I NDUSTRY D RIVERS AND C HALLENGES Major grid transformation with the increased penetration of distributed and renewable energy resources, advanced metering, distributed control and automation, multiservice networks, among others. Increase of distributed generation is tending towards a lack of visibility and control at distribution level. Communication flow models have largely followed a one-way power delivery flow from generation to consumer. Most communication networks consist of multiple point-to-point circuits connecting substations to control centers for SCADA and EMS applications, and point-to-point circuits between substations for protection applications.

T HE FUTURE GRIDE W IDE A REA N ETWORK Electrical grids are shifting to an any-to-any power delivery model.
