History of Zakhidenergo
Zakhidenergo has a rich history that spans several decades. The company was formed in 1995, on the basis of thermal power plants BEO "Lvivenergo" – Burshtyn and Dobrotvirska TES, as well as Ladyzhyn TES.
The construction of Dobrotvirska TES began in 1951 and continued until 1959, with the installation of power units with capacities of 25 MW, 50 MW, 100 MW, and two 150 MW units. This marked the beginning of large-scale development of electric power in Western Ukraine.
The main direction of development for Zakhidenergo was to increase the unit capacity and improve the efficiency of equipment. To achieve this, the company focused on modernizing its power plants.
In 1962-1969, Burshtyn TES was put into operation, with 200 MW power units. This was followed by the construction of the Rivne NPP, the first nuclear power plant in the former USSR, which was introduced in December 1979.
Here are the connections of the Burshtyn TPP:
In 1996, the Burshtyn TPP was renamed from Burshtyn GRES, and in 2011, Zakhidenergo Open Joint-Stock Company was renamed Zakhidenergo Public Joint-Stock Company.

Project Overview
Zakhidenergo's reconstruction project was a massive undertaking that took only 10 months to complete. The project involved the reconstruction of electrical equipment of power unit No. 5 of DTEK Burshtyn CHP.
The scope of work was extensive, with over 10 different tasks performed, including the repair of synchronous electrical motors, replacement of high-voltage and low-voltage electric motors, and reconstruction of the integrated cable system. The project also involved the replacement of outdated equipment with modern ones, such as vacuum switches and current transformers.
Here are some of the key tasks performed during the project:
- Repair of synchronous electrical motors of ball tube mills (КВМ type)
- Replacement of high-voltage and low-voltage electric motors of main and auxiliary technological equipment
- Reconstruction of the integrated cable system and the lighting system of the power unit
- Replacement of air circuit breakers, current transformers, busbar supports, and installation of excess-voltage suppressors at the transformer annex

Environmental Impact
The Dobrotvir power station, operated by Zakhidenergo, has a significant environmental impact in Lviv Oblast. In 2020, it was named the top polluting enterprise in the region.
The power station has a history of releasing heated water into the Western Bug River, causing mass die-offs of fish in both 2020 and 2021. This has a devastating effect on the local ecosystem.
Flue gas stacks from the power station are a major contributor to air pollution in the area. The types of flue gas stacks include coal-fired, natural gas-fired, oil-fired, and those built in the Soviet Union.
The power station's environmental impact is not limited to air pollution. Leaking toxic chemicals into the Western Bug River has also been a significant issue.

Centrenergo Posts Strong 3Q11 Results
Centrenergo posted strong 3Q11 results, with revenues up 33% year-over-year to USD 251.6 million.
Its EBITDA margin increased to 20%, a 14 percentage point improvement from the same period last year.
A one-off tax benefit of USD 18 million contributed to Centrenergo's spike in EBITDA margin to 20% in 3Q11, which is 7% of 3Q11 sales.
The growth in coal prices, a key cost component, was limited to only one month of operations in 3Q11, as it increased by approximately 7% in September.
As a result, Centrenergo's strong profitability figures in 3Q11 have led to an increase in forecasts of GenCos EBITDA margins in 2011E by 1.5x-2x.

War in Ukraine
The war in Ukraine has taken a significant toll on the country's infrastructure, including the power plants managed by Zakhidenergo. In February 2023, the residents of Dobrotvir were left without electricity and heat due to damage to a critical infrastructure object.
Damage to the 150MW unit at the plant, known as Unit 7, was reported as of November 2023, with critical damage sustained. The plant was under attack by Russian missiles in May 2024, but it appeared to be operating in some capacity by June 2024.
However, another source from August 2024 suggested that the plant would no longer be able to generate electricity. It's unclear which specific plants have been restored and to what extent, especially with ongoing attacks.
