In Russia the cost of electricity for kilowatt-hour depends on the region, from that city is or a village, from that gas stove in the house (apartment) or electric, from which electric meter is used in the house (apartment). For example, I live in the Ural region, in the city, in the apartment and I have a two-timer electric meter, and there is no electric stove.
Day rate (the amount of electricity used from 7 am to 23 pm) - 0.0562 €/kwh, and the night rate (the amount of electricity used from 23 pm to 7 am) - 0.0281 €/kwh.
Those who have an electrical counter shows only one rate pay 0.0505 €/kwh.
