To achieve the established environmental goals, a significant transformation is requiredin the Swedish transport sector. This includes a shift away from fossil fuels and a greateremphasis on electrifying a larger portion of the vehicle fleet. The goal of this study is toevaluate the impact on the local distribution grid when integrating a high power chargeradjacent to a mobile battery storage system. In addition an investigation of the energyflows was conducted to assess the continuous operations of charger, battery and electricitygrid. The introduction of high power loads leads to higher power peaks in the system,which may affect the stability with respect to the voltages, currents and harmonics in thegrid. This thesis was conducted in collaboration with Gävle Energi AB, which is a local energycompany that is active in the area around Gävle. In total two models were created inorder to simulate both the energy flows and grid stability. The first model was conductedin MATLAB and used to evaluate the energy flows for the scenarios of low and high load.The second model was conducted in OpenDSS to evaluate the grid stability for a total of6 scenarios. The scenarios are as follows: the initial electricity grid, the grid with a highpower charger integrated and the grid with both a high power charger and a solar parkintegrated, for both low and high load cases. The results of the study showed that high power loads affected the local electricity gridmost during low load since it entailed high load peaks during that period. The effect ofintegrating a high power charger in a grid with radial grid topology is that the voltageis reduced and harmonics increased in loads connected to the same node. The effect ofintegrating a solar park instead increases the voltage and reduces the harmonics in loadsconnected to the same node. The energy flow evaluation showed that the battery hadthe potential to be continuously used for both the low and high load cases. However,during low load the battery had the potential to provide frequency regulating services tomaximize the income.

The electrification of heavy transport is considered a solution to climate change. Today, electrification is challenged by high investment costs for vehicles and charging, which hampers the conversion. The purpose is to investigate what investment risks occur when creating a stationary charging hub by focusing on three different charging possibilities (private, semi-public, and public) to examine the differences between them. The study is a case study with the study object Stockholm South, which is considered to be a future logistics area. The study is based on literature, documents, and interviews with actors linked to the study object. Moreover, to identify potential investment risks the study conducts a life cycle cost analysis of a stationary charging hub. The conducted interviews identified that several actors are positive to enable a charging hub, but are challenged by high investment costs, uncertainties regarding electricity network capacity, and future prospects linked to the technological development of electric trucks and charging technology. Moreover, the interviews also identified opportunities such as financial support, potential market advantages of being one of the firsts on the market, and contribution to a sustainable transport sector. The results of the cost analysis show that a stationary charging hub for heavy goods transport entails high investments and operating costs, which are affected by future aspects such as electricity prices, electricity networks, technology development, and utilisation rate. In addition, the choice of closed or open charging hub has an impact on the total cost. The analysis of the results indicates that collaboration between the involved actors can facilitate several of the identified challenges and risks. The study contributes to expanding the empirical data on stationary charging infrastructure for heavy freight transport. In addition, the study contributes with a cost analysis for a charging station that can provide inspiration and a basis for future investments. The theoretical contribution mainly concerns how new technologies in ecosystem theory are handled in relation to collaboration and business models. / Elektrifieringen av tunga transporter anses vara en lösning på klimatförändringarna. Elektrifieringen utmanas idag av höga investeringskostnader för fordon och laddning, vilket hämmar omställningen. Syftet med studien är att undersöka vilka investeringsrisker som uppstår vid skapandet av en stationär laddhubb genom att fokusera på tre olika laddningsmöjligheter (privat, semi-publik och publik) för att undersöka skillnaderna mellan dem. Studien är en fallstudie där studieobjektet är Stockholm Syd som anses vara ett framtida logistikområde. Studien baseras på litteratur, dokument och intervjuer med aktörer kopplat till studieobjektet. För att kunna identifiera investeringsriskerna har en livscykelkostnadsanalys gjorts för en stationär laddhubb. De genomförda intervjuerna identifierade att flera aktörer är positiva till att skapa en ladd hubbmen att utmaningarna framförallt ligger i höga investeringskostnader, osäkerheter angående elnätskapacitet och framtidsutsikter kopplat till den teknologiska utvecklingen av ellastbilar och laddningsteknik. Däremot identifieras även möjligheter så som finansiella stöd, potentiella marknadsfördelar med att vara en av de första på marknaden och att bidra till en hållbar utveckling av transportsektorn. Resultatet av kostnadsanalysen visar att en stationär laddhubb för tunga godstransporter medför höga investerings- och operationskostnader som påverkas av framtida aspekter så som elpris, elnät, teknikutveckling samt utnyttjandegrad. Dessutom har val av stängd eller öppen laddstation inverkan på kostnaderna. Analys av resultatet tyder på att samarbete mellan involverade aktörer kan underlätta flera av de identifierade utmaningarna och riskerna. Studien bidrar till en utökad empiri kring stationär laddinfrastruktur för tunga godstransporter. Dessutom bidrar studien med en kostnadsanalys för en laddstation som kan ge inspiration och underlag för framtida investeringar. Det teoretiska bidraget berör främst hur nya tekniker ses på inom ekosystemsteorin i förhållande till samarbete och affärsmodeller.
