Industry Context

This rate case filing is a common practice for regulated utilities like Spire Missouri to recover costs associated with infrastructure investments and operational expenses. It reflects the ongoing need to maintain and upgrade natural gas distribution systems while ensuring a reasonable return on investment.

Comparison to Industry Standards

• Rate cases are a standard process for regulated utilities, and the 11-month review period is typical for such filings.
• The requested return on equity of 10.5% is within the range of what is often sought by utilities, but the final approved rate can vary based on regulatory decisions.
• The 32% increase in rate base since the last filing is significant and may be scrutinized by the MoPSC, as it is higher than some other utilities have experienced over similar periods.
• Companies like Atmos Energy and Laclede Gas (now part of Spire) have also filed rate cases in the past, and their outcomes can provide a benchmark for comparison.

Stakeholder Impact

• Shareholders may see a positive impact if the rate increase is approved, as it could improve the company's financial performance.
• Customers may face higher natural gas bills if the rate increase is approved.
