What happened
Türkiye’s Energy Market Regulatory Authority, known as EPDK, has revised the framework for electric-vehicle charging stations that incorporate electricity storage. Under the new arrangement, a storage facility serving charging equipment may discharge at a power level greater than the site’s contracted power with the electricity network.
Previously, the installed power of storage integrated into a charging site was capped at the consumption facility’s contracted capacity. According to Enerji Günlüğü, that restriction could limit the role of storage at high-power charging locations, where demand can exceed the capacity available through the grid connection.
The rule is subject to operating safeguards. Operators seeking to use storage with a higher discharge capability must install automatic power-control and energy-disconnection systems. These must stop electricity from flowing from the site into the grid and ensure that power drawn from the grid remains no higher than the contracted level.
The change therefore does not increase the amount of electricity a site can import from the network beyond its existing contract. Instead, stored electricity can supplement that import when charging demand rises.
Why it matters
The approach could give charging operators another way to serve short periods of high demand without first expanding their grid connection. A station can draw electricity at its contracted level, store energy during lower-demand periods, and use that stored supply when several vehicles require high-power charging at once.
This may be relevant in places where new transformers or connection works are expensive, or where charging demand is concentrated at particular times. The source identifies motorways, rest facilities, fuel stations and heavily used commercial areas as locations where demand for high-power charging infrastructure is increasing.
For network planners and charging investors, the revision creates a choice between raising connection capacity and combining the available connection with storage. The relative case will depend on local grid capacity, expected charging demand and investment costs. The evidence does not set out an effective date, technical threshold or approval process.
What operators should assess
Operators considering this model should examine whether their contracted supply can support charging demand when paired with storage, as well as the cost of storage against potential grid and transformer investment. They will also need to incorporate the required automatic controls and disconnection equipment into site design.
Compliance depends on both conditions being met: no export of electricity to the network and no grid import above the contracted capacity. Storage can provide additional charging output only within those limits.
