Project overview

About the Project

The Cayuga Data Campus is a modern research and technology hub located on the former Cayuga Power Plant site. The project revitalizes a long-standing industrial property — once dedicated to utility-scale energy production — and transforms it into a center for advanced digital processing and research innovation.

Purpose-built for heavy-duty, high-reliability operations, the site offers a unique opportunity to repurpose existing infrastructure for modern needs. By reusing established assets rather than developing new greenfield land, the Cayuga Data Campus promotes sustainable growth while preserving the region’s agricultural and environmental character.

Project Highlights

  • Redevelopment of ~180 acres (less than half the site), with phased buildout of 50 MW in 2026 and expansion to 138 MW, as approved by NYISO.

  • Located in Western NY, where ~90% of grid electricity is zero-carbon and substantial surplus power is available.

  • More than 500 construction jobs expected during buildout and ~100 permanent skilled positions once operational.

    See letters of support from those building our community’s future.

  • Initial operations targeted for late 2026, with staged buildout through 2028/2029.

    See our Project Tracker for more info.

  • Millions in new property tax revenue expected, plus a $100,000 annual community fund to support schools, parks, and local initiatives.

    New York’s Just Transition Working Group has identified former coal plant sites like Cayuga as ideal for reuse, particularly for data centers that bring jobs, investment, and tax growth.

  • Designed for long-term (10+ years) hosting agreements with leading global technology companies.

CAYUGA DATA CAMPUS:

A CLEAN FUTURE FOR LANSING

Responsible Development

  • Although the site retains a legacy water intake from its coal plant days, the new data campus will not draw from the lake for cooling - it will use a closed-loop system requiring only a few gallons of utility water daily.

  • Advanced cooling technology keeps sound levels below 55 dBA – about the volume of a normal conversation or household refrigerator – ensuring no noise impact at the property line.

  • Incorporates LED lighting, demand-response capability, and potential integration with adjacent planned solar and battery storage projects.

  • Converts a long-idle industrial property into productive use, aligning with state clean energy and economic development goals while avoiding new land disturbance.

  • As part of the site’s transformation, TeraWulf plans to demolish the former power plant stack at Cayuga, a visible step toward retiring legacy infrastructure and fully transitioning the property to a modern, zero-combustion operation.
