Soluna Files to Build 112MW Data Center Building in Willacy, Texas

By: IDCNOVARegion: North America
AI and cryptocurrency data center developer Soluna has filed plans to construct a 112MW data center facility in Willacy County, Texas, marking another significant expansion of the company's renewable-energy-powered infrastructure portfolio in the state.

According to a filing with the Texas Department of Licensing and Regulation, the project—dubbed Project Kati II—will comprise a single building totaling 471,884 square feet (43,839 square meters). The filing states that construction is expected to cost approximately $471.8 million, with the facility to be privately funded on private land for private use. No timeline for construction was provided in the filing.

The project was first reported in January, with the data center expected to be developed in partnership with Metrobloks. Soluna subsequently confirmed that a definitive joint venture agreement was signed on June 3.

Project Kati II appears to be an extension of the company's existing Project Kati I data center, which has a planned capacity of 166MW at full buildout, with 83MW allocated for its first phase. Initial energization of Kati I began on February 9, 2026, and Phase I was completed in September 2026. That facility is connected to the 273MW Las Majadas Wind Project, which serves the site behind the meter.

Soluna operates as a cryptocurrency mining firm that utilizes renewable energy projects as its primary power source. The company currently has a total operational capacity of 192MW and 11 data center sites in various stages of development. These include the 187MW Project Rosa site in Texas; the 50MW Dorothy I A and B facilities, along with the 48MW Dorothy II, both also in Texas; Project Sophie, a 25MW data center in Kentucky; and the 2MW Grace site in Texas.

In August, Soluna acquired a 397-acre plot in Briscoe County, Texas, where it plans to build its Project Dorothy III data center. That campus is expected to have a capacity of up to 300MW and will sit adjacent to the existing Dorothy I and II projects. The Dorothy III facility is expected to be powered by renewable energy, located next to the 150MW Briscoe onshore wind farm that the company purchased in April.

The continued expansion of Soluna's Texas footprint underscores the growing intersection of cryptocurrency mining and AI workloads with renewable energy infrastructure, as developers increasingly seek to co-locate high-density computing operations alongside dedicated power generation assets to manage costs and sustainability goals.
