Given our expertise in carrying out large roll-out projects in all project phases, we are the ideal partner for conversion to smart metering, which enables the creation of so-called “smart grids”.

It is essential for the comprehensive use of smart meters to build the network for the additional transfer of data and thereby facilitate smooth transfers. Efficient generation and storing of electricity in the system also play a crucial role.

Our experts in energy and communications technology work hand in hand and combine their decades of experience in both sectors. You can rely on EQOS Energie’s in-depth experience for the energy technology sector and the construction of mobile and fixed network locations for your smart metering projects!
