Energy sellers must provide collateral to ERCOT to cover expected future costs of buying wholesale electricity and if the companies don’t have enough capital, they get shut down. Breeze Energy, a Dallas-based electricity retailer that sold wind-energy plans to 9,800 customers including many in the Houston area, got caught in that financial squeeze when it defaulted on its collateral obligations.
As a result, power companies have shut down Texas coal plants unable to compete with lower-cost generators. Meanwhile, the low electricity prices of recent years — a function of cheap natural gas — and small profits have discouraged companies from investing in new power plants. ERCOT, which oversees about 90 percent of the state’s power grid, said power reserves that are called on when demand peaks on the hottest summer days have shrunk to the lowest levels since Texas deregulated power markets in 2002.

The city of Houston has a long and rich history. Named after General Sam Houston, it is the largest city in the state of Texas and the fourth largest city in the United States. Home to 26 fortune 500 companies, affordable housing, world-class museums and cultural landmarks, it’s no wonder that the city is ranked one of the best places to live in the state of Texas.
In summary, fixed-rate plans provide a level of certainty and stability in your energy charge since the price will not fluctuate over the life of your contract. If prices suddenly spike, you are protected because your rate is locked in. The flip side is that if rates drop over the life of your contract, you’ll be stuck paying the higher rate. You can incur steep cancellation fees if you change electricity plans or providers before the end of your contract term.

The most advantageous part about their plan is that they offer prepaid electricity, where you pay beforehand and avoid the usual surprise you get every month when you see your bill. This is super convenient when used with text alerts because they can tell you how much electricity you’ve used, how much money you’ve saved, how much you have remaining on your prepaid balance, and the days remaining too.
