Regulation on Unlicensed Electricity Generation in the Electricity Market (Elektrik Piyasasında Lisanssız Elektrik Üretim Yönetmeliği)

Overview

This regulation sets out the rules of the Energy Market Regulatory Authority (EPDK) for generating electricity without a licence or company formation. For data centres it matters in two ways: emergency generator sets (imdat grupları) are explicitly licence-exempt, and on-site renewables, such as rooftop or facade PV for self-consumption at the same metering point, can be built under this regime with distribution-level connection rules.

Article 5(1)(a) lists emergency generator sets among the facilities exempt from pre-licence, licence and company-formation obligations. Article 5(1)(b) exempts plants operating with no connection of any kind to the transmission or distribution system, and Article 5(1)(ç) exempts renewable plants that consume all their output without feeding the grid, with generation and consumption at the same metering point. Under Article 7(1), plants connect to the distribution system at MV or LV depending on technical characteristics and existing capacity, and rejections must be reasoned in writing.

Article 7(2) sets an important limit: total LV-connected generation on a distribution transformer owned by the distribution company may not exceed 50% of the transformer rating. Related instruments include Article 14 of Law 6446 and the Electricity Market Connection and System Usage Regulation. This page is not the legal text; the current official text should be consulted in practice.

Key points

1. Emergency generator sets (imdat grupları) are listed as exempt from pre-licence, licence and company-formation obligations (Article 5(1)(a)).
2. Plants with no connection of any kind to the transmission or distribution system are exempt (Article 5(1)(b)).
3. Renewable plants consuming all output without feeding the grid, with generation and consumption at the same metering point, are exempt (Article 5(1)(ç)).
4. Plants connect at MV or LV depending on technical characteristics and existing capacity; rejections must be reasoned in writing (Article 7(1)).
5. Total LV-connected generation on a DSO-owned distribution transformer may not exceed 50% of transformer rating (Article 7(2)).

Using it in design

• In the generator module, tag standby diesel sets as 'imdat grubu': no generation licence, no export.
• Enforce no parallel export unless a separate connection approval exists.
• In the renewable module, model on-site PV as self-consumption behind the data centre meter.
• Warn if LV injection exceeds 50% of the supplying distribution transformer.

Who should read it
