Wind power is one of the fastest growing renewable energy technologies in today's world.
As a result of wind mapping in Sri Lanka, many areas with potential wind resources have been identified to generate energy. The main wind season is from May to September and the secondary wind season is from December to February.
The National Renewable Energy Laboratory (NREL) of the United States of America has identified nearly 5,000 km of windy areas in Sri Lanka with excellent wind resources potential. About 4,100 km of the total wind area is land and about 700 km is lagoon. Windy land covers about 6% of the total land area of Sri Lanka (65,600 km2).
How does wind power generate electricity?
Wind is used to generate electricity utilizing the kinetic energy created by the moving air. It is converted into electrical energy by wind turbines or wind power conversion systems. The wind first strikes the plane of the turbine, causing it to rotate and turn the turbine attached to it. It converts kinetic energy into rotational energy by moving a shaft connected to a generator and electrical energy is generated through electromagnetism.
The wind farms, which are currently established in Sri Lanka are,
Hambanthota
Ambewela
Mannar
Mampuri
Nirmalapura
Seguwanthiv
Wallimunei
Madurankuliya
Are you aware of the largest wind farm in Sri Lanka?
Thambapavani Wind Farm or Mannar Wind Farm is the largest wind farm in Sri Lanka with a capacity of 103.5 MW and an estimated investment of US $ 200 million. Considering the electricity capacity generated by this project, it is predicted that 2,000 million liters of diesel could be saved in 20 years. Moreover, the Ceylon Electricity Board expects to generate 375 MW of electricity from the Mannar Wind Farm from 2018 to 2025 as part of an effort to increase power generation from non-conventional renewable energy sources.
Once such wind farms meet the growing demand for electricity in Sri Lanka, the surplus electricity generated by the wind sector can be used for export to India. Simultaneously, foreign exchange can be saved by drastically reducing the amount of fuel imported into the country.
Today, the importance of implementing those projects that offer greater environmental and economic benefits to the country in the long run is more emphasized than the conventional energy sources. Therefore, it is our utmost hope to see a greener Sri Lanka emerge with such projects.
This marks the end of an article informing you of the unwavering support of all the wind farms, including Thambapavani, in overcoming the energy crisis in Thambapanni, which has been a foreign attraction since ancient times. Thank you for staying with us until the end.
Will the contribution of solar, water and wind energy be sufficient to meet our energy demand? Or what might be the next contributing force? Your guess may be correct. We look forward to share with you the potential of Biomass Energy as the next stop on our journey in search of regeneration. What is biomass? How does it contribute? Are you ready to learn all about this? If so, I invite you to stay tuned with Green Pulse until our next article.
