Our team is set up by entrepreneurs who have experience in running and developing companies in the energy and construction industry. Industry-leading companies creating their own markets. Companies with a turnover of 10-20M€. The company’s owners have financed the product development. With over 10 years of experience in grid-connected battery storage and flexibility markets with support services, as well as developing products with intellectual property protection, we feel confident in the company’s current position and see a bright future ahead.

The Grensle team also includes development engineers, electrical engineers, patent engineers, mathematicians and universities that have been involved in our development over the past 10 years. The product development has taken place in both the Czech Republic and Sweden with pilot plants and prototypes in both countries. The development team is used to working on projects internationally. The biggest pilot plant built so far is located in Northern Sweden and has been in operation since 2024, a great success and our proof of concept.
