Biomass Plant

The University of British Columbia operates a central heating plant that was a significant source of campus greenhouse gas emissions — a direct conflict with UBC's formal commitment to reducing its environmental footprint. Managing a biomass-fueled energy facility at institutional scale requires precise control over combustion, motor systems, and fuel handling, yet the plant lacked integrated visibility across these systems. Without unified control and real-time data, operators could not optimize performance or document emissions reductions in a way that satisfied sustainability reporting requirements. The status quo left measurable decarbonization potential unrealized.

Rockwell Automation implemented a fully integrated control and monitoring architecture across UBC's biomass heating plant. Two ControlLogix Programmable Automation Controllers (PACs) form the backbone of the Integrated Architecture system, providing coordinated control across all plant systems. Three CENTERLINE 2100 Motor Control Centers, equipped with integrated PowerFlex 40 and PowerFlex 700 AC drives, deliver precise motor control for fuel handling, combustion air, and auxiliary equipment. On the visualization layer, FactoryTalk View ME software provides machine-level operator displays while FactoryTalk View SE delivers plant-wide supervisory visibility. FactoryTalk Historian ME captures and logs operational data, automatically reporting facility performance metrics to a Nexterra server — enabling continuous emissions accounting and process optimization without manual data collection.

The integrated control system delivered a measurable and reportable environmental outcome:

• 6,000 tons of greenhouse gas emissions eliminated per year — directly supporting UBC's campus sustainability targets

Beyond the headline figure, the unified architecture gave plant operators real-time visibility into system performance that was previously unavailable. Automated data reporting to the Nexterra server removed manual logging burdens and created an auditable emissions record. The standardized Rockwell platform also positions the facility for future expansion or integration with broader campus energy management systems.

• Integrated control architecture pays dividends beyond automation — unified data flows make emissions reporting auditable and defensible without additional manual effort.
• Pairing variable-speed AC drives (PowerFlex series) with centralized PAC control is a proven approach for optimizing energy-intensive motor loads in industrial utility plants.
• Historian software that feeds directly to a process partner's server (Nexterra) eliminates reporting gaps and supports third-party verification of environmental claims.
• Biomass plants have complex interdependencies between combustion, fuel handling, and auxiliary systems — a single integrated platform reduces integration risk compared to point solutions.
• Sustainability commitments at institutional facilities can accelerate automation investment approvals; framing the business case around measurable emissions outcomes improves stakeholder buy-in.
