Industrial plants—and particularly pulp and paper mills—are facing increasing complexity, whether maintaining existing operations or implementing new systems.

• Aging infrastructure and evolving safety requirements
• Rising energy costs and efficiency demands
• Multiple suppliers and fragmented responsibilities
• Increasing grid instability and power quality challenges

As a result, mill operators often face higher coordination effort, increased project risk, limited transparency, and reduced operational stability.

Implementing new systems or expanding existing production lines introduces further complexity:

• Integration of new electrical systems with existing infrastructure
• Coordination between multiple engineering disciplines and suppliers
• Ensuring reliable system performance under varying operating conditions
• Validation of system design through studies such as load flow, short-circuit, grounding, arc flash, and protection coordination analyses

Without proper system integration and validation, projects can experience delays, unexpected interactions between systems, and increased startup risks.

Electrical system issues are rarely isolated events. In pulp and paper mills, they can quickly translate into production and operational challenges:

• Production breaks caused by power disturbances or drive trips
• Nuisance tripping during start-up or load changes
• Premature failure of motors, transformers, and drives
• Process instability caused by grounding issues, harmonics, or voltage imbalance
• Difficult root-cause analysis across interconnected systems

Even minor electrical disturbances can affect production stability, equipment reliability, and overall plant performance.

• Electrical system design aligned with process requirements

• Load flow studies
• Short-circuit studies
• Arc flash analysis
• Grounding studies
• Protection coordination

• Transformers
• Motor control centers
• Drives
• Power distribution systems
   

• Coordinated execution with minimized interfaces

• Future-proof solutions for existing plants

Traditional electrification approaches often focus on individual electrical components. In pulp and paper mills, however, electrical performance is closely connected to process performance.

By considering process requirements, operating conditions, and system interactions together, ANDRITZ helps reduce risk and improve plant reliability.

Green Bay Packaging's PowerPack project is a major mill modernization initiative focused on strengthening infrastructure, improving efficiency, and preparing the facility for long-term growth. Within this highly complex environment, ANDRITZ contributes integrated process, automation, and system solutions while supporting coordination across multiple disciplines and project interfaces.

The customer highlighted ANDRITZ's collaborative approach and commitment to developing future-proof solutions, demonstrating the value of integrated engineering and execution in a large-scale modernization project.
