North Macedonia Moves Closer to European Green Electricity Certification System
North Macedonia’s National Electricity Market Operator, MEMO, has officially joined the Association of Issuing Bodies (AIB), marking an important step toward deeper integration with the European framework for guarantees of origin and cross-border renewable electricity trade.
The decision was confirmed during the General Assembly of the Association of Issuing Bodies, where MEMO became a full member of the Brussels-based European energy certification organization. The move comes as the Ministry of Energy, Mining and Mineral Resources and the Energy Community Secretariat continue efforts to advance the mutual recognition of guarantees of origin between the European Union and Energy Community countries.
Guarantees of origin are electronic certificates proving that a specific quantity of electricity has been generated from renewable energy sources. They are increasingly important for transparent energy markets, renewable energy producers, suppliers and companies seeking to demonstrate the use of green electricity in line with ESG and decarbonisation standards.
MEMO introduced its electronic registry for guarantees of origin in April last year, in cooperation with energy certificate company Grexel and in line with European Energy Certificate System rules and AIB standards. Since then, North Macedonia has issued around 500,000 guarantees of origin, with each certificate representing 1 MWh of electricity produced from renewable sources.
According to MEMO Chief Executive Officer Zoran Gjorgjievski, AIB membership enables the Macedonian guarantees of origin system to implement the procedures required for future accession to the European Energy Certificate System. This will allow the secure, transparent and internationally recognized issuance and trading of green electricity certificates.
He emphasized that further integration of North Macedonia’s electricity market with the European energy market is essential, as it creates new opportunities for renewable energy producers, suppliers and businesses while strengthening trust, competitiveness and investment attractiveness in the country’s renewable energy sector.
Denko Rafajlovski, Head of MEMO’s Renewable Energy Support Department, noted that guarantees of origin play a key role in promoting renewable energy and giving consumers greater transparency and choice over the source of the electricity they use. Through the AIB Hub, national registries are connected, enabling the efficient cross-border transfer of green certificates between countries.
MEMO became an observer member of AIB last year as a first step toward full membership. Its accession now represents a significant milestone in the development of a modern, transparent and European-aligned electricity market in North Macedonia.
Cross-border trade in guarantees of origin will become possible once national legislation and technical requirements are fully harmonized with European Union standards.
