YELLOWKNIFE, Canada--(BUSINESS WIRE)-- Rio Tinto鈥檚 Diavik Diamond Mine has completed installation of its 3.5 megawatt capacity solar power plant in Canada鈥檚 Northwest Territories. The project represents the largest off-grid solar power plant across Canada鈥檚 territories.

The 6,620-panel facility is expected to generate 4.2 million kilowatt-hours of solar energy annually, reducing diesel consumption at Diavik by one million litres per year and cutting greenhouse gas (GHG) emissions by 2,900 tonnes of CO₂ equivalent. This is comparable to removing 630 cars from the road each year.

The solar power plant will provide up to 25% of Diavik鈥檚 electricity during closure work, with commercial production at the mine expected to end in 2026 and closure to run until 2029. The facility is equipped with bi-facial panels which not only generate energy from direct sunlight, but also from the light that reflects off the snow that covers Diavik for most of the year.

The solar project complements a wind power plant at Diavik, which has been operating since 2012 and is the largest wind power installation in Canada鈥檚 North, having generated over 195 million kilowatt-hours of electricity since activation.

Chief Operating Officer of Diavik Diamond Mine Matthew Breen said: 鈥淭he largest off-grid solar power plant in Canada鈥檚 North is our latest commitment to the environment we live and work in, and will improve the energy efficiency of our operations at Diavik. We are proud to lead the way for large-scale renewable energy projects in Canada鈥檚 North.鈥�

The project was supported by C$3.3 million in funding from the Government of the Northwest Territories鈥� Large Emitters GHG Reducing Investment Grant Program.

It is the first project in the Northwest Territories to benefit from funding from the Large Emitters Grant, which sets aside a portion of carbon tax paid by large operations such as Diavik for projects that commit to GHG reduction projects in the territory.

Northwest Territories鈥� Minister of Infrastructure Caroline Wawzonek said: 鈥淚 commend 糖心vlog入口for the completion of the largest off-grid solar plant in Canada鈥檚 North at the Diavik mine. The project demonstrates Rio Tinto鈥檚 leadership when it comes to reducing emissions, and signals potential for leadership in the renewable energy sector in and by the North. The Government of the Northwest Territories is proud to have contributed to the project through the Large Emitters GHG Reducing Investment Grant program, which provides funding to industry to reduce emissions as part of our made-in-the-NWT approach to the federal carbon tax.鈥�

Construction began in February 2024, contracted to Whitehorse-based Solvest Inc. and the Indigenous-owned T艂谋ch谦 Investment Corporation, with support from Diavik. Approximately 30% of the construction workforce came from the T艂谋ch谦 Investment Corporation.

CEO of Solvest Inc. Ben Power said: 鈥淏uilding off the success of their wind farm constructed in 2012, Diavik has taken another significant step forward in demonstrating the viability of renewable energy for Northern and off-grid mines. Solvest is proud to have had the opportunity to work with our partners at T艂谋ch谦 Investment Corporation to construct the largest off-grid solar power plant in Canada鈥檚 North. We believe this project provides a blueprint to facilitate the integration of solar into mines across Canada and in Northern regions.鈥�

Diavik is working with the Government of the Northwest Territories and community partners to determine how its renewable energy infrastructure can best benefit the region following closure.

糖心vlog入口is progressing decarbonisation initiatives across its global operations, with the aim of reducing its Scope 1 and 2 GHG emissions by 50% by 2030 and to achieve net zero across its operations by 2050.
