Data-centre investments in Türkiye: incentive mechanisms (Türkiye'de Veri Merkezi Yatırımları: Teşvik Mekanizmaları)

Overview

This legal briefing by Çakmak Avukatlık Bürosu, dated 8 January 2026, summarises Turkish state incentives for data centres under the HIT-30 project-based programme, its October 2025 HIT-Data Centre call, and the Priority and Target investment schemes of Decision 9903. The incentives come with hard technical conditions, which translate directly into design targets for Turkish projects. The HIT-Data Centre call (17 October 2025) offers about $1.5 bn of support and requires at least 30 MW IT capacity, at least 50% AI-hardware-ready capacity, PUE of 1.4 or lower and integration with major cloud and AI service centres.

HIT-30 supports require a minimum fixed investment of TRY 2 bn; incentives include up to 50% tax incentive and energy support of up to 10% of the investment. The Decision 9903 schemes require a TSE Data Centre Design Certificate under TS EN 50600 with minimum Availability Class 3, Protection Class 4 and Energy Granularity Level 3.

Also required are a full-occupancy PUE of at most 1.65 (no partial calculation) and fibre from at least two telecom operators terminating in the data centre; a TSE Data Centre Facility Certificate follows completion. The Priority Investment scheme needs at least 3 MW installed power (60% tax reduction up to a 30% investment contribution rate), and the Target scheme at least 500 kW (20% contribution rate). This is a legal summary; current legislation and the call text must be verified before applying.

Using it in design

• Add a 'Türkiye incentive compliance' check: TS EN 50600 AC≥3, PC≥4, GL≥3.
• Verify design PUE of at most 1.65 at full load (at most 1.4 for HIT-Data Centre).
• Check for at least two diverse telecom fibre entries and the capacity thresholds (0.5 / 3 / 30 MW).
• Show pass/fail in the design report.
