The Construction Site of Tomorrow: Results of 3 Years of Field-Testing Electric Excavators

“The Construction Site of Tomorrow” is a 3-year collaboration of a consortium of seven contractors, two knowledge institutes, and the construction machinery supplier on the deployment of heavy-duty electric excavators. The practical experiences of “The Construction Site of Tomorrow” have resulted in technical improvements of the machines, new insights about energy consumption in different use cases, experience with the deployment of the machines, and practicalities around charging the machines’ batteries in different situations. In this paper, we elaborate on the findings of the project, including the usability of the machines, their energy consumption, and total costs of ownership. This work has been coordinated by FIER Sustainable Mobility. The project was sponsored by the Netherlands Enterprise Agency.
