Every single energy supplier in the UK is regulated by Ofgem, the industry regulator. This means that the smaller, lesser-known companies have to follow exactly the same rules as the bigger, more established ones. If a company goes bust, you’ll be covered by Ofgem – they’ll ensure your supply isn’t cut off, and they’ll appoint a new supplier to take over your tariff.
Technology also provides a long-term answer, even if it contributes to the problem in the short-term, as described earlier. As renewable power and storage technologies become cheaper and more efficient they will gradually allow for the implementation of cheaper mini-grids and smart grids, increasingly within the reach of the really poor, even in urban areas. Perhaps, grids will one day become marketplaces allowing people to sell excess power from their solar installations to those who have a need for power at that time. Prices can be set dynamically to allow supply to match demand.
The inclusion of renewable energy distributed generation and AMI in the modern electricity grid has introduced many alternative rate structures. Simple (or fixed) rate, tiered (or step) rate, TOU, demand rates, tiered within TOU, seasonal, and weekend/holiday rates are among the few residential rate structures offered by modern utilities. The simple rate charges a specific dollar per kilowatt ($/kWh) consumed. The tiered rate is one of the more common residential rate programs, and it charges a higher rate as customer usage increases. TOU and demand rates are structured to help maintain/control a utility’s peak demand. The concept at its core is to discourage customers from contributing to peak-load times by charging them more money to use power at that time.

There was a time when electricity was electricity.  Like so many other places around America, in Houston, electricity didn’t mean “cheap electricity”.  But you moved into your home and you called the utility and they turned on the power and the bill came in and you paid it every month.  Oh, sure, you might grumble at the amount but then you’d go around and yell at the kids for leaving the lights on and the TV blaring with nobody in the room or maybe you’d look into buying more energy-efficient appliances.  When it came down to it, the Bill was the Bill.  Either you paid the bill or you ate dry packet meals, had cold showers, and watched TV by peering through the neighbor’s window after dark (preferably once they’d turned the TV on).  What’s that?  You want cheap electricity?  Sure thing:  call 1-800-WHO-CARES any time during regular business hours of 2:17am to 3:04am Sundays only.
As a residential or commercial customer, you’ll enjoy competitive rates, flexible contracts, and personalized plans that give you the power to choose what’s best for you. And we offer no-deposit electricity for well-qualified customers and deposit payment plans for those with less than desirable credit so that switching retail electric providers won’t break the bank.‡ When you switch to Amigo Energy today, you’ll switch on the power of convenience and affordability.
But competition didn't necessarily end up cutting prices, according to the report. One contributing factor is confusion among customers as they try to choose among scores of retail electricity providers and the overwhelming variation of plans, leading many to just stick with familiar companies rather than look for better deals, according to the Texas Coalition for Affordable Power .

The table below shows simple comparison of electricity tariffs in industrialised countries and territories around the world, expressed in US dollars. The comparison does not take into account factors including fluctuating international exchange rates, a country's purchasing power, government electricity subsidies or retail discounts that are often available in deregulated electricity markets.[5]

You can organize and shop by pricing at YOUR individual usage level, which allows you to shop and compare energy plans based on the rates you’ll actually see appear on your bill, inclusive of taxes and hidden fees. You won’t be misled by the “teaser rates” tied with higher usage levels that many homes never experience, as their usage level never reaches that pricing tier.
