WHAT are we doing to demonstrate that?

2017 Integrated Resource Plan

Balancing the needs of our customers, the environment and the economy is important to all of us at Ameren. From preventing and controlling pollution, reducing greenhouse gases, and creating renewable energy initiatives to developing innovative technologies that help us operate cleanly, we are focused on being good stewards of the environment.

Ameren Missouri is executing a forward-thinking plan to dramatically increase the amount of wind and solar generation to provide cost-effective and sustainable energy for its customers. Our Integrated Resource Plan includes the addition of at least 700 megawatts of wind generation by 2020, representing a potential investment of approximately $1 billion. We also plan to add 100 megawatts of solar generation over the next 10 years, with 50 megawatts expected to come online by 2025.

Ameren Missouri is the first investor-owned utility in the state, and among the first in the country, to announce a carbon emissions reduction goal of 80 percent by 2050 from the 2005 level. To meet this goal, we are targeting a 35 percent carbon emissions reduction by 2030 and a 50 percent reduction by 2040 from the 2005 level.

Wind Solar Carbon-Reduction

Accessing Renewable Energy

Investments being made in our large, regional transmission system will improve access to renewable energy sources in the Midwest. The Spoon River Transmission Project was recently completed and energized, supporting Illinois' Renewable Energy Portfolio Standard. In Missouri, the Mark Twain Transmission Project was approved. The 96-mile line will complete a critical link in the region's energy infrastructure.

Improving Air Quality

The Missouri Department of Natural Resources says air quality has improved significantly in Jefferson County, Missouri. In a unanimous ruling, the state agency ruled the area should be re-designated as compliant for sulfur dioxide emissions. Ameren Missouri's Rush Island Energy Center, along with the other energy centers, have achieved dramatic decreases in SO2 and NOx emissions. The extensive air monitoring network continues to indicate there are no air quality issues. Concentration levels are far below federal standards, which the EPA defines as fully protective of public health and a margin of safety for the most vulnerable in the population.

Reducing Emissions


*Emissions from Ameren energy centers for calendar year 2017 compared with 2005 – including 2005 emissions from our Meredosia and Hutsonville energy centers (closed in 2011), but excluding 2005 emissions from energy centers divested in 2013 and 2014.

Climate Risk Report

In keeping with our commitment to environmental stewardship, during the first quarter of 2019, we will publish a report dedicated to climate risk. The report will include analysis of the potential impacts of future policy and technology changes on our generation portfolio and will leverage the results of our participation in the Electric Power Research Institute’s study regarding utility industry scenario analyses with respect to climate change.

Responsible Land Owners

Ameren is committed to protecting the environment. We believe that a sound environmental policy benefits our customers, shareholders and employees by enhancing the communities we serve. This means undertaking a range of efforts which include:

Remediating manufactured gas plants (mgp)

We are evaluating and remediating former MGPs. Representatives of the Illinois Environmental Protection Agency (IEPA) and Missouri Department of Natural Resources (DNR) help us oversee technical aspects of the cleanup work in both states, and they are also involved in community outreach.

Responsible landfill storage

A state-of-the-art dry landfill is in use at Labadie Energy Center. With a sophisticated clay and liner system to protect groundwater, it is the most robust design of any landfill in the state. This type of storage is a best-practice solution for coal combustion residuals.

Managing coal ash

Ameren Missouri is closing all of its legacy ash ponds. The detailed, aggressive closure plan calls for an increase in recycling as well as long-term monitoring of the site. All of the impoundments will be closed by 2023, with a majority finished by 2021. The closure timeline is in advance of requirements laid out by rules from the Environmental Protection Agency (EPA) related to coal combustion residuals (CCRs) that took effect in October 2015. See more on CCR management.

Protecting Water

Ameren continues to be a good steward and conservator of natural resources, including water.

In the past year, Ameren Missouri announced plans to save 11 billion gallons of water annually by converting to dry ash handling systems. That same announcement included new studies of surface and drinking water surrounding all four of the company's coal-fired energy centers. The studies show there is no adverse impact on surface or drinking water.

In addition, Ameren Missouri is continuing to comply with policies established during the Obama Administration concerning groundwater monitoring and reporting. Those federal rules required multiple rounds of sampling, which were conducted in 2016 and 2017. Detailed results are posted on our website.
