Smart Energy-as-a-Service for SMEs — batteries + green power in harmony.

The Problem

Across Europe, businesses are increasingly squeezed by high electricity prices, extreme price volatility, rising grid fees, and expensive peak loads. This is especially painful for the German Mittelstand, which consumes more than half of the country’s electricity and is seeing energy costs turn into a direct competitiveness risk.At the same time, a major opportunity is emerging: new regulatory frameworks allow multi-use battery storage systems to be operated grid-fee-exempt when used in a grid-supportive way. This creates a pathway for companies to use flexibility economically — but until now, it has been difficult to access in a simple and reliable way.

The Solution

Einklang makes flexibility practical for commercial and industrial customers through an integrated system combining:

  • Battery storage
  • Einklang OS, an AI-powered software layer optimizing consumption, procurement, and storage
  • A flexible (dynamic) electricity tariff
The system automatically shifts electricity usage into the cheapest and most renewable hours, without requiring disruptive changes to existing operations. This reduces electricity costs, optimises the use of on-site PV generation, and provides a more stable and predictable energy supply.

Why we invested

Flexible energy systems behind-the-meter are becoming a central growth market of the energy transition. With the right regulatory tailwinds now in place, the ability to combine storage, software, and supply into one economic system is turning into a decisive competitive advantage for industrial and commercial customers.Einklang brings together deep energy expertise and strong execution experience, with founders who previously built and operated industrial storage and energy system platforms at Voltfang and Impuls. We believe the team, technology, and timing are exceptionally well aligned to shape this market at scale.
