Entergy Lake Charles 230/500kV Transmission Project

This project included a new turbine platform for Blattner to construct – 63 of the Nordex N149 4.8 MW turbines with a 108-meter hub height. With this larger turbine platform came a challenging foundation design. This construction consisted of a 62’ diameter radial rebar structure with 200 bolts at 14’ 3/8” in height yielding 603 cubic yards of concrete for the foundation base. Blattner’s scope of work also included 31 miles of subgrade, 79.5 miles of underground collection line and construction of the substation and O&M building.
