Madison, South Dakota, officials are continuing discussions regarding a proposed 10-megawatt cryptocurrency mining data center by Simple Mining LLC. The project involves four modular structures on 3.73 acres of city-owned land, designed with a closed-loop liquid cooling system that would not consume water.

The Madison Board of Adjustment previously approved a conditional use permit and variance for the project on September 15. However, the Madison City Commission is still reviewing the proposal, which includes a lease agreement and an electric service agreement with Heartland Energy. Mayor Roy Lindsay has encouraged public participation in future meetings to address concerns and provide feedback.

Simple Mining's director of site development, Matt Hein, emphasized the company's efforts to minimize impact and provide economic benefits, such as increased city revenue from electricity sales, potentially leading to lower rates for other residents.

Despite these assurances, some residents, including Michael and Dawn Johnson, have submitted letters expressing concerns about constant noise and its potential impact on property values, livestock, and wildlife, stating that even standard road noise levels would be unacceptable if constant. The city previously considered a similar project from Giga Energy, which ultimately fell through due to a non-negotiable demand for uninterruptible power. The City Commission is scheduled to meet again on October 5.
