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:
After Senate Bill 7 went into effect in January 2002, nearly 6 million power customers became eligible to choose their energy supplier. That number has grown through the years. By deregulating the state’s energy market, the Texas Senate gave constituents the power to choose. The process of energy deregulation in Texas dismantled the utilities’ monopoly over the electric market and encouraged customers to explore their energy options.

In states with energy choice, the open market is not only for residents. Businesses also can take advantage of pricing and plans available through an energy supplier. In some states, only business customers have energy choice. Across the United States, the average business consumes 6,278 kWh of electricity per month and receives a bill of nearly $655.  
Another unwelcome side effect of not knowing your average monthly kWh usage level is that you may end up paying more than you expect. This can occur when a customer inadvertently shops an electric rate based on a higher usage level than they actually use. Electricity suppliers commonly advertise their electric rates associated with the highest (2000 kWh) usage levels since those tend to be the lowest rates.

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.
Short-term prices are impacted the most by weather. Demand due to heating in the winter and cooling in the summer are the main drivers for seasonal price spikes.[121] In 2017, the United States is scheduled to add 13 GW of natural-gas fired generation to its capacity. Additional natural-gas fired capacity is driving down the price of electricity, and increasing demand.
For example, in 2012, Hawaii residents had the highest average residential electricity rate in the United States (37.34¢/kWh), while Louisiana residents had the lowest average residential electricity costs (8.37¢/kWh). Even in the contiguous United States the gap is significant, with New York residents having the highest average residential electricity rates in the lower 48 U.S. states (17.62¢/kWh).[6]
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]
Although conventional long-term contracts may offer you very low kilowatt-hour prices, these contracts also impose many obligations and hefty penalties for non-compliance. No deposit electric plans tend to have a slightly higher energy price that long-term contracts, but allow more freedom in how you pay for your electricity. The most relevant differences between no deposit electricity plans and conventional contracts are summarized in the following table:

Since consumer demand directly affects energy rates, it’s important to note seasonal trends of demand throughout the year. Overall, demand tends to be higher during the winter and summer months and lower during the fall and spring months. This pattern isn’t shocking since it’s normal for people to require more energy during extreme heat and extreme cold.
Dallas area residents now have the option for choosing their electric provider. However, with all of the different plans that are available, it can be difficult to make the right decision for your particular electricity needs. You may find yourself overwhelmed by the number of options presented to you by all the electric company advertisements or concerned about shady marketing gimmicks.
