How it works  

In the event of a sudden peak or drop in electricity demand, we will send you a message asking you to activate your flexible power capacity.

We can also install a Flexibox that will automatically activate the flexible capacity at your site and alert you.

NextFlex can also certify your flexible capacity and help you reduce your electricity bill during peak periods. With certification, you no longer have to reduce your consumption every time there is a peak demand; you only need to activate the flexible capacity when the electrical system requires it and you will be paid for it.

Benefit from the FlexiBox

We propose to automate the realization of your activations. For this, we have a hardware solution, the Flexibox, with which we communicate preferably via the GSM network or, via ADSL or internet. We install it on your site and connect it to your flexible equipment. It can also be connected to one of your PLCs or to a supervision system (e.g. a EMS). The Flexibox has two functions: to send orders to your flexible capacity and to retrieve information to control the correct execution of an activation (counting data, fault signal, etc.). The interest is to reduce the mobilization time of your capacity and/or to avoid human intervention. Do not hesitate to consult us on this subject.


    3 steps to enhance the value of your electrical erasures simply:

    1) Qualification :

    We determine the extent to which your site can adapt its electricity consumption or production to our demand, in order to react to activations. We identify together :

    • Your flexible equipment
    • The flexible  power of this equipment

    NextFlex tells you if your site is eligible for an offer for flexible capacity.


    2) Evaluation :

    We determine together :

    • The flexibility that you can provide
    • The technical solution to be implemented for activation

    NextFlex gives you the value of your flexible capacity.


    3) Realization :

    • We sign a flexibility contract, independent of your electricity supply contract.
    • NextFlex installs and test the  activation solution.

    NextFlex provides you with all the data you need to track your performance and quantify your revenues.
