Why are so many African power utilities effectively bankrupt? For one thing, they are incredibly inefficient. Efficiency can be improved by proper metering, investing in the system to reduce losses, improving collections and being able to cut off non-payers. This last one being easier if there is up-to-date metering and certain big players like government departments and military installations are also forced to obey the rules. These operational improvements and efficiencies will improve the supply of power but will not go far enough.
Even though it’s not ideal for either party, both customers and electric service providers have to purchase electricity at current market rates. Strategically timing your switch to a new electricity provider can help you score the best electric rates in a market that’s out of your control. Another way to feel more in control when switching energy suppliers is to sign up for a fixed-rate plan.

A lot of these financial structures ultimately boil down to being a form of government guarantee, which means that they can’t be scaled up to “solve” countries’ power problems because the governments cannot carry all the liabilities. Countries try to introduce the private sector into power generation precisely to reduce such guarantees, which then end up returning through the back door in the form of government support.

Although electricity prices in the UK aren't cheap some countries have it much worse. In this article I'm going compare internationally to look at who is paying more $/kWh for their energy. I’ve gathered some numbers and crunched a little data to see who is really paying a lot for their power. For my neighbour here in the UK I’ll add a bit more data at the end.

Electricity cannot be stored as easily as gas, it is produced at the exact moment of demand. All of the factors of supply and demand will therefore have an immediate impact on the price of electricity on the spot market. In addition to production costs, electricity prices are set by supply and demand.[120] However, some fundamental drivers are the most likely to be considered.
Prepaid electricity plans are yet another option available to Texas customers. Prepaid plans let you avoid credit checks and deposits by pre-paying for your electricity. Prepaid electricity plans typically do not have a fixed duration and operate on a pay-as-you-go basis. Shopping for prepaid electricity can often yield relatively cheap electricity with no deposit. See Prepaid Electricity: Is It Right For Me? for more.

In terms of renewable sources like solar and wind, weather impacts supply. California’s duck curve[cite] shows the difference between electricity demand and the amount of solar energy available throughout the day. On a sunny day, solar power floods the electricity generation market and then drops during sunless evening, when electricity demand peaks.[117]

The weakest S&P 500 subsector during 2014 was Oil and Gas Drilling, down 46%, which wasn’t very surprising, considering the price of oil dropped 50% from its peak in June through the end of the year. That subsector has risen 6% this year through Monday’s close, showing that there’s plenty of buying taking place. Most other subsectors within energy declined last year, but only three have risen so far in 2015.

Electricity pricing (sometimes referred to as electricity tariff or the price of electricity) varies widely from country to country and may vary significantly from locality to locality within a particular country. Many factors go into determining an electricity tariff, such as the price of power generation, government subsidies, local weather patterns, transmission and distribution infrastructure, and industry regulation. “Electricity prices generally reflect the cost to build, finance, maintain, and operate power plants and the electricity grid.”[1] Some utilities are for-profit, and their prices will also include a financial return for shareholders and owners. Electricity tariffs vary by type of customer, typically by residential, commercial, and industrial connections. Electricity price forecasting is the method by which a generator, utility company, or large industrial consumer can predict the wholesale prices of electricity with reasonable accuracy. The cost to supply electricity varies minute by minute.[1]
Unlike with long-term plans, monthly, variable rate (no-contract) plans have no cancellation fees. You won’t have to pay a penalty if you decide to take your business elsewhere because you found a better deal. Plus, you won’t be left paying more than you should if the market rate for energy trends down. However, if the market prices rise, you’ll have to pay more than those who are in-contract.
