My Coolest Project:
I led the design and construction team for powering a new Digital Reality Data Center with 80MW capacity. We installed six new feeders with more than 20 miles of 34kV cables coming from four different substations across west Chicago. What was interesting was working with the customer to make sure we met the electrical needs and due dates, as well as ramp-up schedule, while still working off-site on capacity expansion.
