Montana signs onto data center energy cost protection pledge

HELENA, Mont — Gov. Greg Gianforte is backing a new effort to keep data centers from driving up Montanans’ power bills.

This week, Gianforte announced Montana is signing on to the Ratepayer Protection Pledge — an initiative endorsed by President Trump.

Several major technology companies like Amazon, Google, Meta, Microsoft, OpenAI, Oracle, and XAI first signed the pledge back in March.

The pledge comes as data center development continues to grow — raising questions about how much new energy will be needed and who will pay for it.

NBC Montana spoke with Julia Haggerty, professor of geography and department head of earth sciences at Montana State University, about whether Montana’s power grid is ready for that growth.

“Not without resolution of significant transmission bottlenecks and massive amounts of new generation. So, while our grid is adequately, relatively adequately equipped to serve the needs of our current load base, it’s definitely not equipped to accommodate the new demands without a lot of expansion,” she said.

According to the pledge, data center developers will pay for new power generation, and infrastructure needed to support their operations.

“It does align with ongoing regulatory efforts to ensure that the cost of new generation associated with data centers is borne by the developers of those data centers and not customers,” Haggerty said.

The governor’s office says Gianforte’s support of the pledge is designed to encourage responsible data center investments while protecting Montana ratepayers from long-term costs.
