Recent Croatian guarantees-of-origin auctions cleared renewable certificates at around €1.55–€2.06 per GO, providing a new market reference for corporate buyers and electricity suppliers seeking renewable-energy attributes. Held on 27 October through CROPEX’s trading platform, the auctions comprised six parallel sessions covering wind, biomass and solar certificates.
The largest transaction was the sale by HROTE of 203,752 guarantees of origin from Croatian wind generation in the third quarter of 2026, at €1.60 per GO. HROTE also sold 47,377 biomass GOs at €1.61. ENNA Next sold 6,791 German wind GOs for generation from June through September at the session’s highest price, €2.06 per GO. It also sold 6,063 solar GOs at €1.55 and 997 biomass GOs at €1.60.
KOER offered a further 1,271 solar GOs covering September generation, which cleared at €1.56. The newsletter reported total sales of 266,252 GOs across the auctions. The relatively narrow pricing range for Croatian wind, solar and biomass certificates points to a liquid renewable-attribute market, with only modest price premiums between technologies; imported German wind certificates cleared materially higher, suggesting that origin and buyer preference can still create distinct value in the wider GO market.
