1. Contracts: Before, there were no contracts. You signed up or you didn’t. When it’s the only game in town, you have to play by their rules. Nowadays, you’ll see these ultra-fabulous rates bandied about but it’s only by carefully scrutinizing the fine print that you’ll discover those wonderful rates come with a one-year lock-down or other catches.
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 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.
