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.
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.
