EMRA increased its power to install integrated storage facilities at charging stations

According to the statement made by EMRA, electricity storage facilities integrated into charging stations can be installed at a vehicle charging power higher than the agreed power of the charging station.

Thus, especially at high-power charging stations, charging services can be provided directly by utilizing electricity storage systems without the need to increase the grid connection capacity.

In the previous practice, the installed power of the storage facility that could be integrated into the charging station was limited to the agreement power of the consumption facility.

This situation could limit the effective use of storage investments, especially in terms of high-power charging stations, to meet the power required by the charging infrastructure.

With the new regulation, opportunity has been provided for those who want to establish a storage facility with a discharge power higher than the contracted power and who want to feed the charging unit with this facility.

In order to protect the network security, it was required to install automatic power control and power cut-off systems that prevent the supply of energy to the network and prevent the current agreement power from being exceeded when drawing energy from the network.

Storage systems can be an alternative to network investments

The widespread use of storage-integrated charging stations creates an alternative that can eliminate the necessity of making costly network investments in every location.

Especially in locations where new transformer and connection investments are costly or where instant and periodic charging needs are high and charging queues form, the use of storage systems can make it easier to realize investments and provide services to users.

This model will also contribute to more effective use of the existing electricity distribution infrastructure.

The introduction of storage systems in short periods when charging demand is high helps keep the power drawn from the grid within the agreed power, while allowing charging stations to have charging equipment with higher installed power.

With the spread of electric vehicles, the need for high-power charging infrastructure is increasing, especially on highways, rest facilities, fuel stations and heavily used commercial areas.

Creating the necessary capacity to connect these stations to the network will bring new network and transformer investments to the agenda in some locations.

Using storage systems together with charging stations offers an alternative solution at this point.

While electricity is drawn from the grid at a certain power level, activating the storage system at moments when charging demand is high can enable the instant power needed by the charging station to be met more effectively.

For example, in a location where the contracting power is not sufficient to meet the total instantaneous demand of a high-power charging station, the storage system can support the charging process in periods when charging demand increases by storing energy from the grid during low demand periods.

Thus, the power needs that may arise when charging multiple vehicles at high power at the same time can be met through the storage system.

It will support the development of electric vehicle charging infrastructure

The regulation is expected to provide significant investment flexibility, especially in terms of the proliferation of high-power charging stations.

Charging network operators will be able to make a more effective investment choice between increasing network capacity and storage investment by evaluating the location's grid connection capacity, investment cost and charging demand together.

This paves the way for the fast and high-power charging infrastructure needed by electric vehicle users to be installed in more locations, taking into account the current capacity of the network and investment conditions.

While the new application will encourage the combined use of electric vehicle charging infrastructure and electricity storage technologies, it will contribute to the creation of a more flexible, efficient and investment-viable model in the integration of charging stations into the grid.
