Comparing the raw tariffs for the new service locations with the actual payments for established locations (after various adjustments, bonuses, promotions, incentives,etc.) will show that there are great savings available for flexibility and inventiveness. It is not unusual to pay nothing for electricity provided that you stay below certain ceiling usage and allow yourselves to be cut off first during peaks.
Here's an example picture from an improvised Bitcoin mine that somebody just posted in the Hashfast thread
https://bitcointalk.org/index.php?topic=262052.msg8626008#msg8626008In case the picture above is removed: it shows rows of miners running with no cases but laid out on the rearranged office desks with chairs&cabinets removed. I wish I could find and post the pictures for the first data centers for Victoria's Secret (and associated clothing brands) which were assembled from desktop computers laid out in cafeteria and mini-cubicle call center locations in supposedly expensive downtown skyscrapers.
Again, while I don't have specific information about the locations mentioned here, I'm positive that there are great opportunities available for temporary, improvised locations. Just look and ask around.
