Geothermal Energy in Mexico

Geothermal Fields and Zones in Mexico

Geothermal resources in Mexico are used mostly to produce electrical energy. Direct uses of geothermal are practically restricted to bathing and swimming pools. Up to present (2000), the geothermal electric capacity is 755 megawatts (MW), which is installed in the Mexican geothermal fields of Cerro Prieto (620 MW), Los Azufres (93 MW) and Los Humeros (42 MW). The reconnaissance and inventory of thermal areas in Mexico was finished in 1987. As a result, 545 thermal localities were identified, grouping around 1,380 hot spots, including springs, shallow wells, fumaroles, steaming grounds, etc.

The annual geothermal production in Mexico (1999) is around 56 million metric tons of steam, at an annual average rate of 6,400 tons per hour. This amount of steam is produced by an average of 164 geothermal wells, whose depths vary from 600 to 3,500 meters. Humeros field.

They generated 5,619 gigawatts-hour (GWh) in 1999, with an annual average capacity factor of 86% and a specific consumption of 10 tons per megawatt-hour. Geothermal electricity generation represented 3.2% of the total electric energy produced in Mexico in 1999.
