An official of the State Electricity Board (PT PLN) for Bali blames two blackouts in as many days to disruptions on two 150 KV high-voltage lines causing momentary power outages affecting the entire island.
The power interruptions took place on Saturday and Sunday, August 20 and 21, 2011. The first interruption on Saturday, August 20th happened six separate times in quick succession at a single location when kites in a local kite-flying competition at Banjar Biaung in east Denpasar short-circuited the high-voltage lines.
According to the State new agency Antara, the kites have the potential of causing lasting damage to Bali’s electrical system, reducing the life of PLN’s power equipments. When similar disturbance occur, the official warned, these will be follow by interruptions throughout the Bali power grid. The interruptions also cause problems at power generating centers in Denpasar at Pesanggaran and at power generating stations as far away as Gilimanuk.
The first wide-spread outage took place on Saturday, August 20, 2011 at 14:54 on Line #1 between Pesanggaran-Sanur. Later, on the same day, a second interruptions occurred at 16:22 on transmission line #2 connecting Sanur and Gianyar.
Power workers were compelled to turn off power supply to Padang Galak, Banjar Biaung, Jalan Soka, Jalan Supratam Timur, Jalan Merak and Banjar Tangtu Kesiman for 1.5 hours due to the rapid and repeated assault on high power lines from large kites.
The next day up to four more interruptions happened in the same area between 13:45 and 17:05. And, again, to prevent more widespread problems PLN officials took the precautionary step of turning off the power for three hours to selected areas of the island in close proximity to kite competition.
PLN officials are asking the public not to fly kites in close proximity to power lines.
