Every single energy supplier in the UK is regulated by Ofgem, the industry regulator. This means that the smaller, lesser-known companies have to follow exactly the same rules as the bigger, more established ones. If a company goes bust, you’ll be covered by Ofgem – they’ll ensure your supply isn’t cut off, and they’ll appoint a new supplier to take over your tariff.

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]

REPs sell electricity rates to Houston energy consumers, but transmission and distribution service providers (TDSPs) deliver the supply of electricity. In Houston, CenterPoint Energy serves as the area's TDSP and works with about 85 REPs. If your power goes out, immediately report the issue to CenterPoint Energy, not your REP. Use the following phone numbers to get in touch with your Houston TDSP.

Usually, fixed-rate renewable-energy plans are among the most expensive options. But in our research, we found Constellation’s green plan rates were comparable to its non-green versions. For example, out of two otherwise identical fixed-rate, 12-month plans from Constellation — “12 Month Fixed Rate 100% Green” and “12 Month Fixed Rate” — it’s the renewable version that currently costs less.

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.

Killeen electricity consumers are located in the Oncor service area. As a transmission and distribution service provider (TDSP), or utility, the company will provide energy supply to your business or home. Don't contact Oncor with any billing or customer service questions. Utility companies handle outages and repairs. Your REP handles questions related to your bills.


Unlike with long-term plans, monthly, variable rate (no-contract) plans have no cancellation fees. You won’t have to pay a penalty if you decide to take your business elsewhere because you found a better deal. Plus, you won’t be left paying more than you should if the market rate for energy trends down. However, if the market prices rise, you’ll have to pay more than those who are in-contract.

As an Exelon company, Constellation Energy is part of one of the biggest — and historically most polluting — corporations in North America. Given Exelon’s vast production energy, ranking on the PERI Toxic 100 list is perhaps not that surprising. The good news is that Exelon is upfront about its room for eco-friendly improvement and make it easy for Constellation customers to go green, too.

Fixed-rate, long-term (contract) plans provide stability in electricity rates. If market energy costs suddenly trend upward where you live, you can rest assured that you won’t have to pay more out of pocket. However, if you want to switch to a different, lower-cost plan before the end of the contract term, you’ll likely have to pay a cancellation or early termination fee.


Oncor, the state’s largest distribution utility which covers Dallas, Fort Worth and much of North Texas, has already agreed to pass all of the millions of dollars of expected tax savings along to consumers.  Oncor agreed to pass the savings along to customers as part of a rate review which is a formal process in which the PUC reviews the appropriateness of rates being charged by the utility.  No exact details have been determined with respect to how the savings will be passed along. The rate review was actually completed before the tax reform bill was passed but there was a commitment in principle to passing along the savings.  It’s not yet know exactly how much Oncor will save from the lower corporate tax rates but with a $245 million tax bill in 2017 future saving are likely to be in the tens of millions of dollars.
In addition to having a healthy dose of Texas pride, we also pride ourselves on providing friendly customer service. Amigo Energy customer service comes in a variety of convenient ways—from our mobile app and desktop portal, to our US-based call center with over 500 customer service agents. No matter which type of Amigo Energy customer support you choose, you’re sure to get the service you need in the timeframe you want it.
Of course, choosing a new electricity supplier or natural gas supplier does not mean you are replacing your utility. Your utility will still deliver whatever energy supply you choose, safely and reliably. Since your utility company depends on where you live, you don't have to worry about choosing a utility company. In general, utilities are responsible for maintaining the energy infrastructure. If you experience a power outage or see a downed power line, call your utility company. These are listed in the Utility Companies column below.
