In case of a power cut PLN ready with backups<\/p>\n
By Frits Pangemanan<\/p>\n
JAKARTA (JP): The State Electricity Company (PLN), currently
\nfacing public wrath for raising rates beginning this month, does
\nnot want to take any risk of power outages during the APEC
\nmeetings here and in Bogor.<\/p>\n
\"We have prepared a four-tier power supply system to prevent
\nany possible interruption of current at the venues of the APEC
\nmeetings and other buildings and strategic places related to the
\nimportant event,\" said Azis Sabarto, PLN's chief of its Jakarta
\nand Tangerang branch.<\/p>\n
He said PLN has spent the equivalent of US$8.7 million to
\ndevelop the system which will make power interruptions almost
\nimpossible.<\/p>\n
\"We have allocated another Rp 5 billion ($2.3 million) budget
\nto operate the system,\" Sabarto added.<\/p>\n
PLN has laid a reserve power cable system, which is linked to
\nthe Senayan and Karet transmission stations, at the Presidential
\nPalace in Bogor, where the APEC Economic Leaders Meeting will be
\nheld on Nov.15, the State Palace in Jakarta, the Jakarta
\nConvention Hall and the Soekarno-Hatta and Halim Perdanakusuma
\nairports.<\/p>\n
The two transmission stations are backed up by two power
\nplants; in Suralaya on the northwestern tip of West Java and in
\nMuara Karang, north of Jakarta.<\/p>\n
Under the first-tier power supply system, the Senayan
\ntransmission station is backed up by the Karet station.<\/p>\n
\"If power supply is interrupted from the Senayan station, the
\npower will be supplied within 0.3 second by the Karet station,\"
\nSabarto said.<\/p>\n
PLN also has prepared an uninterrupted power supply system, as
\nthe second tier supply, in case both the Senayan and the Karet
\nstations fail. This system will be operated pending the repair of
\nthe stations.<\/p>\n
\"If the repair work takes more than 15 minutes, we will use
\nthe third-tier supply system -- the captive generator sets
\nalready available at the five locations,\" he said.<\/p>\n
Assuming the worst possible scenario, in which even those
\ngenerators fail to work, \"we will turn to our own diesel
\ngenerators,\" he added.<\/p>\n
Safety<\/p>\n
He said that safety measures also have been taken to secure
\nuninterrupted power supply at other strategic places, such as the
\nhotels where the delegates stay, major shopping centers and such
\nplaces of interests as the Taman Mini Park.<\/p>\n
\"PLN will assign technicians at those places 24-hours-a-day to
\ncope with any possible power supply problems,\" Sabarto said.<\/p>\n
As many as 752 PLN technicians and executives have been
\nassigned especially to maintain an uninterrupted power supply
\nduring the APEC meetings in Jakarta and Bogor.<\/p>\n
The detailed safety measures are especially necessary because
\nwe anticipate heavy rains and strong winds beginning this month,
\nhe said.<\/p>\n
\"We have prepared 21 mobile power generators in Jakarta and 11
\nothers in Bogor for the event,\" he added.<\/p>\n
He expects that the power supply capacity will pose no
\nproblems at all because the Java-Bali interconnected grid has an
\noversupply of around 4,500 megawatts (MW).<\/p>\n
He estimated that the additional demand for electricity during
\nthe APEC meetings will only reach around 75 MW. PLN's subscribers
\nin Jakarta utilize only 3,500 MW.<\/p>\n
A back-up power supply system also has been established for
\nsix hospitals, Pertamina hospital, Metropolitan Medical Center,
\nPelni Hospital, Pondok Indah, Harapan Kita Hospital and Cipto
\nMangunkusumo, as well as for all hospitals in Bogor.<\/p>\n
He added that PLN also will keep special guard on the Industri
\nPesawat Terbang National (IPTN) aerospace company in Bandung, the
\nHusein Sastra Negara and Atang Sanjaya airports, the national
\nradio and television stations RRI and TVRI, telecommunications
\noffices and major hotels.<\/p>\n
According to Aziz, PLN will deploy 964 operators and
\ntechnicians and open 107 new operational posts in Jakarta for
\nserving the APEC summit. \"In Bogor, PLN will open 28 operational
\nposts and use 276 technicians during the event,\" he added.<\/p>\n
PLN also established a multiple safety system to prevent power
\ninterruption during the summit meeting of the Non-Aligned
\nMovement here in September, 1992.<\/p>",
