About Us

Launched at COP21*, the Global Geothermal Alliance (GGA) serves as a platform for dialogue, cooperation and coordinated action between the geothermal industry, policy makers and stakeholders worldwide.

As stated in the Joint Communiqué on the Global Geothermal Alliance, the GGA is a coalition for action to increase the use of geothermal energy, both in power generation and direct use of heat. It calls on governments, business and other stakeholders to support the deployment of realizable geothermal potential. The Alliance has an aspirational goal to achieve a five-fold growth in the installed capacity for geothermal power generation and more than two-fold growth in geothermal heating by 2030.

What the GGA is designed to do?

  • foster an enabling environment to attract investments in geothermal energy;
  • provide customised support to regions and countries with geothermal market potential;
  • facilitate the exchange of insights and experience among key stakeholders in the geothermal energy value chain;
  • identify and promote models for sharing and mitigating risks, in order to attract private investment and integrate geothermal facilities into energy markets.
  • help to streamline outreach efforts to give geothermal energy greater visibility in the global energy and climate debates.

How To Join?

The GGA is an inclusive and neutral multi-stakeholder platform that brings together public, private, intergovernmental and non-governmental actors that share a common vision of accelerating the deployment of geothermal energy for power generation and other applications.

Member countries include geothermal resource-rich countries with established or emerging geothermal markets, along with other countries that wish to support the activities of the Alliance.

Partner institutions include:

  • Development partners, international and bilateral development organisations, international financial institutions, institutional investors, international organisations, and other development partners involved with geothermal energy.
  • Geothermal industry represented by geothermal business associations at the global, regional and national levels.
  • R&D and academic organisations operate in the geothermal energy field at regional, national or subnational levels.

Requests by interested countries and institutions should be sent to the International Renewable Energy Agency (IRENA), the coordinator and facilitator of the GGA, by way of an official written request addressed to IRENA’s Director-General.

Member countries and partner institutions are not required to contribute any membership fee. The costs associated with GGA activities, including coordination meetings, shall be borne by participants.

GGA Action Plan

The GGA Action Plan was endorsed by Members and Partners in May 2016, based on the principles stipulated in the GGA Joint Communique. It is set to coordinate closely with existing structures, programmes and facilities that share the common objective of promoting geothermal energy deployment at the international, regional and national levels. The Alliance will operate based on activities linked to the priority action areas identified in the GGA Action Plan, and will be supported in implementation as well as funding by committed Members and Partners.


The Global Atlas for Renewable Energy is a free online resource-assessment tool inclusive of maps on geothermal energy as well as solar, wind, marine and bioenergy resources. It facilitates a first screening of areas of geothermal investment opportunity

The BBA Geothermal Transparency Guide is an online tool which provides an insight into the legal frameworks governing exploration and development of geothermal energy, as well as an overview of data on energy production and capacity. Currently, 16 countries endowed with geothermal resources are featured in the database, with further countries to be included.


The Sustainable Energy Marketplace is a virtual platform that gathers project developers, financiers, service and technology suppliers to work together to realize projects related to geothermal and other renewable energy sources. The Marketplace provides a visibility to geothermal projects and facilitate investment opportunities

The International Geothermal Company and Expert Pool is a matchmaking platform to enable networking and recruitment opportunities for entities in need of consultants - and consultants/ company representatives looking for opportunities to become involved in geothermal projects.

IRENA Project Navigator is an online platform providing comprehensive, easily accessible, and practical information, tools and guidance to assist in the development of bankable renewable energy projects. In particular, the Project Navigator features a component dedicated to the geothermal power.

The Renewables Readiness Assessment (RRA) is a comprehensive tool for assessing the conditions existing in a country for the development and deployment of renewables, including geothermal energy, along with the actions required to improve those conditions. RRAs for the GGA Members: Djibouti, Fiji, Nicaragua, Peru, Phillipines, United Republic of Tanzania, Vanuatu, Zambia

REmap determines the realistic potential for countries, regions and the world to scale up renewables, including geothermal energy, in order to ensure an affordable and sustainable energy future. Reports for the GGA Members: India, Indonesia, Mexico, Poland, USA

Regional and International Training Centres

Geothermal Training Programme of the United Nations University

The Geothermal Training Programme of the United Nations University (UNU-GTP) is a postgraduate training programme, aiming to assist developing countries in capacity building within geothermal exploration and development.

The basic programme consists of a six-month annual training for practicing professionals from developing and transitional countries with significant geothermal potential. Priority is given to countries where geothermal development is under way, to maximise technology transfer. The sessions cover highly specialised studies in eight different lines, in geothermal geology, geophysical exploration, reservoir engineering and borehole geophysics, chemistry of thermal fluids, environmental science, geothermal utilization, drilling technology, and project management and finances.

The programme has operated in Iceland since 1979. It is a cooperation between the United Nations University and the Government of Iceland and is hosted by the Orkustofnun (National Energy Authority of Iceland).

The hallmark of UNU-GTP is to give university graduates engaged in geothermal work intensive on-the-job training in their chosen fields of specialization. The trainees work side by side with geothermal professionals in Iceland. The aim is to assist developing countries with significant geothermal potential in building up groups of specialists that cover most aspects of geothermal exploration and development. Thereby, enabling their capacity to develop and utilise their geothermal resources.

UNU-GTP also offers successful candidates the possibility of extending their studies to MSc, or PhD degrees in geothermal sciences or engineering in cooperation with the University of Iceland and Reykjavik University. Furthermore, annual short course series in support of the UN Sustainable Development Goals are given in East Africa (held in Kenya) and Latin America and the Caribbean (held in El Salvador).

Geothermal Diploma for Latin America in El Salvador

With its extensive geothermal history, CEL-LaGeo employs many experts working in the geothermal field. The vast technical, scientific and managerial capacities have been shared through various courses and workshops to young professionals from El Salvador, Latin America and the Caribbean in the framework of the Geothermal Training Programme of the United Nations University (UNU-GTP).

The 5-month Geothermal Diploma, with its seven editions, has contributed to make El Salvador a reference country as a centre of excellence for geothermal energy in the region. CEL-LaGeo and UNU-GTP signed a cooperation agreement to jointly implement a study programme carried out by Salvadoran and Icelandic experts during its latest two versions in 2016 and 2017. To date, a total of 689 professionals from Bolivia, Chile, Colombia, Costa Rica, Dominica, Ecuador, Guatemala, Honduras, Mexico, Montserrat, Nevis, Nicaragua, Peru, San Vincent and El Salvador have taken part in the geothermal short courses and the Geothermal Diploma imparted in El Salvador.
