Canada’s net-zero grid mandate driving utility automation

Ottawa’s January 2025 Clean Electricity Strategy calls for 140-190 GW of new clean generation by 2050, effectively doubling current capacity. Utilities are digitising substations, deploying synchrophasors, and integrating distributed energy resources. Hydro Ottawa’s 2021-2025 roadmap accelerates digital platforms to orchestrate virtual power plants and demand response. These initiatives lift control-system spending in generation, transmission, and distribution assets.

Legacy brown-field systems with proprietary protocol lock-in

Plants built in the 1990s still rely on vendor-specific buses that complicate data acquisition and cloud connectivity. Phoenix Contact advises staged I/O migration to minimise shutdowns, yet integration crews must map thousands of legacy registers to modern object models—an effort that prolongs project timelines and inflates labor costs. Wood PLC notes that process-site lifecycles of 30 years make wholesale replacement impractical, obliging owners to fund dual-stack architectures for years.^{[2]Phoenix Contact, “Migration from Old Plants to New,” phoenixcontact.com}

Capital-intensive retrofit costs for OSHA functional-safety

Upgrading to SIL-rated logic solvers and adding redundant sensors represent multi-million-dollar outlays that smaller manufacturers often defer. NEMA’s maintenance guidelines emphasise scheduled verification but warn that deferred retrofits heighten unplanned downtime risk. Public transport operators echo similar challenges: APTA’s OT maturity framework shows many agencies remain at Level 1 due to budget constraints, leaving gaps in zoning and incident response. Limited capital envelopes slow the refresh cycle in the North American industrial control systems market.

Segment Analysis

By Component: Hardware retains dominance while services gain momentum

Hardware contributed 57.2% of 2024 revenue, led by sustained orders for PLC racks, DCS nodes, and motor drives. ABB’s Process Automation unit posted USD 6.8 billion of 2024 sales, showing continued appetite for capital equipment. Integration of edge analytics into controllers, such as Honeywell’s ControlEdge PLC with embedded OPC UA and MQTT, is boosting sell-through of premium SKUs.

Services, though smaller, are scaling rapidly at 8.9% CAGR as owners outsource lifecycle support. Rockwell Automation’s Lifecycle Services backlog reached USD 1.70 billion in September 2024, reflecting demand for outcome-based contracts that tie fees to availability gains. Skills shortages—3.5 million cybersecurity roles lacking by 2025—push maintenance and remote-monitoring agreements higher, elevating recurring revenue in the North American industrial control systems industry.^{[3]ABB Ltd., “ABB 2024 Annual Financial Report,” innovationpost.it}
