Hitachi Energy and Rockwell Automation Unite to Accelerate Electrification

Hitachi Energy and Rockwell Automation have partnered to deploy an integrated grid-to-process architecture combining power infrastructure with production management systems across heavy industries. The collaboration targets energy-intensive operations, beginning with the mining and metals sector, where operational continuity depends on coordinated electrical distribution and process automation.

Operational Convergence and Engineering Drivers
Industrial facilities traditionally design power distribution networks and production lines in isolation. Rising power demand, decarbonization mandates, and capital expenditure limits require unified electrical and process planning. Decisions regarding grid connection, power quality, and load management directly influence plant throughput and equipment wear. Combining these domains enables engineering teams to coordinate cross-functional commissioning, reduce design redundancies, and lower deployment risks for high-load operations.

Technical System Architecture and Domain Division
The joint solution interfaces electrical protection, control systems, and energy management hardware with plant-level distributed control systems. Hitachi Energy delivers expertise in high-voltage grid connections, power quality stabilization, and electrical protection systems. Rockwell Automation provides industrial automation controllers, supervisory control interfaces, and digital process optimization software. At the system level, bidirectional data exchange between the power grid feed and production controllers allows dynamic load balancing during energy-intensive mechanical processing, preventing voltage fluctuations and equipment trips.

Target Applications in Mining and Metallurgy
Initial implementations address critical mineral extraction and metallurgical processing facilities. These operations rely on energy-dense, non-linear mechanical loads, including primary jaw crushers, semi-autogenous grinding mills, slurry pump skids, and long-distance bulk material conveyors. Disruptions or power anomalies in these subsystems halt continuous production streams, leading to process blockages and costly maintenance cycles. The integrated architecture stabilizes voltage profiles during dynamic motor starts and aligns energy dispatch with variable production throughput.

Performance Impact and Scalable Infrastructure
Integrating power telemetry with process control gives plant operators real-time visibility into specific energy consumption per ton of processed material. This combined architecture establishes a modular baseline that accommodates facility expansions, on-site renewable energy integration, and increasing machine electrification without requiring full electrical redesigns. By linking power quality metrics to asset performance tracking, operators reduce unplanned downtime and optimize energy efficiency across continuous industrial workflows.
