ITEM 8.01 Other Events.
On June 22, 2022, Union Electric Company, doing business as Ameren
Missouri ("Ameren Missouri"), filed an update (the "2022 Update") to its September 2020 non-binding integrated resource
plan with the Missouri Public Service Commission ("MoPSC"). The 2022 Update reflects certain changes to Ameren Missouri's preferred
plan for meeting customers' projected long-term energy needs in a responsible fashion that maintains system reliability and customer
affordability. The 2022 Update includes:
| · | Adding
a total of 2,800 megawatts ("MW") of renewable generation by 2030 and 4,700 MW
by 2040, representing investment opportunities of approximately $4.3 billion and $7.5 billion,
respectively; |
| · | Adding
a total of 400 MW of battery storage by 2035 and 800 MW by 2040, representing a total investment
opportunity of $650 million; |
| · | Accelerating
the retirement date of the approximately 1,200 MW Rush Island coal-fired energy center from
2039 to 2025; |
| · | Extending
the retirement date of the approximately 1,000 MW Sioux coal-fired energy center from 2028
to 2030; |
| · | Retiring
approximately 500 MW of generation from Ameren Missouri's natural gas-fired energy centers
in Illinois by 2029 and approximately 1,800 MW by 2040; |
| · | Adding
1,200 MW of combined cycle generation by 2031, representing an investment opportunity of
$1.7 billion; and |
| · | Adding
1,200 MW of unspecified clean, dispatchable resources by 2043. |
Ameren Missouri’s plan could be affected by, among other factors:
the ability to obtain certificates of convenience and necessity from the MoPSC and any other required approvals for the addition of renewable
or other resources, retirement of energy centers, and new or continued customer energy-efficiency programs; the ability to enter into
build-transfer agreements for renewable generation and acquire that generation at a reasonable cost; the ability of developers to meet
contractual commitments and timely complete projects, which is dependent upon the availability of necessary labor, materials, and equipment,
including those that are affected by the disruptions in the global supply chain caused by the COVID-19 pandemic or government actions,
among other things; changes in the scope and timing of projects; the availability of federal production and investment tax credits related
to renewable energy and Ameren Missouri’s ability to use such credits; the cost of wind, solar, and other renewable generation
and storage technologies; changes in environmental regulations, including those related to carbon dioxide and other greenhouse gas emissions;
energy prices and demand; and Ameren Missouri’s ability to obtain necessary rights-of-way, easements, and transmission interconnection
agreements at an acceptable cost and in a timely fashion.
In connection with the 2022 Update, Ameren Corporation ("Ameren")
also revised its goals for reduction of carbon emissions. Ameren is now targeting net-zero carbon emissions by 2045, as well as a 60%
reduction by 2030 and an 85% reduction by 2040, based on 2005 levels. Ameren’s goals include both Scope 1 and Scope 2 emissions
including other greenhouse gas emissions of methane, nitrous oxide and sulfur hexafluoride. Ameren's emissions targets encompass direct
emissions from operations, as well as electricity usage at Ameren buildings. Achieving these goals will be dependent on a variety of
factors, including cost-effective advancements in innovative clean energy technologies and constructive federal and state energy and
economic policies.
Ameren Missouri expects to file its next integrated resource plan
with the MoPSC in September 2023.
