From July 1, 2025, Ukraine will implement a new European voltage standard of 230/400 V.

This is confirmed by the resolution of the National Commission for State Regulation in the Sectors of Energy and Public Utilities (NCRECP) No. 550 dated April 15.

The document amends the Code of Distribution Systems, introducing European norms for determining electricity quality parameters. The nominal voltage will now be 230/400 V, with permissible deviations of up to 10% (from 207 to 253 V).

The DSTU EN 50160:2014 standard, which regulated voltage characteristics in electrical networks, lost its validity in March 2024. In May of the same year, a new standard harmonized with the European EN 50160 was approved, coming into effect on March 1, 2025.

The NCRECP expects that the transition to European standards will positively impact the quality of electricity supply. Stable voltage will reduce the risk of damage to household appliances sensitive to fluctuations and decrease the need for additional protective devices such as stabilizers. Furthermore, this will enhance energy efficiency, allowing electrical devices to operate in optimal conditions without overloads and power losses.

The DTEK group emphasizes that household appliances are manufactured in accordance with EU requirements, so the transition to the new voltage standard will not harm them.
