States Edge Wind Interconnection Agreement Filed With FERC in Amended Submission

Southwest Power Pool (SPP) formally amended and resubmitted its September 25, 2025 filing by providing an executed First Revised States Edge Generator Interconnection Agreement (GIA) on January 7, 2026. The agreement, which is part of docket ER25-3512, names States Edge Wind I LLC as the interconnection customer, AEP Oklahoma Transmission Company as the transmission owner, and SPP as the transmission provider. The document and its exhibits were submitted as the official regulatory record to the Federal Energy Regulatory Commission on January 7, 2026.

The amended filing identifies the States Edge Facility and lays out the interconnection terms, including point or points of interconnection to AEP Oklahoma’s transmission system. The attached First Revised GIA is executed and accompanied by appendices that the filing summarizes. Those appendix summaries report updates to estimated costs, milestone completion dates, operation and maintenance charges, shared facilities language, and other technical and commercial provisions. The filing also notes non‑conforming provisions and specific cost and allocation language used in the agreement that diverge from standard tariff terms.

For Texas County, the filing matters because it marks a procedural advance in the project’s path toward construction and operation. Interconnection agreements typically anticipate necessary transmission work; any required upgrades on AEP Oklahoma lines could involve engineering, construction activity, and cost-allocation decisions that affect regional ratepayers and stakeholders. Updated milestone schedules in the appendices will govern when construction could begin and when the facility might begin delivering power, while operation and maintenance charges and shared facilities arrangements will shape longer-term operating costs and responsibilities.

Regulatory review remains a key next step. The paperwork filed with FERC provides the legal and technical basis for the commission’s assessment of the interconnection, including whether non‑conforming provisions are justified. Approval would clear the way for implementation of the agreed milestones and any network upgrades spelled out in the agreement; denial or modification could require further negotiation.

Locally, residents can expect any approved project to bring a sequence of effects: permitting and construction activity that can create short-term jobs and increased demand for local services, along with longer-term property tax revenues or land-lease payments where turbines and equipment are sited. Conversely, construction and transmission work can produce temporary traffic and land-use impacts. The filing itself does not specify local siting details in these notes, but it does indicate the project is moving through the formal interconnection process that precedes those outcomes.

The First Revised States Edge GIA and its supporting exhibits form a many-page regulatory submission that establishes the terms under which this wind facility would connect to the regional grid. As regulators and stakeholders review docket ER25-3512, the updated cost allocations, milestone dates, and technical terms in the filing will determine how and when the project could influence the local economy and the regional electricity system.
