The two will integrate their solutions to provide utilities with a unified end-to-end networking service which meets optical, MPLS-TP, IP/MLPS or TDM communications requirements.
GE will scale its solutions with ECI's Apollo optical family or Neptune family with Elastic MPLS, which supports both MPLS-TP and IP/MPLS on the same network element.
ECI will also offer GE Renewable's JunglePAX MPLS-TP solution to its global customers in need of industrial hardened, fanless, resiliency and optimised packet transport modes for critical infrastructure.
The deal is part of efforts by GE Renewable Energy and ECI to expand their industry footprint.
The partnership follows utilities in previous years managing their IT and OT networks in siloes.
However, digitisation of grid networks now require energy providers to use heterogeneous networks to streamline siloed IT and OT operations to improve grid efficiency, reduce downtime, lower operational costs, minimise asset risks, and increase customer satisfaction.
Chris Trabold, general manager of industrial communications at GE Renewable Energy, said: "As utilities face new challenges and embrace new technologies, we understand just how critical it is to minimise disruption while modernising."
