A young French start-up, eKwateur is renowned as a supplier of electricity and gas renewable independent and alternative in order to respect our environment. Their main challenge is to reconcile energy transition and savings.
SirEnergies explains everything to you in less than 3 minutes.
ekWateur was created in November 2015, and is a brand of the French energy supplier Joul.
During its existence, this French start-up has been able to make itself known thanks to its position as a supplier of 100% renewable energy, as well as to several awards.
In 2020, eKwateur raised funds allowing them to develop projects on solar self-consumption.
Since 2016, ekWateur has been offering renewable gas and electricity supply offers to private customers and small professionals.
Rare enough to highlight, eKwateur claims to be an energy supplier collaborative, that is, its consumers can become brand ambassadors, invest in society and share their experiences with future customers. A loyalty points system has been put in place to reward customers who collaborate the most.
In addition, eKwateur supports its customers towards self-production and the self-consumption of their energy, in particular produced by solar panels.
Finally, the start-up is the first energy supplier in the world to accept SolarCoins, the first digital currency for solar energy.
ekWateur supplies energy only to “small” individuals and professionals, i.e. with a meter power of less than 36 kVA.
This corresponds to the profiles” Blue rate ”, that is to say SMEs, traders, liberal professions, artisans, etc.
The electricity supplied comes from production hydraulics only (for now). In the long term, it will also come from wind turbines and photovoltaics.
All the company's offers are based on a personalized quote, by manually configuring your profile on the eKwateur website, or by telephone.
Future customers can subscribe to electricity offers at a fixed price or at an indexed price (variable).
The green gas supplied by ekWateur is biogas (or biomethane) resulting from the decomposition of organic matter. The quality and origin of gases are guaranteed by the Guarantees of Origin mechanism.
