1Komma5° Manages One Gigawatt of Flexibility

Why this is here: Heartbeat AI currently manages over 100,000 energy systems, allowing homeowners to shift consumption and potentially sell surplus power during peak times.

1Komma5° in Germany now manages one gigawatt of flexible energy sourced from private photovoltaic storage systems. The company connects residential solar installations, battery storage, heat pumps, and wallboxes to create a virtual power plant. This represents roughly one-eightieth of Germany’s peak energy demand, allowing 1Komma5° to optimize energy consumption and generation for its customers.

The company’s “Heartbeat AI” system currently controls over 100,000 systems, shifting energy usage to times of low cost or selling excess power during peak demand. 1Komma5° has opened its system to installers and manufacturers, moving beyond a closed ecosystem. Customers pay a fixed monthly fee for this optimization service.

While the system currently works with about five percent of existing solar installations—specifically those from Kostal—the company plans to scale to 20 gigawatts of controllable power by 2030. A key challenge remains the slow adoption of market communication by some grid operators, hindering direct energy sales. 1Komma5° advocates for ending feed-in tariffs and transitioning to a market-based pricing system, but acknowledges the need for solutions to address process costs.
