GO15

What GO15 does

GO15 is a non-profit international association, founded in 2004 and headquartered in Lansdale, United States, that serves as the formal collaboration body for the world's Very Large Power Grid Operators. Its membership comprises 17 transmission and independent system operators across 17 countries — including ONS (Brazil), SGCC and CSG (China), RTE (France), IPTO (Greece), GCCIA (Gulf States), GRID-INDIA, Terna (Italy), TEPCO (Japan), SO UPS (Russia), National Grid SA (Saudi Arabia), Eskom/NTSCA (South Africa), KPX (South Korea), SwissGrid, and four US operators (CAISO, ERCOT, MISO, PJM Interconnection) — collectively serving more than half of global electricity demand. The association runs a small secretariat (1–10 employees) and is governed by a rotating Presidency and Vice Presidency drawn from member CEOs, with a Governing Board and Steering Board structure.

The association's core technology consists of collaborative technical research and knowledge-exchange outputs rather than software products. Its portfolio includes the biweekly World Power System Review publication, the Power Grids Outlooks compendium of member strategic documents, a recurring webinar series featuring external experts (Fraunhofer IEE, ENTSO-E), joint technical papers on storage, system stability and inertia, HVDC interconnection, resource adequacy, climate resilience, and CIM (Common Information Model) standardization, plus the annual GO15 Meeting. Recent workstreams surface member-led R&D such as Germany's €4M LISA national project on Dynamic Security Assessment for low-inertia systems. Distribution is via the go15.org website, a member portal, and in-person annual meetings hosted by member operators.

The business model is a traditional membership association: dues are paid by member operators and are not publicly disclosed, and the organization does not report revenue or pursue commercial monetization. There is no pricing model, no transactional revenue, and no investor base — GO15 is not structured as a commercial entity and has no equity holders. Its value proposition is functional: enabling knowledge exchange, joint studies, and best-practice sharing among the operators of the world's largest and most complex power grids, particularly as those grids navigate decarbonization, converter-based generation integration, and cross-border interconnection.

Core offering

GO15 is an international association of Very Large Power Grid Operators that facilitates technical collaboration, knowledge exchange, and joint research among 17 member transmission system operators from 17 countries. The association delivers its mission through regular publications (World Power System Review, Power Grids Outlooks), collaborative technical papers, webinars featuring members and external experts, and an annual meeting hosted on a rotating basis by member operators.

Product overview

GO15 is an international association of very large power grid operators, offering a portfolio of knowledge-sharing products including the World Power System Review (regular publications), Power Grids Outlooks (member strategic documents), Webinars (online presentations on grid operations topics), and Technical Papers (collaborative studies on system challenges). The association also organizes an Annual Meeting for member collaboration. These products collectively support information exchange and best practice sharing among the world's largest transmission system operators.

Direct peers

• EPRI (Electric Power Research Institute): EPRI is a nonprofit research consortium that conducts collaborative R&D for the electricity sector. Like GO15, it produces technical reports, frameworks, and member-driven studies addressing transmission planning, resource adequacy, and grid modernization — directly relevant to GO15's member operators.
• NERC (North American Electric Reliability Corporation):
• IEEE Power & Energy Society (IEEE PES): IEEE PES is a professional society focused on power and energy engineering, listed by GO15 as a useful partner. Both serve as global technical communities for power-system professionals, publish standards and reference materials, and host conferences/webinars on grid-operation topics.
• CIGRE (International Council on Large Electric Systems): CIGRE is a global nonprofit organization for power system expertise, publishing technical studies and convening working groups on grid challenges. It overlaps with GO15 in audience (transmission system engineers and operators), topical coverage (stability, HVDC, interconnection), and output format (technical papers, study committees).
• ENTSO-E (European Network of Transmission System Operators for Electricity): ENTSO-E is the European association of TSOs and GO15's closest comparable organization. Both serve as multilateral platforms for large grid operators to collaborate on technical studies, policy positions, and energy-transition initiatives; GO15 itself lists ENTSO-E as a strategic partner and they jointly sign declarations (e.g., COP26 commitments).
• Med-TSO (Mediterranean Transmission System Operators): Med-TSO is a regional TSO association covering Mediterranean countries. It operates on a similar membership-association model as GO15, focused on technical cooperation among grid operators, and has signed joint declarations with GO15 and ENTSO-E ahead of COP26.
