TEİAŞ Reports 539 MW Remaining Unlicensed Grid Connection Capacity

TEİAŞ has published updated capacity figures showing that 539 MW of unlicensed generation capacity remains available for grid connection across transmission and distribution networks in Türkiye. Unlicensed generation in the Turkish electricity market allows industrial facilities, commercial operations and private developers to construct self-consumption renewable projects without navigating the full licensing process.

The release of these capacity tables provides clarity for industrial energy consumers and developers planning solar and self-consumption generation facilities. As available headroom on distribution networks shrinks, regional sub-allocations determine where new embedded generation can physically integrate without triggering major network reinforcements.

For grid infrastructure, the remaining 539 MW allocation presents operational and hardware considerations for network operators and project developers alike. Connecting embedded generation into existing distribution substations alters local fault levels, reverse power flow patterns and voltage profiles. Substation transformers situated at feeder junctions face bidirectional load profiles that complicate tap-changer operations and voltage regulation.

Furthermore, integrating new capacity into constrained distribution nodes increases demands on step-up transformers, protection relays and switchgear equipment. Engineering teams must evaluate whether existing substation step-up transformers have sufficient thermal capacity and dielectric health to withstand additional load cycling associated with variable renewable inputs.

What this means for asset owners in Türkiye: In Türkiye, industrial site owners and project developers competing for the remaining 539 MW grid capacity must assess local substation switchgear capability, protection grading and transformer headroom prior to submitting connection applications. Network operators will scrutinise thermal ratings and reverse power capacities at primary substations, making early technical audits of step-up transformers and circuit breakers essential to avoid interconnection delays or costly grid integration upgrades.
