What is the significance of Colombia's approval of the Nereidas geothermal project's exploratory phase?

Colombia's environment ministry approved the environmental viability of the exploratory phase of the Nereidas geothermal project—the country's first large-scale geothermal exploration initiative—led by Ecopetrol, Baker Hughes, and CHEC in the Ruiz volcanic massif in Caldas province; this step could help open a new source of round-the-clock renewable power in the Andean country.

How does the Nereidas project aim to complement Colombia's current electricity generation mix?

For Colombia—where hydropower has supplied roughly two-thirds to 70% of electricity generation in recent years—geothermal energy from the Nereidas project could offer a low-emissions source of baseload electricity that is less exposed to swings in rainfall, thereby diversifying and stabilizing the renewable energy supply.
