Türkiye allows higher-powered batteries behind existing grid connections

Türkiye’s Energy Market Regulatory Authority (EPDK) has published rules letting consumers install batteries with a higher power rating than their contracted grid connection. The changes took effect on 19 October 2026. Sites must still keep grid imports within the agreed limit and fit automatic controls that prevent any electricity export.

What does the new rule allow?

Businesses can now add battery power — measured in kilowatts or megawatts — above their grid‑connection allowance. The battery and the consumption facility must share the same metering point, and the grid operator must approve the installation. Any battery exceeding the contracted power limit requires an automatic power‑control system and a dedicated electricity cut‑off mechanism.

How does it affect businesses?

The rule lets a facility draw extra power from its battery during short demand peaks without breaching its grid import cap. This avoids the cost and delay of upgrading the grid connection. The change applies strictly to power rating, not to energy capacity in kilowatt‑hours or megawatt‑hours.

What other regulatory changes accompanied this?

A separate amendment permits storage paired with licence‑exempt generation to be built without an energy‑capacity ceiling, provided the battery’s power does not exceed the generating plant’s electrical capacity. Developers can therefore add more hours of storage. On the same day, EPDK updated financial‑guarantee rules for generation projects that include storage: guarantees are returned only when the whole facility is operational, and partial refunds for individual storage units are based on the power of units that have passed formal acceptance.

What is the context of Türkiye’s storage pipeline?

EPDK reported in February 2026 that it had allocated roughly 33 GW to wind and solar projects combined with battery storage under legislation introduced in 2022. At that point, 23 projects totalling about 1.07 GW had received generation licences, with some 208 MW already operating. The new rules are intended to accelerate deployment by removing a key bottleneck for commercial and industrial users.
