Dexter Energy, an Amsterdam-based climate tech firm, has raised €23 million in a Series C funding round to scale its AI-powered forecasting and trade optimization services for renewable energy and battery storage. The round was led by Alantra’s energy transition fund, Klima, with participation from Mirova, and continued support from ETF Partners, Newion, and PDENH.
Dexter’s core mission is to accelerate the energy transition toward a fully carbon-free power system by making short-term power trading more intelligent and profitable. Its proprietary AI software helps energy companies balance the electricity grid, reduce balancing costs, and optimize the performance of wind, solar, and battery assets in real-time.
“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,” said Luuk Veeken, CEO and founder of Dexter Energy. “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.”
As Europe’s renewable electricity share rises — from 34% in 2019 to 47% in 2024, and projected to reach 70% by 2030 — clean energy producers must navigate a fast-changing market marked by price volatility and reduced subsidies. In the Netherlands alone, revenues for renewable producers have fallen over 30% since 2019 due to price cannibalization and rising balancing costs driven by forecasting inaccuracies.
Dexter’s platform addresses these challenges by enabling producers to dynamically optimize production and trading strategies across day-ahead, intraday, and imbalance markets. It also leverages physical flexibility — such as curtailing production or adjusting battery storage — to deliver automated trading and real-time control, significantly boosting profitability for asset owners.

With the fresh capital, Dexter plans to scale its asset-backed optimization solutions for solar and wind, enhance its battery trading software, and expand from its home market in the Netherlands into key European markets.
“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,” said Iñigo Echaniz, Partner at Alantra’s Energy Transition fund, Klima. “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.”
