We provided comprehensive engineer-procure-construct (EPC) services for DTE Energy's Van Dyke Substation upgrade to meet the needs of customer Fiat Chrysler America (FCA). The project included replacement of all protective relaying, secondary structures and auxiliary equipment with two transformers feeding the FCA Sterling Heights Assembly Plant.
FCA is replacing both busses of 13.8-kV metal-clad switchgear feeding its plant and upsizing the incoming feeds from DTE’s substation. Each bus will be de-energized independently, leaving a tight window for upgrades to DTE’s equipment. The scope of work associated included:
Replacement of three full-sized relay panels and over 75 percent of existing yard cable
Replacement of two 13.8-kV bus structures and associated foundations, steel, fused disconnects, PTs, SSTs, animal guards and bus work
Upgrades to oil containment, ground grid and lighting.
We supported DTE, enabling successful completion of work for the north transformer to meet the aggressive outage window to energize FCA’s newly installed switchgear bus. The work for the second transformer window followed.
