No. When you’ve chosen a new deal, your new supplier will handle the switching process. They’ll contact you to let you know what date you’ll be transferred over, and they’ll contact you around the switching date to ask for a meter reading. They’ll pass this on to your old supplier so they can send you a final bill. You don’t need to contact your old supplier, as the new supplier will handle everything for you.

The local electric company is the utility – that’s the company who owns the infrastructure, including the poles and power lines that deliver electricity to your home. They are who you call if your power goes out or there's an emergency. But in almost every city in Texas, you must choose another company to supply that energy, called a Retail Electric Provider (REP). These REPs, like Spark Energy, allow you to choose electricity plans that offer competitive prices and plans to meet your needs.
Fixed-rate plans: Fixed-rate plans give customers more stability for their monthly energy bills because the rate a customer signs up with is the rate he or she pays for the length of the plan’s contract. Most fluctuation comes with usage, though transmission and delivery charges and local fees also can change.. Because a fixed-rate plan sometimes spans two-three years, these plans often require a customer credit check and can include early cancellation fees. Fixed-rate plans, because of the continuing market volatility, probably are the best choice for many consumers.
The freedom to choose your energy rates in Maryland is not only available in homes but also to commercial customers. In fact, more than 90% of large businesses in the state have enrolled with alternative suppliers. This competition between energy suppliers to provide lower prices for businesses could be why commercial electric prices in Maryland are lower than the national average this year. If the same competition between suppliers existed for residential customers, prices might also decrease. However, without participation in energy choice, suppliers are not forced to compete for your business. Want to see the available rates? Enter your ZIP code above.

 1.     Contracts:  Before, there were no contracts.  You signed up or you didn’t.  When it’s the only game in town, you have to play by their rules.  Nowadays, you’ll see these ultra-fabulous rates bandied about but it’s only by carefully scrutinizing the fine print that you’ll discover those wonderful rates come with a one-year lock-down or other catches.
