In accordance with the commitments made last July, Rio Tinto QIT Madagascar Minerals (QMM) and its partner, CrossBoundary Energy (CBE), have laid the foundation stone for the solar and wind power plant project that will supply the QMM ilmenite mine operations in Fort Dauphin, southern Madagascar.

The ceremony took place in the Ehoala Park area, in the presence of high dignitaries, including the Minister of Energy and Hydrocarbons, the Minister of Environment, the mayor of Fort-Dauphin and the Governor of the Anosy Region. The renewable energy project will go some way to helping operations in Madagascar reach carbon neutral status by 2023.

The renewable energy plant will be built and operated by CBE, an independent power producer with whom QMM has signed a 20-year power purchase agreement. The first unit, an 8 MW solar energy facility, will be operational in 2022. The 12 MW wind power facility will be completed in 2023. The project also includes an 8.25 MW lithium-ion battery energy storage system.

Around 18,000 solar panels and four wind turbines will enable QMM to meet all of its electricity needs during peak periods and up to 60% of its annual electricity consumption, as well as to reduce its annual carbon dioxide emissions by about 26,000 t, Rio said. In addition, the renewable power supply will reduce QMM’s heavy fuel oil purchases by up to 8,500 t/y. With this plant, QMM will also replace the majority of the electricity it currently supplies to the town of Fort-Dauphin and its 80,000 community members with clean energy.

Ny Fanja Rakotomalala, President of QMM, said: “This project is a key component of our ‘sustainable mine’ initiative, which aims to leave a lasting legacy for present and future generations, built independently of our mining operations. We want to leave this legacy through permanent dialogue, the full integration of activities within the development plan of the region, responsible social and environmental governance, the reduction of our environmental footprint and therefore of our carbon footprint, and through the creation of economic and social opportunities increasingly independent of QMM.

“This project is a strategic test, not only in Madagascar but also in the mining industry as a whole, as we have to innovate and rethink our operations in order to combat climate change and leave a sustainable legacy.”

Matt Tilleard, Managing Partner of CBE, said: “By establishing a commercial power plant that blends solar photovoltaic, battery energy storage and wind power, the QMM project greatly improves the island of Madagascar standing as a regional renewable energy leader. CBE is pleased to take up this technical challenge. We believe large-scale, complex commercial energy projects can be realised here in Madagascar thanks to ample supply of renewable resources, holistic government support and knowledgeable local implementing partners.”

NextSource Materials has awarded a power supply contract to independent power producer CrossBoundary Energy (CBE) for the long-term supply of solar and thermal generation to power the operations of its Molo graphite project in Madagascar.

The contract is for a 20-year term and has been designed to scale with the production output of the Molo mine, where delivery of power will increase in lockstep with all future expansion capacity requirements, NextSource said.

A subsidiary of CBE in Madagascar is developing the project and will build, own and operate the Molo hybrid energy power plant at no capital cost to NextSource, it said. The plant will be located adjacent to the Molo mine site and is expected to be operational at the same time as the Molo mine is due to be commissioned in the June quarter of 2022.

“Through this contract, NextSource will initially be able to source up to one third of the Molo mine’s total electricity needs from renewable solar energy,” NextSource said. “NextSource and CBE are committed to optimising the solar component throughout the contract to increase the percentage of renewable energy to a majority.”

The hybrid energy power plant will comprise a 2.5 MW solar PV energy system, a 1 MWh battery energy storage system (BESS) and a 3.3 MW thermal energy system (diesel generators) that will supply all the electricity requirements for the Molo mine and processing plant. The thermal energy system will be used in combination with the solar plant and BESS to provide uninterrupted power supply and ensure 100% power availability to the mine, NextSource said.

The renewable energy services provided by CBE will be supplied exclusively to NextSource and provide guaranteed energy cost savings, according to the mine developer. This rate will lower expected energy costs on a per kWh basis versus the expected cost per kWh rate based on thermal power alone, as modelled in the company’s 2019 Molo feasibility study. This study outlined a phased development approach at Molo with Phase 1 producing 17,000 t/y over the first two years of production and Phase 2 producing a total of 45,000 t/y by year three. Earlier this year, the company announced the initiation of a technical study for an expanded Phase 2 production capacity of at least 150,000 t/y of SuperFlake® for Molo.

NextSource added: “The hybrid plant will contribute significantly towards NextSource’s adherence to its environmental, social and governance principles. It will also achieve the company’s broader initiative to reduce its environmental footprint through the deployment of renewable energy infrastructure to reduce emissions and work toward its goal of a carbon-neutral energy system.”

NextSource President and CEO, Craig Scherba, said: “Deployment of clean, renewable and sustainable power sources to reduce emissions is a cornerstone of our operational strategy and will reduce our expected energy costs over the life of our project.”

Matthew Fredericks, Head of Mining at CrossBoundary Energy, added: “We worked closely with the NextSource Materials team to design a custom solar hybrid solution for the Molo graphite facility. This power system will reduce the mine’s total cost of electricity, lowering its all-in sustaining costs, as well as minimising its carbon emissions. CBE is proud to be awarded this second project opportunity in Madagascar and honoured for NextSource Materials’ selection of our flexible, collaborative approach to sustainable energy solutions for African mines.”

Earlier this year, CBE announced two additional hybrid renewable energy projects, the first for Rio Tinto’s QMM ilmenite operation in Madagascar, and the second for Eramet’s mineral sands mine, Grande Cote Operations, in Senegal. In total, CBE is now delivering 40 MW of solar and wind generation and 20 MWh of battery energy storage capacity for African mines.

Rio Tinto has signed a power purchasing agreement for a new renewable energy plant to power the operations of its QMM ilmenite mine in Fort Dauphin, Southern Madagascar.

This project, which uses solar and wind energy, will significantly contribute towards Rio Tinto’s operations in Madagascar achieving its carbon neutral objective by 2023, it said. It is part of a broader initiative to reduce the ilmenite mine’s environmental footprint which includes programs that focus on emissions reduction, waste and water management, carbon sequestration, ecological restoration and reforestation.

QIT Madagascar Minerals (QMM), is a joint venture between Rio Tinto (80%) and the government of Madagascar (20%).

The renewable energy plant, to be built, owned and operated by independent power producer, CrossBoundary Energy, over a 20-year period, will consist of an 8 MW solar facility and a 12 MW wind energy facility to power mining and processing operations. There will also be a lithium-ion battery energy storage system of up to 8.25 MW as reserve capacity to ensure a stable and reliable network.

It will supply all of QMM’s electricity demand during peak generation times, and up to 60% of the operations’ annual electricity consumption, according to Rio. QMM is to replace the majority of the power it currently supplies to the town of Fort Dauphin and the community of around 80,000 people with renewables, the company added.

The renewable energy plant will comprise more than 18,000 solar panels and up to nine wind turbines located in the Port Ehoala Park area. Construction is expected to begin this year with the solar plant scheduled to start operations at the beginning 2022. The wind power plant is planned to commence construction in early 2022 and become operational by the end of 2022.

QMM President, Ny Fanja Rakotomalala, said: “On a sunny and windy day, all the electricity needed by QMM and the Fort Dauphin community will be generated by the Malagasy sun and wind. It is a major step forward on our journey towards a truly sustainable mine, that protects and promotes the uniqueness of Madagascar’s environment and benefits the community with reliable and clean electricity.”

Rio Tinto Minerals Chief Executive, Sinead Kaufman, said: “With this flagship project, QMM is leading the way at Rio Tinto and in Madagascar in utilising renewable energy to power mining operations and reduce carbon emissions.”

CrossBoundary Energy Co-founder and Managing Partner, Matt Tilleard, added: “Emissions from electricity use in mining is estimated to account for around 1% of all greenhouse gases globally. Rio Tinto is leading the way in demonstrating how mines can seize a huge opportunity to reduce these emissions. We are focused on delivering cleaner power to businesses and were, therefore, able to offer Rio Tinto a flexible, fast, all-equity funding approach, combined with our reliable track record as one of Africa’s largest distributed renewable utilities.”

QMM is near Fort Dauphin in the Anosy region of south-eastern Madagascar, and primarily produces ilmenite, in addition to zirsill and monazite. It includes the deep-water Port d’Ehoala, where the raw material is shipped to the Rio Tinto Fer et Titane plant in Canada and processed into titanium dioxide.
