FAQ

1-WHAT IS THE DIFFERENCE BETWEEN ELECTRICAL FLEXIBILITY AND DEMAND RESPONSE?

Electrical flexibility is the ability of a site to modify its consumption curve (upward and downward) at the request of a third party. When this change is to reduce the electricity consumption of the site, we talk about demand response . The demand response is flexibility in one direction.

2-WHAT IS DEMAND RESPONSE?

It is the reduction of the power consumption of your site, at the request of NextFlex .

3-WHAT IS LOAD SHEDDING?

It's stopping non- critical equipment. The shedding can be used in two conditions:

  1. During a power failure
  2. To not exceed the power subscribed to the network manager

4-WHAT IS THE PURPOSE OF DEMAND RESPONSE?

Demand response is most often used to meet an unexpected need of the National power grid :

5-WITH WHICH ELECTRICAL EQUIPMENT CAN YOU DO DEMAND RESPONSE?

If you haveit, and provided that it does not disturb the activity of your site :

  • Those who provide electrical relief for the site, for example:
    • Generator
    • Battery
  • Those that can be stopped or run at lower rpm for 30 min at 2h depending on the country, for example:
    • Cooling units
    • Ventilation plant of a building
    • Heating plant of a building
    • Pumping Group
    • Sewage plant Basin Aerator
    • Centrifuge
    • Liquid heating Resistance
    • Production line or workshop with buffer capacity

6-HOW TO MEASURE THE ERASED POWER?

The erased power is the difference between the reference power and the average of the powers consumed by the site over the period of demand response .

When the ability to demand response is valued with the network manager, the definition of the reference power is as follows:

Electrical flexibility load curve by NextFlex ENGIE

7-HOW IS THE DEMAND RESPONSE PAID?

The remuneration has two terms:

  1. A fixed availability premium, proportional to the erasable power you make available to NextFlex over the contractual period (in €/kW)
  2. A remuneration of the activation, proportional to the energy cleared (in €/kWh). The erased energy is the product of the power erased by the duration of the demand response . We agree together on the level of remuneration, which must have a minimum cover your activation costs

8-CAN ERASABLE EQUIPMENT BE UNAVAILABLE?

As part of your contract with NextFlex , you can declare any downtimeat any time. We define in the contract a maximum volume of unavailabilities and the premium of demand response is calculated accordingly.

In France, if you do not realize demand response While your equipment is declared available, a penalty is deducted from the premium of demand response . However, you do not take any financial risk to make available NextFlex your ability to demand response . In any event, you take no risk because the deduction will never exceed the fixed premium.

9-WHAT ARE THE TECHNICAL SOLUTIONS TO ACTIVATE FLEXIBLE ASSETS ?

Two technical solutions are possible.

The first is to send you an order of demand response by email, phone and SMS. You choose the recipients of the message. You activate the erasable equipment by yourself, within an agreed timeframe together

The second is to install at our expense a remote activation box of your equipment. NextFlex activates the flexible equipment, warning you a few minutes before by email, phone and SMS. You choose the recipients of the message. This makes it possible to offer you more value by reducing the activation time, and to avoid that you mobilize staff to perform the demand response. Our commitment is to activate your equipment only on the times we have agreed to, and to allow you to declare unavailability at any time.

10-DO I HAVE TO AGREE WITH MY ELECTRICITY SUPPLIER TO PARTICIPATE TO THE NEXTFLEX OFFER?

No, it is not necessary to have the agreement of the electricity supplier to do demand response with NextFlex. The grid operator proposes to value in the markets of electricity, the electricity reduction obtained by the demand response operator, without needing the consent of the site's electricity supplier. Thus, these rules allow the establishment of a fair playing field between the different players in the flexibility market, the suppliers, the demand response operators or the consumers on-line. This has no impact on the electricity contract of the electricity supplier. In case of doubt about the current contract, the NextFlex team can check with the client if it is eligible.

11-CAN I DO DEMAND RESPONSE REGARDLESS OF MY ELECTRICITY SUPPLIER?

yes NextFlex independently of the electricity supplier, whatever it is.
