The Renewable Energy Resource Guarantee (YEK-G) System developed
in-house by EPİAŞ (Energy Exchange Istanbul) provides a
transparent and trustworthy certification mechanism that verifies
the renewable origin of electricity. Entirely designed and
implemented by EPİAŞ’s internal teams, the system is built on
blockchain technology to ensure data integrity, traceability, and
security throughout the certificate lifecycle.
By enabling producers to prove the renewable source of their
energy and consumers to make informed, sustainable choices, the
YEK-G platform promotes green energy investments and supports
Turkiye’s transition to a low-carbon economy.
