In the spring of 2022, Wilkins Lumber Company in Milford, NH communicated a concern about inordinate demand charges, along with a desire to advance their sustainability and decarbonization objectives.
Energy LB analyzed their sawmill network through data recording at distinct network locations during a week of production. High reactive power levels, significant voltage instability and current imbalance across phases were observed in the recorded data. These phenomena contribute to heat dissipation and loss, reduced torque available to motor loads, degradation of efficiency, performance and life of equipment.
The sawmill was not utilizing its power supply efficiently or effectively. A power quality solution was crafted and installed to improve the operational energy profile. Check out the full case study below!
