Hybrid Solar-Grid Power Strategy Drives Sustainability At Koné Gold Project In Côte d’Ivoire

Recent developments at the Koné gold project in Côte d’Ivoire highlight a broader shift in the mining sector toward integrating renewable energy into large-scale operations. Montage Gold, which is leading the project, has released an updated feasibility study outlining a hybrid power strategy that combines grid electricity with a dedicated solar photovoltaic (PV) plant.

Located in the northwest region of the country, the Koné mine is expected to become a major industrial project. To ensure a stable and cost-effective energy supply, the company plans to connect the site to the national electricity grid. This will be achieved through the construction of a 96-kilometer transmission line linking the mine to the Laboa substation. The grid connection will serve as the primary source of baseload power, supporting continuous operations such as mineral processing and heavy machinery use.

In addition to grid power, Montage Gold plans to install a 22 MWp solar PV plant at the site. This on-site renewable energy source will generate electricity during daylight hours, reducing reliance on grid supply and helping manage energy costs. Electricity expenses are typically a significant component of mining operations, and the hybrid approach is expected to optimize overall energy consumption while mitigating the impact of fluctuating tariffs.

The combined use of grid and solar power is designed to ensure reliable, round-the-clock operations while aligning with environmental, social, and governance (ESG) standards. The solar component, in particular, is expected to lower greenhouse gas emissions over the life of the project, supporting more sustainable mining practices.

Beyond energy planning, the project also incorporates measures for efficient water management and infrastructure development, addressing the challenges posed by seasonal variations in rainfall. These steps aim to enhance operational resilience in the region.

With a clear power strategy now in place, the Koné gold project is moving closer to a final investment decision. If implemented successfully, it could serve as a model for future mining projects in West Africa, demonstrating how industrial growth can be balanced with renewable energy adoption.
