Türkiye remained structurally disconnected from the rest of the SEE electricity price curve in Week 25. While Italy traded above €120/MWh, Hungary above €100/MWh, and Croatia and Romania also moved into higher bands, Türkiye averaged only around €16.66/MWh. The gap was too large to be treated as a normal weekly price difference. It was a structural spread.
The Turkish market’s low price was supported by stable hydro production, domestic market conditions and limited transmission of its price signal into the wider SEE trading zone. Türkiye remained a net exporter, but the discount did not flow fully into neighbouring markets. That is the key point. In a fully integrated market, such a large price difference would attract flows until the spread narrowed. In practice, interconnector limits, market rules and incomplete coupling prevent full convergence.
For SEE traders, this creates one of the most interesting regional questions: how much value is trapped behind border capacity and market structure? The Türkiye-Europe spread is not only about price; it is about infrastructure. If transmission capacity were larger and market coupling deeper, Turkish supply could have a stronger price-dampening effect on Bulgaria, Greece and the wider Balkans. Instead, the discount remains only partly accessible.
The Turkish case also shows why SEE cannot be analysed only through EU market logic. Türkiye has a different generation mix, regulatory framework and domestic pricing environment. Its market can move in ways that are not fully aligned with EU-linked exchanges such as HENEX, IBEX, SEEPEX, OPCOM, CROPEX and HUPX. That creates arbitrage potential, but also execution risk.
For investors, the spread points toward interconnector value. Cross-border infrastructure, grid reinforcement, trading platforms and balancing cooperation can unlock value that already exists in price differentials. The economic case is not abstract. A spread of this size implies that even modest additional flow capacity could have commercial impact, especially during periods of high Italian, Greek or Balkan demand.
For industrial buyers in SEE, Türkiye’s discount may look attractive, but physical delivery and contractual certainty matter more than headline prices. Long-term procurement strategies cannot be built only on the existence of cheap power in a neighbouring system. They require transmission rights, balancing rules, creditworthy counterparties, settlement clarity and regulatory compatibility.
Türkiye is therefore not just the low-price outlier of SEE. It is a reminder that the next stage of regional power-market development will be decided by interconnection, coupling and commercial access. The price is visible. The value is not yet fully tradable.
