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.
On the other hand, month-to-month variable rate (no-contract) plans don’t have cancellation fees. You won’t be penalized if you find a better deal elsewhere and want to make another switch.  And, you won’t be stuck paying more than you should be if the market rate for electricity trends down.  But, if it goes up, you’ll be paying more than your in-contract neighbors, and you’ll likely want to shop around again for a better deal.

In some states, utilities can also generate and sell electricity, but customers aren’t forced to buy the electricity from the utility company. They may choose from either the utility or available electricity providers. Before signing up for electricity service, we recommend checking the local utility’s electricity supply rate by checking their rates online or contacting them directly.
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 more cool air you lose, the harder your air conditioning unit works and the higher your electricity bill will be. Install blinds, hang curtains or get storm windows made to keep cool air from seeping out. Even mesh screens, on the outside of your home, will help deflect solar radiation. You might even consider replacing old windows that leak cold air and let in heat.
Ironically, technology can make the utilities’ problem worse, not better—at least in the short term. In the past, grids were developed because it was cheaper to generate large quantities of power and distribute it over wide distances, rather then generate smaller quantities closer to the place of use. It is for this reason that electricity is seen as a business that benefits from “economies of scale”.

Know that Green Mountain’s cheapest advertised plans are all variable rate plans. “Pollution Free,” “Pollution Free Try 3,” or “SolarSPARC 10 Try 3” all advertise a great initial rate — a full cent below Pennsylvania’s 8.49 cent “price to compare” — but its variable rates means the company can raise them at any time. The two “Try 3” plans just lock in the low introductory rate for three months instead of one. The flipside of fixed rate: Should prices fall, you’ll be locked into a contract with a constant, elevated rate for two more months.
Fixed-rate supply plans offer price-protected supply rates for the length of a term agreement. The price per kilowatt hour (kWh) will remain the same throughout your term, even if the market price fluctuates. A fixed-rate supply plan can range from three months to five years, so it’s important to find the term length that works best for your situation.
We’ve done some of the work for you. We homed in on five of the biggest electric companies in Pennsylvania: Constellation Energy, Direct Energy, FirstEnergy Solutions, Green Mountain Energy, and Just Energy. We compared their plans, rates, special offers, and philanthropies, then dug into the contract fine print to uncover sneaky fees and the truth about discounts. Because most providers offer a range of options, we also looked at the companies behind the plans — paying attention to their corporate impact, customer service reputation, and customer resources in particular.
The Virgin Islands, in fact, has some of the world’s most expensive electricity precisely because it doesn't have the means to diversify its energy portfolio. The territory depends entirely on imported crude oil to run its petroleum power plants, and as a result, its energy goes for between 50.8 and 54.8 cents per kWh as of last year. This business-repelling price far exceeds that of countries whose energy is considered steep compared to the U.S. average, namely, Denmark ($0.41 cents per kWh), Germany ($0.35), Spain ($0.30), Australia ($0.29) and Italy ($0.28). This year the Virgin Islands has tried to reel in businesses with substantial tax breaks, but the savings might not be enough to offset the eye-popping electricity bill.

Variable-rate supply plans, as the name suggests, have a rate that varies based on the market price of electricity. Seasonal and market fluctuations can affect supply rates. While variable-rate supply plans can allow you to take advantage of market-price lows, there is the possibility of paying for high supply rates when demand is at its peak. These plans offer great flexibility.

Consumers in Houston, Dallas, Fort Worth and Corpus Christi were promised bargains on electricity when the Texas Legislature deregulated the electricity market. But 16 years later they're still paying more for electricity than their counterparts in cities Texas lawmakers exempted from deregulation such as Austin and San Antonio, according to the Texas Coalition for Affordable Power which analyzed federal electricity pricing data.
