Tripping of 2 power generating units caused Tuesday's blackout across Singapore: EMA
SINGAPORE: The blackout across multiple estates in Singapore early on Tuesday was caused by the tripping of two power generating units, one at Sembcorp Cogen and the other owned by Senoko Energy, said the Energy Market Authority (EMA) on Wednesday (Sep 19).
"Our preliminary findings show that on Sep 18, one of the power generating units at Sembcorp Cogen Pte Ltd (Sembcorp) tripped. The stability of the power system requires the electricity supply to constantly meet electricity demand. When a power generating unit trips, the other units in operation will increase their electricity supply automatically," EMA explained.
Advertisement"Subsequently, one of the power generating units owned by Senoko Energy Pte Ltd (Senoko) tripped while it was ramping up additional supply. The tripping of the two power generating units resulted in insufficient electricity supply to meet demand," it added.
About 146,500 customers were affected by the blackout.
Housing estates hit by the supply cut included Boon Lay, Choa Chu Kang, Clementi, Jurong, Pandan Loop, Aljunied, Bishan, Ang Mo Kio and Thomson.
"Investigations are still ongoing and EMA is working with Sembcorp, Senoko and their equipment suppliers to establish why the units tripped," said EMA.
