Discover the service aFRR in the Netherlands

aFRR (standing for “Automatic Frequency Restoration Reserve”) is the secondary Dutch electric reserve. These reserves - 3 in number - are implemented by the TSO, Tennet, to balance its power grid. 

 

After FCR, aFRR is used to restore automatically the frequency of the power grid. This service enables Tennet to solve small daily imbalances.

 

Flexcity was the first independent aggregator to propose the electric flexibility of its partners in this service (opened in 2022 for independent aggregators).

VPK

VPK monetizes its electric flexibility thanks to Flexcity's expertise.

An efficient partnership between a company from the energy-intensive paper industry and its independent aggregator makes it possible to find out ways to monetize VPK's assets on the energy markets. By making the cogeneration of its Belgian site participate in the aFRR service, VPK Paper has reduced its energy bills.
