Turkey's total installed renewable energy capacity reached a record 65 GW at the end of Q4 2025, driven by a surge in solar photovoltaic and onshore wind additions. According to data released by the Turkish Electricity Transmission Corporation (TEIAS), capacity grew 12% year-on-year from 58 GW in Q4 2024.
Solar was the largest contributor with 8 GW of new installations, bringing cumulative solar capacity to 28 GW. The government's YEKA tender scheme, combined with falling module prices, has accelerated deployment well above the official 2025 targets.
Onshore wind added 2.4 GW during the year, reaching a total of 19 GW. New projects benefiting from the revised feed-in tariff are entering commissioning in the Aegean and Marmara regions.
Hydropower remains Turkey's largest renewable source at 32 GW, though no significant new capacity was added in 2025 due to limited undeveloped river resources.
The milestone is significant in the context of Turkey's NDC commitment to achieve 64.6 GW of renewable capacity by 2030 — a target already surpassed five years early.
