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.
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.

Are you a journalist or researcher writing about this topic who needs to know more about historical rates? Send us details about what you need and we'll get back to you with an answer and a relevant quote from one of our rate experts.

It is unlikely that you’ll see any change at all. You will be receiving the same electricity as you always have been, just from a different company. The only difference you definitely will see will be smaller charges for your electricity. By using our price comparison service you’ll be able to cut costs to your energy tariffs and save more money on electricity and gas.


Because prices from energy companies in Maryland rise and fall depending on the wholesale price of energy, residents may want a more stable rate for a longer period. A fixed-rate energy plan offers you just that, with a consistent rate for the duration of your agreement at current energy prices – regardless of fluctuations in the energy market. This could mean protection from rate spikes and savings for electric utility customers.

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.
