Engie - Netherlands

Application

Grid services - dynamic firm frequency response.


Opportunity

Revenue can be generated from energy storage systems by charging or discharging them in response to signals issued by the grid operator. A stack of revenue streams can be accessed via an aggregator and this stack varies depending on whether the system is installed before or behind the meter on a customer’s site and the nature of the site.

Solution

Connected Energy supplied Engie with a system specifically designed to provide dynamic firm frequency response and which could be controlled by their in house aggregator. The system was required to pass the local grid operator’s standard prequalification tests in order to provide the services.

The E-STOR system was integrated with Engie’s aggregator and is now providing non stop frequency response services.
