One of the largest steel mills in the Dnipropetrovsk region has completed a comprehensive energy independence project. The plant has commissioned the largest rooftop solar power plant for an enterprise in Ukraine, with a capacity of 4 MW, integrated with an industrial energy storage system (BESS) with a capacity of 4.2 MWh. The project, implemented by Rayton, will allow the plant to save approximately $1.5 million annually.
As of April 1, 2026, the full cost of electricity for industry (voltage class 2) in the region is 9–10 UAH/kWh, and during peak evening hours on the day-ahead market (DAM) it reaches 12–15 UAH/kWh. With the plant’s monthly consumption of 400–500 MWh, electricity bills amounted to 4–5 million UAH. Additionally, sudden power outages threatened to shut down the electric arc furnaces, which meant tens of thousands of hryvnias in direct losses every hour and the risk of damaging expensive equipment.
“For modern industry, especially an energy-intensive sector like metallurgy, on-site power generation and industrial batteries are no longer just an environmental trend but a basic requirement for survival and competitiveness,” commented Olga Lesko, director and co-founder of Rayton. “This complex in Dnipro has become one of the largest hybrid projects for industry in Ukraine and the largest existing rooftop station in Ukraine for self-consumption on a ballast mounting system. “We have created a system that not only generates kilowatts but also intelligently manages the consumption of the entire plant, protecting it from blackouts and price shocks in the electricity market.”
How the plant’s smart energy system works
The solar power plant complex (4,027 kW) and the storage system (4,180 kWh) operate as a single unit, addressing three key tasks:
Economic impact: payback in 3 years
The total investment in the modern energy complex amounted to approximately $3.9 million, of which $3 million was allocated to the construction of a solar power plant (SPP), and another $900,000 to the integration of energy storage systems (ESS).
The projected annual generation of the SPP is 4 million kWh, which, at an average tariff of 8 UAH, will generate approximately 32 million UAH (over $727,000) in annual revenue, returning at least one-third of the invested funds annually. Although storage systems slightly increase the cost of a “solar” kilowatt-hour, their use allows for maximum efficiency and generates $1.5 million annually (total savings from the solar power plant and ESS combined — ed.).
“The economic model of the solar power plant shows a payback period of less than three years, which is an unprecedented figure demonstrating the extremely high profitability of such solutions,” adds Olga Lesko. “Over the projected 30-year operational life, the solar power plant and the industrial system will generate over 1.9 billion UAH in net profit for the plant.”

Approximately 270 hectares of low-quality state-owned land have been leased for the project, with a lease rate of €1,050 per hectare per year, of which 40% goes to the community budget and 60% to the republican budget.
Central Europe Energy Company is registered in Belgrade, with Qin Zhang listed as the responsible person, according to CompanyWall data.
PJSC Dnipro Metallurgical Plant (DMZ), part of businessman Oleksandr Yaroslavsky’s DCH Steel group, has completed its transition to continuous casting, DCH Steel CEO Vitaliy Bash announced in the corporate newspaper on Thursday.
“DMZ has implemented solutions to maintain competitiveness in difficult economic conditions. The transition of rolling production to continuously cast billets, which we purchase from partners, has been completed, allowing us to reduce the cost of metal production. DMZ has expanded its scope of activities by providing laboratory research, repair, and manufacturing services for metal structures and equipment parts, which is already yielding certain economic results,” the CEO noted.
According to him, in 2025, the Sukha Balka mine continued to develop new horizons and updated its equipment fleet to improve safety and production efficiency. An important step was the construction of a solar power plant, which ensured the energy independence of the Frunze mine.
At the same time, he pointed to negative trends in the market, in particular the increase in imports of metal products to Ukraine and the growth of tariffs for state monopolies.
“Together with other metallurgical companies and industry associations, we are systematically working to solve these problems at the state level. Despite all the challenges facing the industry and the country as a whole today, our teams continue to work, plan, and build the future,” said the CEO of DCH Steel.
DMZ specializes in the production of steel, cast iron, rolled products, and products made from them, such as channels and angles, special profiles for mechanical engineering and the mining industry.
On March 1, 2018, the DCH Group signed an agreement to purchase the Dniprovsky Metallurgical Plant.
The Sukha Balka mine is one of the leading enterprises in the mining industry in Ukraine. It extracts iron ore using underground methods. The mine includes the Yuvileina and Frunze mines.
The DCH Group acquired the mine from the Evraz Group in May 2017.
