Maine's legislature has passed a temporary moratorium on the construction of large data centers through November 1, 2027, making it the first state in the US to enact such a ban. The move is intended to allow the state to study the environmental impact of these energy-intensive facilities.

Why it matters

Data centers have become increasingly common across the US, but their energy consumption and environmental footprint have raised concerns in many communities. Maine's moratorium reflects growing scrutiny of the data center industry and the desire to better understand and mitigate its effects on local resources and infrastructure.

The details

The moratorium applies to data centers larger than 20,000 square feet. It will give Maine time to develop regulations and standards for the siting, construction, and operation of large data centers. Supporters say the pause is necessary to assess issues like water usage, power grid impacts, and effects on the state's renewable energy goals.

  • The Maine legislature passed the moratorium on April 16, 2026.
  • The moratorium will remain in effect until November 1, 2027.
