From July 1, the voltage standard in the electricity grid will change
In Ukraine, instead of the current 220 volts, 230 volts will be used
European approaches to determining power supply quality parameters will come into effect in Ukraine from July 1, 2025. This is stated in the resolution of the National Commission for State Regulation of Energy and Utilities (NCRECU).
In particular, a transition to a nominal voltage of 230/400 V will be introduced.
The National Commission for the Regulation of Electricity and Energy of Ukraine notes that one of the key innovations is the establishment of clear limits for permissible voltage deviation: from 207 to 253 V (±10% of the nominal value of 230 V).
The Commission expects that these changes will have a positive impact on the quality of electricity supply: "Stable voltage will reduce the risks of damage to household appliances sensitive to fluctuations, and will also reduce the need for additional protective equipment, such as stabilizers. In addition, this will contribute to increasing energy efficiency - electrical appliances will be able to operate in optimal mode, without overloads and power losses," the NEURC emphasized.
