Although electricity had been known to be produced as a result of the chemical reactions that take place in an electrolytic cell since Alessandro Volta developed the voltaic pile in 1800, its production by this means was, and still is, expensive. In 1831, Michael Faraday devised a machine that generated electricity from rotary motion, but it took almost 50 years for the technology to reach a commercially viable stage. In 1878, in the United States, Thomas Edison developed and sold a commercially viable replacement for gas lighting and heating using locally generated and distributed direct current electricity.
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.
Just as impressive: Its overall J.D. Power score for customer satisfaction. The 1,000 point score considers price, communications, corporate citizenship, enrollment and renewal, and customer service. At 709, Green Mountain Energy scored the highest of all Pennsylvania companies, well above the 669 state average, and a solid 20 points ahead of the next closest provider we looked at — Constellation.
With moderate fluctuations taken into account, the variable plans is still cheaper. Our bill is approximately $10 more in the winter, but we’d still save $138 over the course of a year. It’s more a question of whether you can roll with the punches of an unpredictable rate, or would sleep easier knowing your bill is going to look the same month after month.
This company has more plan variety than any other we looked at, though most of them seem more flashy than functional. And some seem weirdly niche — like "Connect to Comfort," a 24-month plan that comes with a Hive Hub and a Hive Active Thermostat, smart home devices that allow you to control your heat and A/C via app. Like many of Direct Energy’s plans, how good of a deal it is depends on how closely its offers align with your established habits.
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.
How does that work? Spark Energy buys electricity and competes in the market for the best price -- a competition that ultimately drives prices down and allows us to deliver more value for your money. In Texas, switching to a different electricity provider is kind of like changing to a different long distance company. When you switch to Spark Energy, the utility will continue to deliver electricity to your home but Spark Energy will handle all the billing, including the utility’s delivery fees and the electricity you actually use.

You can organize and shop by pricing at YOUR individual usage level, which allows you to shop and compare energy plans based on the rates you’ll actually see appear on your bill, inclusive of taxes and hidden fees. You won’t be mislead by the “teaser rates” tied with higher usage levels that many homes never experience, as their usage level never reaches that pricing tier.

According to a 2016 J.D. Power national report, switching from the utility company to an REP is not as attractive as it once was. Deregulated markets aim to drive down costs and encourage innovation but has really only succeeded in the second — the price gap between utility rates and retail rates has actually been closing. But deregulation has been successful in championing green energy and improving customer service. This improvement shows up in some impressively high J.D. Power ratings.

You can choose month-to-month plans, long-term contracts, short-term contracts or plans that allow you to pre-pay for electricity, so you know you're never using more electricity than you can pay for. Reliant is here to help you get the electricity plan you need and help you lower your electricity consumption (and electricity bill) wherever you can. Reliant's competitive rates and advanced usage tools make it a premiere energy company in Texas.
When you're looking for electricity plans in Katy, come to Reliant for a variety of plans designed to fit your home and lifestyle. Our special offers cater to almost anyone looking for bonus deals — football fans, jetsetters and people interested in supporting charitable organizations. We even have plans that can save you money when you use most of your electricity in the evenings or on weekends. Environmentally-conscious customers should check out our renewable wind power, solar power and solar sell back plans. 
Here’s something to watch out for: Constellation automatically re-ups your contract when your present contract expires, no matter which plan you choose. It’ll send you two notifications prior to re-enrollment, but if you miss those prompts, you have just until the first meter read of your new contract to exit it. After that, the $150 termination fee will apply. Constellation Energy and Just Energy are the only two companies in our lineup with this policy. The others allow your service to lapse back to your utility company if you don’t personally re-enroll.
If you spend most of your leisure time out of the house, none of these plans will do much for your bottom line. But if home is your favorite place to be, you could profit. Based on the estimates of energy companies, most people use about 31% of their total energy on the weekends. If you go through the average 1,000 kWh per month, you'll get about 310 kWh for free. Using data compiled by the EIA, we estimated 30% of average total energy is also used during evenings (including weekend evenings), working out to about 300 free kWh.
Pennsylvania offers first-time retail shoppers an attractive discount with the Standard Offer Program. The Public Utility Commission has a rotating list of retail providers and upon enrollment, they’ll hook you up with a 12-month fixed-rate plan at seven percent off the current utility price. You can cancel at any time without fees. For 1,000 kWh per month usage, PECO quoted us a price to compare of 7.13 cents. A seven percent discount brings that rate to 6.63 cents per kWh (lower than any plan on our provider list) — a $60 savings after a year of service.

To be clear, no matter fuel portfolio of the plan you choose, your electricity’s make-up will be identical to your neighbors’. Depending on where you live, that could a mix of renewable and fossil fuels. Certificates offset your electricity use by putting an equal amount of clean energy into the electricity grid. If a plan is 100% renewable, that means it’s 100% offset with certificates.


The mid to late 1880s saw the introduction of alternating current (AC) systems in Europe and the U.S. AC power had an advantage in that transformers, installed at power stations, could be used to raise the voltage from the generators, and transformers at local substations could reduce voltage to supply loads. Increasing the voltage reduced the current in the transmission and distribution lines and hence the size of conductors and distribution losses. This made it more economical to distribute power over long distances. Generators (such as hydroelectric sites) could be located far from the loads. AC and DC competed for a while, during a period called the War of Currents. The DC system was able to claim slightly greater safety, but this difference was not great enough to overwhelm the enormous technical and economic advantages of alternating current which eventually won out.[1]
