Mississippi Developer Files PSC Declaratory Opinion to Carve Private On-Site Data-Center Power Out of "Public Utility" Definition — a Regulatory Workaround Other States Will Watch

Jackson-based Gabriel Prado's PraCon Global Investment Group, acting through affiliate Prado AI Industrial, has filed a Request for Declaratory Opinion with the Mississippi Public Service Commission asking the commission to confirm that private, on-site power generation used for internal consumption — including by tenants on the same site — does not constitute a “public utility" under Mississippi law. A declaratory opinion is a binding interpretive ruling a regulator issues at a party's request — it tells the party in advance how its proposed conduct would be treated under existing law, without requiring a contested case to force the question.
If the PSC grants the opinion, the ruling creates a regulatory carve-out. A data-center developer could build dedicated generation (gas turbines, batteries, whatever the load profile requires), lease space to data-center tenants on the same parcel, and sell power to those tenants — all without entering the state's public-utility regulatory structure. No utility-scale rate case. No integrated resource planning review. No commission oversight of the generation's interconnection terms or the pricing to tenants. The developer's stated target customers are AI semiconductor facilities and hyperscale data-center operators across Mississippi.
The incumbents the ruling would route around are named: Entergy Mississippi and Southern Company (Mississippi Power). Under the status quo, a 500-MW data-center load siting in either territory would normally mean a generation-and-transmission plan filed by the utility, reviewed by the PSC, and paid for via a combination of customer contracts and tariffs. Prado's declaratory-opinion pathway would allow the generation to be built outside that framework entirely.
The legal theory is sophisticated. Mississippi's public-utility definition turns on whether the entity serves “the public” — and Prado is arguing that a single integrated campus serving a defined set of tenants is categorically not public service. If the PSC agrees, the opinion becomes citable precedent the first time another state PSC receives a parallel filing.
This is a case worth tracking even if you don't live in Mississippi. The Ohio Supreme Court today ruled the opposite way on the underlying question — that supplying electricity to consumers triggers utility regulation regardless of the supplier's corporate structure. Mississippi will be the first state to test whether a declaratory-opinion path can establish the Prado framing before a contested case forces the question through a rate proceeding.
What You Can Do
If you live in Mississippi
The Mississippi Public Service Commission (psc.state.ms.us) accepts public comments on declaratory-opinion filings. Check the commission's docket system for the Prado AI Industrial filing and submit comments — particularly if you live in a county where Prado's affiliates are scouting sites. The Mississippi Public Utilities Staff, which represents consumers, is likely to take a position on the filing.
If you work on energy policy in any other state
Read the declaratory-opinion filing when it becomes public. The legal argument is portable. If Mississippi grants it, expect parallel filings in Louisiana, Tennessee, Alabama, and West Virginia within months — every state with a public-utility definition keyed to service to “the public” is a candidate jurisdiction. State consumer counsels should be preparing their response arguments now, before the filings arrive.
Compare to the Ohio ruling issued today
The Ohio Supreme Court's submetering decision (Columbus Dispatch, April 24) is the most complete recent articulation of the opposite legal theory — that functional provision of electric service to end users is what triggers utility regulation. The Ohio case involved residential tenants; the Prado case involves data-center tenants. The underlying statutory question is close enough that state regulators will be cross-citing the two rulings for the next five years.
Track the FERC angle
If on-site generation crosses interstate-commerce thresholds or interacts with the regional grid, the Federal Energy Regulatory Commission (FERC) has concurrent jurisdiction. FERC's recent delay of large-load interconnection rules raised federal-state jurisdictional questions around precisely this kind of facility. Watch for FERC and NARUC positions as the Mississippi filing develops.
Community Takeaway
The Prado filing is a test case for a regulatory pattern that data-center developers have been pursuing informally for two years: build your own generation, call it private use, and leave the utility — and the utility's rate base — out of the transaction.
If it works, the consequence is straightforward. Data-center operators with the capital to self-generate can route entirely around state public-utility commissions. The protections PSCs nominally provide — integrated resource planning, cost-of-service review, interconnection standards, rate-design review — apply only to customers who remain on the utility system. The customers most able to exit the system are the customers whose load profile would otherwise subsidize (or, depending on your model, destabilize) the system.
If it doesn't work — if the Mississippi PSC rules that serving tenants on a commercial campus is categorically “public service” — then the state's public-utility definition holds, and the Ohio court's approach (functional service triggers regulation) becomes the dominant interpretive path. Every state PSC that gets a parallel filing will then have a recent, adverse ruling to cite.
Watch closely. The declaratory-opinion docket in Jackson is, in practice, the most consequential single regulatory venue in the country for the next ninety days — not because Mississippi has a lot of data centers, but because the legal theory being tested here, if validated, becomes the template used to deregulate hyperscale load nationwide. State-specific — public-utility definitions, declaratory-opinion procedures, and commission authority vary meaningfully by state. Verify how the parallel regulatory path would operate in your own state before assuming this case's outcome controls.
