Ormat Technologies’ geothermal power plant in Amatitlán, Guatemala has been affected by ‘Agatha’, a recent tropical storm.

The 20MW plant’s gathering system has been damaged by the storm. The plant had only recently escaped without damage after the volcanic eruption of Volcan de Pacya that occurred a few days before the storm.

The plant had been temporarily shut down on 28 May 2010 to protect it from effects of the volcanic eruption.

Most of the wells will be connected to the plant and it will resume partial operation once the volcanic ash is cleared up, according to a company statement.

Ormat has not yet set a date for the plant to resume full operation.
