Learn to understand the electricity bill
The electricity bills They are always a headache for the vast majority of consumers since it is one of the most complex and varied documents that any client handles on a daily basis. A survey by the Organization of Consumers and Users (OCU) found that only the 11% of consumers understands the entire bill. In fact, there are many people who do not know if they are in a free market or a regulated market.
It seems clear that there two basic concepts: fixed cost mainly of contracted electricity and variable cost of consumption per client, it must be remembered that there are off-peak hours in which costs are lower (Monday to Friday from 0:00 to 08:00, in addition to Saturdays and Sundays during all day), flat hours with an average cost (8:00 a.m. to 10:00 a.m., from 2:00 p.m. to 6:00 p.m. and 10:00 p.m. to 12:00 a.m. (Monday to Friday) and finally, the expensive schedule (10:00 a.m. 00 to 14:00 and 18:00 to 22:00), hours that you should avoid if you want save on your electricity bill.
In addition, other expenses such as meter rental or taxes are added.
