Why are so many African power utilities effectively bankrupt? For one thing, they are incredibly inefficient. Efficiency can be improved by proper metering, investing in the system to reduce losses, improving collections and being able to cut off non-payers. This last one being easier if there is up-to-date metering and certain big players like government departments and military installations are also forced to obey the rules. These operational improvements and efficiencies will improve the supply of power but will not go far enough.
When it comes to pinpointing specific months rather than seasons, every part of the country has its own highest- and lowest-demand months. For example, hotter states, such as Texas, have their lowest demand anytime between December and March.[2] When it comes to your own location, you can determine typical demand trends by taking a look at your area’s weather patterns or your billing records that showcase your personal monthly demand levels.
Every single energy supplier in the UK is regulated by Ofgem, the industry regulator. This means that the smaller, lesser-known companies have to follow exactly the same rules as the bigger, more established ones. If a company goes bust, you’ll be covered by Ofgem – they’ll ensure your supply isn’t cut off, and they’ll appoint a new supplier to take over your tariff.
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]

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]
Electricity cannot be stored as easily as gas, it is produced at the exact moment of demand. All of the factors of supply and demand will therefore have an immediate impact on the price of electricity on the spot market. In addition to production costs, electricity prices are set by supply and demand.[120] However, some fundamental drivers are the most likely to be considered.
The inclusion of renewable energy distributed generation and AMI in the modern electricity grid has introduced many alternative rate structures. Simple (or fixed) rate, tiered (or step) rate, TOU, demand rates, tiered within TOU, seasonal, and weekend/holiday rates are among the few residential rate structures offered by modern utilities. The simple rate charges a specific dollar per kilowatt ($/kWh) consumed. The tiered rate is one of the more common residential rate programs, and it charges a higher rate as customer usage increases. TOU and demand rates are structured to help maintain/control a utility’s peak demand. The concept at its core is to discourage customers from contributing to peak-load times by charging them more money to use power at that time.
There are over 60 different energy suppliers competing for your business on any given day in Texas. Many of these electric companies have websites that are confusing and nearly impossible to navigate, their rates and fees hidden by dense industry jargon and misleading advertising. Who has the spare the time to sort through the choices spread out over all these different sites and companies?
