Frequently asked questions
Here you will find answers to many questions concerning the commercialization of your hydropower in the virtual power plant. We will also be happy to answer your questions personally. Just get in touch with us!
How does integration into the virtual power plant work?
We integrate your hydropower plant into the VPP using a protocol interface like our Next Box. We use a secure mobile data connection to connect your hydroelectric facility to the virtual power plant. Our mobile data link infrastructure is widely tested and certified by European TSOs and authorities. The data connection is established using an encrypted virtual private network (VPN), via IEC 60870-5-104 or Modbus TCP protocols. The connection of your unit's data with the virtual power plant is not only necessary for a mutual exchange of information. It can also be used to improve network stability by submitting control signals. In the event of an electricity shortage, your hydropower plant can increase in capacity in order to balance the electricity network; in the presence of much or too much electricity on the network, your plant is throttled or stopped.
What is the Next Box?
The Next Box is your link to the virtual power plant. Communication between your hydroelectric 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.
What is the control system of the VPP?
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.
How do auctions and price formation on the balancing energy market actually work?
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 order 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.
