Summary

• Ameren Missouri has filed a request with the Missouri Public Service Commission (MoPSC) to increase its annual revenues for electric service by $446 million.
• The rate increase request is based on a 10.25% return on common equity and a capital structure of 52% common equity.

• Ameren Missouri is also seeking to continue using the fuel adjustment clause and trackers for various items such as pension benefits and tax credits.
• The rate increase is intended to cover increased infrastructure investments, including those under the Smart Energy Plan, and investments in generation resources like solar projects and the Callaway nuclear plant.

Industry Context

This rate increase request is part of a broader trend in the utility industry where companies are seeking to recover costs associated with infrastructure upgrades and investments in renewable energy. Many utilities are facing similar challenges in balancing the need for reliable energy with the transition to cleaner energy sources.

Comparison to Industry Standards

• A 10.25% return on equity is within the typical range for regulated utilities, but the specific approval will depend on the MoPSC's assessment of the company's costs and investments.
• The capital structure of 52% common equity is also fairly standard for utilities, reflecting a balance between debt and equity financing.
• Other utilities such as Duke Energy and Southern Company have also been investing heavily in renewable energy and grid modernization, and have sought rate increases to recover these costs.
• The 500 MW solar project is a significant investment, comparable to other large-scale renewable energy projects being undertaken by utilities across the US.

Stakeholder Impact

• Shareholders may benefit from the potential for increased revenue and return on investment.
• Customers may face higher electricity bills if the rate increase is approved.
• Employees may benefit from the company's continued investment in infrastructure and renewable energy.
• Suppliers and contractors may benefit from the company's ongoing projects.

Next Steps

• The MoPSC will review the rate increase request.
• A decision from the MoPSC is expected by May 2025.
• New rates could become effective by June 2025.
