Chattanooga's airport is now 100% solar powered
The solar farm is expected to save the airport millions over the following decades.
- Tennessee's Chattanooga Metropolitan Airport recently completed construction of a 2.74-megawatt solar farm.
- The system includes battery storage that enables it to continue operating without constant sunlight.
- Airport officials hope it will serve as a model to other airports.
Tennessee's Chattanooga Metropolitan Airport recently became the first U.S. airport powered by 100 percent solar energy.
Started in 2010, the $10 million microgrid project includes a 2.74-megawatt solar farm that's the size of about 16 football fields, as well as battery storage technology that allows the system to run off the grid.
