What is a kWh? kW and kWh explained | OVO Energy
Discuss KW and KVA? in the Industrial Electrician Talk area at . by the computer (watts) it bears no relation to the power supplied to the circuit. You can convert kVA into kW, or kW into kVA if you know what the power factor of the machine is. Electrical efficiency is measured as a power. Power Calculators for quick electrical generator power consumption, sizing, and unit conversion. Convert kW to kVA, kVA to kW, voltage, kW to HP, and more to.
A CHP plant is an installation where there is simultaneous generation of usable heat normally for space heating and power usually electricity in a single process. Combined Heat and Power CHP A gas fired power station where the waste heat is used in manufacturing or district heating. Communication Charge The monthly fee payable by a customer, which covers the collection of half hourly data by the meter operator.
This can be billed direct by the MOP or passed on through the current supplier.
Connection Agreement Agreement between client and the local distribution company for example Central Networks in the Midlands setting out the terms and conditions with which each are bound concerning the provision and use of the connection. Current Transformer These are used to measure a load on a supply.
Data Aggregator The organisation appointed to aggregate the meter-reading data received from the appointed Data Collectors and forward it to suppliers. Data Collector The organisation responsible for collecting, processing and validating the meter reading data, who then passes the information to the Data Aggregator. De-energisation The interruption of supply, so that electricity cannot flow from the network to the premises.
Demand The requirement for power. Demand Site Management The planning, implementation, and monitoring of activities designed to encourage consumers to modify patterns of electricity usage, including the timing and level of electricity demand. Disconnection The permanent removal of the meter, cabling and service from the property once it is established that a supply will not be required in the future. This permanently removes the MPAN. Distribution System The local wires, transformers, substations and other equipment used to distribute and deliver energy to consumers.
DUoS Distribution Use of System The charges incurred for distributing electricity across the local area system to the supplied premises. Energy Watch A non-governmental body set up to safeguard the interests of energy users.

The white paper sets four new goals for energy policy: European Emissions Trading Scheme The EU ETS is one of the policies being introduced across Europe to tackle emissions of carbon dioxide and other greenhouse gases and combat the serious threat of climate change.
The scheme will commence on 1 January The phase runs from and the second phase will run from to coincide with the first Kyoto Commitment Period. Further 5-year periods are expected subsequently.
This can be three times the contracted pence per kVa rate. Extra High Voltage 22, volts or higher voltage Feasibility Study A methodology for identifying where and how energy is used on a site within core processes and then making recommendations for reducing usage and or eliminating waste.
Firm Gas Gas supplied to a customer on a guaranteed basis, without interruption. Fixed Charge A monthly of quarterly charge levied by the supplier and is in addition to the standing charge. Forwards Contract An agreement to buy electricity from another party at a specified time in the future at a specified price with money changing hands at the delivery date.
Fossil Fuel An energy source formed in the Earths crust from decayed organic material. The common fossil fuels are oil, coal, and natural gas. Futures Contract Similar to a forwards contract these are normally trade through an exchange on standard contract terms with profits or losses calculated and paid daily. Gate Closure In relation to a settlement period, the time 3. It defines the moment when bilateral contracting ends and the Balancing Mechanism for each associated trading period begins.
Generation This covers the production of electricity at power stations. At present the main fuels used are gas, nuclear and coal, although there is now a growing use of renewable forms of energy, such as wind power, the burning of gas from landfill and waste incineration.
Gigawatt GW A unit of power equal to 1 billion watts; 1 million kilowatts, or 1, megawatts. Gigawatt-hour GWh A unit of energy equal to million kilowatt-hours. Grid Supply Point A point of supply from the national transmission system to the local system of the distribution network operator. The data is used for invoicing, tendering and reporting purposes.
How to convert VA to Watts and KVA to Kilowatts
Imbalance A situation where there is a difference between the amount of power produced and the amount of electricity contracted or sold. Interconnector A connection or link between power systems that enables them to draw on each others' reserve capacity in time of need. Interruptible Gas Gas supplied to a customer whose site has an alternate fuel source, on the basis that the supply might be interrupted for a specified period.
The Integrated Pollution and Control IPPC directive means companies face new aspects for consideration, controls to put in place and an increase in work required to obtain and comply with environmental permits. The resultant effect of the active kW and reactive kVAr power is the total power measured in kVa.
Kilowatt kW A standard unit of electrical power equal to 1, watts, or to energy consumption at a rate of 1, joules per second. Kilowatt-hour kWh A unit of energy consumption.

A typical home uses around 3, kWh of electricity per annum. Kyoto Agreement An international Agreement signed by countries agreeing to limit or reduce their global emissions. Load The amount of electric power delivered or required at any specific point or points on an electrical system. The requirement originates at the energy-consuming equipment of the customer.
Load Factor Measures the relationship between unit consumption and maximum demand and is the percentage capacity utilisation figure of a site's power consumption. To calculate load factor take the total number of units of consumption, divide by the maximum demand, divide by the number of hours in the period, and multiply by Load Management The process of shifting the use of electricity from periods of high demand to periods of lower demand, when the cost of electricity is usually lower.
LV Low Voltage, normally at or Volts. Managed Load The fixed energy base load of the total curve. This can be purchased either all at once or step-by-step. Maximum Demand The highest average demand in kW or Kva occurring in a half hour period. Megawatt MW The equivalent to one thousand kilowatts kW. Meter Point Reference Number A unique reference number identifying each meter and used in the preparation of supply tenders. It is not intended to give you advice on your personal financial circumstances.

When you get your electricity and gas bills, what do you look at? You may check the meter readings to make sure they match the ones on your meter. If you know what a kilowatt hour is, it can help you understand: How your energy supplier works out your bills Why some appliances use much more gas or electricity than others - and how much individual appliances use Why you should turn appliances off at the wall to save energy costs, and not just leave them on standby You can then use that information to help you monitor your gas and electricity use, cut costs and lower your bills.
So what exactly is a kilowatt hour? It is simply a unit of measurement that equals the amount of energy you would use if you kept a 1, watt appliance running for an hour: So if you switched on a watt light bulb, it would take 10 hours to rack up 1 kWh of energy.
Or a 2, watt appliance would use 1 kWh in just half an hour. While a 50 watt item could stay on for 20 hours before it used 1 kWh. What else takes around 1 kilowatt hour? A kilowatt is simply 1, watts, which is a measure of power. So, for example, the 10, watt electric shower in the top bullet point above could also be called a 10 kilowatt shower.
