Symphonics offers its services free of charge because we are compensated by RTE, the electricity transmission network operator. Symphonics is remunerated for its participation in RTE's calls for the security and maintenance of the electrical grid balance. During consumption peaks, the electrical system can either trigger expensive and carbon-intensive electricity production or call on flexibility aggregators – which we are – who have the capacity to shift the electrical consumption of their client portfolio.
The service is fully automated and requires no action on your part.
The optimized programming is sent directly to your equipment, but you retain the ability to modify our suggestion. All you have to do is see the savings on your bill. Once this program is established: we take care of everything!
Savings and electricity contract
Our optimized and personalized programs, based on your consumption profile, automatically shift certain consumption to off-peak hours. Since the latter are generally 30% cheaper than peak hours: you will save with every kWh shifted!
It all depends on your consumption. However, our clients typically shift an average of 10% of the consumption initially planned for peak hours to off-peak hours. For a 150m2 house heated with electricity, this represents a saving of approximately €108 per year on average.
No, the service works regardless of your supplier, without any action on your part or ours.
Consult your electricity contract or your Symphonics application.
If you have opted for the peak/off-peak (HP/HC) tariff option with your electricity supplier, you benefit from a total of 8 off-peak hours.
These 8 hours are generally spread over one or two time slots. They are determined by the Distribution Network Operator (generally ENEDIS) according to local network constraints and vary depending on your place of residence. The times at which your peak and off-peak hours start and end are indicated in your electricity contract, generally with your consumption ratio for each time slot. This information will be updated directly in theSymphonics application in the event of any changes.
Yes. This does not prevent you from benefiting from the service, reducing your emissions and making a solidarity-based contribution to the good of the grid! Furthermore, if you wish to change your electricity tariffs, simply contact your energy supplier to switch to peak/off-peak hours.
The two services are compatible and complementary.
Your energy manager – a device for optimizing energy consumption – does not interpret your supplier's tariffs in order to adapt your heating. Similarly, your energy manager does not take into account the impact of the weather on temperature variations in your home. All these services are integrated into our services.
Equipment
Symphonics works directly with the manufacturers, so we know which equipment is compatible and which is not. What's more, Symphonics' services use the manufacturers' software and interfaces. Because we don't add a layer of hardware or technology, we can't alter the way your equipment works.
Contact your manufacturer. Symphonics services use the manufacturers' software and interfaces. As we do not add an extra layer of hardware or technology, we cannot alter the operation of your equipment. Therefore, in the event of equipment failure, you should contact the manufacturer or installer of your equipment, whose contact details are on the quote you received during installation.
If you have a Linky meter (ENEDIS network) and at least one connected device in your home, you should be eligible. Contact us on moiaussijenprofite@symphonics.fr to confirm your eligibility.

Environment
This service contributes to grid balance and is environmentally friendly. Indeed, electricity produced during off-peak hours is much less carbon-intensive than that produced during peak hours. You are therefore making a concrete gesture for the planet!
During peak consumption periods, the electrical system triggers carbon-intensive electricity production (gas or oil-fired power plants). With Symphonics, you avoid starting up these polluting production methods and thus participate in a less carbon-intensive electricity mix.
Also, be aware that Symphonics is careful to select partners and subcontractors who contractually commit to reducing their environmental footprint.
