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?

    a) foster an enabling environment to attract investments in geothermal energy;

    b) provide customised support to regions and countries with geothermal market potential;

    c) facilitate the exchange of insights and experience among key stakeholders in the geothermal energy value chain;

    d) identify and promote models for sharing and mitigating risks, in order to attract private investment and integrate geothermal facilities into energy markets.

    e) 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

Read more

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.

San Salvador, El Salvador

2nd High-Level Conference of the Global Geothermal Alliance - Geothermal, Driving the Energy Transition for Fostering Sustainable Development and Climate Action

The second high-level conference of the Global Geothermal Alliance (GGA) took place on 29 September – 1 October 2022 in San Salvador, El Salvador. The conference was attended by over 120 high-level representatives from governments, intergovernmental bodies, non-governmental institutions, and the private sector. The main outcome of the conference, the ‘San Salvador Declaration’, reaffirms the political commitment of member countries of the GGA to promote and scale up geothermal development worldwide. In the framework of the conference, IRENA organised organize two side events to promote Geothermal as an integral energy solution in SIDS and a capacity building on Powering agri-food value chains with geothermal heat with a focus on Latin America. Agenda, presentations, pictures, and video highlights of the conference are available here.

    Global Geothermal Market and Technology Assessment

    This global assessment provides an overview of developments in the geothermal sector and the factors that will shape the geothermal market in the near future.

    Over the last several decades, the geothermal industry has developed in different ways across the world. Different regions have distinct geographical and geological conditions, electricity and heat market conditions, policies and regulatory frameworks, development ambitions and implementation capacity. These factors have combined to produce different patterns in the development and use of geothermal resources.

    In the framework of the Global Geothermal Alliance (GGA), IRENA and the International Geothermal Association (IGA), developed the Global Geothermal Market and Technology Assessment report, to identify the factors driving geothermal development globally, and in different regions. The report provides an assessment of the status of geothermal electricity and heating and cooling capacities; as well as the key trends relating to technological advancement, cross-industry collaborations between geothermal and related sectors, and the increasing utilisation of low- and medium temperature resources for electricity generation, and heating and cooling applications. It also assesses the recent developments in the wider energy sector including energy transition and climate policies, the ongoing energy crisis, energy market policies, and their impact on geothermal development at the regional and global level.

    Finally, the report provides recommendations to guide policy makers, potential investors, development partners and other stakeholders on how to promote growth of geothermal markets, exploit the potential of geothermal energy and further expand geothermal’s integration within global energy systems.

    The development of the report benefited from the input of over 30 geothermal sector experts drawn from the constituency of the GGA.

    Powering Agri-food Value Chains with Geothermal Heat

    The proposed recommendations address challenges related to inadequate data on geothermal resources and existing heating demand for agri-food applications, absent or misaligned enabling framework conditions, inadequate financing, and lack of awareness. In addition, the guidebook recommends the adoption of methodologies to determine the tariff for geothermal heat as well as for quantifying the socio-economic impacts of deploying geothermal heat in the agri-food sector, as tools for supporting decision making.
