Title
A RESOLUTION AUTHORIZING THE CITY MANAGER TO ENTER INTO A PROFESSIONAL SERVICES CONTRACT WITH GPD GROUP FOR THE PURPOSE OF PERFORMING AN ARC FLASH STUDY.
Brief Description: The proposed Arc Flash Study will evaluate Hudson Public Power's substations and distribution system's arc flash rating, safety requirements and clearances based on configuration, load and equipment. Arc Flash studies are performed on a 5-year cycle to account for changes in the operations and equipment utilized in the electrical system.

Purpose & Explanation
An arc flash study in a substation is conducted to evaluate the potential energy released during an electrical fault, such as an arc flash event. Its primary purpose is to identify hazards, determine appropriate personal protective equipment (PPE), and establish safe working boundaries. By analyzing system parameters and fault conditions, the study helps ensure compliance with safety standards (like NFPA 70E) and protects personnel from serious injuries caused by high-temperature blasts and intense light during arc flash incidents.
Arc flash studies should be reviewed and updated at least every five years, or sooner if there are significant changes to the electrical system-such as equipment upgrades, load changes, or modifications to protective devices. Regular updates ensure that safety protocols remain accurate and effective in preventing electrical accidents.
The GPD Group, who is familiar with the City's municipal substations and distribution system was selected to perform this study. The proposed scope and fee for this evaluation is $34,500. Staff is requesting a 10% contingency for the study, bringing the total proposed fee to $37,950 ($34,500 + $3,450 = $37,950).
