Hello,
As previously announced, we are currently constructing
our first wind farm. The goal is to be the
supplier of our own energy to all our data centers so that
we do not have to buy energy from EDF in the future, hopefully
2020.

Indeed, the electrical power is the first cost to all
datacentres, but with wind farms whose cost of raw material is 0 Euro (the wind
does not cost anything) we think we can reduce our costs by 70% within
3 to 5 years. Very interesting. All this in
a context where the cost of energy continues to increase
each year. OVH may find itself backtracking: we will cut costs for
energy. Consequence: OVH's offers in
the hosting market which will be cheaper than our competitors,
while still being profitable. This means that with the cost of
energy increasing, our competitors will reassess
their prices while OVH will not be obliged to increase
prices.

Most importantly, all this is "green" No CO2. We
are hoping to reflect the spirit of our innovations on cooling
liquid servers: no air conditioning, no wasted energy.
The PUE as close as possible to 1 (<1 if we take into account there may be some
hot neighbours). The solution which will be cheap and totally
"Green". And besides, we know can cool up to 20KW of
electrical power per rack! So a concentration of
very large servers: to host 100,000 servers
we "only" need 2300-2400 racks.

Our first wind farm will be located in Alsace. It will
consist of 8 wind turbines and will generate a total between
6MW to 7MW. These investments will be made without using
Banks who do not believe in the project. Why? Because
OVH has decided (once again) to do things
our way. We decided to look into a newly developed and patented technology
from a company in the north of France.
There was a lack of confidence for financing from banks. So, OVH has therefore decided to
lend a hand and advance the funds to build the prototype which was installed near Valenciennes
near the Toyota plant. Which can be seen from the motorway:
http://demo.ovh.net/fr/db2e221624d0b...c1bd4de458e7c/

The prototype is being validated by the standards related to
energy production from wind turbines. This
technology allows the turbine to turn
with less wind and will therefore be "more diificult"."They are smaller and comply with all the "harder" standards
in terms of height and visual impact.
The prototype is for 800KW and weighs "2 times less" than
any equivalent in the market. Validations are up to 200KW
(For security) and that power is injected into the network at a cost of €8 per/hr ...

The production of energy of course depends on wind and
speed. The wind fluctuates across a range of
powers, sometimes not too little but not too much.
If operating at 100% capacity and 100% of the time
(The theoretical case), the sale of energy would
be funded in 3 years! and after 3 years, the rest of the
time the cost would be 100% ... since there
will be no further costs. In general, we calculate the turbines profitability
based on the wind farm and on the wind in which it is installed .
Therefore we must analyse it for 1 year 24/7 to validate a field ...
It generally runs 25% of time running at 100%.

All this is very interesting. OVH has made the
Beta technology and our field is installed and
producing energy (for OVH), we will discuss with our
customers about other wind farms of this type.
The idea is proposing to invest in the establishment of a
farm and reap the benefits of this investment
for 15 years. Without banks. Just directly between the people.
