Ameren Missouri to Acquire 400-MW Wind Farm

LCG, May 23, 2018--Ameren Missouri, a subsidiary of Ameren Corporation, Monday announced that it has entered into an agreement to acquire, after construction, a 400-MW wind farm in northeast Missouri. The project will include 175 wind turbines to be installed by an affiliate of Terra-Gen, LLC. Construction is expected to commence in summer 2019.

Ameren Missouri's president stated, "We are excited to take this transformative step to bring more renewable generation to our customers. Adding more wind energy will help us achieve our goal to reduce carbon emissions 80 percent by 2050."

The wind farm acquisition advances the company towards targets incorporated in Ameren Missouri's Integrated Resource Plan (IRP) that was filed last September with the Missouri Public Service Commission (PSC). Targets included adding a minimum of 700 MW of wind generation by 2020. Ameren Missouri also announced in September that it will establish a goal of reducing its carbon emissions 80 percent by 2050 from the 2005 level.

The wind project will utilize the expanded transmission capacity made possible by Ameren Transmission Company of Illinois' Mark Twain Transmission Project, approved in January by the PSC. The Mark Twain Transmission Project has a targeted in-service date of December 2019.

The agreement to acquire the wind farm is subject to a number of conditions, including timely approval from the PSC and obtaining a timely and acceptable Midcontinent Independent System Operator (MISO) transmission interconnection agreement.

As part of its IRP, Ameren Missouri also plans to add 100 MW of solar-generated energy over the next 10 years, with 50 MW targeted to come online by 2025.

The State of Missouri has a mandatory renewable energy standard (RES) that requires investor-owned utilities (IOUs) to use eligible renewable energy technologies to meet 15 percent of annual retail sales by 2021.
