Do you think Missouri utilities should be allowed to raise natural gas rates?

Spire has filed a request with the Missouri Public Service Commission for a net increase of approximately $208.56 million in annual base-rate revenue. The company, which serves more than 1.2 million Missouri customers, says the average residential bill in western Missouri would rise by about $10 a month, or 11%, if approved as filed.

Why it matters

The request would affect households across Missouri who rely on Spire for natural gas service. Spire says the added revenue would support continued investment in its natural gas system, including modernization and upgrades intended to improve safety and reliability.

The filing seeks roughly $208.56 million in added annual base-rate revenue, which Spire projects would lift the average western Missouri residential bill by about 11%, or $10 a month. The Public Service Commission's final ruling on the amount remains pending within its 11-month review window.

The players

Spire Inc.

Spire is a publicly traded natural gas utility holding company that operates in Missouri, Alabama and Mississippi and serves more than 1.2 million Missouri customers.

Missouri Public Service Commission

The Missouri Public Service Commission is the state agency based in Jefferson City that regulates investor-owned utilities and reviews their proposed rate changes.

Consumers Council of Missouri

The Consumers Council of Missouri is an advocacy group that represents utility customers' interests and is monitoring the case.

The details

Spire filed the request on November 2, 2026, under case reference GR-2027-0075. Commission staff, including engineers, auditors and economists, will examine the company's information, and Spire bears the burden of proving the increase is justified.

November 2, 2026: Spire files its rate increase request with the Missouri Public Service Commission.
November 23, 2026: Deadline to apply to formally intervene in the case.
Within 11 months of filing: The Commission must decide on the request.

Market Landscape

Spire's filing initiates a standard general rate case before the Missouri Public Service Commission, the same state process that governs every investor-owned utility's request for higher base rates. The company must justify the increase, while commission staff examines its operating and investment costs before any decision is reached.

If approved as filed, Spire customers in western Missouri would see average residential bills rise by about $10 a month, or 11%. Residents can follow the case through the Consumers Council of Missouri, which is monitoring the proceeding.

The takeaway

Households in Missouri that depend on Spire should watch the case closely, since the final approved increase may differ from the amount requested. The November 23, 2026 intervention deadline is the window for stakeholders to take a formal role in the review.

What happens next

The Public Service Commission has 11 months from the November 2, 2026 filing date to decide the request, and the November 23, 2026 deadline to formally intervene falls within the review period.
