South Dakota PUC: Triple H Wind Permit Approved With 41 Conditions

• The South Dakota Public Utilities Commission approved a construction permit for the Triple H Wind project on July 9, 2019, allowing for a facility capable of generating up to 250.54 megawatts in Hyde County. The project is now operational.
• The approval came with 41 specific conditions, including requirements for addressing shadow flicker, sound levels, land restoration, ice throw, and potential impacts on whooping cranes.
• A key condition mandates the establishment of an escrow account to fund the future decommissioning of the wind project.
• The commission upheld standard notice requirements, requiring 14 days for landowners and 30 days for the commission prior to construction, despite the developer's request for an earlier start.
• The project, spanning 27,247.5 acres with up to 92 turbines, has secured power purchase agreements to supply 150 megawatts to Walmart and 48.6 megawatts to Boston University.

A particularly notable requirement imposed by the commission is the establishment of an escrow account, specifically earmarked to cover the future costs of decommissioning the project, ensuring financial responsibility for its end-of-life cycle.

The South Dakota Public Utilities Commission (SDPUC) formally approved a construction permit for the Triple H Wind project on July 9, 2019, following a regular meeting in Pierre. This significant decision paved the way for a new wind energy facility in Hyde County, designed to generate up to 250.54 megawatts of power. The approval of the South Dakota PUC Triple H Wind permit came with a comprehensive set of 41 conditions that Engie North America, the owner/operator of the Triple H Wind project, must rigorously observe throughout both the construction and operational phases of the project.

Among the specific Triple H Wind project conditions are provisions addressing potential environmental and community impacts, such as shadow flicker, sound levels, and the critical process of land restoration once construction concludes. Furthermore, the conditions meticulously detail measures to mitigate risks associated with ice throw from turbines and potential impacts on whooping cranes, a species of conservation concern. A particularly notable requirement imposed by the commission is the establishment of an escrow account, specifically earmarked to cover the future costs of decommissioning the project, ensuring financial responsibility for its end-of-life cycle. This SDPUC wind farm decommissioning escrow highlights the commission's focus on long-term environmental and financial safeguards.

The South Dakota Public Utilities Commission's decision followed a structured regulatory process that began with Triple H filing its application on February 6, 2019. A settlement agreement between the project developer and PUC staff was reached and accepted by the commission in May. However, several critical issues remained unresolved, including the aforementioned decommissioning funding, ice throw risks, and potential impacts on whooping cranes. These outstanding matters were subsequently addressed during an evidentiary hearing held in late June, leading directly to the commission's final ruling in July. State law mandates that the commission render a decision on wind energy facility applications within nine months of their filing, a timeline met in this instance.

During its deliberations, the commission also considered a request from Triple H to modify standard notification requirements for landowners and the commission, seeking to commence construction by August 1, 2019. Despite the developer's desire for an expedited start, commissioners voted to uphold established protocols, maintaining the requirement for 14 days' notice to landowners and 30 days' notice to the commission prior to construction. PUC Commissioner Gary Hanson emphasized the importance of consistency and honoring precedents in such decisions, noting that while he understood the project's need for a single construction season, proper notice for citizens and communities was paramount. This adherence to established timelines is a key aspect of renewable energy project permitting SD.

The approval process for the Triple H Wind project was notably characterized by strong community engagement and support. A public input hearing held in Highmore in March saw no parties seeking to intervene in the docket, a testament to the developer's proactive efforts. PUC Chairman Chris Nelson reflected on the unusual level of community participation, suggesting it indicated that the applicant had effectively addressed local concerns prior to the formal hearing. PUC Vice Chairperson Kristie Fiegen further commended the collaborative spirit between the applicant, the Highmore community, and commission staff, describing the outcome as a "win-win situation."

The Triple H Wind project is operational across a substantial 27,247.5-acre area, encompassing up to 92 individual wind turbines. Beyond the turbines, the project footprint will include essential infrastructure such as access roads, underground collector lines, fiberoptic cable, a collection substation, a permanent meteorological tower, a 345-kV interconnection switching station, a sonic detection and ranging unit, and an operations and maintenance facility. Upon completion, the facility has secured two power purchase agreements: 150 megawatts will be supplied to Walmart, and an additional 48.6 megawatts will go to Boston University, with the remaining 52 megawatts available for other distribution. This large-scale South Dakota wind energy approval represents a significant addition to the state's renewable energy portfolio.

Lawyers advising renewable energy developers in South Dakota should note the specific conditions imposed by the PUC, particularly the requirement for a decommissioning escrow and strict adherence to established notice timelines for landowners. This case provides insight into the regulatory expectations for environmental mitigation and project scheduling in the state.
