DTEK, together with the American company Fluence, has built a 200 MW energy storage facility (ESF), which is currently the largest such complex in Ukraine, the energy holding company reported.
“The DTEK Group has commissioned 200 MW of ESS facilities, created in partnership with the leading American company Fluence, a global leader in energy storage. The company has connected six new facilities of various capacities, ranging from 20 to 50 MW, to the power grid in the Kyiv and Dnipropetrovsk regions,” DTEK said in a press release on Thursday.
According to the release, DTEK’s investment in the construction of the complex, which lasted from March to August 2025, amounted to EUR125 million, and in total, the system will be able to store 400 MW*h of electricity, which is enough to supply 600,000 Ukrainian homes for two hours.
“In the context of massive attacks on the Ukrainian power system, the role of energy storage systems has become as fundamental as generation itself. The National Renewable Energy Action Plan until 2030, adopted by the government, clearly defines the need for such installations, and today we are seeing strategic goals being implemented. I am grateful to the DTEK Group for its proactivity in this matter and to our American partners at Fluence for their advanced technologies, thanks to which each new megawatt of storage acts as a shield for the entire power system. This means greater security for Ukrainians and fewer risks of emergency blackouts,” commented Ukrainian Energy Minister Svitlana Grinchuk.
DTEK CEO Maxim Timchenko called the launch of the UZE complex a historic step for the Ukrainian power grid, which will determine its development for years to come.
“We implemented it together with Fluence, a global leader in energy storage. In cooperation with our American partners, we are integrating the most advanced technologies to make Ukraine’s power system more reliable and resilient,” he said.
According to Fluence CEO Julian Nebreza, this is a joint contribution to creating a stronger, more resilient, and decentralized energy system that will ensure Ukraine’s long-term stability.
“We are honored to be working with DTEK on this landmark energy storage project. The extraordinary determination and efficiency that DTEK has demonstrated in implementing this project is truly inspiring. This achievement is a testament to resilience and a symbol of what can be achieved through close international cooperation. Even in these extremely challenging times, innovation and partnership can pave the way to greater energy security,” Nebreda emphasized.
As reported, DTEK and Fluence announced their intention to implement a project for modern energy storage systems (ESS, energy storage, energy storage facilities) in Ukraine with a capacity of 200 MW and a cost of EUR140 million in January 2025. It involved six energy storage facilities.
In June 2025, the DTEK energy holding received a EUR67 million loan from a consortium of Ukrainian banks consisting of Oschadbank, PUMB, and Ukrgasbank (UGB) for the construction of an 180 MW ESS.
At the time, the energy holding company noted that this was the first loan of this scale in Ukraine for the development of energy storage technologies, and the project itself was one of the largest in Eastern Europe.
DTEK won a special auction held by NPC Ukrenergo for the provision of automatic frequency restoration reserve (AFRR) services with 140 MW of UZE. Under the terms of the auction, NEC will purchase these services at the auction price for five years, starting October 1, 2025.
Fluence, headquartered in Washington, was founded in 2018 by Siemens and AES Corporation. The company has built approximately 35 GWh of energy storage capacity and approximately 30 GW of renewable energy sources.
Fluence has significant experience in integrating energy storage facilities into national energy infrastructures, with a portfolio of energy storage projects with a capacity of 201 MW in Lithuania and 450 MW in Germany.
DTEK was established in 2005 to manage the energy assets of Rinat Akhmetov’s System Capital Management (SCM, Donetsk) group. The corporation has been delegated the functions of strategic management of the group’s enterprises, which have formed a vertically integrated chain of coal mining and enrichment, electricity production and sales.
DTEK Energy’s machine builders have overhauled the EL160LS roadheader for the first time and handed it over to DTEK Shakhtoupravlenie Dniprovske, reports Corum Group.
“This is a new type of equipment for us, so the project was a real challenge. However, everything was completed on time and in accordance with the technical requirements,” the company said on its Facebook page.
According to the report, the machine received new explosion-proof electrical equipment of its own design, certified according to Ukrainian standards.
The machine has a 300-liter bucket and a 55 kW engine. It weighs 9.5 tons, has a boom swing of ±30°, and operates on slopes of up to 22°.
According to open source information, the EL160LS soil scraper is manufactured by the German company Hazemag. It is designed to level the soil of a mine workings, as well as to load loosened rock mass onto a belt or scraper conveyor.
Corum Group is a leading manufacturer of mining equipment in Ukraine and a part of DTEK Energy, an operating company responsible for coal mining and electricity generation within Rinat Akhmetov’s DTEK energy holding. DTEK Energy’s machine-building assets include Druzhkovka Machine-Building Plant (relocated to Dnipro), Kharkiv-based Svet Shakhtyora Plant and Pershotravensk Machine-Building Plant.
“Corum Druzhkovka Machine-Building Plant (Corum DrMZ), a part of Corum Group (DTEK Energy), has delivered an MBL belt reloader to Dniprovska mine (DTEK Pavlohradvuhillya), the plant reported on Facebook.
The reloader is the eighth since the beginning of the development of this area (at the end of 2024).
The MBL-007 delivered to the mine is a monorail reloader with a wheel, equipped with a belt 800 mm wide and 40 m long. Its main task is to continuously transfer rock mass from mining equipment to transportation vehicles, i.e., it is actually a link between mining and delivery: the reloader ensures fast and safe loading of trolleys or conveyors right in the mine.
The cost of the equipment was not disclosed.
“Corum DrMZ, relocated from Druzhkivka (Donetsk region) to Dnipro in 2022, manufactured 142 units of mining equipment in January-May this year, repaired three shearers, produced 344 metal structures and more than 362 thousand components and spare parts.
According to the Clarity Project, in the first quarter of this year, the plant reduced its net income by 36% to UAH 215.3 million.
Corum Group is a leading manufacturer of mining equipment in Ukraine. It is a part of DTEK Energy, an operating company responsible for coal mining and coal-fired power generation within Rinat Akhmetov’s DTEK energy holding.
Since the beginning of 2025, PJSC DTEK Kyiv Electric Grids has replaced almost 19,000 outdated meters with new smart meters in homes in the capital.
“The energy company is doing this at no additional cost as part of an investment program approved by the state regulator NEURC,” the company said on its website.
The company called the replacement of meters an important step in the large-scale digital transformation of Kyiv’s distribution network—customers will receive accurate electricity bills without having to submit their meter readings every month, and energy companies will be able to manage their networks more efficiently by analyzing the data received.
“Smart meters are a basic element of a modern technological network, allowing it to independently adapt to changes in demand and equipment status,” DTEK Kyiv Electric Grids said.
As explained by the company, a smart meter automatically records electricity consumption readings and transmits them to DTEK Kyiv Electric Grids in real time. This provides an accurate picture of consumption every hour, not only for individual apartments or houses, but also for entire neighborhoods and streets. At the same time, all information from the meters is aggregated and analyzed, which allows identifying peak periods and optimizing equipment operation, as well as forecasting consumption for early reinforcement of network sections.
The smart meter also allows remote diagnostics of the device status. In particular, distribution system operators can detect technical failures or damage without visiting the home or business, which significantly reduces response time.
Data from meters can be integrated with the SCADA energy infrastructure monitoring and remote control system. This allows dispatchers to see the actual consumption picture at all points of the network, automatically locate faults, and avoid emergency shutdowns.
DTEK Kyiv Electric Grids emphasized that the transition to the latest electricity metering devices is an important part of the “Network of the Future” infrastructure modernization project. It is planned that by 2034, all residents of Kyiv will have a smart meter in their homes.
“As of May 20, we have installed 18,969 smart meters for Kyiv residents, and in 2025 we plan to replace almost 47,000 old devices with new ones. Currently, 41% of customers in the capital have smart electricity meters,” said Denis Bondar, CEO of DTEK Kyiv Electric Grids.
Kyiv residents can find out whether their meters are scheduled to be replaced this year on the DTEK Kyiv Electric Grids website. The company explained that smart meters are primarily installed in buildings where the existing meters are reaching the end of their service life.
According to OpenDataBot’s ranking of Ukraine’s largest employers by region, based on companies’ financial reports for 2023, DTEK Odessa Power Grids has become the largest employer in the Odessa region, providing jobs for more than 3,000 employees. The company specializes in the transmission and distribution of electricity and is part of the DTEK energy group owned by businessman Rinat Akhmetov (SKM group).
According to State Statistics Service and open sources:
Number of employees: about 3,200 (as of the end of 2023)
Revenue: UAH 6.9 billion (2023)
According to public statements, the company is investing in the modernization of power grids and the digitization of services. In 2023 alone, more than UAH 700 million was allocated to infrastructure upgrades and improving the reliability of power supply.
In January-April 2025, DTEK Energy allocated approximately UAH 1.6 billion to repair and restore thermal power plants damaged by massive enemy shelling.
According to a press release from the energy holding company, the repair campaign is currently continuing without interruption, as the scale of the damage remains critical. A year ago, 90% of DTEK Energy’s generating capacity was destroyed or seriously damaged by attacks. On the eve of last winter, energy companies managed to restore more than half of it, but new strikes in November-December again caused serious damage.
“Our main task is not to stop. We are working every day on restoration to ensure the stable operation of the power system in the summer, during peak loads, and to confidently enter the next heating season,” said DTEK Energy CEO Alexander Fomenko.
In 2024, DTEK invested UAH 3.6 billion in the restoration of thermal power plants and another UAH 7.5 billion in the development of domestic coal mining.
Over the past year, Russia has carried out 13 massive attacks on Ukraine’s energy sector, dealing a serious blow to DTEK Energy’s thermal power plants, among others. In total, since the start of the full-scale invasion, the company’s thermal power plants have been attacked by the enemy 205 times. Fifty-six power plant workers were wounded in the attacks and four were killed.
DTEK Energy provides a closed cycle of electricity production from coal. As of January 2022, the company’s installed thermal generation capacity was 13.3 GW. A complete production cycle has been established in coal mining: coal extraction and enrichment, machine building, and maintenance of mining equipment.
