At 1KOMMA5°, we pursue a clear vision: Living on wind and sunlight forever for free To make this a reality, we are building the energy system of the future with Heartbeat AI. Want to be part of it?We bring together regional craftsmanship and scalable software: We don't think of solar, batteries, heat pumps, and e-mobility as isolated components, but control them as an intelligent, integrated overall system in our virtual power plant. Directly connected to the electricity market – in real time, fully automated. This way, energy is used when it is available from renewables and particularly cost-effective. By 2030, our goal is to transition 1.5 million households to renewable energies. Over 3,000 people are working towards this every day, at more than 80 locations worldwide, from Finland to Australia.
Want to take responsibility and build solutions that truly matter? Apply now and help us shape the energy world of tomorrow.

1KOMMA5° wurde im Juli 2021 mit dem Ziel gegründet alle Gebäude zu elektrifizieren und CO2-neutral zu machen. Durch den Einsatz von Solaranlagen, Stromspeicher, Wärmepumpe, Klimaanlagen und Ladeinfrastruktur in Verbindung mit einer intelligenten Steuerung wird Wind- und Sonnenstrom automatisch dann genutzt wenn er günstig ist und am Markt verkauft wenn er teuer ist.
Das technologische Herzstück ist “Heartbeat AI”. Die KI-Software verbindet die Energiesysteme direkt mit der Strombörse und steuert jedes einzelne System nach individuellen Fahrplänen in Echtzeit. So wird immer der günstigste und sauberste Strom bereitgestellt, ob vom eigenen Dach oder vom Strommarkt.
Inzwischen steuert Heartbeat AI ca. 50.000 Energiesysteme und so über 450 Megawatt - das größte virtuelle Kraftwerke für Privatkunden in Europa mit einem Strompreis unter 10 Cent je kWh im Jahresdurchschnitt.
1KOMMA5° hat bereits über 120.000 Kunden und gilt laut EUPD Studie seit 2024 als europäischer Marktführer. Zurzeit betreibt 1KOMMA5° über 80 Standorte mit rund 2.500 Mitarbeitenden in sieben Ländern in Europa und Australien.
