CHESM — EPC company with over 20 years of experience in the energy sector

CHESM is a Ukrainian EPC company that has specialized in the construction and operation of energy facilities since 2000, including solar, wind power plants, as well as energy storage systems. Our portfolio includes more than 400 successfully implemented projects both in Ukraine and abroad.

We operate under a vertically integrated business model that covers all stages of project implementation — from design and logistics to manufacturing, construction, testing, and commissioning. This approach enables us to make prompt decisions, quickly adapt to changes, and deliver maximum efficiency for our clients.

CHESM has unique experience in operating 330 kV substations, which confirms our expertise in high-voltage infrastructure and our ability to work with critical energy facilities.
