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]
The average home in the U.S. consumes 897 kilowatt hours (kWh) of electricity per month. Bills vary by state and region, as cost per kWh differs. To estimate average energy bills, multiply the average home’s electricity usage (897 kWh) by the cost per kWh in your state for that month. For example, the average cost per kWh in July for Colorado homes was 12.67 cents, which amounts to an average bill of about $113.65 (12.67 cents x 897 kWh) that month.

Texas electricity deregulation has given millions of Houston residents and businesses the power to choose the cheapest electricity rate. According to ERCOT, over 92% of Texas homes and businesses who live in deregulated areas have switched electric companies since deregulation began in 2002. Even though electric choice in Texas has been hugely successful for energy savings, customers are still confused by the options, terminology, and overall process of switching electric providers.
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]
But competition didn't necessarily end up cutting prices, according to the report. One contributing factor is confusion among customers as they try to choose among scores of retail electricity providers and the overwhelming variation of plans, leading many to just stick with familiar companies rather than look for better deals, according to the Texas Coalition for Affordable Power .

Technology that now allows smaller quantities of power to be generated closer to the end-users at prices not too much higher than grid-based power are undermining those economies of scale. More efficient turbines, for example, allow large power users like cement plants and petrochemical factories to come off the grid. Today the limiting factor for large companies to come off the grid often isn’t the efficiency of the power generation technology, but the lack of easy availability of fuel, such as gas or coal to power these turbines Even this problem is being solved by innovations like mini-liquefied natural gas projects.
