Technology Overview

Onshore wind power is a technology that generates electricity by harnessing the kinetic energy of wind to drive turbines. As wind turns the blades, mechanical energy is converted into electricity through a generator and delivered to the grid.

Onshore wind farms are typically developed in areas with strong wind resources. The primary input is wind, while the output is electricity supplied to the power system. Project capacity depends on wind conditions and installation scale.

Technical Characteristics

The nominal capacity factor of onshore wind power is approximately 35%, reflecting better energy capture compared to solar power since generation can occur both during the day and at night. However, output remains highly dependent on wind conditions and varies over time, requiring flexible system operation or complementary balancing resources. Modern turbines are designed to operate across a wide range of wind speeds, optimizing output and reducing operational losses.

Investment costs are approximately 1.37–1.65 million USD/MW. Compared to solar power, wind power has higher capital costs but benefits from higher capacity factors and more evenly distributed generation throughout the day. In the energy transition, onshore wind plays a key role in reducing emissions and diversifying the power supply.

Application in Vietnam

In Vietnam, onshore wind power has been developed in recent years, particularly in areas with favorable wind resources. Wind power projects contribute to expanding renewable energy supply and diversifying the national energy mix.
