SunEdison Builds U.S. Defense Department’s Largest Solar Plant

SunEdison Inc., the solar developer and polysilicon supplier formerly known as MEMC Electronic Materials Inc., completed the U.S. Defense Department’s largest solar installation.

The 16.4-megawatt project on Davis-Monthan Air Force Base, southeast of Tucson, Arizona, will save the base $500,000 annually for the next 25 years, St. Peters, Missouri-based SunEdison said today in a statement.

The solar farm will supply 35 percent of the base’s electricity, the equivalent of powering more than 5,000 homes, according to the statement. The Air Force wants to generate 25 percent of its energy from renewable sources by 2025.

SunEdison in April received a $35 million loan to construct the solar farm.
