Osiris Energy builds world’s largest small wind forest in Thailand

By Nic Sharpley | August 16, 2013

Osiris Energy

350 sets of Osiris 1.6 KW small wind turbines were installed just south of Bangkok.

South of Thailand’s capital city of Bangkok, lies a vast wetland area near the sea called Tar Chalome, which is now home to the world’s largest and tallest small wind farm. Toiling for over a year, a crew of about two dozen workers erected 350 sets of Osiris 1.6 KW small wind turbines there, which now resembles a quivering forest rising out of the wetland. Each leaf on the many tree towers is an Osiris 1.6 wind turbine with five blades that seem like tiny dancers in the wind. A temple was built specially for this small wind farm.

The wind resource in the Tar Chalome area is light to medium at best. The investors were initially skeptical about a small wind turbine solution for this area, because the large wind turbines installed in the past were not suitable for the low wind speeds of the area. The client started with a pilot project of one Osiris 1.6 on a 100-meter tower.  After a one-year test, the client was convinced that an Osiris small wind farm with distributed generation could work better than a single large wind turbine system.

The small size of the 78 kilogram Osiris 1.6 system is deceptive. The Osiris 1.6 has estimated annual energy production 3,000-3,500 kWh at 6 m/s based on real installation data. The start-up wind speed is as low as 2.4 m/s and rated wind speed is 10.5 m/s. The turbine is equipped with a top quality Ginlong direct drive permanent magnet generator.  It is an upwind machine with passive yaw control and five blades with a rotor diameter of 3.2 meters. The Osiris 1.6 only weighs 78 kilograms or 170 lbs.

The special one tower multi-turbine design, the ease of the Osiris installation, early start-up, excellent low wind production performance, and near-free maintenance, all make the Osiris an attractive solution. But most important, the investors have been pleased with the payback for this project in an unusual location: they are reducing their electricity expenditures by almost half.

This world’s largest low wind farm is a great example of a wind solution based on low speed, decentralized wind turbines for the widespread areas in the world with low wind speed.

    I feel you have found a good energy production solution. I hope you see birds nesting in the wind turbine trees soon.
    Sincerely,
    Wendy.
