Data Collector
In the UK electricity system, a data collector (DC) is responsible for determining the amount of electricity supplied so that the customer can be correctly billed. Half-hourly For half-hourly metered supplies, the half-hourly data collector (HHDC) retrieves the energy consumption data from the meter and makes any necessary estimates. The half-hourly (HH) data is a history of the customer's electricity consumption for each half-hour period. Non-half-hourly For non-half-hourly metered supplies, the Non-Half-Hourly Data Collector (NHHDC) determines the consumption by calculating the advance (the difference between the last two meter reads); this is annualised to produce an Annual Advance (AA) and is the data the supplier will pay on. The NHHDC is also responsible determining the Estimated Annual Consumption (EAC), which is a forecast for a year ahead. The EAC is initially provided by the supplier, and thereafter forecast based on actual meter readings. Data from the Data Col ...

Electricity Sector In The United Kingdom
The United Kingdom has a National Grid that covers most of mainland Great Britain and several of the surrounding islands, as well as some connectivity to other countries. The electrical sector supplies power at 50 Hz AC, and ~240 volts is supplied to consumers. In 2020 the electricity sector's grid supply came from 55% low-carbon power (including 24.8% from wind, 17.2% nuclear power, 4.4% solar, 1.6% hydroelectricity, 6.5% biomass), 36.1% fossil fuelled power (almost all from natural gas), and 8.4% imports. Renewable power is showing strong growth, while fossil fuel generator use in general and coal use in particular is shrinking, with historically dominant coal generators now mainly being run in winter due to pollution and costs, and contributed just 1.6% of the supply in 2020. The use of electricity declined 9% from 2010 to 2017, attributed largely to a decline in industrial activity and a switch to more energy efficient lighting and appliances. By 2018 per capita elec ...

Electricity
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of p ...

Electricity Billing In The UK
In the United Kingdom, an electricity supplier is a retailer of electricity. For each supply point the supplier has to pay the various costs of transmission, distribution, meter operation, data collection, tax etc. The supplier then adds in energy costs and the supplier's own charge. Regulation of the charging of customers is covered by the industry regulator Ofgem. MSP and GSP MSP kWh is the amount of electricity consumed at the 'meter supply point', which is the customer's meter. GSP kWh is obtained by multiplying the MSP kWh by the Line Loss Factor (LLF, a figure > 1) to include the amount of electricity lost when it is conducted through the distribution network, from the 'grid supply point' to the customer's meter. Some kWh elements of the bill are charged at MSP and some at GSP. The LLF for a particular supply depends on the distribution network operator (DNO) and the supply's characteristics and the time and date (day of week, season etc.). The bill The consumer pays ...

Meter Point Administration Number
A Meter Point Administration Number, also known as MPAN, Supply Number or S-Number, is a 21-digit reference used in Great Britain to uniquely identify electricity supply points such as individual domestic residences. The system was introduced in 1998 to aid creation of a competitive environment for the electricity companies, and allows consumers to switch their supplier easily as well as simplifying administration. Although the name suggests that an MPAN refers to a particular meter, an MPAN can have several meters associated with it, or indeed none where it is an unmetered supply. A supply receiving power from the network operator (DNO) has an import MPAN, while generation and microgeneration projects feeding back into the DNO network are given export MPANs. The equivalent for gas supplies is the Meter Point Reference Number and the water/wastewater equivalent for non-household customers is the Supply Point ID. Structure An MPAN is commonly separated into two sections: the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electricity Meter
North American domestic analog electricity meter. Electricity meter with transparent plastic case (Israel) North American domestic electronic electricity meter An electricity meter, electric meter, electrical meter, energy meter, or kilowatt-hour meter is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device. Electric meter or energy meter measures the total power consumed over a time interval. Electric utilities use electric meters installed at customers' premises for billing and monitoring purposes. They are typically calibrated in billing units, the most common one being the kilowatt hour (''kWh''). They are usually read once each billing period. When energy savings during certain periods are desired, some meters may measure demand, the maximum use of power in some interval. "Time of day" metering allows electric rates to be changed during a day, to record usage during peak high-cost periods and of ...
