International Geothermal Association

What International Geothermal Association does

The International Geothermal Association (IGA) is a non-profit international organization founded in 1988 and headquartered in The Hague, Netherlands, with operational contact in Bochum, Germany. Its stated mission is to promote the development and deployment of geothermal energy worldwide, and it functions as the de facto global coordinating body for the sector, with 60 corporate members, 30 affiliated organizations, 10,000+ geothermal professionals, and a presence in 88 countries. IGA holds consultative status with UN ECOSOC and maintains working relationships with the World Bank, IRENA, IEA, and the Green Climate Fund.

IGA's core product surface comprises the IGA Academy (education and training), the Geothermal Energy Database, the Conference Paper Database, the Geothermal Supply Chain and Procurement (GSAP) platform, the GLOBAL_GT advocacy campaign, and the World Geothermal Congress (WGC) — the sector's flagship international event. Its technology stack is lightweight and operations-oriented: ActiveCampaign for email, Stripe for payment processing, and Matomo for web analytics. There is no disclosed AI/ML capability and no proprietary software product beyond the data and community platforms.

Revenue is generated primarily through tiered membership dues (Gold/Silver/Bronze corporate tiers, plus institutional, individual, and student categories) and event participation fees tied to WGC and related gatherings. The organization is operated by a 3-person executive team — CEO Marit Brommer, R&D Manager Helen Robinson, and Events & Partnerships Manager Gregor Rumberg — supported by a 7-member board, implying a lean cost structure consistent with a small association budget.

Scale indicators5 records

Recent moves6 records

Expansion highlights5 records

Regional players

• European Geothermal Energy Council (EGEC): European-focused geothermal industry association representing the sector to EU institutions. Comparable peer as a geothermal advocacy body, but with regional rather than global scope, making it both a peer and a potential collaborator.

Broad incumbents

• REN21 (Renewable Energy Policy Network for the 21st Century): Global multi-stakeholder network tracking renewable energy policy including geothermal. Comparable policy-advocacy and intelligence-gathering function but operating across all renewables rather than geothermal specifically.
• International Renewable Energy Agency (IRENA): Intergovernmental organization supporting all renewable energy technologies, including geothermal. Comparable as a global renewable energy advocacy platform with policy influence, but broader in scope than IGA's geothermal focus.
• World Energy Council: Global membership-based energy organization covering the full energy spectrum. Comparable as an international energy membership association with events (World Energy Congress) and policy advocacy, though broader than geothermal focus.

Direct peers

• International Hydropower Association (IHA): International membership-based association for the hydropower sector. Highly comparable as a renewable-energy-specific international trade association providing advocacy, training, and events for a single technology vertical.
• Global Wind Organisation (GWO): International standards-based organization serving the wind energy sector with training, safety standards, and member services. Directly comparable as a renewable-energy international body providing frameworks and capacity building.
• International Solar Alliance (ISA): International intergovernmental organization promoting solar energy adoption with member-driven governance and policy advocacy. Highly comparable as a single-renewable-technology international body with similar membership and policy structures.
• World Bioenergy Association (WBA): International non-profit promoting bioenergy with advocacy, policy work, and global events. Directly comparable membership-association model focused on a single renewable energy vertical.
• Geothermal Resources Council (GRC): US-focused geothermal industry association providing conferences (Annual Meeting), publications (Geothermal Resources Council Transactions), and member services. Directly comparable as a geothermal-specific association, though more regionally focused.

Others

• Clean Cooling Network / Global Cooling Institute: Industry networks focused on district cooling and refrigeration with advocacy and member services. Less directly comparable but adjacent in the renewable thermal/utilization space that overlaps with geothermal direct-use applications.
