The Monte Alto I project is a proposed 141.5 MW wind generation project located in Willacy County, Texas. Developed by Terra-Gen, it is interconnected within the ERCOT region under queue ID ERCOT-19INR0022. The project entered the interconnection queue on November 4, 2016, and has a proposed commercial operation date of June 1, 2028. An Interconnection Agreement (IA) was executed on February 13, 2020. The point of interconnection is at the tap 345kV 8318 Rio Hondo - 8383 N Edinburg.
The Monte Alto I project has been the subject of recent news coverage, with 35 articles mentioning the project. These articles primarily focus on deals within the energy industry.
