Allied Gold gets a renewable upgrade

From the newsletter

Canadian miner Allied Gold is overhauling its energy system at the Sadiola gold mine in Mali, transitioning from diesel to a hybrid system that combines solar with batteries. This shift aims to reduce power costs, minimise outages, and facilitate expansion. It reflects a broader trend in mining where renewable power is now critical to margins and operational resilience.

• Diesel generation in off-grid mines can cost 3 times more per kilowatt-hour than solar plus storage. For a mine like Sadiola, where energy is 25% of operating costs, hybrid systems offer a direct margin advantage.

• Mining companies are increasingly turning to renewables amid rising costs and sustainability pressures. Companies like Kamoa Copper in the DRC are developing a 222 MW solar system with a 526 MWh battery system for baseload power.
