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.
Variable rate plans are always month-to-month, save for three-month intro specials in which your rate stays the same for those early months. Fixed rate plans, on the other hand, are available for periods ranging from six to 36 months. The contract lengths, and how that length influences the price per kWh rate, varies enormously from company to company. Some companies offer lower rates when you enroll for longer periods. Others raise the rate slightly. The competing rationale: You will be paying them for longer so you get a break, or you have that price locked in when energy rates inevitably rise. One rule of thumb — the longer the contract, the higher the cancellation fee.
Residential and business consumers in deregulated energy markets have the power to choose their energy supplier. SaveOnEnergy.com® gives consumers the opportunity to compare suppliers and find energy plans that satisfy their needs and budget. 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!
Texas deregulated most of the state's electricity markets in 2002, a move aimed at lowering electricity costs by letting consumers choose their own electric power providers and their own plans. Some parts of Texas continued to be regulated, including those that get power from municipal utilities, electric cooperatives and investor-owned utilities that operate outside the state's primary power grid.

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.
Deregulation seeks to drive down costs and spur innovation by breaking up energy monopolies. In their place, two separate entities take care of 1) generation and 2) distribution. Electric Generation Suppliers (EGS) create electricity and set their own prices for consumers. Electric Distribution Companies (EDC), a.k.a., your local utility company, bring that electricity to your home.

When it comes to the electricity itself, there is no difference at all. A cheap electric supply is the same electricity, it's simply provided by a new supplier (unless you opt for green energy - more on that here). As suppliers buy and generate different sets of energy they also have different prices. What's more, you might be on a tariff that is simply more expensive, such as a standard tariff. If you decide to switch electricity don't equate a lower price with worse service.
Here’s something to watch out for: Constellation automatically re-ups your contract when your present contract expires, no matter which plan you choose. It’ll send you two notifications prior to re-enrollment, but if you miss those prompts, you have just until the first meter read of your new contract to exit it. After that, the $150 termination fee will apply. Constellation Energy and Just Energy are the only two companies in our lineup with this policy. The others allow your service to lapse back to your utility company if you don’t personally re-enroll.
