Edge computing is a new paradigm that relocates cloud data processing to its source, reducing latency and energy consumption. This new form of distributed intelligence is now being applied using broadband-power-line (BPL) deployments in digitized energy grids. The upcoming generation of G.hn BPL semiconductors have enough processing power to provide distributed optimization of DER on the low voltage part of the electric grid. This form of distributed intelligence is vital to harmonizing energy fluctuations from renewables being integrated into the grid. Current case studies and applications by leading Green Energy Majors (European utilities at the forefront of distributed energy management) are features of this discussion
