The Federal Energy Regulatory Commission approved Ameren Missouri's request to acquire the 400-MW High Prairie Wind Farm in Adair and Schuyler counties, Mo., for an undisclosed sum.
An affiliate of New York-based Terra-Gen LLC will sell its stake in the proposed project, according to a Dec. 14 FERC filing.
Ameren expects the wind project to begin commercial operations by December 2020. The project will be interconnected to affiliate Ameren Transmission Co. of Illinois' 100-mile, 345-kV Mark Twain transmission line in the Midcontinent ISO market. It is part of the company's objective to invest in 700 MW of wind energy resources to comply with Missouri's renewable energy standard.
Ameren Missouri is known legally as Union Electric Co. and is a subsidiary of Ameren Corp. (FERC docket EC18-133)
