Blymyer completes preliminary design for major Ukraine BESS/PV project
Blymyer Engineers has completed feasibility study and preliminary design work for a high-profile, large capacity battery energy storage system (BESS) and photovoltaic (PV) initiative in Ukraine funded by a grant from the World Bank. The project will support energy infrastructure in the country, in conjunction with Ukraine’s main hydropower generation company, Ukrhydrenergo—one of Ukraine’s primary suppliers of energy.
Power generation is key for maintaining the stability of the power grid during emergencies in Ukraine. It also plays a crucial role in balancing the energy system, which is essential to support the operations of the intermittent renewable energy generators. This is the infrastructure that’s required to maintain the country’s energy security as well as gradually achieve Ukraine’s carbon neutrality goal.
The initiative includes installing battery energy storage systems (BESS) and solar photovoltaic (PV) plants at four different locations. This project aims to enhance the flexibility of the Ukrainian power grid through storage investments and market expansion to support synchronization with the European electricity grid and decarbonization of the power sector.
The World Bank’s Rapid Damage and Needs Assessment puts the total cost of Ukraine’s energy-sector recovery needs at $67.78 billion and its damages at $20.51 billion. As of Fall 2025, Ukraine’s energy infrastructure is operating at only about one third of its pre-invasion generation capacity. “[Energy infrastructure] is one of the most critical areas where Ukraine needs urgent support,” says World Bank Managing Director of Operations Anna Bjerde. “We are grateful for strong partnership with Ukraine and development partners to support this critical sector and act fast.”
Ukraine has established a goal of reaching 27% of its total energy consumption from renewables by 2035. Its current share of energy generated from renewable energy sources (wind, solar, biomass, biogas, and hydropower) is still comparatively small, at roughly 10%. Ukraine installed around 1.5GW of solar power in 2025, according to estimates from the Solar Energy Association of Ukraine (SEAU).
Expanding our international footprint
With over 80 engineers on staff, Blymyer Engineers is a global firm with offices in Europe and in the United States. “We are proud to be selected for this project in Ukraine,” says Greg Mazur, Blymyer’s Director of Engineering. “This BESS and PV initiative and others like it will be an important step forward in helping the country meet its renewable energy objectives.”
Experienced in all levels of BESS design, Blymyer’s engineering team excels at both custom solutions and connecting multiple large-scale rechargeable lithium-ion battery stationary energy storage units—responding to project, site, and client requirements, regardless of their scope or demands. To date, the firm has completed design for energy storage projects with a total capacity of 11,630MWh. Blymyer has also engineered hundreds of utility-scale and distributed-generation photovoltaic plants, totaling over 25GW in solar capacity.
“We remain committed to extending our company footprint beyond the U.S. as the demand for our BESS and PV expertise and full service capabilities—and our reputation for exceptional service—grows,” says Mazur. “The push for renewable energy is a worldwide priority and we are pleased to be considered a key partner in realizing the vast potential it holds for Ukraine and other nations around the globe.”
