This case study looks at the successful delivery of a critical electrical upgrade at a high-capacity industrial incineration plant, where reliability, safety and operational continuity are essential.
The goal was to modernise the plant’s ageing electrical infrastructure by replacing the existing Motor Control Centre (MCC), renewing plant-wide wiring, and improving the system’s long-term reliability, safety and maintainability.
The project covered the full lifecycle of engineering works, from detailed design and manufacture of a new MCC through to installation, comprehensive rewiring and final commissioning. The result was a modernised electrical infrastructure that strengthens the facility’s performance today while positioning it for the demands of tomorrow.
The Challenge: Aging Infrastructure in a Demanding Environment
Incineration plants operate under extreme and continuous conditions—high temperatures, heavy loads, and strict regulatory oversight. The existing MCC and associated wiring systems had served the plant for many years, but like all legacy infrastructure, they were increasingly presenting operational and strategic risks:
- Rising Failure Rates: Aging contactors, breakers, and control gear were approaching end-of-life, increasing the likelihood of unplanned shutdowns.
- Obsolescence Issues: Critical components were no longer supported by manufacturers, making replacements costly, delayed, or unavailable.
- Maintenance Burden: Engineering teams faced growing time and cost pressures to keep the system operational.
- Safety & Compliance Gaps: Older installations lacked the protective features and segregation standards expected under current regulations.
- Limited Visibility & Control: Legacy systems offered minimal diagnostic capability, slowing fault-finding and recovery.
In a process where downtime directly impacts throughput, emissions compliance, and revenue, these risks could no longer be tolerated.
The Solution: A Fully Integrated Electrical Upgrade
To address these challenges, a comprehensive upgrade strategy was implemented—focusing not just on replacing equipment, but on transforming the plant’s electrical backbone.
- Bespoke MCC Design & Manufacture
The new MCC was purpose-built to meet the specific operational profile of the facility. Key design features included:
- Modular, extensible architecture to allow future expansion
- High-specification switchgear and motor starters for critical loads
- Segregated compartments to enhance safety and fault containment
- Integration-ready controls for SCADA and plant monitoring systems
This ensured the MCC was not only a replacement—but a significant technological step forward.
- Strategic Installation with Minimal Disruption
Working within a live industrial environment required meticulous planning. Our teams coordinated closely with plant operators to:
- Implement phased shutdowns and changeovers
- Maintain critical processes during transition periods
- Execute works safely within confined and high-risk areas
The installation was delivered on schedule, with minimal impact on plant availability.
- Full Plant Rewiring
A cornerstone of the project was the complete replacement of all plant wiring—often overlooked, but vital to system integrity.
This included:
- Removal of aging, degraded, and poorly documented cabling
- Installation of new, clearly routed and labelled cable systems
- Upgraded containment and segregation to reduce interference and improve safety
- Enhanced cable management for easier maintenance and troubleshooting
The result is a cleaner, more robust, and far more maintainable electrical distribution network.
- Commissioning & Validation
Following installation, a rigorous commissioning process ensured every aspect of the system met performance and safety expectations:
- Functional testing of all MCC sections and motor circuits
- Verification of protection settings and fault response
- Integration testing with existing plant systems
- Documentation and handover to site engineering teams
This phase ensured a smooth transition from old to new, with confidence in long-term performance.
The Benefits: Immediate Impact & Long-Term Value
The completion of this project delivers substantial operational, financial, and safety benefits:
Improved Reliability & Uptime
Modern equipment, combined with a fully renewed wiring system, drastically reduces the risk of faults and unexpected outages—ensuring consistent plant operation.
Enhanced Safety Standards
Upgraded protection systems, improved segregation, and compliance with current electrical standards significantly reduce risk to personnel and equipment.
Operational Efficiency & Control
Advanced MCC design enables better monitoring, faster diagnostics, and more precise control of plant processes—translating into improved productivity.
Reduced Maintenance Costs
With new, standardised components and clear wiring infrastructure, maintenance becomes faster, simpler, and less resource-intensive.
Energy Efficiency & Sustainability
More efficient motor control and reduced system losses contribute to lower energy consumption—supporting both cost reduction and environmental goals.
Future-Ready Infrastructure
The modular MCC design and modern wiring framework provide a platform for digitalisation, automation upgrades, and capacity expansion.
A Critical Upgrade for Critical Infrastructure
This project underscores the importance of proactive investment in electrical systems within heavy industrial environments. By replacing an aging MCC and completely renewing plant wiring, the facility has secured a resilient, high-performance foundation for continued operation.
From initial concept through to commissioning, this upgrade demonstrates how thoughtful engineering and careful execution can transform risk into opportunity—delivering not just compliance, but competitive advantage.
