Building 1 is operational, which is assumed to be three months after the last backup diesel generators are finished. The generators were first seen to be finished July 1 from satellite imagery [(a clear image of this can be seen on July 29 via Google Earth).](https://earth.google.com/web/search/38%c2%b044%2745%2e12%22N+77%c2%b032%2716%2e47%22W/@38.7458667,-77.5379083,83.89135729a,642.01325639d,35y,0h,0t,0r/data=CjQiJgokCTo0Rh9P7TVAETk0Rh9P7TXAGX6C6a6li0VAIQ_0AAa-ik7AKgYIARIAGAFCAggBQgIIAEoNCP___________wEQAA)
