New reports from Northwest utilities confirm that data center growth is a primary driver of rising natural gas consumption across the region, adding strain to existing pipeline and generation infrastructure. The findings follow similar disclosures from Pacific Northwest utilities earlier in June 2026, indicating the trend is widespread rather than isolated. Analysts warn that continued buildout of AI-focused data centers could accelerate fossil fuel dependence in states that had planned to reduce gas reliance. Utility commissions in Oregon and Washington are expected to address demand forecasting rules in upcoming regulatory proceedings.
