Flower Charges Ahead in Europe – Expands to Germany, Finland and the Netherlands

The Nordic market leader in battery storage optimization and trading, Flower, is continuing its exponential growth journey. By gaining elusive market access in three high-priority European countries, hence opening up for trading throughout the full energy market palette – including ancillary service markets and wholesale markets – the company takes a milestone leap forward in Europe’s energy sector.

“Our vision has been clear from the beginning: to become a leading force powering the energy system of tomorrow. Entering these markets is just another testament to how we realize this commitment, ensuring our service contributes to a flexible and stable grid while making way for affordable, stable and predictable electricity to European industries,” says John Diklev, founder and CEO of Flower.

Driving revenue across the border

As an approved trading actor in all three countries, Flower has begun rolling out its advanced trading algorithms in the respective energy markets, successfully driving revenue for its partners. 

“It’s exciting to see our AI-driven optimization now entering these more dynamic European markets. By jointly optimizing assets such as batteries, wind and demand response — using machine-learning models that account for weather forecasts, grid conditions, market signals and parameters like battery duration, tariffs and warranties — we can increase revenues and reduce risk at the portfolio level, a concept we’ve already proven in Sweden. These more liquid and volatile markets offer strong potential to capture more value from flexibility while strengthening the grid,” says David Elez Berselius, VP of Product at Flower.

A fast-growing pan-European battery storage pipeline

In addition to energy trading, Flower is in the process of heading up a large pipeline of battery energy storage projects across Europe, all developed with in-house expertise. Large-scale projects are now being contracted in Germany, the Netherlands, France, and Belgium – all adding up to a profound multi-GWh pipeline. 

“Energy storage is such an instrumental component of the energy transition. With our deep knowledge of the energy market we are uniquely equipped to speed up the build of this crucial energy infrastructure while making sure it generates the most value. Combined with our market-leading expertise in trading and optimization we are in a strong position to accelerate the pace of Europe’s energy transition,” says John Diklev, founder and CEO of Flower.

The complex road to market access

In order to optimize and trade with energy assets in the highly regulated energy markets of Finland, Germany and the Netherlands, energy actors are required to go through the process of becoming a Balance Responsible Party (BRP). This means they have the responsibility to control supply and demand in the energy system while being accountable for potential imbalances. The BRP application is highly meticulous and thorough, since the role involves handling critical and sensitive infrastructure. Ultimately, the approval is confirmed by the Transmission System Operators (TSO) in the respective countries. 

Since 2024, Flower has been an approved BRP in Sweden. Throughout 2025, Flower has been approved by the TSOs Amprion and 50 Hertz (Germany), Tennet (Netherlands) and Fingrid (Finland).
