It ensures that if x kW of geothermal heating, cooling or domestic hot water is installed, this installed power can be used throughout the whole simulation period. An example of a resulting temperature profile after the optimisation for power is given below.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"361\" src=\"https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Example-of-an-hourly-temperature-profile-1-1024x361.png\" alt=\"\" class=\"wp-image-5512\" srcset=\"https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Example-of-an-hourly-temperature-profile-1-1024x361.png 1024w, https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Example-of-an-hourly-temperature-profile-1-300x106.png 300w, https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Example-of-an-hourly-temperature-profile-1-18x6.png 18w, https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Example-of-an-hourly-temperature-profile-1-767x270.png 767w, https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Example-of-an-hourly-temperature-profile-1.png 1278w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Example of an hourly load profile optimised for the maximum geothermal power. <\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">As can be seen in the temperature profile above, the fluid temperature touches both temperature limits, indicating that there is no more geothermal potential for power left.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The advantage of this algorithm is that it makes the overall design of the hybrid system quite straightforward. If the building has, for example, a heating demand of 100 kW and the optimisation tells you that you can get 60 kW of geothermal power during the whole simulation period, the hybrid technology can simply be designed to deliver the remaining 40 kW, avoiding any oversizing of the system.<\/p>\n\n\n\n<div class=\"caution\"><p>It is important to note that the statement that the optimised power is always available during the simulation period assumes that the <strong>load profile stays the same<\/strong>. If you design your hybrid system according to a certain load profile, the algorithm indeed ensures that the calculated power is always available in the simulation period. When this profile changes, this can no longer be ensured.<\/p><p>In fact, this is exactly the same reasoning as when designing any geothermal system with an hourly load: for a specific hourly distribution, the temperature limits can be maintained, while another load profile could result in an undersized borefield.<\/p><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Optimisation algorithm<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Since the design of hybrid geothermal systems is not trivial and can sometimes give surprising results, it is important to understand the underlying optimisation algorithm in depth. The algorithmic reasoning is explained below.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Start with an hourly heating, cooling (and optionally domestic hot water) demand profile and a certain fixed borefield design.<\/li>\n\n\n\n<li>Calculate the hourly temperature profile with 100% of the building demand being delivered by the geothermal borefield.<\/li>\n\n\n\n<li>Check whether:\n<ol class=\"wp-block-list\">\n<li>The minimum fluid temperature is below the set threshold.<br>If it is, the extraction power is too high, so it should be reduced by limiting either the heating or the domestic hot water demand. Depending on which one you want to reduce first, the heating or the domestic hot water demand will be reduced by x% for the entire simulation.<br>If the minimum fluid temperature is above the threshold, the current heating and domestic hot water demand can be provided by the geothermal borefield.<\/li>\n\n\n\n<li>The maximum fluid temperature is higher than the set threshold.<br>If it is, the injection power is too high, meaning that the cooling power should be reduced by x% for the entire simulation.<br>If the maximum fluid temperature is below the threshold, the borefield can handle the injection, and no changes are necessary.<\/li>\n<\/ol>\n<\/li>\n\n\n\n<li>If both temperatures from step (3) are within the limits, the geothermal and hybrid loads are determined, and the algorithm goes to step (7). If at least one of the temperature thresholds is crossed, the algorithm continues with step (5).<\/li>\n\n\n\n<li>Recalculate the hourly load for the borefield using the new maximum peak powers for heating, cooling (and domestic hot water) as determined in step (3). Redirect the power or energy that cannot be handled by the borefield to the hybrid technology.<\/li>\n\n\n\n<li>Recalculate the hourly temperature profile and return to step (3).<\/li>\n\n\n\n<li>Done.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">To put it graphically, the algorithm searches for the maximum heating, cooling and domestic hot water power in the load-duration curve and tops off the load at this power. Everything below this maximum power can be delivered by the borefield, while the unhatched area should be delivered by something else.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"1024\" height=\"361\" src=\"https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Load-duration-curve-1-1024x361.png\" alt=\"Load-duration curve of the hybrid system after the optimisation for power.\" class=\"wp-image-5510\" srcset=\"https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Load-duration-curve-1-1024x361.png 1024w, https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Load-duration-curve-1-300x106.png 300w, https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Load-duration-curve-1-767x270.png 767w, https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Load-duration-curve-1-18x6.png 18w, https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Load-duration-curve-1.png 1278w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Load-duration curve of the hybrid system after the optimisation for power.<\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">In the profile above, it can be seen that the maximum power for heating is capped at around 20 kW and for cooling at around 45 kW, while domestic hot water can be delivered entirely by the GSHP with a maximum power of 30 kW.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Example in GHEtool<\/h2>\n\n\n\n<div class=\"hint\">If you want to follow along with the example below, the required documents can be downloaded at the end of this chapter.<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">In order to illustrate the power of this method, a residential building with just under 50 kW in heating and 100 kW in cooling, with yearly demands of 92.5 MWh and 24 MWh respectively, will be discussed. Furthermore, an hourly domestic hot water demand is also considered, with a peak power of 30 kW and a yearly domestic hot water demand of 60 MWh.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The ground heat exchanger is a double DN32 U-tube, with 25 v\/v% of MPG and a variable flow rate based on a temperature difference of 3\u00b0C across the heat pump. The minimum and maximum average fluid temperatures are 0\u00b0C and 17\u00b0C over a period of 40 years.<\/p>\n\n\n\n<div class=\"caution\">Whenever you are working with hybrid systems in GHEtool, it is important to think twice about your flow rate. These algorithms change the resulting geothermal load and therefore, probably, also the resulting flow rate. In order to avoid mistakes, it could be better to work with a variable flow rate based on a constant temperature difference. When you do have a fixed-speed pump, please check the resulting flow rate afterwards by also calculating the hydraulics.<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">When 100% of the load should be delivered by the borefield, a borefield with 40 boreholes of 100 m deep is required. Unfortunately, this space (or budget) is not available for this project, and the question is what geothermal share you can get with at most 30 boreholes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To start, a borefield of 5&#215;5 boreholes of 100 m deep is considered. As can be expected, this borefield size is too small, as is visible in the temperature profile above, where both the minimum and the maximum fluid temperature thresholds are crossed. It is clear that in this case a hybrid system is required.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"744\" height=\"400\" src=\"https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Too-small.png\" alt=\"Temperature profile for a 5x5 borefield without any hybridisation.\" class=\"wp-image-5563\" srcset=\"https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Too-small.png 744w, https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Too-small-300x161.png 300w, https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Too-small-18x10.png 18w\" sizes=\"(max-width: 744px) 100vw, 744px\" \/><figcaption class=\"wp-element-caption\">Temperature profile for a 5&#215;5 borefield without any hybridisation.<\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">When this hybrid system is designed and optimised for the maximum power, the following result is obtained.<\/p>\n\n\n\n<div class=\"note\">In the first optimisation, it was selected that the heating demand should be reduced first, so that the domestic hot water can stay on the geothermal borefield for as long as possible.<\/div>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"766\" height=\"338\" src=\"https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Geothermal-share-5x5-heating.png\" alt=\"Geothermal share for a hybrid system optimised for power and a borefield of 5x5 boreholes.\" class=\"wp-image-5513\" style=\"width:766px;height:auto\" srcset=\"https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Geothermal-share-5x5-heating.png 766w, https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Geothermal-share-5x5-heating-300x132.png 300w, https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Geothermal-share-5x5-heating-18x8.png 18w\" sizes=\"(max-width: 766px) 100vw, 766px\" \/><figcaption class=\"wp-element-caption\">Geothermal share for a hybrid system optimised for power and a borefield of 5&#215;5 boreholes.<\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">In the case of 5&#215;5 boreholes, all the domestic hot water can indeed still be provided by the geothermal system, as well as 89.5% of the entire heating demand, with a maximum power of 25 kW.

This is because simply reducing the domestic hot water demand to 0 kW is not enough to keep the fluid temperatures during extraction between the limits. Therefore, a further reduction of the heating power is required. The share of geothermal cooling is 78.4%. The resulting temperature profile, which looks very similar to the result for the optimisation with 5&#215;5 boreholes, is shown below.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"744\" height=\"400\" src=\"https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Temperature-profile-4x4-dhw.png\" alt=\"Hourly temperature profile after optimisation for power for a borefield of 4x4 boreholes.\" class=\"wp-image-5518\" srcset=\"https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Temperature-profile-4x4-dhw.png 744w, https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Temperature-profile-4x4-dhw-300x161.png 300w, https:\/\/ghetool.eu\/wp-content\/uploads\/2026\/10\/Temperature-profile-4x4-dhw-18x10.png 18w\" sizes=\"(max-width: 744px) 100vw, 744px\" \/><figcaption class=\"wp-element-caption\">Hourly temperature profile after optimisation for power for a borefield of 4&#215;4 boreholes.<\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">Looking at the temperature profile above, there is still no geothermal potential for power left, since the fluid temperature touches both the maximum and minimum fluid temperature limits. However, there is still quite some potential for energy remaining, more specifically for heating in the first years and for cooling in the later years. This will be discussed in the next chapter, which covers the optimisation of hybrid systems for maximum energy.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This chapter introduced the first methodology to design a hybrid geothermal system for maximum power. By reducing the maximum peak power in heating, domestic hot water and\/or cooling in the load-duration curve, a load profile can be obtained such that the resulting temperature profile always stays within the temperature limits.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The advantage of the optimisation for the maximum power is that it does not oversize the entire hybrid system. The geothermal power it calculates is namely available during the whole simulation period, so the hybrid system can simply be sized to deliver whatever the geothermal system cannot handle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The downside of this method is that it leaves some geothermal potential for energy behind. This will be discussed in the <a href=\"https:\/\/ghetool.eu\/course\/optimise-hybrid-system-for-maximum-energy\/\">next chapter<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">References<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Peere, W.
