Abstract
The Miravalles geothermal field has been producing electric energy since March 1994. It has provided steam for Unit 1 (55 MWe) since 1994, a Wellhead Unit (5 MWe) installed in 1995, Unit 2 (55 MWe) in 1998, Unit 3 (29 MWe) in 2000, and also Unit 5 (19 MWe, a binary plant) in the year 2004. The steam production and fluid injection during these first 10 years of operation are described in the following sections, as well as the current and future improvements to the gathering system. Changes in strategies for production and injection are also discussed.
