remote mine sites.

The Voltpack Mobile System is a rugged, highly modular lithium-ion battery system that can serve as a modular power supply solution to meet energy and power requirements of a wide variety of market scenarios, the companies said.

Prime applications include powering remote electricity grids, reinforcing weak grids, supporting electric vehicle charging and delivering grid services such as balancing power, flexibility, or other ancillary services, they said.

“Designed for redeployment, the system can be deployed for operations lasting days, weeks or even longer periods of time,” the companies said. “This characteristic opens Voltpack Mobile System up to opportunities of leasing and is expected to significantly expand the system’s utility.”

Within the project, Northvolt has led development and production of core technologies, including battery and complementary inverter systems, and the battery management system. Vattenfall, drawing on the company’s experience of delivering commercial grid solutions to market, has supported Voltpack Mobile System project development to tailor the product to match the needs of the market, through both advising on design and functionality, they said.

Emad Zand, President Battery Systems, Northvolt, said the company sees an increased need from the market for flexible solutions, both in terms of use case and location.

“Voltpack Mobile System is designed to give our customers a fleet of assets that can be redeployed, repurposed and connected seamlessly,” he said. “Vattenfall has been an invaluable partner of Northvolt since our earliest days, and their contributions to this project have enabled us to accelerate development of a product built to customer requirements.”

Torbjörn Johansson, Head of Vattenfall Network Solutions Sweden, said: “The need for flexible energy solutions such as energy storage is vital for the transition to the new energy system. Energy storage provides fast access to power when customers need to peak-shave, or the capacity of the grid connection is insufficient.

“The battery storage solution will be offered as part of our concept ‘Power-as-a-service’, which means that we deliver a complete package with ownership of the energy storage and manage it to the specification of the customer. Vattenfall add(s) a long experience of owning and operating different kind of network solutions including energy storage.”

Final validation of the system will be undertaken at Vattenfall’s test and certification centre in Älvkarleby, Sweden.

Vattenfall will be the first to offer the battery unit to the market and has identified the need for sustainable solutions at industries, for microgrids, construction sites as well as for event organisers, the companies said.

Voltpack Mobile System delivers up to 250 kW with a scalable capacity from 245 kWh to 1,225 kWh of available energy, according to the companies.

“The system scales through a central interface hub, which can connect in parallel up to five self-contained Voltpacks, each containing three liquid-cooled, industrial-grade battery Voltpack Cores,” the companies said. “The hub also serves as an interface for applications, and houses inverter and auxiliary systems. If further power or storage capacity is needed, this can be fulfilled simply by connecting multiple Voltpack Mobile Systems in parallel.”

Voltpacks feature high safety standards and are designed and built by Northvolt, the companies said.

“Leveraging field-proven technologies, Voltpack Mobile System is well-suited to operate under even the harshest conditions with a rugged profile and unique design features engineered for transportation and repeated redeployment.”

EDL brings 56 MW hybrid renewable energy project online at Gold Fields’ Agnew mine

Global energy producer EDL says it has successfully completed the 56 MW Agnew Hybrid Renewable project for Gold Fields’ Agnew gold mine in Western Australia.

All five wind turbines are now up and running and successfully integrated into Australia’s largest hybrid renewable microgrid, and the first in the country to power a mine with wind-generated electricity, it said.

In favourable weather conditions, the project has delivered up to 70% of Agnew’s power requirements with renewable energy, according to the company. This is significant as the Agnew mine consists of two underground complexes and one 1.3 Mt/y processing plant consisting of a three-stage crushing circuit, two-stage milling circuit, gravity circuit and carbon-in-pulp circuit.

Upon announcing the project in June 2019, Gold Fields and EDL said the A$112 million ($78 million) investment would help create a “world-leading energy microgrid combining wind, solar, gas and battery storage”.

The project comprises four key components controlled by an advanced microgrid system. This includes five 110 m wind turbines, each with a rotor diameter of 140 m, delivering 18 MW; a 10,710-panel solar farm generating 4 MW; a 13 MW/4 MWh battery system; and an off-grid 21 MW gas/diesel engine power plant.

The Australian Renewable Energy Agency (ARENA) provided A$13.5 million ($8.7 million) in funding to the project as part of its Advancing Renewables Program.

EDL Chief Executive Officer, James Harman, said: “We applaud Gold Fields for their vision in embarking on this journey with us, and their role in leading the Australian mining industry’s transition to clean, reliable renewable energy.

“We also acknowledge the incredible achievement of the EDL project delivery team and our contractors. We faced transport challenges during the bushfires and impacts on personnel from COVID-19 restrictions, as well as geographical, logistics and technical challenges to safely construct this innovative energy facility in the remote WA Goldfields region.”

Gold Fields Executive Vice President Australasia, Stuart Mathews, said the completion of the project was an important milestone for Gold Fields, EDL and the broader mining industry.

“We are proud to be able to showcase this project with EDL as an outstanding example of the capacity of the hybrid renewable energy model to meet the dynamic power requirements of remote mining operations.

“For our people and our stakeholders, this is a very clear demonstration of our commitment to reducing our carbon footprint whilst strengthening our security of supply.

“Having built our internal technical capability and developed strong relationships with our business partners, we are well placed to continue to implement renewables solutions elsewhere in our business.”
