Cassville Data Center Proposal
Operator not disclosed. Withdrawn
An undisclosed developer, working through Grant County's economic development office and drawn by the nearby Cardinal-Hickory Creek transmission line, scouted about 500 acres in the town of Cassville for a data center pitched at 1 to 2 billion dollars in investment and 50 permanent jobs. After months of public meetings and a rally that drew hundreds of opponents, the developers stopped responding to the county in mid April 2026, and the project was considered dead by late May 2026. Cassville voters separately authorized the town board to ban data centers through zoning for up to two years.

What it would mean nearby
Transmission upgrades like this are typically billed to every electric customer in the state through transmission charges, not just to the data center that made the new line necessary, which is why the cost allocation question matters for ordinary bills even outside the four counties involved.
