December 15, 2025 A major proposal to convert a vacant mill in Lewiston, Maine, into a high-capacity artificial intelligence data center is poised to bring significant investment and technological infrastructure to the region, pending a crucial city council vote. The project underscores the expanding geographic footprint of AI compute demand, moving beyond traditional hubs into areas with available space and power. The development firm MillCompute LLC has proposed constructing a Tier III-certified AI data center within the currently empty Bates Mill No. 3 building in downtown Lewiston. According to a memo to city officials, the project team comprises local leadership and national experts in data center construction, operation, and finance. The plan involves utilizing approximately 85,000 square feet across the building's first two floors for the facility, which is reported to become the state's second-largest AI data center upon completion. Lewiston City Administrator Bryan Kaenrath highlighted the project's potential economic benefits, stating it is projected to generate just under $800,000 in annual tax revenue for the city and create between 20 to 30 local jobs. The final decision rests with the Lewiston City Council, which is scheduled to vote on the proposal at its next regular meeting on December 16. However, the project has already sparked community debate. A Facebook group named "Mainers against future AI data center in Lewiston" has formed in opposition, garnering over 100 members and reflecting local concerns that often accompany large-scale digital infrastructure projects. The outcome of the council vote will signal whether Lewiston joins the growing list of communities adapting historic or industrial sites to meet the surging infrastructure needs of the AI era, balancing economic development with local sentiment.
