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. 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 mitigate bad outcomes, but improvements can be achieved only with real-time correction devices (old style switching type, modern low-speed DSP driven and near real-time). 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.
†Offer is available to Texas residential customers who enroll using the Promotion Code “NIGHTSFREE”. Plan bills a monthly Base Charge, an Energy Charge, and passes through Utility Transmission and Distribution delivery charges. Energy Charges for usage consumed between 9pm and 7am each day is credited back on your bill. The utility charges, including delivery charges for night time hours, are passed through at cost and aggregated on your bill. See Electricity Facts Label for details.
Keeping on top: With deregulation, a whole host of electric resellers jumped into the market because there’s a whole lot of electricity to sell: if Texas were a country, it’d be the 11th largest electricity consumer in the world! Just by itself, it uses as much electricity as Spain or Great Britain! That means there’s a whole lot of information you have to find, absorb, and process to make sure you’re getting the best rate for your needs.
Technology also provides a long-term answer, even if it contributes to the problem in the short-term, as described earlier. As renewable power and storage technologies become cheaper and more efficient they will gradually allow for the implementation of cheaper mini-grids and smart grids, increasingly within the reach of the really poor, even in urban areas. Perhaps, grids will one day become marketplaces allowing people to sell excess power from their solar installations to those who have a need for power at that time. Prices can be set dynamically to allow supply to match demand.
ElectricityPlans makes shopping for electricity plans simple and intuitive. We give you the search tools you need to narrow your electricity plan search to specific contract lengths. In addition, you can use advanced search to narrow the search for the perfect electricity plan even further by searching for 100% renewable, prepaid plans, or electricity + extra stuff, for example. We also show each plan’s popularity over the past 30 days so you know what other electricity shoppers have selected.
