Data Center Developer Sues PSO: A Look at Rising Interconnection Risks

Executive Summary

A data center developer has filed suit against Public Service Company of Oklahoma (PSO), alleging unfair treatment in the interconnection process — a rare public window into the friction points that routinely derail large-scale data center projects before they break ground. The case signals that interconnection access is no longer a background administrative task; it is a front-line legal and commercial battleground. Developers who treat utility relationships as a formality are now watching a peer take that dispute to court. Utilities face new accountability pressure. The InfraSale takeaway: interconnection risk must be priced into every site acquisition and development timeline, not managed reactively after a problem surfaces.

What Happened

A data center developer has initiated a lawsuit against PSO — the Oklahoma-based electric utility and subsidiary of American Electric Power (AEP) — over allegations of unfair treatment in the interconnection process. The complaint offers an unusually direct look at how interconnection disputes between developers and utilities can escalate from regulatory friction into litigation.

Specific allegations, project size, MW capacity requested, and site location were not fully detailed in the available source material. What is clear is that the developer believes PSO acted in a manner that disadvantaged their project relative to others competing for the same grid access — a claim with meaningful implications for how utilities manage their interconnection queues and what obligations they owe to applicants.

The phrase "there's a lot of money" referenced in reporting underscores the financial stakes. Data center interconnection requests routinely involve 50 MW to 500 MW or more of load, with capital commitments in the hundreds of millions of dollars riding on grid access decisions made by a single utility.

Why This Matters

This lawsuit is not an isolated grievance. It is a symptom of a structural problem: interconnection queues across SPP, MISO, PJM, and ERCOT are oversubscribed, utilities face resource and staffing constraints, and the volume of data center load requests has surged dramatically alongside AI infrastructure buildout. When developers feel they are being treated inconsistently, courts become the next stop.

The legal outcome here could establish — or at least test — what procedural obligations utilities owe to large load customers in the interconnection queue. A ruling or settlement that favors the developer would create leverage for other applicants who feel their requests were deprioritized or handled opaquely.

Industry context: Utilities are not legally obligated under most state frameworks to process large load interconnection requests in the same standardized way that FERC Order 2023 governs generation interconnection. This regulatory asymmetry leaves data center developers with less procedural protection than solar or wind developers in queue — which makes disputes like this one more likely, not less.

For the broader market, the signal is clear: developer-utility relationships are under strain, and legal risk is a new line item in data center development pro formas.

Power & Interconnection Impact

PSO serves a service territory that spans much of eastern and central Oklahoma, operating within the Southwest Power Pool (SPP) footprint. Any dispute over how PSO manages large load interconnection requests implicates not just this single project but the queue dynamics for every other applicant seeking capacity in the same substations or transmission corridors.

If a court finds that PSO applied inconsistent standards in processing the developer's request, it could trigger a review of utility interconnection procedures for large loads across other AEP operating companies and potentially draw FERC scrutiny — particularly as FERC has signaled increased interest in transmission access and load growth accommodation.

Assumption: Developers active in SPP territory or other regions with high interconnection demand should treat this litigation as a preview of disputes that are likely to emerge in their own queue processes, particularly where substation capacity is constrained and multiple large load customers are competing for the same interconnection point.

The practical implication: data center developers cannot assume that a utility's verbal commitment or preliminary study results translate into a protected queue position. Contractual clarity and documented process records are now defensive necessities.

Land, Zoning & Permitting Impact

The direct land and zoning dimensions of this lawsuit are limited based on available source material. The core dispute appears to center on interconnection access, not land use approvals or local permitting.

That said, interconnection delays have downstream land consequences. When a developer cannot secure a grid interconnection agreement on schedule, site control costs accumulate — ground leases, option extensions, and carrying costs on entitled land can erode project economics significantly before a shovel touches the ground.

Industry context: In markets where data center demand is high, the lag between site entitlement and interconnection certainty is a known gap. Developers who lock up entitled land before confirming interconnection readiness are exposed to exactly the kind of extended holding-cost risk that this dispute illustrates. Zoning approvals from local governments may also face political pressure if a project stalls publicly — communities that approved a project expecting jobs and tax revenue become skeptical if development timelines slip without explanation.

Turn this intelligence into a deal

InfraSale connects landowners, developers, and tenants directly — skip the broker chain.

This lawsuit reframes interconnection access from a technical checkbox into a legal and financial risk category that investors and capital allocators need to underwrite explicitly.

Queue position is not a guarantee. A utility's acceptance of an interconnection application does not lock in access, timing, or cost. Litigation is now a demonstrated outcome when developers believe the process was unfair.
Oklahoma / SPP territory carries near-term uncertainty. Until this case resolves, developers and investors evaluating PSO-served sites should model extended interconnection timelines and potential cost increases into their underwriting.
Utility relationships require documentation. Projects that maintain formal written records of all utility communications, commitments, and study results have a defensible paper trail. Those that rely on informal coordination do not.
Legal risk is now a site selection variable. Developers may favor markets with utilities that have demonstrated transparent, consistent large-load interconnection processes — even if those markets carry higher land or construction costs.
Precedent potential is real. A plaintiff-favorable outcome could open the door to similar claims nationally, increasing litigation exposure for utilities and potentially accelerating federal or state regulatory reform around large load interconnection standards.

InfraSale Market Angle

For developers actively sourcing sites or evaluating interconnection opportunities, this case is a live risk signal — not a future hypothetical. The PSO lawsuit makes visible what many in the industry have experienced quietly: utilities exercise significant discretion in how they manage large load requests, and that discretion is not always applied consistently.

Developers using InfraSale to identify powered land and data center sites should prioritize locations where the utility's interconnection track record for large loads is documented and positive. Sites where substation capacity is confirmed, where the utility has executed large-load agreements with comparable customers, and where queue position is verifiable carry substantially lower execution risk than sites where interconnection status is "preliminary" or utility relationships are untested.

Landowners and site sellers with confirmed utility capacity — particularly sites with existing substation access, available feeder capacity, or legacy industrial load history — are holding assets that command premium attention in this environment. The PSO case makes that differentiation more valuable, not less.

Take Action

The PSO lawsuit is an early indicator of a legal and regulatory shift in how interconnection access disputes get resolved — and developers who are not tracking it are flying blind on a risk that is now documented in public court filings. If you are evaluating sites, sourcing power capacity, or positioning a project for capital, the time to stress-test your interconnection assumptions is before you are in a dispute, not after.

FAQ

What are the implications of the PSO lawsuit for data center developers?

The lawsuit signals that interconnection disputes can escalate beyond utility negotiations into formal litigation — a path that is expensive, time-consuming, and uncertain in outcome. Developers should treat this as a prompt to audit their own utility agreements, queue documentation, and site selection criteria for interconnection risk. Projects in SPP territory or with PSO specifically warrant immediate review.

How could this lawsuit affect future data center projects?

If the developer prevails, utilities may face greater pressure to apply consistent, documented standards when processing large load interconnection requests — which could slow queue processing in the short term while utilities update procedures. Assumption: a settlement or ruling could also accelerate regulatory discussions at the state utility commission level in Oklahoma and potentially draw FERC attention to large load interconnection standards more broadly.

What should investors watch for in this legal case?

Watch for three indicators: whether the case proceeds to discovery (which would surface internal utility communications about queue management), whether a state utility commission intervenes, and whether FERC takes any interest in the dispute as part of its broader transmission access agenda. Each of those developments would expand the market implications significantly beyond Oklahoma.

Does interconnection risk affect land values for data center sites?

Yes, directly. Sites with confirmed substation access, available capacity, and a utility track record for large load agreements trade at a meaningful premium over sites where interconnection status is speculative. This lawsuit makes that pricing differential more legible to buyers and sellers who may not have previously quantified interconnection certainty as a land value driver.

How is this different from solar or wind interconnection disputes?

Generation interconnection — for solar and wind — is governed by FERC-mandated procedures under Order 2023, which provides applicants with defined timelines, study requirements, and cost allocation rules. Industry context: large load (demand-side) interconnection for data centers typically falls under state utility commission jurisdiction and utility-specific tariffs, with less standardized procedural protection — making disputes harder to adjudicate and outcomes less predictable.
