Advancing Energy Transparency in Belgium: GO System Deployment for CREG 

Grexel, part of EEX Group, has been appointed by the Commission for Electricity and Gas Regulation (CREG)* to establish an electronic Guarantees of Origin (GOs)** system in Belgium. 

Selecting the Right Partner 

In order to replace their previous registry solution, nearing the end of its technical lifetime, in the summer 2023, CREG initiated a tender process to identify a suitable contractor for this critical project. After a rigorous evaluation, Grexel emerged as the chosen partner, aligning closely with CREG’s vision and tender specifications. 

Seamless Integration 

The project achieved a significant milestone by seamlessly launching on its target date of October 13, 2023, precisely as planned. This accomplishment is even more noteworthy considering the project’s completion in less than a month, incorporating both data migration and tailored customization to meet the specific requirements of the customer. This success showcases the effective teamwork between CREG and Grexel and sets a strong example for integrating electricity guarantee systems in the EECS framework. 

Empowering Guarantees of Origin Management 

CREG now benefits from G-REX, a user-friendly and modern electronic registry for guarantees of origin. G-REX seamlessly facilitates the transfer of GOs through the AIB Hub.  

Compliance with EU Directives 

The deployment of the GO registry aligns with the rigorous standards set forth by the European Union, encompassing compliance with both EECS and the Directive on Renewable Energy (RED II). 

* Commission for Electricity and Gas Regulation (CREG) is a regulatory authority responsible for overseeing and regulating the electricity and gas markets in Belgium. CREG’s main role is to ensure fair competition, consumer protection, and the development of a sustainable energy sector in the country. 

**Guarantees of Origin serve as a pivotal tracking mechanism, providing evidence of electricity origin. This, in turn, enables energy users to consume energy specifically from renewable sources instead of an average generation mix. Such certification and tracking is instrumental in advancing the production and consumption of environmentally friendly electricity, bolstering traceability and fostering increased investments in renewable energy.
