Geothermal power is a highly reliable source of clean, renewable power. This is a feature that utilities such as CFE, looking to increase their share of renewables in the energy mix while maintaining secure supply, already find attractive. Despite the relatively high installation costs for a direct-cycle geothermal power plant such as Los Humeros in Mexico, the high capacity factor in operation results in a cost of electricity in the region of US$58 to US$93/MWh, even when taking into account the cost of drilling the wells and building the steam collection system.
