If you live in the greater Houston area, there are over 60 different energy suppliers competing for your business. Many of these providers have websites that are confusing and difficult to navigate, their rates buried in misleading advertising and dense jargon. Who has the time to sort through and keep track of options across all these different sites?
We carefully screen Texas electricity providers in your area. Then, we list electricity rates and plans from top providers in a user-friendly format on our website, so you can compare the information. We handle the complex concerns and considerations, so you don’t have to. With our assistance, you no longer need to track down different electricity companies, rates, and plans, because we provide all the information you need to choose the best provider.

The two most common distinctions between customer classes are load size and usage profile. In many cases, time-of-use (TOU) and load factor are more significant factors than load size. Contribution to peak-load is an extremely important factor in determining customer rate class. Consumer loads may be characterized as peak, off-peak, baseload, and seasonal. Utilities rate each load differently, because each has different implications for a power system.


Snowpack, streamflows, seasonality, salmon, etc. all affect the amount of water that can flow through a dam at any given time. Forecasting these variables predicts the available potential energy for a dam for a given period.[124] Some regions such as the Egypt, China and the Pacific Northwest get significant generation from hydroelectric dams. In 2015, SAIDI and SAIFI more than doubled from the previous year in Zambia due to low water reserves in their hydroelectric dams caused by insufficient rainfall.[125]
*Save Over £390 - Over 10% of the estimated quotations raised by users of the Simply Switch Website to switch their gas and electricity suppliers between 01/02/2015 - 01/06/2015 produced a predicted annual saving of £390 or more. Current combined spend for gas and electricity of between £84 and £6869. Savings may have included Direct Debit and online discounts. Energy prices vary by usage and postcode.
When you’re choosing a new energy deal, think about whether to go for dual fuel (where you get both your gas and electricity from the same company) or separate tariffs (where you get gas from one company, and electricity from another). It’s worth checking both options, as the combined price of separate tariffs can sometimes be less than a dual fuel offer.
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.
Utility companies are responsible for transmission and delivery of electricity even in energy deregulated parts of Texas and should be contacted in the event of a power outage. Your retail energy supplier may provide you competitive electric rates or exceptional customer service, but they cannot repair power lines or restore your service. In the case of an emergency, contact:
In terms of renewable sources like solar and wind, weather impacts supply. California’s duck curve[cite] shows the difference between electricity demand and the amount of solar energy available throughout the day. On a sunny day, solar power floods the electricity generation market and then drops during sunless evening, when electricity demand peaks.[117]
Excessive Total Harmonic Distortions (THD) and not unity Power Factor (PF) is costly at every level of the electricity market. Cost of PF and THD impact is difficult to estimate, but both can potentially cause heat, vibrations, malfunctioning and even meltdowns. Power factor is the ratio of real to apparent power in a power system. Drawing more current results in a lower power factor. Larger currents require costlier infrastructure to minimize power loss, so consumers with low power factors get charged a higher electricity rate by their utility.[130] True power factor is made of displacement power factor and THD. Power quality is typically monitored at the transmission level. A spectrum of compensation devices[131] mitigate bad outcomes, but improvements can be achieved only with real-time correction devices (old style switching type,[132] modern low-speed DSP driven[133] and near real-time[134]). Most modern devices reduce problems, while maintaining return on investment and significant reduction of ground currents. Power quality problems can cause erroneous responses from many kinds of analog and digital equipment, where the response could be unpredictable.

You can rest easy knowing you’re choosing the best from the best.


Wind and solar power are non-dispatchable. Such power is normally sold before any other bids, at a pre-determined rate for each supplier. Any excess is sold to another grid operator, or stored, using pumped-storage hydroelectricity, or in the worst case, curtailed.[116] Curtailment could potentially significantly impact solar power’s economic and environmental benefits at greater PV penetration levels.[117] Allocation is done by bidding.[118]
OPEC nations, along with Russia and Mexico, have refused to cut production, which is their traditional tool to prop up oil prices, out of fear of losing market share to the U.S., which has transformed the international oil market by greatly expanding hydraulic fracturing over the past decade. And U.S. producers might not lower production as quickly as some investors expect because of the significant improvement in the efficiency of horizontal fracturing wells.
During your search, it’s important to keep in mind that your timing may be the most important contributor to actually finding the lowest electricity rates. So when is the best time to find cheap electricity rates? With the market rates for electricity fluctuating on a daily basis, we know that pinpointing the best time to switch may seem difficult. Here at Think Energy, we want to provide you with information to determine the best time for you to score the lowest energy rates.
When you’re choosing a new energy deal, think about whether to go for dual fuel (where you get both your gas and electricity from the same company) or separate tariffs (where you get gas from one company, and electricity from another). It’s worth checking both options, as the combined price of separate tariffs can sometimes be less than a dual fuel offer.
The table below shows simple comparison of electricity tariffs in industrialised countries and territories around the world, expressed in US dollars. The comparison does not take into account factors including fluctuating international exchange rates, a country's purchasing power, government electricity subsidies or retail discounts that are often available in deregulated electricity markets.[5]
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.
Studies show that generally demand for electricity is driven largely by temperature. Heating demand in the winter and cooling demand (air conditioners) in the summer are what primarily drive the seasonal peaks in most regions. Heating degree days and cooling degree days help measure energy consumption by referencing the outdoor temperature above and below 65 degrees Fahrenheit, a commonly accepted baseline.[123]
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 misled by the “teaser rates” tied with higher usage levels that many homes never experience, as their usage level never reaches that pricing tier.
