There is a common belief you can't find a Google Data Center using Google Maps. Well here is the Google Lenoir, NC data center at 708 Lynhaven St SW, Lenoir, NC. Data Center friends estimate the power to be 10 megawatts for the building maybe 15 max.
I found the address here, but Lynhaven is misspelled.
This one was in Lenoir, N.C., nestled in the rolling hills of Caldwell County at 708 Lynnhaven St. Never heard of it? That's okay. Google likes it that way, nice and secretive. For perspective, Lenoir is about 70 miles northwest of Charlotte.
Using Bing Maps you can see what the site looked like before construction.
The red circled area shows where the substation will go. Here are substations added to the site.
Here is a closer view of the data center.
The resolution is quite good and you can see the construction is not complete.
Mapquest shows the building further along with cars at the support building.
South of the site looks like another data center being built.
