A new round in one of Europe's fastest-growing solar markets
Turkey has launched its latest renewable energy tender, seeking 900 MW of new solar PV capacity and 1.5 GW of wind across the country's designated Renewable Energy Resource Areas (YEKA). Applications for both technologies are due on 13 October, and the government has set a ceiling price of EUR 0.055/kWh across the round, with a floor of EUR 0.0325/kWh for solar projects.

How the round is structured
The YEKA model concentrates capacity in pre-identified resource zones, which shortens permitting and grid discussions for winning bidders. A notable feature of this round is flexibility on revenue: awarded projects can sell power on the open market first before settling into a 20-year power purchase agreement. That structure rewards developers who can build quickly — early energisation means early merchant revenue — which makes construction speed a genuine part of the business case, not just a schedule preference.
Tight ceiling prices put the structure under scrutiny
With bids capped at EUR 0.055/kWh and competition likely to push prices toward the floor, every element of capex gets examined. The ground-mounting structure is one of the largest steel line items in a utility-scale bid, and it is also one of the most optimisable: section sizes matched to the actual wind and seismic basis, span layouts that reduce foundation count, and a foundation type chosen from real geotechnical data rather than habit. On suitable soils a ground screw system installs fast with no concrete cure time, while driven pile foundations remain the workhorse for large open sites.
Turkey's site conditions reward careful engineering
Turkish project sites range from Aegean coastal plains to high Anatolian plateaus with real snow loads and seismic requirements. A structure specified for the wrong basis is either unsafe or over-built — and at tender ceiling prices, over-building is a bid-killer. Buyers should ask every mounting supplier to state the design standard, wind and snow assumptions, steel grade and corrosion class in writing, so bids can be compared like for like. Our guide to wind and snow loads covers the parameters that matter.
The takeaway
Turkey's pipeline keeps growing, and YEKA rounds are won on disciplined engineering as much as on financing. For a utility-scale bid package, send Apex the site location, geotechnical summary, module format and target layout, and the engineering team will prepare a structure proposal sized to Turkish site conditions — with material specifications and load calculations documented for the bid.
