Karankawa

Start Date: October 2018

Completion Date: November 2019

The Karankawa Wind Farm is located four miles east of Mathis, Texas in San Patricio/Bee County and was developed by Avangrid Renewable Energy. Karankawa was very challenging to construct due to such a flat terrain that didn’t allow water to drain away from the site, but Wanzek worked extensively with the engineers and designed a wind farm that will last for 25–30 years. This project consists of 124 GE Turbines (114 GE 2.5 and 10 GE 2.3) that span across 22,000 acres of pasture and farm land. Karankawa delivers 308 MW of electricity and was completed on time/to the satisfaction of Avangrid Renewable Energy and all participating landowners.

Project Scope:

  • Access road construction
