HOW are we performing?




Cleaner, more renewable and diverse power-generation sources

Helping improve regional air quality by reducing our CO2 levels by 22%, NOx levels by 48% and SO2 levels by 65% from 2005-2017.

Reducing mercury emissions by 89% since 2005 by installing and optimizing mercury control technology at our Labadie, Meramec, Rush Island and Sioux energy centers as part of efforts to make the air cleaner.

Operating enhanced particulate control technology at our Labadie, Meramec, Rush Island and Sioux energy centers and maintaining ambient air monitors to ensure emissions are significantly below current state and federal air quality requirements.

Energizing the Spoon River Transmission Project, supporting Illinois' Renewable Energy Portfolio Standard.

Building one of the most technologically advanced utility-scale microgrids in North America. Located in Champaign, Illinois, the microgrid can produce energy from wind, solar and natural gas, and it also includes batteries capable of storing up to 250 kilowatts of electricity.

Working to responsibly transition Ameren Missouri to a cleaner, more renewable and diverse generation portfolio.

Investing approximately $2.6 billion in Federal Energy Regulatory Commission-regulated transmission infrastructure projects from 2017-2022 to help bring renewable power to the Midwest and maintain and improve reliability.

Investing in updates to ensure the integrity and efficiency of energy generation facilities, including a $52 million construction project at Bagnell Dam.

Implementing two pilot solar programs to increase renewable generation to benefit all customers.

Introducing the Charge Ahead program to encourage electric vehicle and equipment use among Missouri residents and businesses. The program offers customers fast-charging electric vehicle stations, improved air quality and new choices.

Implementing the Renewable Choice Program, an innovative way to help large businesses and cities across Missouri reach their renewable energy goals.

Responsible energy policy

Advocating for responsible energy policies and working with federal and state regulatory agencies to develop energy policies that reduce emissions, and protect the reliability and affordability of electricity for all of our customers.

Implementing the Missouri Energy Efficiency Investment Act 2016 plan. It features a budget of $158 million, a portfolio of customer energy efficiency programs, energy savings of 571 gigawatts and demand savings of 167 megawatts. The total benefits as a result of these energy efficiency programs are expected to reach nearly $425 million over the next 20 years.

For the four-year period starting January 1, 2018, the Ameren Illinois energy efficiency plan will save an average of 342 million kWhs annually of electricity at an average capital cost of $99 million a year resulting in over 1.36 billion kWhs saved. Additionally, the plan will save an average of 3.36 million therms annually of natural gas usage at an average operations and maintenance cost of $16 million per year resulting in approximately 13.4 million therms of energy savings.

Receiving financial and regulatory certainty through 2022 in the state of Illinois following the enactment of the Future Energy Jobs Act. The law also bolsters the state’s energy efficiency programs and investments in renewable energy.

Developing public policies that recognize the energy grid as the key to a reliable, sustainable, reasonably-priced and clean energy system. State and federal agencies can modernize economic regulations to encourage utilities to build and operate a more modern and smarter energy grid.

Preparing the next phase of energy efficiency to enable significant energy savings for our customers.

Reduced environmental impacts

Utilizing 56% of Ameren Missouri's energy center's coal combustion residuals in concrete markets, cement manufacturing and other beneficial use applications avoiding the disposal of these materials.

Recycling more than 146 million pounds of material in 2017, including copper, steel, aluminum, plastic and wood. Ameren voluntarily participates in the EPA’s WasteWise program.

Holding events such as the annual Adopt-the-Shoreline Cleanup at Lake of the Ozarks. In the 26 years since the program began, thousands of volunteers have worked to clean the shore and remove debris. In 2017, volunteers removed 53 tons of trash.

Earning LEED Gold status for The Hub, a converted empty building where the company’s Innovation Action Teams collaborate to share ideas, test theories and meet with other innovative thinkers in the energy technology space.

Enacting a detailed, aggressive plan to close all of Ameren Missouri's legacy ash ponds by 2023.

Seeking out and deploying innovative remediation technologies at 15 former manufactured gas plant sites to increase efficiencies and further reduce potential impacts to surrounding communities.

Transferring a 144-mile stretch of the former Rock Island rail line to the state of Missouri as part of the Rails to Trails Program. In two years, Ameren has salvaged nearly 72 million pounds of material.

Fostering environmental stewardship innovations in our supply chain.

Water conservation and quality

Implementing comprehensive, progressive plans of action in response to the EPA’s coal combustion residuals (CCR) rules, which designate that CCRs be managed as a non-hazardous waste. The rules apply to our Labadie, Rush Island, Sioux and Meramec energy centers.

Carrying out our plan of action in response to the EPA’s revised effluent guidelines for the steam electric power sector. As a good steward of the environment, Ameren is committed to protecting all natural resources, including water.

Implementing water conservation efforts at Ameren facilities in Illinois and Missouri, including our St. Louis headquarters.

Completing conversion of Ameren Missouri's Labadie, Rush Island and Sioux energy centers to dry ash handling, saving billions of gallons of water annually.

Participating in the Interagency Task Force to update the Missouri State Water Plan, as well as the Missouri River Recovery Implementation Committee, to assess and determine actions to enhance water resource management.

Continuing to investigate opportunities for water conservation and evaluate water availability and resource adequacy.

Our assessment covers the past several years and is current through March 1, 2018.
