Bölüm 1: Türkiye’de ve dünyada bağlantı kapasitesi sorunu

The report details a critical shortage of grid connection capacity in Turkey and worldwide. In Turkey, 65% of unlicensed project applications were rejected between February 2024 and April 2025 due to regional capacity constraints. Globally, 1.65 TW of wind, solar, and hydro projects are awaiting connection. The document identifies economic risks, long construction timelines, cautious technical planning, and procedural inefficiencies as primary barriers to the energy transition.

• In Turkey, grid connection capacity at the transmission level has been exhausted since September 2024, leading to the rejection of all new applications at this level. Between February 2024 and April 2025, 65% of unlicensed project applications (7.5 GW out of 11.6 GW) were denied due to 'regional capacity constraints'. This rejected capacity represents one-third of Turkey's solar energy installed capacity as of May 2025 (22.5 GW).
• Economic factors and investment costs are major hurdles for grid expansion in Turkey. TEİAŞ's 2024–2028 Strategic Plan allocates 74% of its 362 billion TL budget to renewing and developing the electricity grid. The agency identifies exchange rate fluctuations and high inflation as significant economic risks affecting contracts with contractors.
• Globally, the capacity of wind, solar, and hydroelectric projects awaiting connection reached 1.65 TW by July 2024, a 10% increase from 2023, representing 38% of the current global installed capacity for these sources. In Europe, 10 countries—including Germany, Spain, and France—have a combined 0.5 TW of wind projects awaiting approval.
• Infrastructure development is slowed by high costs, supply issues, and labor shortages. Connection permits in Europe can take up to 9 years, with average wait times in the UK being 5.5 years and reaching up to 15 years in some cases. Construction times for high-voltage projects range from 5 to 13 years.
• Technical and procedural inefficiencies exacerbate the problem. System operators often use overly cautious assumptions regarding the maximum production of variable sources like wind and solar, leading to underestimated capacity. Additionally, 'first-come, first-served' systems in much of Europe allow low-probability projects to clog the queue. To counter this, countries like France, Greece, and Romania have tightened application criteria, while Romania, the UK, Greece, Spain, and Italy use application fees or bank guarantees to deter speculative projects.
