Who we are

Stemy Energy

Stemy Energy was created with the mission to reduce the energy bill of end-users, reduce their carbon footprint, and promote a more sustainable energy system, using learning tools to participate in the ancillary services market in real time whilst managing the demand simultaneously.

Stemy Energy was founded by Alvaro, Jaime, Francisco, Miguel, Antonio and Carlos, experts with 20 years of experience working in high performance intelligence in the electricity sector. It was born from a project called SPLODER, which evolved into a commercial product as it proved successful. Stemy has worked with Spanish utilities, and has a working platform with homes all over Spain. Now, Stemy is creating new products adapted to the UK electric market and user experience.
