The demographic impact of the Cerro Prieto Geothermal Power Station is relatively limited, as the power station is located in a sparsely populated area. However, the plant has had a significant economic impact on the region, providing employment opportunities and contributing to the local economy through the purchase of goods and services.
Development of the Cerro Prieto Geothermal Power Station
The development of the Cerro Prieto Geothermal Power Station began in the late 1960s, when the Mexican government began exploring the potential of geothermal energy as a source of electricity. The site for the power plant was selected due to its location above a large geothermal reservoir, which was discovered during drilling operations for oil and gas.
Construction of the plant began in 1970, with the first stage of the project involving the drilling of production and injection wells to access the geothermal reservoir. This was followed by the construction of the power plant itself, which included the installation of turbines, generators, and other equipment necessary for electricity production. The first stage of the plant, which had a capacity of 180 MW, was completed in 1973.
A second stage of development was undertaken in the early 1980s, with the construction of additional generating units and other infrastructure to expand the plant's capacity to 720 MW. This involved the drilling of additional production and injection wells, as well as the construction of new transmission lines and substations to connect the plant to the national grid
Throughout the construction process, the Mexican government worked closely with international partners and private companies to finance and manage the project. This included partnerships with the United Nations Development Programme, the World Bank, and other international organizations, as well as collaborations with private companies such as Mitsubishi and Sumitomo.
Today, the Cerro Prieto Geothermal Power Station remains one of the largest geothermal power plants in the world, and continues to be operated by the Mexican Federal Electricity Commission (CFE) to meet the growing demand for electricity in the region. The plant has helped to establish Mexico as a leader in the development of geothermal energy resources, and has contributed significantly to the country's energy security and economic development.
