Our take
As the world transitions to sustainable energy, millions of new wind energy systems are being integrated into power grids. As well as the number of new consumer solutions, such as electric charging stations is also rapidly increasing, and the integration of these new systems is putting a strain on distribution grids.
Envelio is a cloud-based smart grid platform providing a solution to this challenge. The Cologne-based company has developed the Intelligent Grid Platform (IGP), a software assistance system that transforms power grids into digital, flexible interactive smart grids. Through IGP grid operation management can be carried out digitally at a quicker, more cost-effective pace.
Born out of the Institute of High Voltage Technology at the RWTH Aachen, Envelio has since grown a steady customer base for itself and expanded on an international scale. Recognised as a clean-tech software company, Envelio is driving the change to sustainable energy.
