Bloom Energy shares rose as much as 15% on Tuesday after the company announced a manufacturing expansion in Fremont, California. It is acquiring a 158,000-square-foot facility. The addition will nearly double Bloom’s existing manufacturing footprint in the city to meet rising demand for its fuel cells.

The expansion is part of a broader plan to double production capacity by the end of 2026, from 1 gigawatt to 2 gigawatts. The company cited a strong order pipeline, particularly from data centers that need large amounts of power for artificial intelligence infrastructure and utilities seeking reliable on-site generation. The news was also supported by an Ameren Missouri energy plan that includes adding fuel cells.

Analysts viewed the expansion as a clear sign of a strong and growing sales pipeline. They see Bloom’s ability to deploy power solutions quickly as an advantage for technology companies facing long waits for traditional grid upgrades.
