Alcoa to Sell Idle Aluminum Smelter to NYDIG for Bitcoin Mining Infrastructure

Gate News message, April 19 — Alcoa, the U.S. aluminum producer, is set to complete a transaction with bitcoin miner NYDIG to sell its idle Massena East aluminum smelter in New York, with the deal expected to close by mid-2026. The facility, which has been dormant since 2014, is equipped with a substation, transmission lines, and high-capacity grid access, and can utilize hydroelectric power from the New York Power Authority, making it attractive for bitcoin mining and data center operations.

The sale reflects a broader trend in the U.S., where retired industrial sites are being repurposed for bitcoin mining, artificial intelligence, and high-performance computing infrastructure.
