Welcome to Stroomzaken

Who are we

STROOMZAKEN is a Dutch company that focuses on sustainable energy solutions, including battery energy storage systems (BESS), generator sets and hybrid energy systems.

We develop, supply and integrate complete energy supplies for both residential and industrial applications, with an emphasis on reliability, innovation and efficiency.

Through direct collaboration with manufacturers in China, Asia, the European Union, and the United Kingdom, we are involved in product development, quality control, and certification. We actively contribute ideas for technical improvements and innovations, issue targeted orders to our production partners, and are regularly present at the factories. This ensures our solutions meet the requirements and expectations of the European market.

The foundation of our company was laid in 1984 with the establishment of Technische Handelsonderneming Van den Heerik, specialising in wire processing and wiring harnesses. In the years that followed, broad experience was gained within the shipping, oil and energy market, and the world of power units and generator sets.

This background continues to form the core of our approach: practical, down-to-earth, and results-oriented. Technical knowledge, commercial insight, and a keen eye for quality and service are central to this.

Since 2019, we have been actively focused on the development and application of (industrial) battery storage systems (BESS). By 2025, we will have entered into collaborations with international manufacturers of battery storage and inverters. With this, we are combining our existing expertise with the latest technologies within the energy transition.

Our aim is to deliver reliable, smart, and scalable energy solutions, suited to today's practices and tomorrow's challenges.

Since 2006, our focus has been entirely on energy supply and sustainable technologies. From this experience, we build bridges between global producers and the European market.

Prime Power BV (2025) collaborates with international manufacturers and certified inspection companies, including Power Link Energy (partner since 2006) and various OEM suppliers. Together, we supply certified battery storage systems for the European energy transition.

In addition, we operate under the trade name STROOMZAKEN (2016). With this, we serve both the domestic market as well as SMEs and industry — always with one goal: making energy more accessible, smarter and more sustainable.

Our core values:

• Reliable and long-term partnerships.
• Technical depth and European certification.
• Honest and transparent communication.
• Innovation with an eye for people and the environment.
