Allied Gold Unveils Major Solar and Battery Storage Initiative to Power Sadiola Mine Expansion in Mali

Canadian miner Allied Gold Corporation has initiated a multi-phase energy strategy to support the expansion of its Sadiola gold mine in Mali, aiming to replace diesel generation, integrate solar and storage systems, and slash power costs.

Under the program, the company plans to decommission existing diesel generators and install a 14 MW diesel power plant with advanced control systems by early 2026 to boost operational efficiency. By mid-2027, a 35 MW solar PV installation paired with 30 MWh of battery storage is slated for integration into the power mix. Further upgrades through 2028 include medium-speed thermal generators and a scaling up of renewables capacity to 60 MW solar plus 45 MWh storage, targeting an overall energy cost reduction of up to 45 percent.

Allied Gold projects that Sadiola’s energy demand will average 20 MW during Phase 1 of expansion, rising to 32 MW in Phase 2 as mining operations scale. The shift toward hybrid energy infrastructure is expected to reduce diesel dependency and enhance the mine’s sustainability profile.

This move aligns with Allied Gold’s broader strategy of optimizing power systems across its operations in West Africa amid rising generation costs and environmental considerations.
