Marble Invest is a continuously developing, Estonian based, private fund focusing on technologies, products and services related to renewable energy.
Our essence is to observe, realize, invest in and develop renewable energy systems (RES). Our purpose is to offer a close, hands-on management in our project companies.



The beginning of Marble Invest is closely related to Nelja Energia AS, the major renewable energy developer and operator in the Baltics, and its circle of investors.

The fund and its activities were launched in August 2011. Shortly after that, first capital operations were made, and the company has made investments and steadily grown its capital ever since.

The current key investors are Vardar AS, a Norwegian utility company owned by the Buskerud Fylkeskommune and its municipalities, and several private investors including prominent Estonian business leaders such as Hannes Tamjärv (HTB Investeeringute OÜ), Aivar Berzin (Vestman Energia AS), Peeter Mänd (Ivard OÜ) and others.
