Local Energysystems for Electrified Logistic Applications (LEELA)
Project Leela aims to increase understanding of how the energy supply for electric heavy vehicles can be secured at various logistics units as the introduction of these vehicles intensifies. The focus will be on designing the electrified logistics system at a local level to contribute to the transportation system's transition rate to fossil-free transport in a rapid, efficient, and inclusive manner. Additionally, the project will develop concepts that may be relevant for demonstration in a potential follow-up project. The project brings together relevant stakeholders to address these challenges.
Results
LEELA shows that the power capacity challenge can be addressed locally at the terminal by expanding on-site energy systems—using solar panels and battery storage—and by utilizing available resources more efficiently. The results pave the way for a faster and more sustainable electrification of the sector, without being constrained by grid operators’ long lead times.
The report provides more information on how the project was carried out, details about the modeling of the energy system, and insights into the various challenges faced by the project’s industry partners.

Power shortage threatens the electrification of the logistics sector – but local solutions and user flexibility point the way forward
Background
The significance of energy supply and the challenges related to it are becoming increasingly apparent as the introduction of electrified heavy-duty trucks accelerates. To meet the logistics system's needs and to ensure efficient vehicle utilization, charging is scheduled during times and at locations where the trucks are stationary, during reloading and parking. This creates significantly higher energy demands at terminals and, in some cases, very high power peaks. Consequently, this places greater demands on power availability from the grid and increases costs in terms of grid connection fees and power tariffs.
With the current 'first come, first served' principle regarding available grid capacity and with widespread electrification in society, access to power quickly becomes scarce. Addressing this issue through grid expansion and reinforcement is time-consuming and resource-intensive. Furthermore, logistics terminals historically have been established without stringent requirements for power availability from the grid, which can further complicate efforts to link logistics and electrical systems through the electrification of trucks.
Given that power availability from the grid is both scarce and cost-driving, local solutions in the form of energy storage and electricity production can become important facilitators for the rapid electrification of trucks. These local energy solutions can also contribute to supporting the existing grid and relieving the expected high expansion rate of the grid. In this way, they can contribute to the broader electrification of our society."
