In Mississippi, the December Public Service Commission meeting wasn’t simply a regulatory footnote; this meeting told the story of everyday life - bills, neighborhoods, and the choices that keep the lights on. The PSC’s decisions reach into your kitchen and your wallet, shaping reliability, fairness, and the cost of keeping the power on in communities across the state.
Spire Mississippi in the spotlight
Spire Mississippi was the featured player on the Energy Agenda this meeting, whether they wanted to be or not, starting with their Notice of Intent to Establish a Supplemental Growth Rider. The rider was designed to spur industrial development by allowing up to $5 million in investor-funded gas service expansions over a three-year period without project-specific commission approval. The rider’s promise was straightforward in theory: encourage growth and attract or support large projects that might not otherwise be feasible for a gas utility to fund on its own.
But Spire’s track record with the rider has been uneven. The company had not identified qualifying projects since the rider’s 2015 inception and, more recently, did not request an extension in October 2024. The discussion underscored a familiar regulatory tension: how to incentivize economic development without committing ratepayers to uncovered risk. Spire argued there is real potential—perhaps as many as 1,200 new customers—but uptake has been modest, with only 26 customers connected to date. Marketing and targeting strategies were cited as factors, along with competing capital priorities and broader market dynamics.
The chair framed accountability as an essential hedge against public money being deployed without adequate oversight, signaling a willingness to grant the rider again only if the process remains transparent and well-coordinated with staff and economic development partners.
Another docket item that captured attention involved Spire Mississippi again, this time in relation to its Rate Stabilization Adjustment Rider (RSA). The 2015-UN-109 filing reflected the utility’s annual update to the RSA, an important mechanism that modulates revenue requirements based on the company’s actual costs and investment activities. The initial filing anticipated an approximate $804,000 rate increase, with a residential bill impact projected at about $1.52 per month, anchored by assumptions such as a 10.73% return on equity and a rate base in the low tens of millions.
Regulators and staff scrutinized the filing, proposing adjustments to the rate base, revenues, and expenses. Those adjustments nudged the net income figure, and a joint stipulation between staff and Spire further refined the outcome. The net effect was a noticeably smaller increase: about $589,000, a 26.7% reduction from the original request. The revised trajectory called for recovery of the increase over January through October 2026, translating to roughly a $1.36 monthly uptick for the typical residential customer.
Belmont seeks rate increase to bring equity to customer base
Little Belmont, Miss. (population 2,021), contributed another dimension to the day’s discussions with a petition tied to its water rates in Docket 2025-UN-111. The town sought a significant rate increase to remedy a long-standing equity issue: inside-city ratepayers had subsidized customers beyond the town’s limits for years. The proposed change would align the cost of water service for outside-city customers with those inside the city, addressing a structural subsidy that regulators recognize as unsustainable in the long run. The math was clear: customers outside the city limits would see an approximate $12.72 monthly increase, derived from a typical usage pattern of about 3,800 gallons per month, with tiered pricing for the first 3,000 gallons and incremental increases beyond that.
Belmont’s data pointed to a total customer base of 1,157, of whom 41 lived beyond the one-mile service boundary. The filing noted that the municipality had extended service to those outside the city limits without a formal tariff on file, a gap the Commission sought to close by formalizing a tariff and ensuring proper governance. Staff argued that the proposed adjustment would be fair, just, and reasonable, aligning pricing with actual service costs and governance standards. The result would be a more equitable rate structure, albeit at the cost of higher bills for a subset of customers who have shouldered cross-subsidies for years.
All customers were notified, and there were no intervenors.
Shubuta Creek Solar project advances to formal hearing
And finally, the Energy Agenda also featured a procedural step regarding Shubuta Creek Solar, LLC, with an order of referral for hearing on Grenergy’s proposed facility in Jasper County (Docket 2025-UA-14). The motion to refer advanced to a formal hearing before Commissioner Carr, signaling progress in the regulatory review of a solar project that promises to diversify Mississippi’s energy mix and bring potential local development to Jasper County.
Final thoughts
It’s worth noting that the 41 residents of Belmont will see a spike in their water bill, and while they were notified of this pending action, they did not intervene. Intervening at the Public Service Commission often looks like speaking up on your own behalf, but the unfortunate reality is that too many residents around the Southeast are left in the dark as to the role the PSC plays in their lives - and in their pocketbooks. These blogs on the monthly, sometimes mundane business of commissions around the Southeast, are here to challenge that narrative and to help educate the public about their local commission.
As Mississippi’s energy landscape evolves, decisions made in rooms like the PSC hearing room have real-world consequences—on reliability, affordability, and the opportunities available to employers and communities across the state. For ratepayers and stakeholders, staying informed about these developments is not just a matter of civic duty but a practical path to understanding how public policy translates into everyday prices and service quality.
