Solar Wheel OÜ and Diotech Electric OÜ construct most of Enefit Green’s solar plants in 2020

Enefit Green AS, the daughter company of Eesti Energia AS, held a public procurement to find a framework partner for constructing solar plants until the end of 2020. We are honored to announce that despite strong competition, the joint offer issued by Diotech OÜ’s daughter companies Solar Wheel OÜ and Diotech Electric OÜ, was selected as the winning offer.

Becoming selected as the framework partner is simultaneously a great privilege as well as responsibility. We are grateful for the trust of Enefit Green AS and its team. Our team will be dedicated for carrying out the solar plant construction works with maximum possible quality to ensure that the installations are operating in accordance to all relevant requirements throughout the entire life cycle.
