Electricity pricing (sometimes referred to as electricity tariff or the price of electricity) varies widely from country to country, and significantly from locality to locality within a particular country. Electricity prices are dependent on many factors, such as the price of power generation, government subsidies or taxes, local weather patterns, transmission and distribution infrastructure, and multi-tiered industry regulation. According to the U.S. Energy Information Administration (EIA), "Electricity prices generally reflect the cost to build, finance, maintain, and operate power plants and the electricity grid."
