Welcome

Willem-Bernard Investeringsmaatschappij B.V. is an independent Dutch investment company active since 2005. We develop, help realise and invest in wind and solar energy companies and projects, independently or in cooperation.

Our mission is to ‘build a sustainable environment’ by providing capital and knowledge, sharing our experience by potentially playing an active role as a shareholder and/or board member.

The focus of Willem-Bernard Investeringsmaatschappij B.V. is on renewable energy. All revenue and profit will be invested in new renewable and sustainable projects. Next to the expanding portfolio of wind, solar and BESS assets WBI is participating in starting or growing companies with innovative sustainable business models. In 2023 it invested in Move Energy Fund.

‘Long term value and revenue creation for all stakeholders’ is our goal.

Willem-Bernard Investeringsmaatschappij B.V. (WBI) has participations in operational wind energy parks in the Netherlands, Curaçao and Aruba with promising extension possibilities and has expanded its business in the solar PV sector through its subsidiary Sunwatt BV created in 2014.

In April 2014 Sunwatt acquired a majority shareholding in Solaris Real Ltd based the UK. Solaris operates a 300 kWp solar park since 2011 and has developed and realised an extension of 800 kWp. Sunwatt continues growing its business and portfolio of solar PV parks in the United Kingdom and the Netherlands. In 2025 Sunwat will add its first BESS asset to its portfolio.

In 2014 WBI has structured and successfully placed in the market an asset back bond (subordinated debt) for two operational solar PV parks in the east of Germany totalling 4,8 MWp. In 2020 the bonds have been bought back by the developer.

Sunwatt is since August 2016 the proud owner of Solarpark De Kwekerij, a 2 MWp solar park in Hengelo (GLD), Netherlands. The first park in the world which combines nature development, recreation, water retention and green electricity production. Sunwatt’s skills of financing, structuring, solar PV development and exploitation and ecological knowledge helped this project to realisation. Many thanks go out to all involved parties and the people of Hengelo who made this special park possible.

In the period 2016 to 2019 Sunwatt has helped with the structuring, financing and realisation of solarpark De Groene Weuste. This park has a capacity of 4 MWp and was development by Stichting Duurzame Energie Wierden-Enter (SWEDE). A real community project where the financial yield and social (labour) benefits were fully optimised for the people living in Wierden. In 2021 Sunwatt and SDEWE has successfully developed and realised an extension of 1,5 MWp called De Groene Weuste +.

Sunwatt won in the summer of 2017 with its partner HVC a tender called for by the municipality of Almere for a 34 MWp solar-PV project. This ‘state of the art’ east-west oriented solar park has been developed by HVC and Sunwatt to create huge financial and social benefits for the people and local companies of Almere. In July 2019 the park was successfully built. Together with De Groene Reus lucrative crowdfunding was deployed.

Since 2017 WBI has provided start capital to and as shareholder actively supported Yilkins Drying Solutions. Yilkins engineers, designs and builds high efficient industrial drying equipment and torrefaction machines for all kinds of biomass. Yilkins focus is helping their global clients implementing a circular approach by sourcing (low grade) biomass, drying it in the most cost effective and efficient way and reusing the upgraded biomass. After having sold and commercially successfully commissioned two drying and torrefaction projects the sales stalled during the global pandemic but engineering continued. 2023 marked an important step in the history of Yilkins by securing three equipment sales of Yilkins drying and torrefaction solutions with globally active industry leaders. Once these three projects are realised during 2025 they provide a huge upside potential.

Recently Sunwatt co-developed, structured, financed and realised a multifunctional floating solar park of 3,2 MWp in Boskoop. Part of this project has been the creation of a much needed water retention facility of 3,5 hectares for the tree nursery area of Boskoop. The project has been commissioned in October 2021 and has been called Zonnevijver Boskoop.

Currently Sunwatt is partnering with Insinco to develop, realise and exploit a 19 MWp solar project with large scale BESS deployment called Duurzaam Daslever. It is a large scale nature inclusive solar PV project of 13 hectare with around it 17 hectares of biological agriculture. So far it is the only solar project that has obtained the support of the local community.
