Elektrik Piyasasında Depolama Faaliyetleri Yönetmeliği

Overview

The Regulation on Electricity Storage Activities in the Electricity Market was issued by the Energy Market Regulatory Authority (EPDK) and published in Official Gazette No. 31479 of 9 May 2021. It governs the setting up of electricity storage units and facilities, their connection to the grid and their use in the market. The text is freely readable at mevzuat.gov.tr; this record rests on the consolidated version as of November 2026.

The regulation defines an electricity storage facility as one that converts electricity to another form, stores it and converts it back to feed the system (Article 3). It divides activities into three: storage integrated with generation, storage integrated with consumption facilities and stand-alone storage (Article 4). A grid-interactive battery system at a data centre falls within storage integrated with consumption facilities in this classification.

Consumers may install storage if the network operator gives a positive connection opinion and the storage sits at the same metering point; installing storage above contracted power depends on additional conditions (Article 6, as amended in the Official Gazette of 19.10.2026). Stand-alone storage requires a supply or aggregator licence and at least 2 MW of installed capacity (Article 7). Capacity and metering-point conditions therefore determine which category a storage installation falls into.

Design, installation, connection, acceptance and operation follow the relevant technical legislation, standards and criteria (Article 9). Related references include NFPA 855, the IEC 62933 series and the Electricity Market Connection and System Usage Regulation. The regulation draws only the market and connection framework; technical details such as battery safety and fire protection are not set out in this text. The design team should therefore read the regulation together with technical standards and talk to the network operator early.

Key points

1. An electricity storage facility converts electricity to another form, stores it and converts it back to feed the system (Article 3).
2. Activities are storage integrated with generation, storage integrated with consumption facilities and stand-alone storage (Article 4).
3. A consumer may install storage with a positive connection opinion from the network operator and at the same metering point (Article 6).
4. Storage above contracted power needs additional conditions; the article was amended in the Official Gazette of 19.10.2026.
5. Stand-alone storage requires a supply or aggregator licence and at least 2 MW installed capacity (Article 7).
6. Design, installation, connection, acceptance and operation follow the relevant technical legislation, standards and criteria (Article 9).
7. The regulation was published in Official Gazette No. 31479 on 9 May 2021.
8. Related references: NFPA 855, IEC 62933 series, Electricity Market Connection and System Usage Regulation.

Using it in design

• Treat a grid-interactive data-centre battery as storage integrated with a consumption facility: same metering point and a distribution company connection opinion are required.
• Warn the designer when battery rating exceeds contracted power and add the additional conditions to the checklist.
• Pure UPS batteries with no grid export stay outside market rules but still follow technical standards.
• For a stand-alone storage scenario, assess the licence and the 2 MW lower limit at the feasibility stage.

Who should read it

Electrical engineers planning battery energy storage (BESS) at data centres, energy consultants and regulatory specialists.
