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.
At 14 storeys high, the turbine comes with three 10.5-metre long-span rotor blades that produces an electrical output rating of 100 kilowatts, enough to power 45 four-room HDB units a year.
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 French multinational electric utility company 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.
Along with the wind turbine, each of the hybrid microgrid will integrate with various renewable energy sources such as solar, tidal, diesel, and power-to-gas technologies. Currently, over 4,500 square metres of photovoltaic (PV) panels, large-scale lithium-ion energy storage systems as well as a hydrogen refuelling station are already operating on the island. Each of the microgrid is expected to produce stable and consistent power in the half-megawatt range, suitable for small islands, isolated residential areas, and emergency power supplies. The microgrids will eventually occupy over 64,000 square metres of land or roughly about nine soccer fields.
