The Next Box also makes it possible to operate your asset according to a price-based schedule, which opens up additional trading options. 

Control system: All assets in the Virtual Power Plant provide data to our control system, giving us a constant overview of the available aggregated capacity. Nearly all commands executed by the Virtual Power Plant control system are automated using M2M communication. The strictest security and safety standards are maintained at all times.
Forecasting & Trading

Our experienced team of analysts and brokers trades the electricity you have generated on the EEX and EPEX Spot power exchanges. The data contained in the Virtual Power Plant plays an important role here: Live feed-in and draw-off data from thousands of units form the basis of our precise forecasts. This is supplemented by constantly-updated market data from several exchanges and the results of our own meteorological analyses. By combining these data sets, we can trade renewable energies competitively and contribute to further integration of decentralized assets on the market.
Client portal & Mobile app

Using our client portal "My power plant", available on PC or via mobile app, you can follow the status of your biogas installation in real-time, change personal data, and consult your monthly credit notes. You also have the option to announce unavailability of your plant due to a planned maintenance etc. This way, we know when your plant is not available to be traded. Via the App, you will be informed about any malfunction or interruption of the connection of your installation to the virtual power plant. That way,  you can always react as fast as possible in case it would be needed.
Revenues

This is how your revenues are composed: the green certificates as awarded by the DSO for every produced MWh, the Guarantees of Origin as exchanged in the GO database, and the revenues from trading on the power exchanges. 

At Next Kraftwerke you have the best rates: thanks to our high-performant trading and the integration of your real-time data, and the portfolio effect which reduces the imbalance costs, Next Kraftwerke can offer you competitive rates.

Optimised production: steering your power plant to higher revenues

The market price of power changes 24 times per day on the day-ahead market, and 96 times daily in intraday trading. The difference in price between individual quarter-hour segments can be more than 50 euros per megawatt hour. Therefore, it is worthwhile to align power production with periods of high market demand. We work together on an operating schedule for your biogas plant, with a target output above the monthly average. Our forecasts are based on live data from thousands of assets in our Virtual Power Plant.

Overview

  1. We analyse the flexibility potential together with you. 
  2. Your installation is connected to the virtual power plant via our an online interface or our Next Box.
  3. You receive from us operational schedules that optimise the revenues of your installation based on the electricity prices.
  4. You make the necessary changes in your operational schedule. With very flexible biogas plants, it is even possible to steer them completely autonomous with the Next Box.
  5. The flexible installation results in very attractive remuneration in the power exchanges.
Connection & Data Exchange

In order to optimise the operational schedule of your biogas plant, our trading team needs production data of the installation. On the other hand, we need an interface to deliver the optimised schedules to you. This can happen via an online interface, or the Next Box. Installation of the latter allows also for fully autonomous steering of the installation in reaction to the electricity prices. 

Next Box: The Next Box is your link to the Virtual Power Plant. Communication between your biogas asset and our control system is conducted over a secure mobile connection, fulfilling a legally-prescribed requirement on an asset’s remote-control capacity. The Next Box also makes it possible to operate your asset according to a price-based schedule, which opens up additional trading options. 

Control system: All assets in the Virtual Power Plant provide data to our control system, giving us a constant overview of the available aggregated capacity. Nearly all commands executed by the Virtual Power Plant control system are automated using M2M communication. The strictest security and safety standards are maintained at all times.
Peak 7

We create a custom, weekly operating schedule for your asset based on current pricing forecasts and the asset's operating restrictions. The asset's operating schedule can be manually executed or automated by our control system using the Next Box. Even if you opt for automated execution, you maintain full control of your motor’s starts and stops in the customer portal. Higher profits are possible if you are able to spontaneously adjust operation based on changes in the weather or sudden moves on the market. In this case, additional options for peak-load operation are available.
Peak 24

Up-to-date market forecasting is an important factor in determining profit margins of power production. With our Peak 24 rate, we create a custom, daily operating schedule, incorporating the latest price forecasts and the operating restrictions specific to your asset. This requires more frequent updates to the operating schedule, meaning control of your asset needs to be managed by the Next Box if you opt for the Peak 24 rate. You still retain full control of your asset through the customer portal and can adjust starts and stops of your biogas unit.
Peak 96

The Peak 96 rate is best way to optimize peak-load operation. Your biogas asset receives operating commands every fifteen minutes. This takes full advantage of price fluctuation and maximizes profit. Operation of your asset on the optimized schedule is fully automated using our control system and the Next Box. The customer portal provides full access to your asset's operation with Peak 96 as well. You always maintain control.
Additional revenues

At Next Kraftwerke you will receive competent and personal advice from experts in the energy industry: We provide you with technical support on your way to the virtual power plant, take care of monitoring your plant data and check together with you which flexibility options are possible for you and your plant. It is also part of a complete service for us that we support you with applications and communication with the authorities.

Balancing power: the flexibility of your plant is valuable!

Solar and wind assets produce varying amounts of power depending on the weather, which leads to fluctuations in grid frequency. To balance out this fluctuation, Transmission System Operators (TSOs) need control reserve - something you can provide with your biogas plant.  Nuclear and coal power plants cannot quickly adjust their output. The same goes for wind and solar plants, which are dependent on the weather. However, your biogas asset can make quick adjustments to power production, and this flexibility a valuable asset on the control reserve market.

Reserve power

  1. We analyse together with you on which reserve market your biogas plant has the highest value.
  2. The installation is connected to the virtual power plant via the Next Box, which allows steering of the plant to react to the TSO's set points.
  3. To actively participate in the balancing markets, your plant needs to be prequalified with the TSO. We take care of this process for you.
  4. After successful prequalification, your biogas plant is valorised in the reserve power market and is rewarded with a capacity remuneration, and in some cases an activation remuneration. 
Connection to the VPP

In order to successfully valorise your biogas power in the reserve power markets, connection to the virtual power plant via the Next Box is necessary. When the TSO activates a certain amount of reserve power, our control system automatically determines the best operational schedule and dispatches the installations in the Next Pool accordingly.

Next Box: The Next Box is your link to the Virtual Power Plant. Communication between your biogas asset and our control system is conducted over a secure mobile connection, fulfilling a legally-prescribed requirement on an asset’s remote-control capacity. The Next Box also makes it possible to operate your asset according to a price-based schedule, which opens up additional trading options.

Control system: All assets in the Virtual Power Plant provide data to our control system, giving us a constant overview of the available aggregated capacity. Nearly all commands executed by the Virtual Power Plant control system are automated using M2M communication. The strictest security and safety standards are maintained at all times.
FCR (R1)


Primary reserve capacity is the first to be activated to prevent a power outage and is the most attractive type of control reserve to sell. It must be available within 30 seconds, and delivery must continue uninterrupted for at least 15 minutes. Checks are conducted as part of prequalification tests to identify how much positive and negative capacity can be produced in this time frame. This ‘capacity range’ can be sold on the control reserve markets after a bidding process conducted in advance. Unlike the tertiary or secondary reserve, primary reserve is not activated by a command from the TSO. Instead, it is triggered by grid frequency. This is measured directly on the biogas asset; depending on the deviation, the asset immediately delivers positive or negative primary reserve. Due to the constant availability, there is no difference between the capacity price and the energy price -  compensation is automatically set at the capacity price.

The Belgian TSO Elia procures four different FCR products: two symmetrical and two assymetrical. The symmetrical products are FCR 100 mHZ and FCR 200 mHZ, respectively responding in a frequency deviation band of +- 100 mHz and +- 200 mHz around 50 Hz. The assymetrical products require an activation in only one direction, respectively upwards or downwards for FCR upward and FCR downward. The different products are shown in the figure above.
aFRR (R2)

Secondary reserve capacity must be available within five minutes to take over from the primary reserve. Orders are placed by the TSO of each control area, and frequency values are measured centrally instead of on site. Providing secondary reserve capacity yields the capacity price, and the unit price is applied if an order is placed. Both prices are determined by auctions on the control reserve markets.

Currently, secondary reserve power can only be offered by power plants with a CIPU-contract. Grid operator Elia has performed a pilot case to assess the possibility to deliver R2 with installations connected to the MV and LV grid. Next Kraftwerke participated in this pilot project and reached a response compliancy better than some conventional power plants that deliver secondary reserve power today. Therefore, Elia is now in the process of opening the market for non-CIPU-installations.
mFRR (R3)

Tertiary reserve capacity balances grid fluctuations following a lead time of 15 minutes. The TSO measures frequency and places orders to call up capacity. 

Grid operator Elia procures two different mFRR products: R3 standard and R3 flex. The first one can be activated for up to 8 hours per day, while the latter 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 remunerations for both products, but only for R3 standard an energy remuneration is awarded.
Auctions & Prices

Primary, secondary, and tertiary reserve are traded by the Belgian TSO Elia in auctions on the control reserve markets. Market participants submit initial bids for capacity price, which are sorted by amount in a merit-order list. For secondary and tertiary reserve, providers with winning bids take part in a second auction and submit bids for the unit price. If the control reserve is needed, providers with the lowest price receive the tender first. Higher bids then follow in order. If a control reserve order is placed, secondary and tertiary reserve providers are also paid the additional unit price. While FCR and aFRR are tendered on a weekly basis, mFRR is tendered on a monthly basis. In addition, Elia tenders part of its FCR power on the regional market regelleistung.net .
