TORONTO (miningweekly.com) – Renewable power is reliable, proven and continues to offer the mining industry an attractive means to obtain lower-cost energy at remote operations, Hatch director of renewable power Michel Carreau told an audience at a seminar hosted by the Canadian German Chamber of Industry and Commerce’s Competence Centre for Mining and Mineral Resources on Friday.
The mining and renewable energy sectors must continue engaging with each other to develop joint solutions, he added. “This is a meeting of two worlds that, until quite recently, hadn’t worked together.”
Before a mining company selects a renewable component – whether wind, solar or another option – it must consider the economic viability and rate of return against the estimated mine life. The longer a mine is operational, the greater benefits renewables can deliver.
“Levels are typically fixed. For example, 15 cents per kW an hour would be a good bargain across 25 years,” Carreau said. “And while fuel costs are lower right now, remember this is just a moment in time; it will go up [in price].”
The level of power penetration by a renewable component varies; most provide mine sites with between 10% and 20% of their energy when in use. The goal of both the industries is to push this to a much higher level over the next five to ten years.
