Lars Holze-Lentas

Beim Leitungsausbauprojekt Ganderkesee – Sankt Hülfe bin ich für die Planung und den Bau der Freileitung zuständig. Bei der TenneT arbeite ich bereits seit einigen Jahren als Projektleiter, so habe ich beispielsweise beim Leitungsausbauprojekt Dörpen West – Niederrhein mitgewirkt. Ich bin Vermessungsingenieur und habe mich auf Stromleitungen habe ich mich spezialisiert, weil ich die besondere Rolle der Stromversorgung in unserer Gesellschaft hochspannend finde: Ohne die Grundversorgung durch Strom würde unsere Gesellschaft nicht funktionieren. Deshalb finde ich es toll, durch meine Arbeit ein Stück weit dazu beizutragen, dass diese Grundversorgung mit Strom auch während und mit der Energiewende gesichert ist.
