 So this is a related topic as Dimitri already introduced. It is about the benefit and cost analysis of a wind turbine. So here we will go into a bit more details of things partly covered in Sebastian's presentation. So the cost-benefit analysis is essential to value of information analysis for the simple fact that we somehow need to account for the economics and in our value of information to see the benefit or the cost of one scenario compared to another or further scenarios. Playing big parts in this analysis are, of course, the financial circumstances, which could be the interest rate we need to discount, the future earnings we have to a known, so current value of money. There are other uncertain aspects like the future energy prices in terms of a power generation system like wind turbines. And of course, these economical systems are also influenced by different types of environments. So we can have subsidy schemes that may be changing. We can have different market fluctuations, new technologies emerging. The system might be sold. And all these things can be relatively simply modeled. But there are things that are quite uncertain in these models, at least if you are not an expert in these specific fields. So here we have some examples of values that could constitute such a model. So very important, first of all, are the basic investments, the capital expenditures. That is, in principle, the construction cost for such a wind turbine here expressed in euros per kilowatt. Then we have an interest rate, which is an assumption because we do not know the future. How will it develop? Here it is assumed to be 5%, which is a rather common value. And then of course, again, operational costs, which might also vary for the specific system you're looking at. Then here the capacity factor of 50% and availability of 90%. And of course, very important to know how much we can earn from the system, of course, is also its maximum output. One of the things that we have already observed very much is the change of energy prices. We have seen a strong increase of energy prices in the last decade, but then also just one and a half, two years ago, a sudden drop again due to the oil price drop. So this is also a big source of uncertainty we are looking at. So I will give you three different examples. We have a rather grim example with a energy price of just two and a half cents per kilowatt hour, or a decent or rather slightly higher price of 3.9 cents per kilowatt hour, and a quick analysis of the last 14 years has resulted in a third quanta value of the energy prices discounted again with 5% of 67.5 cents per kilowatt hour. So this is then the range you can see at the moment we had this as a not infrequent value of energy prices in the last one and a half decades, and at the moment we are somewhere in between here. Discounting, the other very uncertain factor in the model that is presented, has also a very strong effect on the benefit we can generate with such a turbine. So here you see in the graph the discount rate as it's changing over time with different interest rate. So you could basically assume this would be one monetary unit or just one without unit. And you see here as time progresses we have a decrease of value of this starting value. Or in other ways we can also use this to calculate the current value of future earnings. This is given here in this example. If you imagine you will receive 100 euro from a person in a year, you can calculate this way how much value this 100 euro in a year will have for you today. Simply by assuming a interest rate here 5% and then it would show you, OK, it is about 95% euro. So the three examples we are looking at are actually six. We are considering two different markets, the Danish energy market and the German energy market. The Danish subsidy scheme is based on a tender plan. So the successful bidder is guaranteed for 50,000 full load hours, a subsidy or a guaranteed price or guaranteed feed-in fee. And this depends on what the successful bidder said I want to have from you, what I want to have guaranteed. So it could be a rather courageous bid and says I just want to have 5 cents per kilowatt hour guaranteed or it could be a higher value. So here we have an assumption of a higher value. You see the red line is at 14.5 cents per kilowatt hour. Then we have two German models. These models will also change to a more Danish-like model in the future. But the current system is that the government has an initial subsidy phase with very high subsidies, either the 12-year-long phase, which guarantees 15.8 cents or a higher scheme that guarantees 19.8, 18.9. Not sure about that at the moment. And afterwards we have then a second subsidy phase up to 20 years that has a rate of 3.9 cents. So that's why you see these different steps. And this will also influence, of course, the profits that can be made with the produced energy. Here we see it, the profits we will earn. This is already the income from the energy produced, subtracted, or the costs subtracted from the income that is produced. So the operation costs have been taken out of this graph. And then we see a steep increase until this first kink in the graph. This is when the subsidy ends. And the gray line here, that is marking the capital expenditures. So this is after reaching this line, the system has generated overall profit. And here in the end you see six different lines. They diverge into the different price we have. So from the low price with just 25 euros per megawatt hour, sorry, the age is missing, up to 65.5. What is very important here to recognize is the influence of the energy price we see here on the lifetime extension. So it's also sensitive not only to the information I have about my system, how reliable it is in the end, and will I need to invest a lot of money to keep it going, but also of course how much money will I earn with it. And here we see different scenarios. In all these three scenarios we are making a profit. So this is the return over investment, the ratio of returned money over my initial investment. And we have values ranging from about 13% return to an increase over 10 years, only of 14%, 15%, just one or 2% more for the assumption of a very low energy price. With the slightly higher price we see already a big jump of 5%, 2%, and high energy prices we see an increase of almost 15%. So this has a big influence and is one of the big uncertain factors, how will the energy price develop? It can of course be that during the initial subsidy phase the energy prices are low and then they will increase and the operator is very happy about the situation or due to effects like currently the oil prices if this scheme continues the energy prices or the electricity prices might of course also be low and the spot market price at this shift here might be more in the lower area. So as I told you already this is a tool that can be almost immediately used. There's a spreadsheet available where you can, if you use this model just enter the numbers you need and it will generate the return of investment and costs you will have and profits. And it's also easily adjustable to similar cases. It can be transformed maybe to a bridge where you have a roll tolls in place instead of energy that is produced and of course other maintenance costs and investment costs. So the adjustment is relatively easy straightforward to other systems where maybe the uncertainties are lower. What would be very helpful from the network is some additional insight on the uncertain values in this model. At the moment to us it is quite unclear how to predict on a reliable basis or on an established basis the future energy prices. How can we maybe adjust the outlook we will achieve from this model with new information? I don't know on the action that OPEC might limit the oil production, that there will be an export embargo on an energy producing country or the interest rate. At the moment when we look at the banking markets, the interest rates there are negative actually. So banks lending money to other banks lose money by lending it. On the other hand of course we know that companies still make a profit. So where is the ideal way to establish a interest rate to discount for the earnings and spendings in such a model? Thank you very much.
