Insights

Energy technology & capital markets analyst

Exploratory LOI; potential data center use case, no binding terms.

Plug Power disclosed a non-binding LOI on November 10, 2025 to explore using its fuel cells for auxiliary and back-up power at a U.S. data center. The language signals evaluation of a use case rather than a committed sale or deployment.

Because the LOI is non-binding and contains no commercial terms, volumes, or timelines, the near-term financial impact is indeterminate. Any activity would depend on subsequent definitive agreements and project specifics.

Investors can note the targeted application—data center resiliency—but concrete metrics (contract size, units, or schedule) are not included in this disclosure.
