Thus, 87,600 MWh/year equals 87.6 GWh/year. So let's start at the beginning: Energy is a measure of how much fuel is contained within something, or used by something over a specific period of time. The watts aren't affected by how long the 100 W light bulb is running for A second, an hour, a day no difference so long as it's switched on it will be using 100 W of power. Focusing on trade journals covering construction and home topics, his work appears in online and print publications. Select the unit to convert from in the left box containing the list of units. Or you can instantly compare the average kW from last month with the average kW from yesterday and the average kW from the whole of last year. This energy metres squared, grams, moles, feet per second, and many more! Light bulbs are a simple example: if you have a 100 W light bulb you know that it will use 100 W of power when it's running (100 W of power being the same as 0.1 kW of power). Convert energy of megawatt hour (MWh) and gigawatt hours (GWh) units in reverse from gigawatt hours into megawatt hours. So to give you and idea of a GWh, Electrical energy requirement in Scotland is about 1 GWh every 20 minutes on average. 1 Reply Throwaway_43520 6 yr. ago From the models I've seen their resin is somewhere in the middle. Bzzz! You might hear the power that something is generating, or can generate, referred to as its "output". Use this page to learn how to convert between TWh and GWh. Energy is like distance. This is the maximum annual power production for your generator. For example, given half-hourly data for a month, the peak load or maximum demand could be defined as the half-hour period that had the highest average kW. molecular weight. But fortunately we're not writing this for physicists). Press question mark to learn the rest of the keyboard shortcuts. Once you've loaded some data into Energy Lens you can easily plot charts and calculate figures in units of kWh (energy) or in units of kW (average power), or a mixture of both. Niagara Falls, Ontario, Canada, Florida Power and Light Power Production Plant, Port Everglades, Florida. The power being used at an instant in time is measured in watts, or W. The amount of energy used over a certain period of time is known as watt-hours (Wh). It makes sense that cost should be calculated per kWh (not per kW), because cost is a cumulative thing the more energy you use, the more it costs. Examples of 1 TWh Please note that the following are separate for each network: The participant ID card identifies the appropriate channels for submitting claims and contacting us. Wind turbine capacity factor depends on location. kWh = kilowatt-hour For example, a 100 W light 10 kW is the rate at which the wind turbine can generate energy, not the amount of energy that it can generate in a certain period of time. if you find any missing units or errors. as English units, currency, and other data. Please enable Javascript to use If a kWh figure covers a day, we can only compare it fairly with other kWh figures that cover a day. You may also be looking 1 Gigawatt Hour to common energy units; 1 GWh = 3600000000000 joules (J) 1 GWh = 3600000000 kilojoules (kJ) 1 GWh = 860420650095.6 calories (cal) 1 GWh = 860420650.0956 kilocalories (kcal) 1 GWh = 2.2469385462308E+31 electron volt (eV) 1 GWh = 1000000000 watt hour (Wh) 1 GWh = 8.2573655700885E+29 atomic unit of energy (au) 1 GWh = 1 MW = 1,000 kW A watermill is one example of using this energy. If a kWh figure covers a week, we can only fairly compare it with other kWh figures that cover a week. What is the difference between electricity generation capacity and electricity generation? One kilowatt hour converted into gigawatt hour equals = 0.0000010 GWh 1 kWh = 0.0000010 GWh The first huge piece of the first major US offshore wind Australia's stunning Spring into green energy future Press J to jump to the feed. Whether it is a conversation about power plants, customer demand, new technologies, regulatory issues, or marketprices, industry insiders will assume you understand units. A megawatt hour (MWh) is one megawatt of electricity produced for one hour. Most discussions in the electric industry requirefluency in electric units. It's a bit like asking "how long does it take to travel 10 miles per hour?" Converter type: energy units First unit: The instantaneous power of most buildings varies constantly. On other hand, message server is a server that can relay/send/receive messages. At the simplest level cost is usually expressed in terms of /kWh or $/kWh or /kWh or p/kWh or c/kWh (or whatever-unit-of-currency-you-have per kWh). When describing the amount of electricity produced over a period of time, the units commonly used are megawatt-hours (MWh) and gigawatt-hours (GWh), where 1 GWh = 1,000 MWh. GWh is gigawatt-hours, which is a measure of energy. Create an account to follow your favorite communities and start taking part in conversations. Joules per second makes it obvious that power is the rate at which energy is being generated or used. The amount of energy that you used over a specific period of time is like the distance that you travelled over a specific period of time. Joules per second (J/s) is a nice, clear unit of power. Let's pretend we're working in /kWh To work out the total cost over a specific period, calculate the total number of kWh over that period, and multiply that by the /kWh. And they named this unit after James Watt, the Scottish inventor who had an important hand in the development of the steam engine. We can express quantities of these forms of energy in terms of kWh. What youre really asking is the difference between potential energy and potential. For both, its only differences that are physical meaningful (d Gigawatt hours per year (GWh/year) is a measure frequently used for electric generator output. And like how the electricity that runs a fan is converted into the motion of the fan blade (kinetic energy). In many ways average-kW figures are easier to work with than kWh figures. Similarly, capacity reflects the instantaneous ability to provide energy required to do work (such as generator capability to provide electricity, transmission capability to transmit electricity, etc.). When people talk about a particular biscuit containing 172 Calories, they're talking about the amount of energy contained within that biscuit. 1 MWh = 1,000 kWh Energy is power over time. Energy suppliers/utilities come up with complicated tariffs to define these rules. A 5 GW power plant operating at 100% output is continuously producing 5 GW. After one hour of operation, the plant will have produced 5 GWh (five g throughout a certain type of operation (e.g. GW is gigawatts. Residential and small commercial installations have smaller capacities, and describing them in megawatts is not practical, since the unit is too large. 1 GW = 1,000 MW. Similarly, you can express a measure of energy in joules, or Calories, or kWh, or BTU etc. That's double the average kW of a typical weekend, and that's bad because December 25th was a public holiday and the building was closed. 1 kW over a 30 minute period = 1 * 0.5 = 0.5 kWh (using kWh = kW * h, and 30 mins = 0.5 hours), Prices change over time. Convert GWh to GW Error: We couldn't find a conversion between GWh and GW Having trouble with a unit conversion? My brother's car does an average of 29. Demand and capacity are commonly measured in the following units: W = watt Following is the fundamental equation that connects energy and power. Power is energy per unit time. No! At the end of the day it's all just usable energy in different forms. The two are closely connected, but we'll get to that shortly. Simple. Gigawatt Conversions: GWW 1 GW = 1000000000 W. GWMW 1 GW = 1000 MW. symbols, abbreviations, or full names for units of length, That will give you the total cost in . The Calorie is a unit of energy And the joule (J) is a unit of energy And these aren't the only units of energy there's the BTU, the watt hour (Wh), the therm, and plenty of obscure units that you're unlikely to have heard of. And, provided we've got a gas or oil burner, we can easily make use of gas or oil. Having trouble with a unit conversion? From January 1st, 2017 to December 31st, 2017 it might have used 31,250 kWh. Average power works in the same way, but with energy instead of distance. Thanks, As we progress toward integrating the Cigna and GWH-Cigna networks, our goal is to strengthen the networks to offer more choice to our customers. Enter the value (for example, 15) into the left, Alternatively, you can enter the value into the right. gas or oil or wind) and turn it into another (e.g. For more information email us a [email protected] or call us at866.765.5432 x700. It's easy to become a participating health care professional in Cignas broad national network. Energy or usage reflects demand or capacity multiplied by the amount of time that demand or capacity is in use. If your generator capacity is 10 megawatts, it can produce 10 megawatts each hour, or 10 MWh. You might remember it from school: We can express this equation in terms of kW, kWh, and hours (h): You might also remember from school that equations can be rearranged: Given a value for any two of the following: average power (kW), total energy (kWh), hours (h), you should be able to use the formulae above to calculate the value of the third. power). Scale matters A gigawatt is a typical large nuke the Hoover dam is 2 gigawatt A large coal plant is typically 500 mw. (If at any point you'd like to thank us for our help in reducing headaches and embarrassment, please point your colleagues and website visitors towards this article so that it can help them too. Consider a laptop: at any one instant it might be using 50 W of power, or 30 W of power, or 43 W of power, or any similar such value. 2022 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. GWh = gigawatt-hour, 1 kWh = 1,000 Wh People often refer to power as the "load" or the "demand". Currently, electricity is generated by harvesting kinetic energy of flowing water of rivers, or potential energy of water in reservoirs. 172 Calories is equivalent to around 0.2 kWh. Question: Does something like this actually exist? A higher video resolution is logically better for analyzing and sifting the video footage. Our health plans are designed to motivate patients to use health care professionals in our network. One month you're paying. If, at any particular moment, everything in an office building is switched on, that office building might be using 42 kW of power. Or maybe that's just the average power of the office building on weekdays. That's 0 kW of instantaneous power. The higher a building's kW, the faster that building is using energy. Image courtesy of 123RF.com, Pickering Nuclear Generating Station, Ontario, Canada, Wind turbine at the Exhibition Place. For example: You can easily use these average-kW figures to compare the energy consumption of different periods and even different buildings (we use the term "energy consumption" loosely because really we're talking about average power, not energy). Compared to what exactly? 107.4 milliwatts per gram - Star produces 1.82 microwatts per gram through fusion Plutonium produces 1.94 milliwatts per Multiply the MWh figure from Step 1 by 8,760, the number of hours in a year. No surprises there. Average power, typically measured in kW, is a great way to look at the energy usage* of a building. conversion calculator for all types of measurement units. Deliver a MW of power for one hour, and you have a MWh of energy. Do the same for two hours and you have 2 MWh. One is a measure of instantaneous p You might also be interested in our other energy-related articles. You're Being Lied to About Electric Cars. On February 16th, 2018 a building might have used 95 kWh. There is only one difference: the element of time. My brother's car does an average of 41. And it's difficult to make fair comparisons between kWh figures unless they are all from periods of exactly the same length. Capacity factor is an average figure over some unit of time, usually a year. (A physicist might throw their arms up in disgust at how we've over-simplified one of the fundamentals of the universe. 0 W). If, at any particular moment, everything in the office building is switched off, that building should be using 0 kW of power. when driving to work you travelled at an average speed of 2.26 mph you might as well have walked). And figures of energy consumption are meaningless unless you know the length of the periods that they were measured over. Our biscuits contain a certain amount of energy 172 Calories or 0.2 kWh per biscuit. The power input in a heat engine is measured as MWt, and the output power obtained as electricity is measured as MWe. All Rights Reserved. across all the weekends on record); or. Probably the best option would be to eat the biscuit, but hopefully you get the general idea the biscuit contains energy that can be converted into different forms Electricity and other fuels supply energy in a form that we can use to run the equipment in our buildings. Energy can change form. kW) make many things more straightforward Power is the rate at which energy is generated or used. The GWH-Cigna identifier also appears on paper EOP documents and on EDI transactions. For helpful information about recent changes to ID cards, refer to the Guide to the GWH-Cigna Network. Show Megawatt Gigawatt Conversion Chart Instead. Well, the difference is really very simple. The only requirement is that you specify the correct units at the data-loading stage. But you can compare the figures like for like, without worrying about the details of the specific journeys that they were calculated from. It would be better to say that energy is power times time, not power over time. Whats the difference between GW-B5600 and GW-M5610U? Think about it: if you have 30-minute interval data with readings in kWh, but you treat those readings as if they are in kW (average kW, strictly speaking), everything that you calculate further on will be out by a factor of 2: i.e. When completed, the 10 GW wind farm will produce 47,790 GWh of clean energy annually and offset 23.8 million tonnes of carbon dioxide emissions equivalent to around 9 percent of Egypts current CO2 emissions. One is energy and the other is power, If you run x MW power for 1000 h you can express the energy in x GWh 50 GW =. Over the week starting April 9th, 2018 it might have used 550 kWh. To see what these units areand how they relate, keep reading below or watch the following video: Demand reflects the instantaneous amount of work required to perform the function desired (such as creating light or physical force, powering a microchip, etc.). This article has been adapted from an entry in Enerdynamics Energy Knowledgebase, which is an online resource of important terms and concepts explained simply and clearly. The occasional cost figure can be useful for showing to non-technical folks (everyone understands pounds and pence, dollars and cents), but cost figures aren't very good for accurate, in-depth analysis of energy-usage patterns (e.g. Watts are a pretty small unit of measure, and most households use thousands of watts - so instead of listing out all those zeros, you convert to kilowatts or megawatts. Toronto, Ontario, Canada, Tidal turbine at the Canada Science and Technology Museum, Ottawa, Niagara River near The William B. Rankine Generating Station, which was closed in 2009. The output will likely be in megawatts; a gigawatt is equal to 1,000 megawatts. There's a limit to how much useful stuff these things can generate, and that is expressed as the rate at which they can generate energy. Try doing a search , or posting to the forum. [an error occurred while processing this directive]. The building used 38 kW (on average) between 09:00 and 17:00 on Tuesday, December 25th, 2018. Which is, by definition, their power. The total electrical energy consumption of Scotland in 2012 was about 25,000 GWh, divide that by 365 in a year and we get 68.5 GWh per day and then by 24 hours in a day, 2.85 GWh. GWh is gigawatt-hours, which is a measure of energy. However, we can't immediately compare the efficiency of the building over each of those periods. The length of the time period doesn't really matter. 15 minutes is 0.25 hours, 30 minutes is 0.5 hours, a day is 24 hours, a week is 24 * 7 hours etc; a MW (megawatt) is 1000 kW and a kW is 0.001 MW; a MWh (megawatt hour) is 1000 kWh and a kWh is 0.001 MWh; and. GW = gigawatt. With this energy units pair converter, a difference between two energy units are calculated to work out their corresponding equivalent values. any other conversions between units that measure the same thing (like different units of energy, or different units of power, or different units of time) are widely available online. You can ask them to clarify, but it can be a little embarrassing if they don't understand the distinction in the first place Fortunately, when you hear someone talking about "power", or "load", or "demand", or "kW", you can usually tell from the context whether they're talking about average or instantaneous figures. The Watt ( W, kW, MW, GW) is a rate of use of energy. It is how rapidly you are using it at any given moment. You might be familiar with the idea o Energy units equivalents With this energy units pair Always refer to the information on the ID card for claim and contact information. That's a question that would only be asked by somebody that didn't understand what power was. To convert between these, you can use the following: 1 kW = 1,000 W Type in your own numbers in the form to convert the units! Put your laptop on standby and its instantaneous power will drop immediately. Electricity costs can depend on the time of the day, the day of the week, and the time of the year. Or, depending on the thing, and the person you're talking to, you might hear it called their "load" or their "demand", or you might just hear it referred to in terms of a W or kW value. Cigna works with doctors and other health care professionals to understand health care reform. contact us directly Well, thats an odd question. Suppose I asked you if I can increase 7,5 liters of water to 20 liters, what would you say? Or 7.5 grams of gold to 2 To get the rate of electricity production for the year of your generator, you need to know the output capacity of the generator, whether it is a wind turbine, geothermal or other. Given the right equipment we could turn the heat energy from the burning biscuit into electrical energy to run lights and fans and so on. Energy consumption expressed in terms of kWh doesn't often mean much unless you also know the length of the period that the kWh were measured over. The rate at which these things use energy is their power. Otherwise all your calculated figures can easily come out wrong. Quick conversion chart of TWh to GWh 1 TWh to GWh = 1000 GWh kWh is the unit of energy; it means kilowatt-hours, or 1000 watt-hours of You can also Solar obviously isn't going to be delivering any power at night, the capacity factor of solar usually is 25% over the course of a year. Or, if you find it useful, you could buy or recommend our Energy Lens software we really appreciate the customers that keep us in business.). Electric units include units of demand or capacity and units of energy or usage. You may also be looking for a GWkW 1 GW = 1000000 kW. To remove ambiguity we might call it "average power", or "load", or "demand". You are now familiar with the most common units used in the electric industry! Your instantaneous power is like your speed at a specific instant in time (e.g. This article explains more about the problems that arise if you compare the kWh used in one month with the kWh used in the next. Bill Brown has been a freelance writer for more than 14 years. For instance, a 15-watt light bulb used for 2 hours creates 15 watts X 2 hours = 30 watt-hours of usage. For some context, a gigawatt is equal to one billion watts. Try doing a But this is a distinction that people generally don't worry about when they're staring at an excessive energy bill and wondering how they can "use" less energy.). GW-B can link to G-Shock app, which mean it has bluetooth. How many kWh in 1 GWh? Some equipment is more complicated. Forgeworld resin is actually pretty high quality stuff, as far as resin goes. What does that mean? We could eat the biscuit to provide us with energy. Im planning to buy a square G-Shock this month and I came across this two models. If you're using 15-minute data, getting the units of the source data wrong can easily make all your calculations out by a factor of 4. The function can be achieved on the same server but better not. 1 Reply SunshineStarcraft 6 yr. ago Niagara Falls, Ontario, Canada, Pylons near Sir Adam Beck Hydroelectric Power Station. A So you might hear average power referred to as "average load", or "average demand". 49 GW =. (We don't need to care how many Saturdays and Sundays there were since March 2017.). It's the same for energy and power you need both, but usually one makes more sense than the other. 10 kW) or the total amount of energy used over a specified period (e.g. People sometimes use the word "mean" in place of "average", so you might also hear of "mean power", or "mean load", or "mean demand", or "mean kW". On long journeys my car does an average of 45 miles per gallon. Newbies to energy often try to use energy (kWh) for everything (sometimes calling it kW by accident), but more experienced folks tend to use power (kW) a lot more. Similarly, if your source 30-minute data has readings in kW, and you erroneously treat those readings as kWh, everything that you calculate further on will be twice what it should be. If you're working with energy on a regular basis, and you don't fully understand the difference between a kW and a kWh, we promise you that taking 20 minutes or so to fully understand the concepts explained in this article will save you many headaches in the future. It is a four-unit oil and gas power plant, Cooling towers of a nuclear power plant. Wrong question! That's 42 kW of instantaneous power. Following is a quick primer for those who want a basic understanding of key electric units. A gigawatt hour (GWh or GW.h) is a unit of electrical energy equal to 1000 megawatt hours (MWh) and equal to one billion (10^9) watt hours, 3.6 terajoules, or 3.41 billion British thermal units (Btu). The beauty of average-kW figures is that you can compare them fairly in an instant. 50000 MW. Energy calculations, and energy saving, become much easier when you understand the difference between a kW and a kWh. Though it only seems simple after you understand it. The distance between New York and London is fixed, but you can express that distance as 3,459 miles, or 5,567 km, or 18,265,315 feet etc. However, in reality, cost calculations are usually more complicated: All in all, if you're looking to reduce energy consumption it's usually much easier to spend most of your time working in units of kW and kWh. By convention the G and W are capitalized. If you try to monitor instantaneous power you get lost in the noise. Electricity tariffs often charge different rates depending on how many kWh you use. 2004-2017 Enerdynamics Corporation. Gigawatt hours, abbreviated as GWh, is a unit of energy representing one billion (1 000 000 000) watt hours and is equivalent to one million kilowatt hours. Lewiston, New York, United States, One food calorie of sugar, apple, banana and salami, NIST.gov. The watt (W) is a measure of power And the kilowatt (kW) is a measure of power too (one kW being 1000 watts). The following is a list of definitions relating to conversions between megawatts and gigawatts. date difference or Type in unit Alternatively, you might like to take a look at our Energy Lens software: 20062022 BizEE Software Contact Us | About Us | Privacy Policy, Energy Management the What, the Why, and the How, How to Use Energy Profiles to Find Energy Waste, 5 Rules for Monthly Energy Performance Tracking That Works, Energy Awareness Drop the Clichs and Make Your Campaign Hit Home, use Energy Lens to analyze energy data faster, frequently asked questions about Energy Lens. Just some bright spark decided that equations and whatnot would be simpler if power had its own unit (instead of being expressed using units of energy and time together). Really they're converting the energy into other forms (heat, motion etc. MW = megawatt Or we could burn the biscuit and turn it into heat energy. It doesn't make it quite so obvious what power means. Niagara Falls, Ontario, Canada, Robert Moses Niagara Hydroelectric Power Station. So if you have a hair straightener rated at 1000 W, and you use it for an hour, that's 1000 watt-hours, or 1 kWh. https://www.convertunits.com/contact/remove-some-ads.php, Error: We couldn't find a conversion between GWh and GW. What is a megawatt (MW)? The relationship between energy and power is a lot like the relationship between distance and speed: Both distance and speed are useful measures.
