The only bat-friendly control system

CHIROTECH
The only bat-friendly control system
The problem
• Chiroptera (= bats) is a protected species in many countries
=> many projects are blocked because of being in a chiroptera
area (red on the example map below)
Project area
The problem
• "Moving" wind turbines out of a chiroptera area often
reduces the production of the machines, because the
wind conditions are not optimal anymore
The idea
Chiroptera activity is limited to some very particular conditions
=> use of an algorithm defining the probability of chiroptera activity
(designed by Biotope)
How does the solution work?
Wind Farm
SCADA Server
(Wind Farm Portal)
7: When the computer
BIOTOPE, IT
(Toulouse)
determines there’s no
activity anymore, a
restart order is sent

Typical wind farm data flow:
- outside temperature
- hygrometry rate
- wind speed
- date / time
4: Email automatically
5 and 6: The Chirotech

module receives the
stop order has been
email, and stop the
received INTERNET

Currently being tested
• On wind farm Bouin (France)
• Since early 2009
• And it works well…
It really works well …
Wind Farm cut-out
Still to be done
• Analysis of the chiroptera mortality for 2009 by LPO (french
association for the protection of birds)
=> To be done at the end of the year (below: example 2008)
