New Voltage Standard in Ukraine
As of July 1, 2025, Ukraine will implement a new European voltage standard of 230/400 V.
This is stated in the decree of the National Commission for State Regulation in the Spheres of Energy and Utility Services (NERC) No. 550 dated April 15.
The document amends the Distribution System Code to incorporate European standards for power quality parameters. The nominal voltage will now be 230/400 V, with permissible deviations of up to 10% (ranging from 207 to 253 V).
The DSTU EN 50160:2014 standard, which outlined voltage characteristics in electrical networks, became invalid in March 2024. In May of the same year, a new standard harmonized with the European EN 50160 was approved, taking effect on March 1, 2025.
NERC expects that the transition to European standards will positively impact the quality of electricity supply. Stable voltage will reduce the risk of damage to sensitive household appliances and decrease the need for additional protective devices such as stabilizers. Furthermore, this will enhance energy efficiency, allowing electrical devices to operate in optimal mode without overloads and power losses.
The DTEK group emphasizes that household appliances are manufactured according to the European Union's standards, so the transition to the new voltage standard will not harm them.
