What happened
Uludağ Elektrik is making International Renewable Energy Certificates (I-REC) and Renewable Energy Resource Guarantee Certificates (YEK-G) available to customers. The certificates are designed to associate an organisation’s electricity use with renewable generation and provide documentation for that association.
I-REC is an international certification arrangement for tracing electricity generated from renewable sources to consumption. The certificate contains information on the generation facility, when the electricity was produced and the relevant energy source. Customers may use I-REC and YEK-G records in work to document electricity consumption associated with renewables.
For energy and sustainability teams, the immediate next step is to determine whether the certificate information meets their internal requirements for recording electricity-source data, including the facility, generation date and source information.
Why it matters
Electricity-source records can be relevant for businesses monitoring energy use within sustainability programmes. Uludağ Elektrik’s offer provides customers with a route to link their consumption records to renewable electricity certificates.
The announcement also reflects the scale of renewable capacity in Türkiye’s power system. Ministry of Energy and Natural Resources figures for July 2026, cited by Enerji Günlüğü, put renewable sources at 62.8% of the country’s installed electricity capacity.
What the certificates record
I-REC documentation identifies key attributes of the electricity generation underlying the certificate: the producing facility, production date and energy source. This information enables users to retain a more specific record than a general statement about renewable electricity use.
YEK-G is also being offered by Uludağ Elektrik alongside I-REC. The available evidence does not set out further operational distinctions between the two certificate types, but says both can be used to support documentation of electricity use linked with renewable resources.
Next steps for customers
- Review electricity-consumption data that needs supporting documentation.
- Check the generation facility, date and source details held in I-REC records.
- Consider how I-REC and YEK-G certificates fit existing sustainability data processes.
