Reactive flexibility

Use your asset to stabilize the power grid

The increased volatile feed-in of renewable energies also brought a challenge to managing grids: a stronger fluctuating grid frequency. These fluctuations need to be minimized in order to keep a stable grid. Aggregated in a Virtual Power Plant, distributed assets can play a vital role in levelling out these fluctuations. Smaller units often have a shorter reaction time and combined in a VPP they offer a higher granularity in catching fluctuations. 

Today, not only can large power plants provide ancillary services in order to stabilize the grid frequency. Aggregated in a Virtual Power Plant, distributed small-scale producers and C&I-consumers alike can help stabilizing the grid frequency. Next Kraftwerke is active in seven European TSO areas providing ancillary services.

Options for reactive flexibility

Ancillary services from distributed assets

A stable grid is vital for a functioning power supply. Aggregated in a VPP, distributed assets can also make important contributions to the stability of a power grid. 

Different countries have varying ancillary products and requirements. But generally speaking, if you are operating an asset that has the capability of ramping up or down its power production, you can provide stabilizing services through a Virtual Power Plant.

How ancillary services work Getting started Can you particpate?
How ancillary services work

Once your asset is prequalified (technically and functionally checked for complying with the transmission code), the unit will be part of the VPP providing grid frequency control or similar ancillary services. 
In case of a frequency imbalance the VPP will receive an order from the TSO requesting a certain amount of power in order to balance out frequency deviations. 
This call will be divided into smaller chunks, since the individual assets of the VPP usually can only provide a fraction of the needed power. The algorithm of the VPP decides which asset will provide how much power. The activation of each individual asset happens automatically via M2M communication.
Getting started

Bringing your asset to the ancillary service markets is basically done in three simple steps

  1. An encrypted connection is established via the Next Box remote control unit 
  2. The unit needs to be prequalified to comply to the TSO regulations for providing ancillary services 
  3. The asset owner receives revenues according to his contribution to grid stability
Can you particpate?

For providing ancillary services, your asset needs to provide the following features:

  • Continuous power production 
  • Possibility for remote control of your asset 
  • Fast reaction time of your asset's power production

Demand response

Power consumption processes of C&I consumers can play an important role in providing ancillary services and help owners to generate additional profit. The provision of reactive flexibility does not interfere with the main purpose of the industrial purpose. The operator or factory owner sets the restrictions in which the process can provide flexibility. The actual call for flexibility only uses a fraction of the entire consumption process.

Power consumption processes

More consumption processes than you might imagine are suitable for providing ancillary services. The following aspects are indicators that your process might also be able to provide demand response services: 
  • Continuous power consumption 
  • Possibility to temporarily reduce load within the consumption process 
  • Possibility to ramp up the consumption on short notice 
  • Do you have a buffer (batteries or storage tanks, silos)?
  • Automated consumption control via process control technology
  • Do you have your own power production on the companies premises (CHP, emergency generators, power to heat, etc.)
Power to X

Whether it is power to gas or power to heat –power-to-X technologies have a great advantage: they already provide their own storage. Especially power to heat units are suitable, since heat is a rather inert mass. This means, that short deviations in their production in order to provide ancillary services won't affect the heat production. This makes power-to-X a really versatile provider of ancillary services.
Power producers

Do you operate behind-the-meter generators such as emergency generators or CHPs on your premises? Use this potential for generating additional revenues, because these assets offer something valuable to any power grid: flexibility. Integrated in a Virtual Power Plant these assets can easily provide ancillary services. Of course, the main purpose of your asset will not change. Providing ancillary service will always be its secondary purpose. But this is a chance to generate revenues, where you usually only produce costs.
Your advantages

  • Generate revenues where you usually only have costs 
  • Be a part of the energy transition and help stabilizing the grid 
  • Everything under one roof: From customer care to our technical plant integration and power trading – with Next Kraftwerke you'll never have to deal with external hotlines or other third parties 
  • Full transparency: no hidden costs for market access. Fixed profit sharing model
