What are some considerations in implementing a wind farm?

2.2. Economic considerations

  • Capital cost. Construction, electrical connection, grid connection, planning, wind turbines, approvals, utilities and management are the main components of capital cost for wind farm projects (Lee et al., 2009).
  • Land cost.
  • Operational and management cost.
  • Electricity market.
  • Incentives.

What is the most important factor to consider when installing a wind farm?

Off course, most limiting factor for installation and use of wind turbine is the wind speed available in the particular area. The decision about the installation of wind turbine is taken on the basis of mean or average wind speed of the particular area.

What are the main considerations in selecting a site for wind mills?

Some of the main site selection consideration are given below:

  • High annual average wind speed:
  • Availability of anemometry data:
  • Availability of wind V(t) Curve at the proposed site:
  • Wind structure at the proposed site:
  • Altitude of the proposed site:
  • Terrain and its aerodynamic:
  • Local Ecology.

Can wind farms be built on water?

Wind turbines have been constructed in water since the 1990s, but they can only be fastened to the ground in water depths of about 200 feet. The floating turbines in Scotland, however, are anchored at 255 feet, and they can be rigged at depths of over 2,600 feet.

Which factors are important during design of wind turbine?

Rotor Blade Length – Three factors determine how much kinetic energy can be extracted from the wind by a wind turbine: “the density of the air”, “the speed of the wind” and “the area of the rotor”.

Does windmill affect groundwater?

What impact can a wind farm have on groundwater? The development of a wind farm has the potential to impact on groundwater quality, groundwater quantity and/or the established groundwater flow regime.

What are 4 factors that determine where a windmill can be placed?

The factors most likely to affect turbine location are:

  • Optimisation of energy production;
  • Visual influence;
  • Noise; and.
  • Turbine loads.

What are the key characteristics of a good wind site?

Favorable sites include the tops of smooth, rounded hills; open plains and water; and mountain gaps that funnel and intensify wind. Wind resources are generally more favorable for electricity generation at higher elevations above the earth’s surface.

How are wind farms built in the sea?

While most offshore wind turbines are anchored to the ocean floor on fixed foundations, limiting them to depths of about 165ft, floating turbines are tethered to the seabed by mooring lines. These enormous structures are assembled on land and pulled out to sea by boats.

What are the factors to be considered in design of a turbine?


  • 1 Aerodynamics.
  • 2 Power control. 2.1 Stall. 2.2 Furling.
  • 3 Other controls. 3.1 Generator torque. 3.2 Constant torque angle control. 3.3 Yawing.
  • 4 Turbine size. 4.1 Low temperature.
  • 5 Nacelle. 5.1 Gearbox. 5.2 Generator. 5.3 Gearless.
  • 6 Blades. 6.1 Blade design. 6.2 The hub.
  • 7 Tower. 7.1 Height. 7.2 Materials.
  • 8 Grid connection.

How are wind farms designed?

Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.

How do wind farms affect water quality?

A wind energy project can impact surface water and groundwater in several different ways, including the use of water resources, changes in water quality, alteration of the natural flow system, and the alteration of interactions between the groundwater and surface water.

How does wind energy save water?

Over the course of a year, these wind turbines supply around 7% of Texas’s electric power needs. They also save the state millions of gallons of water because wind turbines require virtually no water to generate electricity.

What is the ideal location for a wind farm?

The best places for wind farms are in coastal areas, at the tops of rounded hills, open plains and gaps in mountains – places where the wind is strong and reliable. Some are offshore. To be worthwhile, you need an average wind speed of around 25 km/h.

How do you pick a wind farm location?

Although it may seem obvious, it is important to note that locations such as the bottom of a hill or inside a valley are not good sites for a wind turbine. The best locations in terms of wind resource are typically high on mountains, in large open fields, or on the edge of bodies of water.

What type of platform should be used for offshore wind turbines in very deep waters?

4. Offshore Wind Turbines Can Float: Several companies are developing innovative floating offshore wind platforms for use in deep waters. Three kinds of floating platforms are spar-buoy, tension leg platform, and semi-submersible. About 75% of projects plan to use semi-submersible platforms.

How deep are windmill foundations?

A typical slab foundation for a 1 MW turbine would be approximately 15 m diameter and 1.5 – 3.5 m deep. Turbines in the 1 to 2 MW range typically use 130 to 240 m3 of concrete for the foundation. Multi-pile foundations are used in weaker ground conditions and require less concrete.

What are basic designs of wind turbines?

There are two basic types of wind turbines:

  • Horizontal-axis turbines.
  • Vertical-axis turbines.

Can wind turbines pollute water?

Wind turbines do not release emissions that can pollute the air or water (with rare exceptions), and they do not require water for cooling. Wind turbines may also reduce the amount of electricity generation from fossil fuels, which results in lower total air pollution and carbon dioxide emissions.

What are some disadvantages of wind energy?

Some of the main disadvantages of wind energy include unpredictability, it is a threat to wildlife, it creates low-level noise, they aren’t aesthetically pleasing, and there are limited locations suitable for wind turbines.
