This project was part of the NYSEG Breaker Replacement Program for Avangrid’s Five-Year Capital Investment Plan (2016–2020). The substation assets upgrades were required to maintain the reliability of the power system, as well as prevent outages and accidents. Typically, breakers are replaced when the equipment has reached the end of its useful life or has a fault.
K&A performed the engineering and design of two new 8.3 kV circuit breaker replacements, new voltage transformers and a new remote terminal unit (RTU). Design scope included:
Project deliverables included one-line, three-line, foundation design, structural steel, point-to-point wiring diagram, conduit layout, grounding layout, schematics and equipment specification.
The K&A team developed a schedule for detailed engineering design, including dates for all major milestones, as well as conducted all necessary fieldwork prior to and during design. K&A also managed and coordinated existing substation drawings using NYSEG’s document control system, UDI, while project deliverables were transmitted through the ProjectWise contractor portal.
Upon construction completion, K&A will provide for-record drawings based on markups and previous designs by the installation contractor.
