You're question is unclear. Most rates are unit rates. Miles per hour implies 1 hour which is a unit (1) rate.
Cost per unit of electricity depends the type of generation used. ie:- thermal hydel, nuclear etc. hydel electricity is cheaper and now a days it cost less than Rs.10 per unit in India. whereas thermal electricity cost less than Rs. 20 per unit

A rate is a ratio of two quantities: miles per hour, calories per cookie, dollars per person, ... a unit rate just specifies the units (miles, hours) of the two quantities.
An electric current is the amount of electrons per unit time or seconds.
It could be 25 per 2 hours or 6.25 per 30 minutes.
When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
