4. 2026-06Cancelled

   Sentinel Data Centers withdrew from the Androscoggin Mill project and halted work in June 2026 (after Gov. Mills vetoed a statewide 20MW+ data-center moratorium that had been intended to protect it). Per the JGT2 mill-redevelopment team, the site itself is 'not dead' — the 82MW (expandable) power infrastructure and rail access remain, and JGT2 is seeking a new data-center operator or industrial tenant.

Source notes

Sentinel Data Centers LLC is headquartered in New York City. JGT2 Redevelopment purchased the former Pixelle Specialty Solutions mill in December 2023. ~425,000 sq ft of obsolete mill buildings demolished; paper machines shipped to Pakistan. In June 2026 Sentinel notified JGT2 of intent not to move forward; no permits were issued and no groundbreaking was held. JGT2 is seeking other operators for the site.

On-site solar generates up to 150MW; facility draws no more than 25MW from grid on cloudy days. Maine PUC approved use of on-site hydroelectric power. Cooling system proposed ~300,000 gal/day of Androscoggin River water (less than 1% of former mill usage).
