From January to March, while still inside the 2025/26 heating season, energy workers already began implementing a preparation plan for the new season. During this period, over 700 km of overhead power lines and 831 substations, transformer and distribution points were renewed in the city of Kyiv and in Odesa, Dnipropetrovsk, Kyiv and Donetsk regions. Energy workers in the Donetsk region are directing all resources at restoration of grids, damaged by the hostilities. Due to this and due to the difficult security situation, scheduled activities are not being carried out. Nevertheless, specialists conduct repairs wherever it is possible and critical for ensuring power supply.

In 2026, DTEK Grids DSO plan to repair a total of more than 8,000 km of power lines, over 6,000 power facilities of various voltage class, and clear more than 8,000 km of power line routes from branches and brushwood to prevent emergencies during bad weather.

Additionally, energy workers plan to reconstruct more than 145 km of power lines and 114 power facilities, build new 30 km of cable lines and 89 transformer substations.

The list of facilities to be repaired and modernized is formed based on the technical condition of equipment and results of its operation during the previous period. The main priority – sections of the grids with the highest level of wear and the ones that provide power supply to a large number of customers and to the critical infrastructure.

“Preparation for the heating season is a continuous process that lasts throughout the year and is a key element for providing stable power supply to the Ukrainians. Repairs and upgrades of the energy infrastructure make it possible to form more sustainable energy systems, capable of withstanding peak loads. And thus, reducing the risk of power outages,” – explained DTEK Grids CEO Alina Bondarenko.

The task of DTEK Grids DSO is not only to restore damaged equipment, but also to systematically improve reliability of power supply even during the war.
