Organisational structure Governance by a committee formed by members; membership open to all national governments, development partners, international and regional organisations, national, regional, and international industry associations, and academia. An Action Plan is developed by GGA members, in consultation with GGA partners, as laid down by the GGA Joint

Communique. GGA member countries and partners are not required to contribute a membership fee.

Description The Global Geothermal Alliance (GGA) is designed to ramp up the share of geothermal energy in the global energy mix both in the areas of geothermal power generation and the direct use of geothermal heat. The GGA serves as a platform for dialogue and knowledge-sharing among governments, international financing institutions, private sector investors and other practitioners as well as a coalition for action to increase the share of installed geothermal electricity and heat generation worldwide.
Objectives Key objectives of the Alliance are to:

- identify and promote models for sharing and reducing risks associated with the geothermal business to be able to attract timely and efficient private investments and to integrate geothermal facilities into energy markets. - help create enabling regulatory and institutional conditions for timely and efficient private investments and efficient operation of geothermal resources and associated network infrastructure. - help streamline ongoing outreach and awareness-raising efforts in order to give geothermal energy greater visibility in the energy and climate debates at global, regional and national level. The alliance goal is a five-fold growth in the installed capacity for geothermal power generation and at least two-fold growth for geothermal heating by 2030, compared to 2014 levels.

Activities Areas of support would include the creation of enabling regulatory and institutional conditions for investment; the promotion of innovative financing and risk mitigation mechanisms for geothermal drilling; the design of effective incentive schemes for geothermal power supply and direct use; and capacity building and technical assistance f.

Goals Long term objective:

Contribute to the realisation of geothermal energy potential to achieve a five-fold growth in the global installed capacity for geothermal power generation and two-fold growth for geothermal heating by 2030

The Action Plan adopted by all Member Countries in 2016 envisages four priority action areas.

1. Mapping of geothermal resources as well as identification of existing and potential geothermal markets and near terms projects in the pipeline.

2. Scoping of the needs for assistance to countries with transformative potential with a view to contributing to the removal of obstacles of policy, regulatory, funding or capacity building nature.

3. Supporting the development of effective enabling frameworks and associated mechanisms to achieve national objectives for geothermal energy deployment.

4. Establishing a robust global network of geothermal practitioners building upon existing networks. Additionally, the GGA aims to promote geothermal energy’s role in supporting decarbonisation strategies and the implementation of their Nationally Determined Contributions.

Comments on indicators and goals The CO2 reduction goal is taken from the report: "Individual actors, collective initiatives and their impact on global greenhouse gas emissions", New Climate, PBL, and Yale 2018.
How will goals be achieved

Progress towards the goals Since the launch of the initiative, efforts have focussed on the operationalization of the Alliance. To this end, through an intensive consultative process within the GGA constituency a concise plan of action for the Alliance (GGA Action Plan) was finalized and endorsed by the GGA Members in May 2016.

The later years prove that geothermal is a great option for decarbonising heating and cooling. The initial goal set in 2014 (more than two-fold growth) has already reached 52%. The installed capacity for heating applications went from 70GWt in 2015 is over 100GWt in 2020. For this reason, through an Energy Compact, that goal was updated to three-fold growth in geothermal heating and cooling in 2030 compared to the 2014 levels. This shows that the work of the GGA, its partners and members and other geothermal stakeholder has paid off in installed capacity growth and actual geothermal heat utilisation.

Following recommendations from leaders in the Florence Declaration, issued at the first High-Level Conference in 2017, the GGA began a focused work on direct use. In April 2018, IRENA co-organised the event “Geothermal Direct Utilisation and Food Security” with the Ministry for Foreign Affairs of Iceland and the Iceland Geothermal Cluster. During the meeting, key factors behind successful experiences were identified, lessons shared, and partnerships highlighted. Outcomes and case studies from the workshop were presented and discussed at the regional level. This process formed the basis of the IRENA publication entitled Accelerating geothermal heat adoption in the agri-food sector: Key lessons and recommendations, launched in January 2019. Follow-up capacity building for policy-makers and key stakeholders are under preparation.

Furthermore, through collaboration with key partners, the Alliance is promoting standardisation in the way resource assessments are classified and reported to promote a better understanding of the true potential and value of geothermal prospects. In this regard, a project with IRENA, International Geothermal Association and World Bank/ESMAP trained more than 100 local stakeholder and tested the application in pilot countries (Indonesia, Ethiopia, and a cluster of Eastern Caribbean islands) of the Specifications for the application of the United Nations Framework Classification for Fossil Energy and Mineral Reserves and Resources 2009 (UNFC-2009) to Geothermal Energy Resources. To this end, three technical sessions were held in Indonesia (Match 2018), St. Lucia (Dec 2018), and Ethiopia (Feb 2019).

How are you tracking progress of your initiative Monitoring of installed capacity for the power sector and generation for the heat sector.

Assessed the geothermal market conditions in East Africa, identified main barriers to deployment of geothermal technologies and made key recommendations to policy makers.
