Documents and forms

What is the difference with a fixed rate?

With a fixed tariff, the price of energy is constant over a defined period. This type of pricing is simple and predictable. With dynamic pricing, the price varies based on demand and market prices. This allows you to adapt your consumption to maximize use when prices are most advantageous.

What does a negative price mean and what does it imply?

A negative price means that the price per kWh is less than €0. The amount is therefore in your favor. This can happen but is still rare.

Can I switch to another product after subscribing to dynamic naturstroum?

Yes, it is possible to make the switch to naturstroum twice in 12 months.

Do I need to change my meter?

No, you keep your smart meter.

When can I subscribe to dynamic naturstroum?

You can subscribe to dynamic pricing at any time. To do this, contact our serviceline, and an agent will take care of sending you your contract. The dynamic naturstroum supply will begin on the 1st of the month following the signing of your contract.

Please note: The process of changing supplier may impact the date of the first supply in dynamic naturstroum.

Does dynamic pricing also exist for gas?

No, this pricing model only exists for electricity.

What happens if I am a self-consumer?

As a self-consumer, you have access to the dynamic rate under the same conditions as a grid-consumer customer.

Why is the professional tariff applied to “common” household usage?

“Common” residential consumption cannot be predicted – for example, lifts, lighting of corridors and cellars, which are activated at random at any time of day. This produces a higher purchase price, and thus a more expensive sales tariff.

The public lighting system is not working. Whom should I contact?

Public lighting of byroads is the responsibility of the administration of the local commune.The lighting of the State roads system is the responsibility of the Roads and Bridges Public Lighting Service (Eclairage Public de l’Administration des Ponts et Chaussées). If you wish to report malfunctions in the public lighting system, contact the administration of the local commune, which will pass on your complaint to the proper service.

What does the fee for metering and billing include?

Metering and billing, which is broken down on your statement, are invoiced to you monthly for a single or dual tariff meter recording a 24h/24h electricity supply. The dual tariff meter records the daytime period (06:00 to 22:00) and the night period (22:00 to 06:00). Meters form part of the network, and their price is defined by the network manager. Metering and billing consists of the following services: monthly rental of the meter, management of meter data, annual reading of the meter by a Creos Luxembourg S.A. official and management and dispatch of bills for the network manager.

What are single tariffs and dual tariffs?

Single tariff means the price of energy remains the same throughout the day, 24 hours a day, 7 days a week.

For the dual tariff:

  • a price of energy during the daytime (06:00 to 22:00) slightly higher than the single tariff,
  • and a lower price at night (22:00 to 06:00) will be billed.

This tariff mainly targets users of accumulation heating, electric water heaters or any other electrical appliance which is preferably used at night.

For both the single and dual tariffs, a monthly fixed premium in € is added to the energy prices expressed in c€/kWh.

What should I do in the event of an electrical power outage or a breakdown?

First, ensure that the outage has not been caused by a problem in your domestic wiring system, e.g., a fuse or a tripped differential circuit-breaker.

Then attempt to ascertain if the breakdown has affected several rooms. If this is the case, use the free phone number 8002-9900.

The network manager will send a unit to fix the power outage as soon as possible.
