Want to save up to 45% on your electric bill? Details of the ComEd Hourly Pricing Program
hi today im going to be going over the,comed hourly pricing program i,have found it the best way and the,easiest way to save money on my electric,bill,beyond any other program ive tried,including third party providers,so today im going to go over an,overview of the program,and basically go over the key elements,of the program and then also go through,some of my bill examples of my personal,bill,and show you varying amounts of power,used,and how much money is saved,on those varying different different,types of bills,so lets start with the the summary of,the program,so again summary of the common pricing,program its designed and implemented,actually by elevate energy,comed works with them for this program,each hour of the day calculates the,average hourly price,of energy this information is provided,by pjm they report the wholesale energy,prices to comed,and then the smart meter collects the,power data,um with and correlates that with the,time of day,uh and then comment then takes that,information,correlates it with the wholesale,information,uh and um and basically thats what they,use to add up your,bill i found with no change in my power,usage behavior at all,i have saved money you can certainly,save more money by changing your power,usage,and how you use your power and what time,of day you use your power so in other,words if you did laundry,um you know uh basically in the evening,you know eight oclock nine oclock ten,oclock at night um,instead of doing it at like four oclock,in the afternoon especially during the,summer,you can certainly save some money by,moving certain things,to certain power producing things to,a time of day that has lower prices but,again i have not done that we have just,continued to use power the way,um that we were using power before,comet recommends to consider moving uh,to this program if you have 350,uh kilowatt hours or more,um but i will show you through some,examples that,um i think you can have less than that,actually and still save money on this,program,uh and actually back when i started to,use this program,um it was called residential real time,pricing they since it changed the,program name to the hourly pricing,program,um i should also mention also that,ameren has a similar type of program,that elevate energy also designed for,them,i believe its similar to this program,but you would want to investigate that,for yourself,so comed provides a pricing dashboard,that the day before they will tell you,what they think the price of energy is,going to be,based on the information they have from,pjm,and then what the actual price of energy,is based upon,the usage on the network the demand on,the network,as you can see theyre generally pretty,close but theyre never,very rarely are exactly what what is,predicted,but it gives you an idea of when the,peak times are,going to be during the day so you can,view this,on their web portal on the hourly,pricing web portal,and it is provided real time,so lets go over some sample bills,so on the left hand side is the standard,bill and on the right hand side,is actually my november bill and all my,charges,the delivery and the taxes are exactly,the same,nothing changes between the two bills,all of the magic happens,in the electric supply services section,so lets go over each of those line by,line,so if you look at the electrical sorry,electricity supply,charge you can see on the standard it,has a,standard rate its the amount of power,that you use,times the rate and thats what comes up,with the total,if you look on the hourly all you see,is the amount of power used okay so,the rate because its not a standard,rate and it varies,they dont put the rate in that,accumulated,total is based upon what the smart meter,plus the,actual data from pjm um,and the power used during depending when,the power was used thats how they,calculate that total,the next charge actually on the,on the hourly is the capacity charge and,that,is a key difference between the two,programs and that is,the usually the biggest question um that,people have,is that capacity charge how is it,calculated how does it affect things,ill be going over that in detail as far,as,how to determine your own capacity,charge and such,and ill be doing that in just a few,moments so then the transmission,services charge,the theres two they both have a,standard rate,but the transmission services charge on,both programs,is different so that amount will be,different um its actually lower on the,hourly than,it is on the sample residential bill,part of the reason for that is because,on the hourly the miscellaneous,procurement component charge,is included in the standard rate,transmission services charge,then below that you have the purchased,electricity adjustment and that is,different,between the two programs but generally,balance balances,out between the two one month one might,be higher than the other,next month is the opposite so in my,examples i just made them the same since,i didnt have,exactly what the purchase electricity,adjustment was for that month,for the standard rate so like i said i,balanced it out,its pretty much lost in the noise and,youll see that um when we go to look at,the bills,and then i also have solar so i do have,some some net metering credits,um from my solar production um but again,that kind of gets lost in the noise um,and again when we go over the bills ill,ill show you that as well so again as i,mentioned before the delivery services,charges and the taxes are exactly the,same so we will not be touching on those,because they are exactly the same,between the two bills,so as i mentioned the capacity charges,where,where people have a lot of questions so,the capacity charge,is a factor of four different elements,only one of them you have control over,and thats the capacity,plc that factor is based upon,the hi the highest usage or the highest,demand,on the network and what your usage was,during those highest demand,events um believe its four or five,events that they measure,and based upon those events is,how your capacity plc is determined,so for instance um you know if,you are cooling your house,and you notice through an alarm theres,ways you can set alarms and things like,that for when the power,cost of power goes up if you see the,cost of power go up and you turn,you turn up your thermostat instead of,charge you know cooling your home to 74,degrees you decide youre going to cool,it to 80 degrees,um you know so that you lessen your your,demand on the network,that will help your capacity plc,for the following year so your capacity,plc,is determined the summer prior to,when it goes into effect so for instance,that june,20th to may 21st uh sorry,june of 2020 to may of 2021,um thats my current capacity charge,that capacity charge was determined by,what i used over the summer of 2019,so it does take a while for that to go,into effect,so what i used this past summer in 2020,um is will go into effect on june of,2021,this year so because i did put in solar,in september of 2019 past when,the capacity charge was determined but,so this was my first summer,that i had solar those high,demand periods i had solar helping me,out so i had much lower demand youll,see next year,you could see that that capacity plc,is about a third of what it was um uh,this year,so um but again were not going to be,looking at that,most people arent going to have solar,that have this program but,this is basically how its determined,now,this ill provide links to all this,information in the description,but this the link down below um the,secure.commed.com,my account blah blah blah that,will take you to,um the page where you can get all of,this information your scaling factor,your forecast pool requirement monthly,capacity charge along with,your capacity plc um,as long as you have a smart meter if you,dont have a smart meter then you,wouldnt have that,they wouldnt be able to determine this,information but most people do have,smart meters at this point,so that is ho
Project: Introduction to ComEd Real-Time Pricing Program and The Next Project
Im actually really excited because what,I want to talk about is hourly pricing,program I believe its called and this,is specifically for electricity pricing,so its for your electricity utility,most of the United States uses a fixed,price per kilowatt hour of service and,so theres a national average and Ill,write this in blue just to give a little,dot here the national average and this,fluctuates,is actually around 14 cents per,kilowatt-hour if you used fixed price,programs now I lived in the Pacific,Northwest for a short period of time in,Washington actually near Seattle and,this in I know theres various,exceptions to this but this is the,national average there are areas in the,United States where I think in Seattle,its mostly hydroelectric so they,basically make almost more energy than,they need so they export a lot of it and,the cost per kilowatt hour is way less,than 14 cents its somewhere I think on,the order of like four to five cents but,for most people again the average,nationally is around fourteen cents per,kilowatt hour and its important to,understand what that actually breaks,down to it Im gonna bring out a heavily,redacted comment bill this is my comment,bill do a pretty good job they did a,revamp of their bill I think a couple,years ago which really helps clarify,what youre paying for so theres three,pieces the two big pieces are the supply,and this is the actual they even have a,little little infographics here which is,really kind of helpful the generation of,the electricity and your charges for,that and then the delivery of that,thats as the infographic shows thats,the high-tension wires the Transformers,switching gear and all that stuff that,gets the power from where its generated,to your outlet well to your house not to,the outlet inside your house but to the,meter,there are two charges here plus theres,some taxes and fees but were gonna not,really consider myself with the taxes,and fees but rather the supply into,delivery this supply generally speaking,for most users in the United States no,matter who supplies their energy is a,fixed its a fixed charge per kilowatt,hour but if you look at your bill youd,probably see something up here that,would show mine says residential hourly,single which means its a non-static,rate I forget Ill put it in the lower,third what the what the term would be,for if youre just on a standard rate I,think its a standard rate or something,like that that indicates that youre,paying the same amount for your energy,no matter what time of day youre using,it and so for most people if your energy,usage is quite low lets say you use,less than three roughly 300 to 400,kilowatt hours per month if youre in an,area where your national average is,somewhere around 14 cents per kilowatt,hour thats fine youre probably youre,probably going to get the energy as,cheaply as you possibly can get it,because you have to factor in the supply,plus delivery and a little bit of taxes,and fees but if your energy usage goes,above that threshold of about 350,kilowatt hours I actually have a,spreadsheet that I did to kind of figure,out what the break-even point was using,hourly pricing program and I can,actually do another video actually where,I walk through that but basically the,short of it is that around 350 kilowatt,hours is the break-even point for the,ComEd hourly pricing program and so what,is it what does this actually mean and,its its pretty simple at its core if,you look at the fixed price program you,have three cost bins so Im going to,break them out here you have supply,delivery and taxes the supply is roughly,about on the national average eight to,nine cents per kilowatt-hour the,delivery is about five to six cents and,a taxes account for about one to maybe,two cents on the high end depending on,your municipality etc so the hourly,pricing program focuses on this bucket,they focus on the supply portion of the,bucket the delivery in the taxes they,pretty much take the same but the supply,portion can be changed such that youre,not using a fixed rate no matter what,time of day are using the energy and the,reality is that when utility companies,are generating energy theres a market,for that energy even though you dont,you cant see it and its not a tangible,thing theres a market for that energy,and so during the day at four oclock on,a hot summer afternoon theres high,demand and limited supply so the cost,goes up but other times a day where,maybe its not ninety five degrees,outside and its eight or nine oclock,at night theres very little demand so,the cost electricity plummets and so,what you end up with is a situation that,looks more like this and the the,technical term is called Bosch which,Ill put in the what it means but its,updated every five minutes,it was basically is the market rate,pricing for electricity so the hourly,pricing program as the name implies,doesnt focus on even those updates,every five minutes youre not being,billed for whatever the prices as it,fluctuates every five minutes you get,billed based on what the pricing is per,hour if I were to draw a little graph,here to compare the two if we were,looking at a typical day Im going to,put on the x-axis here dollars per well,cost per kilowatt hour this is not a,super accurate graph but just to give,the visual indication of the differences,between the two programs,looking at 12:00 a.m. 12:00 p.m. and,then 12:00 a.m. the next day and lets,say were in April its gonna be summer,or approaching summer if you had the,national average youre just using your,regular utility your cost per kilowatt,hour would just be a flat line across,the entire day no matter what time of,day youre using energy its going to be,basically 14 cents or a kilowatt hour,but if you were using instead the besch,or hourly pricing program as ComEd sells,it so to speak Im gonna draw a couple,tick marks in here so I can get a guide,when the peak times generally are for,for summer and adding em to this since I,started doing it at one point is that,the cost per kilowatt hour fluctuates so,you might see something along the lines,of this make sure I actually can draw,this without,so you might see a line that looks more,like this throughout the day and the,peak here during the day might be even,on pretty warm days 85 to 90 degrees,outside you might see let me draw the,celli over to here about 810 cents,well just say 10 cents per,kilowatt-hour so this is at the peak of,everybodys coming home turning on their,air conditioning,it might peak a little bit earlier,around 4 oclock but well say 6 p.m.,everybodys coming home it peaks at that,time so wow thats thats you know,thats pretty high its 10 cents per,kilowatt hour thats approaching this 14,cents but you might notice that thats,really only during that peak time of the,day so if you were to integrate if you,were to basically sum across this entire,thing the the 14 cents per kilowatt hour,for a given amount of usage the same,usage pattern you would have just one,rectangle of this is how much youre,going to pay whereas the area under this,is much smaller and so for most of the,day 12 a.m. to say lets say 12 p.m. if,you have your refrigerator turning on,cooking or whatever earlier in the,morning this might be closer to draw,right here around 2.5 to 4 cents per,kilowatt hour,much lower than this and way lower than,the national average so you can start to,see that if you look at this program the,hourly pricing program if you do a,little bit of shifting of when youre,using various high demand appliances,like your air conditioner let me do it,draw a line here high demand basically,meaning high power so your AC dryer,washing machines if you dont have gas,appliances you have electric appliances,instead then that can include many,things including your range oven it can,be your microwave I guess it doesnt,matter whether or not your gas or,electric its a microwave will the dryer,definitely fits electric so definitely,if its electric if its gas theres,still a motor runni

Energy Options
At ComEd, the health and safety of our customers, employees, and communities are our top priorities., As part of this commitment, we are closely monitoring developments related to the coronavirus,pandemic and taking the appropriate precautions. Because social distancing protocols are being,followed while filming this video, I’m now removing my mask so that I can speak directly,to you. Hi, I’m here today to talk about a few of,the different energy options available to ComEd customers. Some of these options offer,bill credits, based on your energy use. Others offer different energy supply rates, depending,on what time of day you’re using energy. The one thing all these energy options have,in common, is that they can help you save money and reduce carbon emissions that may,contribute to global warming.,First, I’d like to go over the options for our customers who are considering going solar.,Whether you’re a renter or a homeowner, there’ s a solar option for you.,Here are some solar facts for you to…reflect on.,We may not live in the sunniest state, but solar works in Illinois! There’s plenty,of sunlight to power your private solar energy system and provide you benefits of solar energy.,But what is a private solar energy system?,A private solar energy system is when you have solar panels installed at your home or,business, usually on the roof. The solar panels, composed of photovoltaic cells, convert sunlight,into energy. They even produce energy on cloudy days, by using sunlight that passes through,the clouds.,With a private solar energy system, you can receive credits on your energy bill when your,solar panels produce more energy than you use.,These credits are called Net Metering credits. What is Net Metering?,Net Metering measures the net amount of energy you use from the smart grid, meaning, the,amount of energy we deliver to you minus the excess amount you send back to the smart grid.,With Net Metering, you’re only charged for the net amount of energy you use during each,billing period. And, if you use less energy than your solar panels produce, you can receive,credits on your bill. But what if you use more energy than your,solar panels produce?,Don’t worry. Since you’re still connected to the grid, ComEd will still deliver energy,to you, so that you can continue to enjoy uninterrupted power, even if you run out of,solar energy. Still wondering if private solar is right,for you? Then try our interactive solar calculator,at ComEd.com/Solar. This free online tool pulls a satellite image of your rooftop to,estimate: the upfront cost of installing solar panels, the investment tax credits you can,receive on the federal and state level after installing them, plus how long it may take,for your private solar energy system to pay for itself. Just type in your home address,to get started. Ready for the next step? Then visit ComEd.com/Solar,and select “Private Solar”, and then “Getting Started”. There we outline the step-by-step,process for customer ready to purchase and install a private solar energy system on their,property. One question I get all the time is “Does,ComEd sell or install solar panels, or can they recommend someone who does?”,No. While ComEd is a trusted source for information about solar energy, we don’t sell solar,energy or related products; nor do we guarantee savings. Beware of companies that may be misrepresenting,themselves as ComEd. Unfortunately, it happens, so keep your guard up and don’t get scammed.,If you are ready to buy and install solar panels on your property, you can reach out,to a solar contractor. An ICC certified solar contractor can answer any questions you may,have and provide you a thorough evaluation of your property and can provide you a quote,on your private solar options. We have a full list of ICC certified solar,contractors, plus tips to help you find the right contractor at ComEd.com/Solar. Just,select “Private Solar”, then “Getting Started”. There you’ll find instructions,under the “Working With a Contractor” section.,But what if you want to go solar, but private solar isn’t right for you? Maybe you’re,a renter, so you’re not able to install solar panels on the roof, or your roof has,too much shade, or you just don’t want to install solar panels on your property, for,financial or other reasons. Then you can still benefit from solar energy,through Community Solar!,A Community Solar project is a “farm” of solar panels that’s owned and operated,by a Community Solar Developer and is not located at your property. Energy generated,by these farms flows to the energy grid to become part of the overall energy supply.,Homes and businesses can earn bill credits by subscribing to a Community Solar Project.,Enjoy the benefits of solar energy without having solar panels on your property.,To learn more about Community Solar, visit ComEd.com/Solar then select “Community Solar”.,Still in the dark about solar? Then Visit ComEd.com/Solar to explore all your solar,options, frequently asked questions, step by step guides, and a variety of resources,to see if solar is right for you. ComEd also offers several energy options that,either offer you credits on your bill, or special rates, depending on when you’re,using energy.,These are called “Demand Response” programs. They’re designed to help you shift your,energy use from periods of high demand, to periods of lower demand. Why? Because by shifting,your energy use you could save money, and you’ll help reduce energy demand during,peak times when the use of costly, less efficient generation facilities is often needed. In,this way, you’ll help reduce the release of emissions that may contribute to global,warming and thereby help protect the environment for future generations!,Let’s move on to the first program. If you’re a homeowner and you have central,air conditioning, you can enroll in AC Cycling! With AC Cycling, you can earn up to $40 in,bill credits each summer! This program helps reduce peak energy demand,during the hottest days of the summer. How does it work? Using a direct load control,switch installed at your home, ComEd can cycle your air conditioning compressor off and on,during the hottest days of summer. The compressor includes the part of your AC system that uses,the most energy to cool the air. But don’t worry. Your air conditioner is,not shut off completely. Only the compressor turns off during an AC Cycling event. Your,system’s fan will still be circulating air. Then while the compressor cycles off, your,fan stays on to circulate already cooled air, keeping your home comfortable.,Now I know what you’re thinking. “Will I notice a change in the temperature inside,my house when my air conditioner is cycled?” Don’t sweat it! Customers who participate,generally notice little difference in their comfort level.,Depending on which option you choose, you can receive either five or ten dollars in,bill credits a month, for a max total of up to $40 in bill credits each summer! And it’s,free to enroll! So, visit ComEd.com/ACCycling to see what,option is right for you. Enroll today to save all summer long!,AC Cycling is great because once you sign up, you’re guaranteed to receive bill credits,each summer without having to do anything. The switch controlling your AC compressor,does all the work, helping reduce your carbon footprint.,But what if you don’t want ComEd controlling your AC compressor, but you still want to,help reduce your carbon footprint while receiving bill credits for it?,Then good news! We have a different summer savings program called Peak Time Savings.,With Peak Time Savings, you’re in control! Program participants receive bill credits,for voluntarily using less energy than they normally would, during certain hours while,energy demand is at its highest, such as during the hottest days of summer when most air conditioners,are on, stores are open, and factories are running.,That’s why Peak Time Savings rewards customers with bill credits if they use less energy,than

This is Why Most Freelancers Hate Hourly Pricing
whats up telling my freelancers and,creators out there this is nathan with,another episode of freelance jumpstart,TV and in this episode were going to,talk about hourly pricing I remember,some time ago in my younger days around,the ages of 13 and 14 I was looking for,a job I found out I was best to get a,job at the local McDonalds that was,close to my neighborhood so I applied,and at the young age of 13 I got hired,to be honest I was just happy to be,working the fact that I was actually,able to make any type of income at that,age while all my peers were at summer,camp was cool so I stayed there and,worked there a total of about four and a,half years and through that time I,learned a lot of things I felt like it,was great the fact that I always ate at,McDonalds and I got to work here its,just for like the perfect marriage of,two things not only do I get paid but I,can eat auto free me down as food I want,so the first year I work that I was just,getting the hang of things and the next,year I just expanded my skills so I did,everything from take orders at the front,counter then I also learned how to cook,in the grill and make everything I learn,how to make lunch I learn how to make,breakfast to learn how to make dinner I,learned how to restock the store I,learned how to report inventory on,things that were low or missing or,things we werent accounted for i,learned how to open the store i learned,how to close the store i learned how to,work in the drive through which is,completely different from working up,front and i learned how to clean up,everything so pretty much any job I,could learn in the store I learned it,seeing how all those different skills,work together fit me well because Im a,learner I like to learn the different,aspects of a job and then apply my,skills in the area in which I had the,most affinity or i just showed to be,best at so it just worked well for me,and i also realized that not only was it,a good thing to know these skills but,its really good to understand to do,them well because there are certain,people who caught on to things better,than others you know there were some,people who only stayed in the grill,because they were not good at cashiering,they were not good at customer service,they were not good anything,so they only stayed in the grill or they,only stayed in the drive-thru because,they didnt have to have face-to-face,interaction with people so but for me I,was versatile I learned many different,things I became so versatile to the team,I remember being in high school and they,wanted to promote me to manager they,wanted to promote a high school kid to,manage all these other adults that I,worked with because they saw how,versatile I was of course at the time I,was getting paid a little bit more than,minimum wage and as a middle schooler,and then a high schooler that seemed,like you know a lot of money to me and,at the time you know compared to my,friends who are making zero that was,actually very good and it was fitting,for me for that time period there was,something about getting paid by the hour,that I noticed when I was younger and I,didnt really like I didnt really like,the fact that I was trading my time for,payment because my time is not a good,measurement of how valuable I am or how,effective I am if I was at the front,counter taking orders and I was good at,customer service and I was able to get,you know 10 people through the line in,five minutes while my coworker was able,to get to people through the line and,they messed up in order why are we,getting paid the same thing it was then,that I realized being paid by the hour,was not the best evaluation and or,appreciation of the value that I brought,to the team sure you know maybe I might,have been getting paid more but how much,more ten cents more an hour twenty cents,more an hour a dollar more how do you,really weigh that in comparing two,different peoples efficiency levels I,share that story to realize a point,thats still true today in the world of,business and freelancing theres nothing,evil about getting paid by the hour,however is that the best method to use,to value your time at least for me when,I was younger and I saw that I felt,penalized because the more efficient I,got at my job the faster i got at my job,it really didnt benefit me anything and,I was getting penalized for working,better quicker or smarter I tell that,whole backstory to bring this to a point,right here in which if youre a,freelancer,rate of a consultant you probably had a,job in the past in which you were paid,by the hour now theres nothing wrong,with that but its a pretty standard,thing to do you charge people for their,time and weve gotten used to it I know,a lot of times when I work with clients,Im asked two questions either how much,do you charge flat fee or you know what,is your hourly rate those are the things,that Im asked up front and everyones,familiar with it the first point in,which I brought up in the story as,relates to our league pricing is youre,not necessarily rewarded for working,faster or efficiently so if you find a,way to do it better smarter if something,used to take you four hours but youve,gotten quicker and efficiency or you,learn how to do it better and you do it,in two hours you get less money not only,do you get less money but it becomes,more difficult to create a win-win for,the client as well as you you want to,work on and be rewarded for your time,but they also dont want to pay as much,so you have to try to balance between,the two and figure out what works best,when it comes time to raising your rate,if youre doing hourly pricing then you,want to raise your hourly fee but a,question may come up or people may,really start paying attention to the,actual hourly fee you said so maybe,youre charging fifty dollars an hour,and you will raise it to 75 100 but you,want to make more money because youre,getting more efficient so you know what,Im going to charge 350 an hour or Im,gonna charge a thousand and our people,will start looking at that and say,thats too high of an hourly price,because theyre really comparing you to,everyone elses hourly fee in their,minds so theyll come a point to where,you want to raise your rates but people,start paying attention to that number,when it gets too hot just to follow up,with the last point I just made also you,open yourself up to comparisons so if,someone says I charge 75 an hour and,they say I charge 80 people start,looking at well you know I dont know,how long its going to take but who,should I go with you know theyre,similarly priced which one is better it,doesnt necessarily represent the value,you bring to the table sure you need to,have a portfolio sure you need to tell,them what you can do but when its only,really price then people start paying,attention and comparing you based on,price who knows is the one hundred,dollar an hour person better than the,fifty dollar an hour person thats,definitely something to think about but,you open yourself up to more comparisons,sometimes when youre working under an,hourly price you really feel like an,employee it may take your mind back to,those days where you were trading time,for money and also the client may start,looking over your shoulder and see are,you really spending time efficiently,maybe something that took you you know,two hours last month this month you,learn how to do it better and it only,takes you 30 minutes but then the next,month you had ran into some difficulties,and it took you two hours again the,client may start looking and saying why,is this fluctuating point of time are,you really being efficient and it can,become a point of discussion and,clarification between you and the client,but really they shouldnt even be paying,attention to your time the focus should,be on did you complete the project and,did you do a good job at it not how,efficiently are using your hours that,brings me to another point which is what,is actually billable what can you,actually build for in my

Hourly Pricing and Day-Ahead Dispatch Setting in Brazil: the DESSEM Model
will introduce our speaker who is here,with us but uh,reliable were gonna first attempt his,video,and the speakers carlos enrique medeiros,de saboya,uh he is a civil engineer and holds a,masters degree in optimization with,focus in,uh large-scale combinatorial,optimization from the computing and,systems engineering program,at the federal university of rio de,janeiro since 2002,he has been with sapari which is the,brazilian electric energy research,center in rio de janeiro,and he works on mathematical programming,uh,projects with applications in energy,systems,so he will talk today about early,pricing and they had dispatch setting,in brazil with the decem model,and now i will attempt to play his video,and now i will share the screen,and,can someone confirm that they see the um,presentation of carlos,[Music],its not playing the audio engine,sorry audio also its no its not,pointy audio its not playing the audio,no uh when youre sharing your screen,when youre selecting your screen you,want to share,you have an option at the bottom to,enable to,share the computers sounds,[Music],share a computer sound got it,and try it you check that it should work,i am from september,energy research,and im going to present the paper,already pricing and they ahead,dispatch setting in brazil the same,model,in brazil since 2000 the weekly,hydrothermal dispatch,has been centrally coordinated by iso,with the optimization tools,new av and the comp developed by sapel,based on two-hour dynamic program and,the market price,are setting by the market operation,operation,in weekly time steps the model the same,has been developed by since 2000,and in 2017 has begun its validation,process to provide the optimal,hydrothermal dispatch,for the day ahead in half an hour time,steps,and the early market prices in this work,we are we present the main features,of this model in the practical aspects,such as the solution approach,that made possible its also used by the,brazilian iso,since january 2020,here we can see the brazilian generation,mix,that shows the hydro-dominated,characteristics of brazil,actually the hydropower plants still,keep responding for a round,of 70 percent of the total styling,capacity,and we can see also an increasing,participation of integrity,sources,brazil has a large-scale system,predominantly hydro,with stochastic inflows to hazards,and long distance between generation,source and load,in this figure we can realize that,operation the system,is as complex as to operate the whole,whole european,electrical system,in this diagram we can see the total,amount of hydropower plants,throughout the holy country coupled in,cascades,that are centrally dispatched by the,brazilian iso,the chain of optimization and simulation,models developed by cepel,and validated by the government,institution and most of private electric,companies,is officially used in the hydro thermal,power generation plane of brazil,to dispatch the system and set market,price price,among the others government planning,activities,in the center restructuring of this,chain of models are the model,new wave devoted to long-term operation,planning,using stochastic dual dynamic program,the model of the comp,devoted to medium-term operation,planning,using determinish vendor decomposition,and the model the same devoted to,operates the electricity in,early base that employs branch and cut,together with specific,feasibility pump and local branch,approaches,[Music],these three main models work in an,integrated,form the new wave is running at the,beginning of each month,to build a course to go function to,model the comp,that is running at each week and also,builds acoustical function to model the,same,this led is last one as running at each,day to provide the early dispatch,and spot price this time we continue,framework,among these models we call the holding,horizon,application,the main objective of the hydrothermal,coordination,problem solved by the same is to,minimize the thermal generation cost,in the water value in the reservoirs,coming from the coastal,function from model the comp the model,takes into account a detailing model,order of,hydropower plants in cascade the,modeling of,thermo-power plants considering unit,committing aspects,they intimidate generation technologies,like indian solar power,inside a dc flow network in an early,time step,[Music],the cost information of thermopower,plants comes,explicitly from the generation cost,and they start up in shutdown cost as,well,for hydropower plants it comes from the,water value,that is a function of the hazardous,volumes,and the efficience of the hydro hydro,plants,available at each bunch of operation,finally the intermediate,technologies like wing have no,generation cost and the model can decide,to use it,as long as allowed by the daily wind,forecast,[Music],the same model considers the power,balance,in each system area that is a set of,electric buses,and represents the many electric regions,of brazil,the generation technologies are plugged,in each specific bus,that are linked together through,electric lines in the,brazilian iso operation each considers,the first day in a half an hour time,step,in the following days in aggregated,hours time steps that are coupled with,the cost to go,function come from the comp at the end,of the week,in model the same the efficience of,hydropower plants as a function of the,water heads,that is also a nonlinear function of,turbine in inspired water,the so-called hydroproduction function,is therefore,considered through a piecewise linear,approximation in four,dimensions,the operation of the couple hydropower,plants,is modeling in a detailed form that,includes pumping stations,feeling of dead volumes channels between,receptors,modern of the river sections evaporation,has evolved multiple uses of water,fluid control constraints among others,due to the time steps in periods of,hours the water volume discharged in a,hydropower plant,may not be available in the subsequent,plant in the nest period,since in some cascades the water can,spend days traveling,in the model the river wrote as model,used water propagation,curves which between hezevers in that,introduced in the model a more complex,coupling,because a plant can be copper with its,subsequent,one in several periods of time,the thermal unit community modeling,employs classical constraints,such as minimal generation minimal up,and down times,startup and shutdown costs and wrapping,constraints,it also considers the startup,trajectories from the new to minimum,generation vector,as well as the shutdown trajectories,between the minimum generation,to the new value,the operation of psycho-combined,demobility plans,was considered through the concept of,conversation configuration modes,each unit physically represents an,integrated operation,among real units of guns and steam,turbines this detailed retail and,representation,is important since there is in brazil,thermal combined plants with high,capacity,around of 1.5 gigawatts,finally it was moderate the possibility,of transitions between,units in the following example after,unity represents a gas turbine its,minimal,its minimum there is a transition to an,unity represent a combining operation,between gas and steam,without the need you need to first,follow the shutdown trajectory,of the first one this model was based in,approach from literature,but some new concepts was considered and,moderate with,the use of binary control variables,[Music],the gc network is considered without,explicitly represents the phase angles,in the model,after optimize the problem the,injections are applied in the,corresponding buses to solve the dc flow,that gives us the electric flow in the,lines if any line,is violated a new a new constraint is,included and the model is running,again until no more violations in line,limits being fined,into this concept the model considers,line flow limits constraints ramp,constraints,online flows and power transmission,losses,[Music],i
Project: Hourly Pricing Smart Thermostat Build – Part I
what I have here is a,Raspberry Pi wireless Raspberry Pi zero,Wireless so this is the zero with Wi-Fi,on board and Bluetooth which is just,awesome it makes this proof of concept,which I had the idea for for about seven,years,I,started executing it,creating certain pieces of it for a,thermostat just to kind of it was a fun,little project to create a thermostat,using a,St micro-st m8 it was an 8-bit,microcontroller it was the cheapest,development board about a decade ago,with thing was eight bucks now you can,get a full fledged computer basically,for 10 bucks anyways it did the state,machine and did a bunch of stuff for,sensing temperature and humidity and,figuring out like whats the comfort,level and should I run the heat share on,the air conditioner tested it a few,times theres some pictures I think Ive,yeah Ill put some pictures up of what,it looked like and it worked well had a,2 by 16 display,but then it was trying to get it to,interface with hourly pricing what we,have here is this thing is just its,just waiting right now for me to ssh,back into it ok i need to reboot it,actually really quickly so youre gonna,see go back through its power on cycle,and do some stuff with the lights,the old raspberry PIs had just a,plethora of lights this is a Raspberry,Pi model B I believe that had a whole,bunch of lights for what is that hundred,mag on the Ethernet port,link,FDX Santee acts,like its packet transfer power and okay,or maybe this is the disk axis I forget,but bunch of lights and the Raspberry Pi,zero has one light which is its fine,because its nice and minimal its the,tiny little package that its all in but,this bonnet that sits over it is,actually it obscures the light so youre,watching it to see if its actually,doing anything and I think now it is it,is ready it is ready now cool oh,its pretty quick now were going to,team ox,and I need to go to route,rooks not Python in his Python,there it go,so execute it itll do,itll do some initialization,you see the light cycle really quick,just a light test there it goes and it,begins running and then the display will,come on and so right now a couple things,are happening one as you can see in the,screen grab that it is starting the RTP,monitor so it goes and every five,minutes it goes out to the RTP site and,uses the API to making a request to get,the current cost of electricity so this,is the current cost right now,now theres some,details that Ill get into in the next,video I just want to go over kind of,whats going on here now about what that,means but for right now lets say that,this is the current cost of electricity,and what the,Python script does with that what Ive,wrote to do with this value is assign it,to a color its this simple if else–if,structure for if the cost electricity is,really low then light up the blue light,like less than two point right now lets,think less than two point two cents per,kilowatt hour itll add the blue light,meaning its a blue light special go and,use as much electricity as youd like,typically it sits in the green which is,about two point five to four and a half,thats that range I was talking about in,the previous video if you go above four,and a half hour below six and a half,then the amber light comes on and if you,go above,six-and-a-half then the red light comes,on,and so,in addition theres a bunch of every so,often the API server doesnt want to,respond sometimes so that so much error,handling that needed to be implemented,to initialize some weights and then,retries and then like any other good API,implementation theyre doing you know,your call throttling so Im not just,trying to hit a whole bunch of time to,try to get the update but it will try at,at a rate of one try every five minutes,if it cant get something at five,minutes then it retries again after one,minute because you want to keep this,updated and,if its not updated in this and that,server goes down which it has gone down,like one time in eight months for about,maybe a half an hour and you want to,indicate to the user hey I dont know,what the pricing is yeah youre on your,own its the wild wild west you know,so theres that the other piece is the,outdoor temperature thats a recent,thing that I added just before I started,making this video its knowing what the,outside temperature is and outside,humidity is especially as we approach,summer to get an idea of what whats the,heat index what does it feel like,outside and how does that translate to,comfort inside and what the potential,cost impact will be when the outside,temperature is high because when the,outside temperature is high or the heat,index is high people get hot they want,to be cool so theyll turn the,air-conditioning down and the cost goes,up so it helps give more insight as to,whats going on here with that that,phenomenon is this agent this thing all,the time its not exposed to the,Internet the intent really is to never,have anything exposed except for things,that it makes calls to and then when it,does security updates and things like,that the idea for this project is to,really make this be as privacy oriented,as possible there are no microphones,mounted on this haha,as well as you know it really being just,about you having the control over what,youre spending your your resources on,and so this gives you more insight and,better visual indication of like oh what,is what is cost for lectricity something,it is very abstract you dont really,notice it until you look at electric,bill you go oh my electric bills $100,this month why well this Ive noticed,and my wife has noticed that it helps,get a very quick visual indication of,what is going on so the other thing,thats built in is is aged into it from,inside sight so I have a static IP but,just in case the IP changes I included,that which is some just some example,code that I was playing around with and,then I also have Im gonna hit it one,more time here so you can see it theres,also the last update so the last update,is important so it tells you its not,the current time its the its from the,RTP server the RTP servers API that,return it gives you it includes the last,time it was updated I dont think I,mentioned it but the weather data is,being provided by the dark sky API I,originally wanted to use the Weather,Underground API but they were acquired,by IBM and became the was the weather,company Ill put it up somewhere and the,weather company put all of the weather,API functionality behind a paywall so,thats unfortunate I mean if it helps,keep Weather Underground around its,fine but it kind of sucks for,developers like myself that just wanted,a good reliable,source of outside weather without having,to go put a weather station outside just,to get temperature and humidity I might,want more things later I might implement,my own outdoor temperature sensor and,weather station later but for right now,I just want this so the dark sky API and,Ill put a link to it below allows you,to,for free make a thousand calls to the,API day which Im updating it five,every five minutes unless I manually,refresh it so thats 12 times an hour,and its about you know thats what 144,288 times a day and I might actually,throttle that down even even more as it,gets like in low demand times where we,dont really care about the outside,temperature it could be ten minutes,between updates or whatever but Im,nowhere near 1,000 per day so it works,the next little piece I might touch on,is so what are the next big pieces that,Ill be introducing in future videos and,they involve taking this which right now,theres no way for this thing to control,anything in the outside world or take,any input from the inte from the inside,to make any sort of decisions on to,whether or not to run HVAC thats the,big next piece I described in a previous,video so we need two things one we need,relays to,be driven by this thing to control the,thermostat wires that are on the are on,the four wire system coming in from the,furnace controller which I will describe,in a f
