EF = Supplied Electricity Explanation: EF should mean "Energia Fornita", which is differently paid according to time bands (usually 7 a.m. to 7 p.m. and 7 p.m. to 7 a.m.) |

electronic multiple tariff power meter Explanation: penso che sia utile precisare che misura la potenza elettrica Multiple tariff (variable rate) meters Electricity retailers may wish to charge customers different tariffs at different times of the day to better reflect the costs of generation and transmission. Since it is typically not cost effective to store significant amounts of electricity during a period of low demand for use during a period of high demand, costs will vary significantly depending on the time of day. Low cost generation capacity (baseload) such as nuclear can take many hours to start, meaning a surplus in times of low demand, whereas high cost but flexible generating capacity (such as gas turbines) must be kept available to respond at a moment's notice (spinning reserve) to peak demand, perhaps being used for a few minutes per day, which is very expensive. Some multiple tariff meters use different tariffs for different amounts of demand. These are usually industrial meters -------------------------------------------------- Note added at 1 ora (2011-09-28 16:41:14 GMT) -------------------------------------------------- EF= potenza elettrica fornita |
