Vattenfall Selects Kraken Technology Platform to Scale its Battery and Renewable Energy Portfolio in Germany

• Kraken's platform will provide a common cloud-native layer to manage and control standalone batteries, wind, solar and co-located assets — spanning nearly every configuration in Vattenfall's German fleet
• The partnership will connect Vattenfall's trading operations directly with its diverse portfolio of physical assets, enabling new market participation
• Kraken brings proven experience in controlling over 4GW of grid-scale batteries and complex co-located sites at scale in multiple EU markets

Berlin/Hamburg/London, 10 November 2026 – Vattenfall has selected Kraken, the end-to-end operating system for utilities, as its technology platform for managing grid-scale battery storage and renewable energy assets in Germany.

Kraken’s platform will provide a cloud-native control layer across Vattenfall’s standalone battery energy storage systems (BESS), wind and solar generation, and co-located assets enabling Vattenfall to operate these assets as a virtual power plant. Co-location – combining battery storage and renewable generation behind a single grid connection – is a growing share of Vattenfall's German portfolio, and one of the more complex asset configurations for utilities to manage at scale. Managing it well means Vattenfall can capture value from both the battery and the renewable asset simultaneously, rather than trading off one against the other.

Building on its experience controlling over 4 GW of grid-scale batteries and co-located sites across Europe, Kraken will partner with Vattenfall's ambition as leading offtaker and solution provider for battery storage and co-located renewable assets – unlocking greater flexibility and value across Germany aiming for a multi GW portfolio together.

The partnership will connect Vattenfall's trading operations directly with its physical assets, translating commercial decisions into secure, real-time action and allowing renewable energy systems and BESS to continuously participate in ancillary services and wholesale trading. This reduces imbalance exposure and helps capture more value from volatile markets, improving returns across the portfolio. Vattenfall will trade the portfolio; Kraken will provide the critical technology infrastructure that sits between decision and delivery. Together, these capabilities will allow Vattenfall to manage and scale a diverse portfolio as a VPP rapidly, while avoiding fragmented systems.

Christian Sdralek, Director Portfolio Management in Vattenfall’s Trading Unit, said: “The market for battery storage and co-located renewable assets is growing rapidly. We see significant opportunities to help asset owners maximize the value of their flexibility while supporting the integration of renewables into the energy system. Through our partnership with Kraken, we are strengthening our ability to offer innovative offtake and optimization solutions at scale across Germany and Europe.”

Charlotte Johnson, General Manager, Flexibility at Kraken, said: “Utilities across Europe are investing heavily in battery storage and renewable generation, but scaling these portfolios requires more than adding new assets. It requires a technology foundation capable of connecting and coordinating different assets as one portfolio.”

Johnson added, “Kraken will give Vattenfall a common platform from its trading desk to its physical assets. Our experience in grid-scale batteries and co-located sites means Kraken can manage the complexity beneath the surface, allowing Vattenfall to focus on growing its portfolio and capturing its full potential.”
