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.
But, again, the concept isn’t difficult. Let’s use the city of Joliet as an example. Joliet’s traditional utility for the 60435 area code is Commonwealth Edison. As of late February, its price to compare is 7.195 cents per kilowatt hour (kWh); at this writing, four plans from ChooseEnergy.com featured suppliers with lower rates, including one that’s 18% cheaper and uses all green energy.
Landsvirkun, Iceland’s national power company, offers electricity to buyers for as low as $0.043 per kWh, which is nearly on par with what can be found in Washington State. Coupled with 20% corporate tax, the nation’s low energy prices have attracted not just data centers, methanol producers, silicon metal producers but also aluminum companies—which, again, consume massive amounts of electricity.
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.
Switching electricity supplier could shave pounds off your bills. But it’s not always about how much hard cash you could save. You might be fed up with poor customer service, you might want greater visibility of your usage through an app or you might want to choose your supplier based on their green credentials, or whether they supply a smart meter.
