Lacy Creek Wind Substation

The Lacy Creek Wind Project was a renewable project I was a design engineer on. It connected 108 GE turbines in the ERCOT region, and totaled approximately 300 MW of generation. My role in the project was related to the electrical and physical design of the 34.5 – 345 kV Generator Step-Up Substation.
