Chilean state oil company Enap is developing four geothermal plants in alliance with private companies that will begin to come online in 2011, according to a presentation given in Valparaíso by Enap general manager Enrique Dávila.
The Apacheta 1 geothermal plant in Chile region III outside the northern city of Calama will begin adding 40MW of capacity to the northern SING grid in 2011. Exploration costs will reach US$23mn and development costs will exceed US$110mn.
The Apacheta area could see geothermal capacity rise to 150MW, according to the presentation.
Also in the north, the Tatio I plant is expected to come online in 2011, adding 40MW capacity to the SING. Exploration costs are expected to reach US$27mn and development costs will hit US$126mn.
The El Tatio-La Torta area near San Pedro de Atacama could eventually provide up to 480MW of geothermal capacity.
In southern Chile, two plants will begin to come online in 2012.
The Chillán 1 plant near the city of the same name will add 25MW capacity to Chile's central SIC grid and start operations in 2012. Exploration costs will reach US$23mn and development costs will hit US$100mn. The Chillán geothermal area could eventually add 80MW of capacity.
The Calabozo 1 plant, meanwhile, near the southern city of Talca will begin operations in 2013 and add 40MW of capacity to the SIC. Exploration costs were stated at US$31mn and development costs will reach US$130mn. The Calabozo area could see its geothermal capacity increased to 380MW, according to the presentation.
