Apple is planning to build an additional “tactical datacenter” at its facility in Maiden, North Carolina, according to a report by the Hickory Daily Record. The new building will be smaller than the previous addition, coming in at only 14,246 square feet, and will house additional server hardware along with new offices.

The previously-constructed “tactical datacenter” is around 21,000 square feet. The datacenter is powered by a combination of solar energy from a 100-acre solar farm and a much smaller biogas fuel cell installation nearby.
