Emergency power gensets
Benefits instead of costs from your emergency power generator
Emergency power generators often have an untapped source of income: By generating electricity at short notice that can be used to stabilise the power grid. As the operator of one of the largest virtual power plants in Europe, we offer you the opportunity to provide control energy with your emergency power generator and thus turn a cost factor into an additional source of income. And all this without any additional effort or investment costs.
Reserve Power
Sell reserve power from your emergency genset(s)
Fluctuations in the electricity grid are increasing due to the fluctuating supply of wind and solar energy. If, for example, the current electricity consumption exceeds the electricity production, this must be compensated by capacity reserves - so-called positive control energy. Your emergency power generator can easily supply such capacity reserves, provided it has a minimum output of 250 kW and can run synchronous with the grid frequency.
Additional revenues: You achieve attractive revenues with your emergency generator and thus turn a cost factor into a source of income.
Service-oriented: We take care of the connection of your emergency power to the virtual power plant and carry out the test procedure for the control energy, the prequalification, for you.
Safety: Your genset continues to serve its primary function, of course. Emergency operation always takes precedence over control energy calls.
Restrictions: You can also limit the operating hours of your genset to a defined call time per year.

Tertiary reserve capacity balances the fluctuations of the network after a delay of 15 minutes. The TSO measures the frequency and places commands to call capacities. In order to this, your genset(s) have to react latest 15 minutes after the activation signal. As most emergency gensets have a starting time of only a few seconds this should be no problem. The network operator Elia buys two different mFRR products: R3 standard and R3 flex. The first can be activated for up to 8 hours per day, while the second can be activated for maximum 2 hours continuously – between two activations there has to be a pause of at least 12 hours. The grid operator pays a capacity fee for both products, but only the R3 standard entitles the grid operator to an energy fee.
