The cooling towers of the Ahuachapán-3 power plant are part of a geothermal field that has been producing for more than a quarter century. The liquid-dominated geothermal reservoir has a base temperature of about 240 degrees centigrade. It is located on the northern flank of the Apaneca (Cuyanausul) Range along the southern margin of the Salvadoran central graben. Consequently it is lower to the north and NW, where it has been affected by graben subsidence.
