Ukraine made a transition to 230 V. What will change for all of us, – DTEK Kyiv Regional Grids explains
Thermal power generation02 July 2025
On July 1, 2025, the entire country made a transition to the new voltage standard 230 V. This decision was approved by the state regulator NEURC. For over 3 years, our energy system has been working in synch with the European one, and the change of the standard is the next logical step to transition to the technical standards, common with the EU. Distribution System Operator DTEK Kyiv Regional Grids has long been ready to work with 230 V and notes that Ukrainians will barely notice these changes.
Every year, DTEK Kyiv Regional Grids upgrades and modernizes its energy equipment, therefore, the grids in the Kyiv region will be able to work with new voltage standard.
The only change that Ukrainian consumers will see is a new permissible deviation of voltage – from 207 V to 253 V (±10 % of 230 V). Thus, we recommend considering new parameters when setting up the voltage relay in your home, providing you are using one. However, modern appliances have long been designed to work in this specific range.
Let us remind that smart consumption is the best help to the energy system. Do not turn on several electrical appliances at once, use powerful appliances from 10:00 to 18:00 in sunny days.
