In this free market competing electricity retailers buy electricity wholesale from private power generators to sell at retail to around 85% of Texas residents. The partnership between generators and retailers is governed by the Electric Reliability Council of Texas, or ERCOT, which attempts to balance the power grid’s electricity supply and demand by purchasing small amounts of electricity at 15-minute intervals throughout the day.
TDSPs or EDUs are the companies and people who own and maintain utility poles and power lines. They are the ones that you call when your power goes out. These utility companies are responsible for the physical delivery of electricity to your home or business. Before deregulation, everyone was required to buy their electricity from their local utility company.  With deregulation, the supply of electricity was opened to competition while the delivery of electricity continues to be regulated by the state’s public utility commission.
The consumer has the choice between buying from their local utility (Local Distribution Company - LDC) or from one of the deregulated suppliers. There is a large range of contract options from a variable price to 1,3 or 5 year fixed prices. Electricity provider switching is difficult once the consumer is in one of these contracts, unless they are close to the end of a fixed price contract. However, as of January 2010 there is a maximum termination penalty allowed.[2]
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.
