Antora Energy has leased a 294,000-square-foot industrial building at 475 Sycamore Drive in Milpitas, developed by Prologis and completed in 2026. Cushman & Wakefield and JLL scouted tenants for the space, and Prologis confirmed the building has been leased.
Why it matters
The lease reflects Antora Energy's effort to scale its thermal energy storage technology as demand grows from data centers and new industries. The Milpitas site adds to the company's manufacturing footprint following its San Jose expansion.
The 294,000-square-foot building can handle up to 4,000 amps of power, expandable to 8,000 amps, and includes parking for 225 employee vehicles. Whether the company will expand, relocate, or do both at the site has not been disclosed.
