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.

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.

Reserve Power

  1. Together with you, we analyse how your emergency gensets can gain has the highest earnings on the reserve power market.
  2. Your genset is connected to the virtual control unit via the Next Box, which allows the system control to react to the TSO setpoints.
  3. To actively participate in balancing markets, your plant must be pre-qualified with the TSO. We take care of this process for you.
  4. After a successful prequalification, your genset is valued on the reserve electricity market and is rewarded with a capacity fee and, in certain cases, an activation fee.
Connection to the VPP

In order to sell the capacity of your genset successfully on the reserve power market, a connection to the Virtual Power Plant via the Next Box is necessary. If the transmission system operator activates a certain amount of reserve capacity, our control system automatically determines the best operating plan and schedules the systems in the Next Pool accordingly.

Next Box: The Next Box is your link to the virtual power plant. Communication between your genset plant and our control system takes place via a secure mobile connection that meets a legally prescribed requirement for the telecontrol capacity of a plant. The Next Box also enables you to operate your system according to a price-based scheme, which opens up additional trading opportunities.

Control system: All plants in the virtual power plant supply data to our control system so that we always have an overview of the available aggregated capacity. Almost all commands executed by the Virtual Power Plant controller are automated via M2M communication. Strict safety standards are complied at any time.
mFRR (R3)

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.
Auctions & Prices

Primary, secondary and tertiary reserves are negotiated by the Belgian TSO Elia during auctions on the control reserve markets. Market participants submit initial bids for the capacity price, which are sorted by amount in a merit list. For the secondary and tertiary reserve, successful suppliers participate in a second auction and submit bids for the unit price. If the control pool is required, the suppliers with the lowest price receive the RFx first. Higher offers follow in order. If a control reserve order is placed, secondary and tertiary reserve suppliers also receive the additional unit price. While the FCR and the RRF are subject to a weekly call for tenders, the RRFm is subject to a monthly call for tenders. In addition, Elia offers part of its FCR power on the regional market regelleistung.net.
