Mill-wide Energy Audit, Pope & Talbot, Harmac Division

Pope & Talbot Ltd., Harmac Division (now Harmac Pacific) retained Allnorth to update and validate its mill-wide thermal energy and power balance and conduct a mill-wide energy audit.  One of the key findings of the audit was that mill’s existing governor control strategy was unnecessarily restricting the turbine’s extraction flow.  Following programming modifications to the governor (at zero capital cost), the mill’s incremental power generation improved by approximately 0.7 MW in the summer and 2.1 MW in the winter. Annual savings in excess of 11 GWh per year were achieved as a result of these modifications.

Allnorth’s responsibilities for this project included:

  • Updating and validating mill-wide thermal energy and power balance
  • Conduct a mill-wide energy audit
  • Mechanical engineering
