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.
The problem is that across Africa, the vast majority of the power utilities are effectively bankrupt. Another World Bank study (pdf) on African Utilities shows that only two of the 39 African utilities surveyed, in the Seychelles and Uganda, were able to generate enough cash to cover both their operating costs and capital expenditures necessary to invest in the maintenance and expansion of the grid. In fact, only 19 of the 39 companies were able to generate enough cash to cover their day-to-day operating costs. It means the rest were not even able to pay everyday costs, like salaries, in full.
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.
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]

Residential and business consumers in deregulated energy markets have the power to choose their energy supplier. The power to choose gives consumers the opportunity to compare suppliers and find energy plans that satisfy their usage needs and budget requirements. Whether in a deregulated city in Texas, New York, Ohio or another state, you can shop for electricity or natural gas and find the best plan for you!

In states with energy choice, the open market is not only for residents. Businesses also can take advantage of pricing and plans available through an energy supplier. In some states, only business customers have energy choice. Across the United States, the average business consumes 6,278 kWh of electricity per month and receives a bill of nearly $655.  
You may have noticed a lot of electric companies offering a ton of plans and services. But not all light companies in Texas are created equal. So which one is right for you? At Amigo Energy, we want you to trust that you’re getting a custom energy plan at a good price—not just a quick fix that’ll cost you more down the road. In fact, JD Power gave us four out of five stars for pricing, beating out a ton of other large retail electricity providers.4
The simplest model for day ahead forecasting is to ask each generation source to bid on blocks of generation and choose the cheapest bids. If not enough bids are submitted, the price is increased. If too many bids are submitted the price can reach zero or become negative. The offer price includes the generation cost as well as the transmission cost, along with any profit. Power can be sold or purchased from adjoining power pools.[112][113][114]
Keeping on top:  With deregulation, a whole host of electric resellers jumped into the market because there’s a whole lot of electricity to sell:  if Texas were a country, it’d be the 11th largest electricity consumer in the world!  Just by itself, it uses as much electricity as Spain or Great Britain!  That means there’s a whole lot of information you have to find, absorb, and process to make sure you’re getting the best rate for your needs.
 1.     Contracts:  Before, there were no contracts.  You signed up or you didn’t.  When it’s the only game in town, you have to play by their rules.  Nowadays, you’ll see these ultra-fabulous rates bandied about but it’s only by carefully scrutinizing the fine print that you’ll discover those wonderful rates come with a one-year lock-down or other catches.
Power generation projects, which have to sell their power to these bankrupt utilities, require creative financing structures to get around these problems. In a bid to reduce their risk when financing these projects, bankers employ financial tools like put call options agreement or World Bank partial risk guarantees. The problem is these tools add complexity and cost which end up being passed on to the end-user or worsen the financial state of the power utility.
Customers can find deals in competitive electricity markets if they take the time and effort to look at web sites such as powertochoose.org, the official comparison shopping site of the Public Utility Commission. The study cited a PUC survey of retail electricity offerings in Houston that showed nine deals in March that were lower than the regulated price of electricity in San Antonio.

How does that work? Spark Energy buys electricity and competes in the market for the best price -- a competition that ultimately drives prices down and allows us to deliver more value for your money. In Texas, switching to a different electricity provider is kind of like changing to a different long distance company. When you switch to Spark Energy, the utility will continue to deliver electricity to your home but Spark Energy will handle all the billing, including the utility’s delivery fees and the electricity you actually use.
