Amsterdam, July 2, 2025 – Amsterdam-based climate tech company Dexter Energy has raised €23 million in a Series C funding round to further scale its AI-powered forecasting and trade optimization services for renewables and batteries. The round was led by Alantra’s energy transition fund, Klima, joined by Mirova and with continued support from existing investors, including ETF Partners, Newion, and PDENH.
Dexter’s mission is to accelerate the energy transition toward a fully carbon-free power system by making short-term power trading smarter, easier, and more profitable for renewable energy producers. Dexter’s intelligent software helps energy companies balance the electricity grid, reduce balancing costs, and optimize the use of solar, wind, and battery storage, crucial in an increasingly volatile energy market. With the investment, Dexter will expand its solutions for battery trading, boost its optimization tools for wind and solar energy, and grow into new European markets.
Luuk Veeken, CEO and founder of Dexter Energy, said:
“We’re excited to welcome Klima aboard. They share our belief that AI is now essential infrastructure for an electricity grid increasingly powered by renewables and storage. This investment enables us to grow our team, expand into new markets, and redefine short-term trading for wind, solar, and battery portfolios. In doing so, we can help more companies get the most out of their clean energy and support them in balancing the grid.”
Helping clean energy players thrive in Europe’s volatile power markets
As renewables rapidly scale across Europe – from around 34% of electricity generation in 2019 to 47% in 2024, and an expected 70% by 2030 – clean energy producers are facing growing challenges. They must compete in a fast-changing market where prices are volatile, weather drives constant fluctuations, and traditional subsidies are no longer the main source of income.
In the Netherlands, for example, renewable producers have seen their revenues drop by more than 30% since 2019, due to price declines caused by cannibalization and rising balancing costs resulting from forecasting inaccuracies.
Dexter’s technology helps energy producers extract more value from their renewable energy assets. It dynamically optimizes production across the day-ahead, intraday, and imbalance markets. By intelligently leveraging physical flexibility, such as temporarily curtailing production or controlling storage, Dexter’s software delivers automated trading strategies and real-time asset control. This enables energy companies to significantly increase their revenues.
With this new investment, Dexter will accelerate the development and rollout of its asset-backed trade optimization solutions for wind and solar across Europe. Dexter will also use the funding to fast-track the development and deployment of its solutions for battery trade optimization, initially in the Netherlands and then across key European markets.
Iñigo Echaniz, Partner at Alantra’s Energy Transition fund, Klima commented:
“Dexter Energy exemplifies the kind of cutting-edge energy tech we seek to invest in at Klima: solutions that combine advanced AI with deep energy market expertise to drive real impact. Their ability to optimize renewable and battery trading in and across multiple complex markets will be critical as Europe scales its clean energy infrastructure.”
Anne Boulet, Investment Director at Mirova, added:
“We are excited to partner with Dexter and join the journey with Klima and historic investors. We have been impressed by Dexter’s product and the team’s ability to scale in Europe. This strategic investment reinforces our commitment to advancing technology and energy solutions, while creating valuable synergies with our existing infrastructure portfolio.”
