An additional bill was passed in 1999 that helped further establish a competitive electricity market by creating a price floor to prevent established energy providers from underselling emerging providers. In 2002, Texas finalized deregulation when the Public Utility Commission gave ERCOT the responsibility of managing and monitoring the Texas electricity market. The market opened up to around 6 million Texas power customers.


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]

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.
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.
