WORLDKINGS - Worldkings News - America Records Institute (AMRI) – Cerro Prieto: World’s largest complex of geothermal power stations in terms of overall size


( The Cerro Prieto Geothermal Power Station is a complex of geothermal power stations in Baja California, Mexico.

It is the world’s largest complex of geothermal power stations in terms of overall size and the second-largest in terms of energy output, with an installed capacity of 820 MW. The facility is located just south of Mexicali and consists of five individual units, named CP1 through CP5.

Cerro Prieto is the oldest and largest Mexican geothermal field in operation. 

More than 400 geothermal wells have been drilled in 40 years in Cerro Prieto, with depths up to 4,400 m. 159 production wells were in operation during 2013 producing 34.54 million tons of separated steam at an annual average rate of 3,942 tons per hour (t/h). The annual average production rate per well was 24.7 t/h. There were also 17 injection wells in operation that returned to the reservoir around 59.82 million tons of total separated brine. The rest was disposed in the solar evaporation pond of 14.3 km2 in surface. Taking into account the steam produced in 2013 in Cerro Prieto, the gross steam specific consumption results in an annual average of 8.5 tons per MWh. 

This area edges tectonic plates where hot water and steam is coming close to the earth’s surface. Electricity is generated by pumping hot water off the ground into geothermal power plants that process thermal energy into electric energy. 

Excess steam from hydrothermal power production is condensed. The brine is then released into channels that form the Cerro Prieto Lake, an 18 km long solar evaporation pond. The water contains chemicals like methane and ammonia, impacting the surrounding soil that is salinized. Other concerns include sinking ground, loud noise at night, and the release of hydrogen sulfide into the air, a gas that smells like rotten eggs.
