The work integrated new controls, emissions systems, and utility coordination, all while maintaining continuous facility operations through careful planning and temporary power solutions.

HH Angus was engaged to retrofit an existing 1800 kW diesel generator and add a new 1250 kW unit for parallel grid operation with remote dispatch and Urea emissions after-treatment. Grid controls included anti-islanding protection, SCADA integration, and transfer trip functionality. The new generator required replacement of the local 1500 kVA transformer. Maintaining uninterrupted facility operations was a key challenge, as the existing generator supported life-safety systems.

HH Angus coordinated carefully, deploying rental generators and using fast change-out methods such as single-bolt bus duct to minimize shutdowns.

Although budget constraints were a factor, a broader financial review justified the higher capital investment based on stronger long-term payback. Collaboration with the local utility further streamlined the schedule: protection systems were installed once, in coordination with the utility’s concurrent substation upgrade, eliminating redundant work.
