Ameren Missouri Announces Plans to Add 700 MW of Wind Generation by 2020

LCG, September 27, 2017--Ameren Missouri, a subsidiary of Ameren Corporation, announced Monday plans to add a minimum of 700 MW of wind generation by 2020, which represents an investment of approximately $1 billion. The new wind farms are expected to be located in Missouri and neighboring states. The company stated it also plans to add 100 MW of solar generation over the next 10 years, with 50 MW expected to commence operations by 2025.

The president of Ameren Missouri stated, "This is Ameren Missouri's largest-ever commitment to clean, renewable energy. We are committed to bringing our customers innovative solutions that are both cost-effective and environmentally responsible while maintaining the reliability our customers expect."

The addition of 100 MW of solar generation is planned in three stages: 25 MW by 2022, 25 MW more by 2025, and 50 MW more by 2027. Ameren Missouri is planning to build a solar generation facility at St. Louis Lambert International Airport that is expected to be complete in 2018. A second, separate project creates partnerships with business customers to locate an Ameren Missouri-owned solar generation facility on their property.

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 of 15% of annual retail sales by 2021.

Ameren Missouri also announced that will establish a goal of reducing its carbon emissions 80 percent by 2050 from the 2005 level. To achieve the goal, Ameren Missouri is targeting a 35 percent carbon emissions reduction by 2030 and a 50 percent reduction by 2040 from the 2005 level. Since 2005, Ameren Missouri has reduced carbon emissions by 26 percent in 2016. The company plans to retire over half of Ameren Missouri's roughly 5,100 MW of coal-fired generating capacity, including 594 MW of coal-fired capacity, at Meramec Energy Center in south St. Louis County by the end of 2022.

"We are the first investor-owned utility in the state, and among the first in the country, to announce a carbon emissions goal of this magnitude," said the president of Ameren Missouri.

The plans for new wind and solar resources, along with the reduced carbon emissions, were included in Ameren Missouri's Integrated Resource Plan (IRP) that was filed on Monday with the Missouri Public Service Commission. The IRP is a 20-year outlook that is filed every three years and examines electric customers' projected long-term energy needs and describes Ameren Missouri's preferred approach to meeting those needs.
