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 in 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 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 water cooling of the servers: no air conditioning, no wasted energy. The PUE as close as possible to 1 (<1 if we take into account that we heat up our neighbours). Solutions which will be cheap and totally "green". And besides, we know how to cool up to 20KW of electrical power per rack! So a very big concentration servers: to host 100 000 servers we "only" need 2 300-2 400 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 having aids from 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 by 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:
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 placed on a "more difficult" field. They are smaller and comply with "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 gain would be 100% ... since there will be no further costs. In general, we calculate the turbine's 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 the time 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.
