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.


Electricity is deregulated in two Canadian provinces: Ontario and Alberta. Both markets showed price spikes in the first year of dereguation, but then settled down into a volatile but reasonably stable environment. Alberta's market is dominated by fossil fuel generation and as such reacts more closely to the price of natural gas. Ontario's generation mix is about 50% nuclear.[1]
The organization of the electrical sector of a country or region varies depending on the economic system of the country. In some places, all electric power generation, transmission and distribution is provided by a government controlled organization. Other regions have private or investor-owned utility companies, city or municipally owned companies, cooperative companies owned by their own customers, or combinations. Generation, transmission and distribution may be offered by a single company, or different organizations may provide each of these portions of the system.
Although electricity had been known to be produced as a result of the chemical reactions that take place in an electrolytic cell since Alessandro Volta developed the voltaic pile in 1800, its production by this means was, and still is, expensive. In 1831, Michael Faraday devised a machine that generated electricity from rotary motion, but it took almost 50 years for the technology to reach a commercially viable stage. In 1878, in the United States, Thomas Edison developed and sold a commercially viable replacement for gas lighting and heating using locally generated and distributed direct current electricity.
