Electricity outage

Outage is a serious problem to the energy supplier so how does energy meet the demands. Let's take a look in a country e.g Bangladesh.
The country has severe outage problems and still trying to meet the country's energy demand it also has other energy sources such as solar power for electricity generation but it's still not enough because the country's pay for electricity is not pay as you use but a fixed monthly fee for electricity supplied to each and individual customers with no obligations whatsoever. A customer doesn't need to satisfy it's energy use it can use as much as it wants for the price of single tariff for all use. It's not just an outage problem it causes but also the environment. The government has made some changes to it's electricity supply policy recently in the past.
