Abstract
The Miravalles Geothermal Field has been producing electric energy since March 1994. It has provided steam for Unit 1 (55 MWe, installed 1994), a wellhead unit (5 MWe, 1995), Unit 2 (55 MWe, 1998) and Unit 3 (29 MWe, 2000). A 19 MWe "bottoming cycle" plant (Unit 5) that was completed in January 2004 has brought the total installed capacity in Miravelles to 163 MWe. The performance of the field in terms of the behavior of reservoir pressure due to exploitation is described in the following sections. The field has successfully supplied the steam needed to generate the installed capacity over the first ten years of exploitation.
