Rio Tinto, a prominent mining company, has recently completed the construction of its solar power plant at the Diavik Diamond Mine in Canada’s Northwest Territories. This project marks a significant milestone as it represents the largest off-grid solar power plant across Canada’s territories. The completion of this 3.5-megawatt capacity solar power plant is a remarkable achievement that highlights Rio Tinto’s commitment to sustainability and environmental stewardship.

The Largest Off-Grid Solar Power Plant in Canada’s Territories

The solar power plant at the Diavik Diamond Mine comprises 6,620 solar panels and is expected to generate 4.2 million kilowatt-hours of solar energy annually. This substantial output will result in a significant reduction in diesel consumption at the mine, amounting to one million liters per year. Additionally, the solar plant will play a crucial role in cutting greenhouse gas emissions by 2,900 tonnes of CO2 equivalent. To put this into perspective, this reduction is equivalent to removing 630 cars from the road each year.

Sustainable Energy Solutions for the Future

One of the notable features of the Diavik Diamond Mine’s solar power plant is the use of bi-facial panels, which can generate energy not only from direct sunlight but also from the reflected light off the snow that covers the mine for a significant portion of the year. This innovative approach demonstrates Rio Tinto’s dedication to implementing sustainable energy solutions that are both efficient and environmentally friendly.

Collaborative Efforts and Community Involvement

The construction of the solar power plant was made possible through collaborations with Whitehorse-based Solvest Inc. and the Indigenous owned Tłı̨chǫ Investment Corporation. Approximately 30% of the construction workforce was sourced from the Tłı̨chǫ Investment Corporation, emphasizing the importance of community involvement and partnership in sustainable development initiatives. This project serves as a blueprint for integrating renewable energy solutions into mining operations and sets a new standard for environmentally conscious practices in the industry.

Driving Sustainable Practices and Environmental Leadership

Rio Tinto’s investment in the solar power plant at the Diavik Diamond Mine is a testament to the company’s commitment to reducing its environmental footprint and promoting sustainable practices. By leveraging renewable energy sources and embracing innovative technologies, Rio Tinto is leading the way in decarbonization initiatives across its global operations. The completion of this solar power plant aligns with Rio Tinto’s ambitious goals of reducing its GHG emissions by 50% by 2030 and achieving net zero emissions by 2050.


The successful construction of the solar power plant at the Diavik Diamond Mine underscores Rio Tinto’s dedication to environmental sustainability and renewable energy. By harnessing the power of solar energy, Rio Tinto is setting a new standard for responsible mining practices and demonstrating the positive impact of sustainable energy solutions. As the largest off-grid solar power plant in Canada’s territories, this project serves as a shining example of how collaboration, innovation, and environmental stewardship can drive meaningful change in the mining industry.
