In deregulated states, electricity providers simply can't do business like that because consumers like you are demanding energy from renewable sources. Threats of global warming are too terrible to be irresponsible with our energy sources anymore. As a result, each electric company is pushing forward to find renewable energy sources that are cheaper, cleaner, and more reliable than older forms of energy.
There was a time when electricity was electricity. Like so many other places around America, in Houston, electricity didn’t mean “cheap electricity”. But you moved into your home and you called the utility and they turned on the power and the bill came in and you paid it every month. Oh, sure, you might grumble at the amount but then you’d go around and yell at the kids for leaving the lights on and the TV blaring with nobody in the room or maybe you’d look into buying more energy-efficient appliances. When it came down to it, the Bill was the Bill. Either you paid the bill or you ate dry packet meals, had cold showers, and watched TV by peering through the neighbor’s window after dark (preferably once they’d turned the TV on). What’s that? You want cheap electricity? Sure thing: call 1-800-WHO-CARES any time during regular business hours of 2:17am to 3:04am Sundays only.
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.
On the one hand, long-term, fixed-rate (contract) plans offer stability in pricing. If energy supply costs suddenly go up in your area, you won’t be left paying more than what you bargained for. You’ll have peace-of-mind. If you want to switch out of your contract before it ends with a lower cost plan, you’ll likely face a cancellation fee (early termination fee).
