Governor Mills Vetoes Maine’s First Data Center Moratorium Over Jay Project Exemption

Context Maine lawmakers passed LD 307, which would impose a temporary pause on new data centers while the state creates a coordination council to study impacts on the grid, environment and ratepayers. The bill emerged amid growing concerns that large‑scale AI data centers could drive up electricity costs. Mills had previously signaled agreement that a moratorium is warranted but insisted the Jay project be excluded. The proposed council would have been tasked with evaluating grid upgrades, renewable energy integration, and potential tax revenue from data center operations.

Key Facts - Mills said a moratorium is appropriate but the final bill fails to allow a specific project in Jay that has strong local support. - Recent U.S. Energy Information Administration data show data centers could increase Maine electricity rates by up to 36 %. - Representative Melanie Sachs argued the veto rejects the governor’s own task force advice and opposes the majority of Maine residents.

What It Means The veto preserves the Jay redevelopment, which developers say will reuse existing industrial infrastructure and avoid the ratepayer impacts cited in the moratorium. However, critics contend that pausing only the broader moratorium leaves the state vulnerable to future rate hikes and environmental strain from unchecked data center growth. Supporters of the Jay project argue that its localized benefits outweigh the statewide risks highlighted by the moratorium. The Legislature can override the veto with a two‑thirds majority in both chambers, a threshold that remains uncertain. What to watch next: whether lawmakers pursue an override or shift to alternative regulations that balance job creation with energy affordability.
