Powering Berlin TXL! Green Urban Energy will supply the Urban Tech Republic and the entire Berlin TXL project with climate-friendly energy in the future – thanks to the innovative LowEx grid. This low-temperature grid, which Green Urban Energy is currently working on, provides climate-friendly cooling and heating on a partnership-based energy marketplace. And so the energy concept of Berlin TXL will become a model for future neighborhood development. Green Urban Energy is backed by Berliner Stadtwerke and E.ON with its highly innovative concept for the Berlin TXL energy marketplace.
