HYDROPTION background

Company founder

Michel de KéreverMichel de Keréver, ENSTA engineer, Master 2 La Sorbonne, optimized the production of players such as Poweo Direct Energie, RWE and EON with useful and complex financial products. He had long wanted to create his company by providing access to cutting-edge optimization techniques to smaller players in the electricity industry, producers and consumers.

« Restoring meaning to finance »

“Every year, French energy is a little more subject to the law of the market, and renewable energies are also approaching it after several years in the shadow of public subsidies. HYDROPTION wishes to make its expertise in market finance available to all players in the sector, whether consumers or producers.”

Translated passage from Anne-Claire Poirier’s article, journalist at GreenUniveres.

Our values


A company on a human scale, HYDROPTION attaches great importance to the proximity and satisfaction of its customers.


Banks, insurance, Internet, telephony,… we are nowadays invaded by a flow of information and documents. In order to avoid being added to this list, HYDROPTION is committed to being as simple and concise as possible, both in its commercial approach and in the management of customer relations.


Today, many renewable energy producers and electricity consumers are being neglected by current players who offer them standardised offers, without really caring about their needs. One of the main advantages of working with HYDROPTION is that you can benefit from personalized support, regardless of the size of your company.

Responsible commitment

By sourcing from renewable energy producers (mainly from hydro and wind power), HYDROPTION works for the energy transition and is thus committed to protecting our planet.
