  • Geothermal Power Generation in the World 2015-2020 Update Report
    Proceedings World Geothermal Congress 2020 Reykjavik, Iceland, April 26 – May 2, 2020 Geothermal Power Generation in the World 2015-2020 Update Report Gerald W. Huttrer Post Office Box 2425, Frisco, Colorado, USA [email protected] Keywords: World, geothermal, electricity generation, country update, development. ABSTRACT We have analyzed the major activities carried out for generation of geothermal electricity since WGC 2015. New data has been taken from the WGC 2020 Country Update reports, private communications from IGA members, and affiliated organizations. The author would like to acknowledge all of these data sources for their valuable help. Other updates have been collected from websites of private and public organizations involved in geothermal development as well as via personal communications. Plants under construction which are expected to be commissioned in 2020 are included in the installed capacity. An increase of about 3.649 GW has been achieved (about 27%) in the five year term 2015-2020. This figure deviates only slightly from the roughly linear increase trend documented since 2010. Five countries generated geothermal power for the first time. They are Belgium (0.8 MWe), Chile (48 MWe), Croatia (16.5 MWe), Honduras (35 MWe), and Hungary (3 MWe). 1. INTRODUCTION Though the author has written similar reports for WGS meetings in the past, it will be a difficult task to follow the path of Rugerro Bertani who has written so many excellent recent WGC Rapporteur reports and who sadly passed away too soon. In this, the WGC 2020 Rapporteur report, the major achievements of all nations having commissioned new geothermal power plants between 2015 and 2019 have been summarized.
