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.


Energy deregulation has been in place for several years however there are still a lot of people who are confused or who have not fully understand the implications, structure, details and workings of energy deregulation. Many simply know that energy deregulation means people now have the power to choose their electric companies – a diversion from the previous system where a single utility company provides services for the generation, transmission and distribution of electricity.

Most common distribution network and generation is done with 3 phase structures, with special attention paid to the phase balancing and resulting reduction of ground current. It is true for industrial or commercial networks where most power is used in 3 phase machines, but light commercial and residential users do not have real-time phase balancing capabilities. Often this issue leads to unexpected equipment behavior or malfunctions and in extreme cases fires. For example, sensitive professional analogue or digital recording equipment must be connected to well-balanced and grounded power networks. To determine and mitigate the cost of the unbalanced electricity network, electric companies in most cases charge by demand or as a separate category for heavy unbalanced loads. A few simple techniques are available for balancing that require fast computing and real-time modeling.[135]

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.

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.
Although electricity prices in the UK aren't cheap some countries have it much worse. In this article I'm going compare internationally to look at who is paying more $/kWh for their energy. I’ve gathered some numbers and crunched a little data to see who is really paying a lot for their power. For my neighbour here in the UK I’ll add a bit more data at the end.
In summary, fixed-rate plans provide a level of certainty and stability in your energy charge since the price will not fluctuate over the life of your contract. If prices suddenly spike, you are protected because your rate is locked in. The flip side is that if rates drop over the life of your contract, you’ll be stuck paying the higher rate. You can incur steep cancellation fees if you change electricity plans or providers before the end of your contract term.
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]
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.
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.
Fixed-rate plans: Fixed-rate plans give customers more stability for their monthly energy bills because the rate a customer signs up with is the rate he or she pays for the length of the plan’s contract. Most fluctuation comes with usage, though transmission and delivery charges and local fees also can change.. Because a fixed-rate plan sometimes spans two-three years, these plans often require a customer credit check and can include early cancellation fees. Fixed-rate plans, because of the continuing market volatility, probably are the best choice for many consumers.

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.
