Ushering in winds of change in clean energy, Nanyang Technological University, Singapore (NTU Singapore) and ENGIE have jointly deployed the nation’s first long-span wind turbine at Semakau Landfill, which is one of several to be installed in Singapore’s drive towards sustainable energy solutions.
The turbine comes with three 10.5m long-span roto blades that produce an electrical output rating of 100 kilowatts, which is enough to power 45 four-room HDB flats. The wind turbine is also sensitive enough to generate power even with wind speeds as low as 3 metres/second, up to a maximum of 20 metres/second.
In partnership with global energy leader ENGIE, the new turbine is part of NTU’s Renewable Energy Integration Demonstrator – Singapore (REIDS) initiative being built at Semakau Landfill. Under this initiative, several hybrid microgrids will be developed in the coming years, producing enough energy to power 100 four-room HDB flats for a whole year.
REIDS project, now in its second phase, has already installed more than 4,500 sq m of photovoltaic panels, large-scale lithium-ion energy storage systems and a hydrogen refuelling station, which are already operating at the island.
Professor Lam Khin Yong, NTU’s Acting Provost, Chief of Staff and Vice President for Research, said, “The deployment of Singapore’s first wind turbine is a big milestone in the nation’s commitment in developing clean energy technologies for the region. As a leading global university, NTU is proud to support Singapore’s efforts in meeting its sustainability objectives and pave the way towards a greener future.”
Managed by NTU’s Energy Research Institute (ERI@N), the REIDS initiative is expected to attract $20 million worth of projects over the next four years, in addition to the initial $10 million investment in infrastructure at the landfill.
ERI@N’s Co-Director and REIDS’ Director, Prof Choo Fook Hoong, said: "The role here is to look at renewable energy, integrating them into microgrids, so that it can benefit not only remote islands and villages (in the region), but also urban microgrids that will benefit Singapore in the longer term in terms of a more stable and resilient power supply."
"When we look at renewable energy integration, we cannot rely entirely on photovoltaics because that will only work when the sun is out. Wind is different - you have wind at night as well... this allows us to have continuous power supply without having to increase the storage capacity, which is not that cheap today", complemented Prof Choo.
The REIDS initiative will pave the way for similar technologies to be developed and exported to serve the need for interconnected urban microgrids and remote communities in Southeast Asia and beyond. It has already attracted the interest of regional adopters such as island communities and utilities.
