A wind turbine obtains its power input by converting the force of the wind into a torque acting on the rotor blades
The amount of energy which the wind transfers to the rotor depends
- on the density of the air- the rotor area- and the wind speed.
In other words you can get more energy:
- the "heavier" the air- the “bigger” the rotor- the “higher” the wind speed

12 Steps to install a wind farm
1. WIND ASSESSMENT... available wind data will be used to estimate how much
energy the wind farm will produce.
2. WIND FARM DESIGNWind data combined with topographical information to design
the wind farm..... to model wind flow, ... turbine performance... sound levels ... to optimize the location of WTG ... design the access roads... turbine foundations ... local electric network... grid connection
15
3. ENVIRONMENTAL STUDY... to identify any impacts on landscape, plants and wildlife,
soil and water, land use, aviation, telecommunications, etc.
4. LAND ACQUISITION... to negotiate “option” agreements to use land
5. PERMITTING AND PUBLIC CONSULTATION... seek municipal, provincial and federal permits before the
project can go ahead. ... meet the local communities to present the project, solicit
their feedback and seek community support.
12 Steps to install a wind farm
16
6. ECONOMIC AND FINANCIAL ANALYSIS… demonstration of the economic viability of the project to raise
the funds… estimate the cost of turbines and their installation, as well as
roads, electrical system, operation and maintenance, etc.... estimate the income by using the energy production of the
wind farm over the lifetime of the project
7. MANUFACTURINGWTG parts are manufactured and pre-assembled into the main
components at the factory and shipped to the wind farm site where the final assembly will take place.
12 Steps to install a wind farm
17
8. SITE PREPARATIONThe wind farm site will be prepared before the WTG will arrive to
site. ... access roads, clear the areas where turbines will be erected... preparation of the foundations (do the excavating; installing
the formworks; pouring concrete)
9. CONSTRUCTIONAfter arrival of all components, the assembly can take place by
using a crane to erect the tower and install the nacelle and rotor with its hub and blades. Same time the electrical works will be performed

10. COMMISSIONINGThe wind farm will tested before becoming fully operational.
11. OPERATION AND MAINTENANCEA variety of skill sets are required to ensure the effective operation of a Wind Farm (activities be performed on a regular basis throughout the project’s, monitoring and analyzing performance, performing preventive maintenance and repairs on the turbines)
