Utilities already rely on mature communications across electricity, gas, and water networks, but automation, renewable integration, intelligent field devices, cybersecurity pressure, and real-time operational data are changing the requirements. Existing networks can still support many current use cases, yet future operations will need greater resilience, scalability, prioritization, and governance across increasingly digital and distributed environments. The challenge is no longer simply connecting assets — it is keeping communications secure, resilient, and scalable as utility operations become more mission-critical
Private 5G gives utilities a dedicated communications platform for critical operations — connecting automation, field mobility, cybersecurity, and future grid modernization through one scalable foundation
Private 5G helps utilities govern availability, security policies, traffic prioritization, and operational performance directly
High device density and scalable coverage support substations, field assets, distributed resources, and mobile teams
Private core networks, OT cybersecurity controls, and centralized policy management strengthen secure operational communications
A single infrastructure investment can support outage management, DER integration, automation, workforce mobility, and autonomous grid operations
NTTデータのサポート体制は?
NTT DATA helps utilities assess where private wireless can support grid automation, field operations, OT/IT convergence, and long-term modernization

We help architect dedicated spectrum, 5G standalone infrastructure, private core networks, edge platforms, cybersecurity controls, and network management capabilities

Private 5G becomes stronger when it enables multiple operational priorities, including FLISR, DERMS, Smart Grid communications, and substation automation

Native integration with edge computing supports distributed decision-making, low-latency operations, and future AI-driven utility processes

We don’t treat 5G as another network layer. We design it as an operational platform for resilience, governance, and scale
