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.
The problem is that across Africa, the vast majority of the power utilities are effectively bankrupt. Another World Bank study (pdf) on African Utilities shows that only two of the 39 African utilities surveyed, in the Seychelles and Uganda, were able to generate enough cash to cover both their operating costs and capital expenditures necessary to invest in the maintenance and expansion of the grid. In fact, only 19 of the 39 companies were able to generate enough cash to cover their day-to-day operating costs. It means the rest were not even able to pay everyday costs, like salaries, in full.
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.
In Houston, 0% of people have switched to a plan that has some renewable energy component to it. Another 0% have switched to a plan that is partially renewable, while 0% have switched to a plan that powers homes completely by renewable electricity. This of course means that 100% of people have remained on a plan powered by traditional sources of electricity such as coal or nuclear power.
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?
