Introduction

In 2026, global industrial automation markets are experiencing a strong wave of retrofit and modernization projects, especially in facilities still operating legacy systems from GE (including GE Fanuc heritage platforms) and Invensys (now part of Schneider Electric’s industrial ecosystem).

Instead of replacing entire production systems, industries are increasingly upgrading existing PLC, SCADA, and DCS infrastructures through hybrid modernization strategies. This trend is driven by cost pressure, cybersecurity requirements, and the need for digital transformation without production downtime.

Rising Demand for Industrial Retrofit Projects

Across oil & gas, power generation, water treatment, and heavy manufacturing industries, many plants are still operating systems installed 10–25 years ago.

These legacy systems often include:

• Old GE Fanuc PLC architectures
• Invensys Foxboro DCS systems
• Early-generation SCADA control platforms
• Proprietary communication protocols

In 2026, replacing these systems entirely is often too expensive and risky. Instead, companies are adopting incremental retrofit strategies.

Key drivers include:

• Increasing downtime risk in aging control systems
• Lack of cybersecurity in legacy architectures
• Difficulty integrating with modern IIoT platforms
• Rising cost of unplanned shutdowns

GE Vernova’s Role in Industrial Modernization

GE’s industrial energy and automation division (GE Vernova ecosystem) is playing a major role in supporting modernization of critical infrastructure.

Rather than focusing only on new installations, GE’s approach includes:

• Digital upgrades for existing control systems
• Industrial analytics integration for legacy assets
• Grid and power plant automation modernization
• Hybrid control system architectures

This allows industrial operators to extend system life while improving digital capabilities.

Invensys Legacy Systems Still Widely Used

Although Invensys has been integrated into Schneider Electric’s industrial portfolio, many industrial plants worldwide still rely on legacy Invensys systems such as Foxboro DCS.

These systems remain common in:

• Petrochemical plants
• Refinery control systems
• Power generation facilities
• Water treatment infrastructure

In 2026, modernization efforts focus on:

• Migrating Foxboro systems to open automation platforms
• Adding edge gateways for real-time data access
• Integrating with modern SCADA dashboards
• Enhancing cybersecurity layers without full replacement

Hybrid Modernization Strategy Becomes Industry Standard

Instead of full system replacement, industrial operators now use a hybrid approach:

• Keep existing PLC/DCS hardware
• Add edge computing modules
• Integrate IIoT sensors and gateways
• Connect to cloud-based analytics systems

This strategy reduces cost while enabling gradual digital transformation.

Cybersecurity as a Key Upgrade Driver

One of the biggest motivations for retrofitting legacy automation systems is cybersecurity.

Modern upgrades include:

• Secure industrial communication layers
• Network segmentation for OT systems
• Real-time intrusion detection systems
• Compliance with IEC 62443 standards

Older systems were never designed for internet connectivity, making them highly vulnerable today.

Conclusion

In 2026, GE Vernova and legacy Invensys systems are at the center of a global industrial retrofit wave. Instead of full replacement, industries are prioritizing hybrid modernization strategies that extend system life while enabling digital transformation.

This trend is reshaping the global automation upgrade market and creating strong demand for PLC, DCS, and industrial integration solutions.
