Incident Reserves (mFRRda)

For maintaining the real-time power balance of the Netherlands, TenneT TSO BV (TenneT-NL) mainly uses Frequency Restoration Reserves (FRR) offered to TenneT-NL by market participants. In case of incidents and substantial long-lasting power deviations TenneT-NL manually activates Frequency Restoration Reserves (directly activated). This page shows the volumes of activated mFRRda.

About

The table shows the activated incident reserve capacity. The full activation time is applicable from the moment incident resereve is deployed. At the end of the activation, the deactivation time starts but the publication will show 0. Both the activation and deactivation time are described in the product information.

When you open this website you will see the data for today. TenneT refreshes this information every minute. A line in the overview remains empty, with the exception of the line number, if no current information is available due to malfunctions. TenneT will fill in empty lines at a later date, when the information becomes available within the time window of the overview.

It is inevitable that the real-time information is presented with a delay of several minutes due to the required processing procedures. Data is available via the 'export data' function.
