Relevant question. I got a little excited.
1 server consumes around 100 Wh, the power installed to supply 100.000 servers is therefore 10.000 KW. You can heat a house, not too well insulated with 5 to 10 KW. (power, always)
It is therefore 1000 houses that such a center could heat.
Another way to calculate:
10 MW X 24 h = 240 MWh per day
divided by an average of 35 KWh / house
it's even more.
That said, I agree that installing 2000 server groups and all the mess that goes with it certainly costs more than grouping them in a single building.
On the other hand, the energy dissipated by a center such as Google Ghlin (Mons, Belgium) could certainly be partially used in district heating in the form of hot water
and 10 MW is not one of the biggest.
below 20 MW for an OVH site.
OVH doubles the electrical capacity of its infrastructures
05 May 2015 / OVH website
Faced with the explosion of cloud computing, Big Data, connected objects, and the need to offer increasingly powerful and efficient servers, OVH doubles the electrical capacity of its infrastructure in Roubaix. A major project in two respects: the electrical power supplied and the nature of the work undertaken, since the new high-voltage lines pass under the Roubaix canal, via a directed drilling. This site is also essential for the company, whose energy is the main raw material.
After announcing the construction of the OVH Campus, which will be launched this summer on land adjoining the Roubaix Valley, OVH has embarked on a project of an unusual scale. The leader in Digital as a Service, including the roubaisien site currently has an electrical capacity of 17 MW and will increase it by 20 MW, the equivalent of the energy required for a city of 25 inhabitants. "With an additional 000 MW, we can double our infrastructure in Roubaix", explains Lionel Deny, data center operations manager. “We will be able to support our growth as well as that of our current and future customers. What to look at the future serenely.
For this new connection, sheaths of electric cables leave an ERDF source substation located in Wattrelos, and join the Roubaix Valley more than 1,5 km further, where a delivery station will be installed. Over the major part of the route, the two 20 volt cables pass through trenches dug in the roadway. The main challenge of this project consists in crossing the Roubaix canal which separates the Wattrelos substation from that of OVH, limiting the risks and without disturbing the environment.
A spectacular technique
This is where directed drilling comes in, carried out by ERDF and the company FTCS Forage: a 200-meter tunnel of around forty centimeters in diameter is dug under the canal, through which the sleeves will pass.

This project is part of a vast project to increase the electrical power of OVH infrastructures, since the data centers of Gravelines and Strasbourg will also see their capacity increase by 50 MW and 20 MW respectively by the end of 2016.
