smart4grid - a company of KoCoS Messtechnik AG

At smart4grid, we are convinced that the energy transition can only be successfully realised through innovative solutions in grid monitoring and management. Two experienced professors and a successful entrepreneur stand behind smart4grid, together we bring over half a century of experience in research and development in the field of digitalised energy systems. In the past, we have developed fundamental functions in the field of grid automation together with international partners from industry and operation based on measurement hardware established on the market and successfully implemented them in reference projects. Our concepts and solutions are well known and have proven themselves - now it is time to bring them into the grid at scale.

With smart4grid, we have created a secure, powerful and scalable platform for smart grid applications that makes it possible to master the challenges of the energy transition and shape a sustainable energy future.
