Power Outages Under Two Schedules: Why One Address in Mykolaiv Can Fall Into Different Outage Subgroups

Residents of some buildings in Mykolaiv may find their addresses listed in two different subgroups of the hourly electricity outage schedules. Mykolaivoblenergo explained why this happens and how to find out which schedule applies to a particular apartment. Suspilne reported this on November 11, 2026, citing a response to an information request from the press service of Mykolaivoblenergo JSC.

According to the power company, the reason is that one building can be connected to several power supply lines. This usually happens in apartment buildings with a primary and backup power source, or separate lines for different consumers.

“Being listed in two hourly outage schedule subgroups indicates that the building (usually an apartment building) has two power sources or a backup power line,” Mykolaivoblenergo said.

For example, the apartments in a high-rise building may be connected to one line and belong to one subgroup, while a shop or office on the ground floor is supplied by another line and belongs to a different subgroup. As a result, different consumers at the same mailing address may lose power at different times.

However, having several power supply lines does not mean residents will face longer outages. According to the power company, each consumer receives electricity at any given time from only one line. Therefore, outages follow the schedule for the subgroup to which that particular line belongs. If an address appears in two subgroups, residents are advised to check which one applies to their apartment or entrance.
