Profile of PT. PLN (Persero).


The history of PLN dates back to 1945 when the government established Jawatan Listrik dan Gas under the Public Works and Energy Ministry with a power generating capacity of 157.5MW. In 1961, the name of the agency was changed with Badan Pimpinan Umum Perusahaan Listrik Negara (BPU PLN) to operate in the electricity and coke sector . In 1965, BPU PLN was dissolved and two new companies were formed--Perusahaan Listrik Negara (PLN) to operate in power generating industry with a capacity of 300 MW and Perusahaan Gas Negara (PGN) operating in gas distribution.

In 1972, the government gave the status of PLN as a public company Perusahaan Umum Listrik Negara (PLN) and under a regulation of the government No 17 in 1990, PLN was given the status as the authority in the electricity sector.

In 1992, the government allowed the private sector to operate in power generating business. In line with the policy, in 1994, the status of PLN was changed with a limited company PT Perusahaan Listrik Negara (PT PLN).

PLN is responsible for supplying the whole country of 13,000 islands with electricity . PLN divides the country into 16 working areas including Nanggroe Aceh Darussalam, North Sumatra, West Sumatra, South Sumatra, Riau, Bangka Belitung, Lampung, West Kalimantan, South Kalimanatan, Central Kalimantan, East Kalimantan, North Sulawesi, Central Sulawesi, Gorontalo, South Sulawesi, Southeast Sulawesi, West Sulawesi, Maluku, North Maluku, Papua, West Nusa Tenggara and East Nusa Tenggara.

PT. PLN, therefore, has to build power generating plants, transmission networks and distribution systems and other supporting facilities. Currently PT PLN (Persero) has a number of subsidiaries--PT. Pembangkitan Jawa Bali, PT. Indonesia Power, and PT. Indonesia Comnets Plus, PT Prima Layanan Nasional Enjiniring (PT PLN Enjiniring), Pelayanan Listrik Nasional Tarakan (PT PLN Tarakan), Pelayanan Listrik Nasional Tarakan (PT PLN Tarakan), PT. PLN Batubara, PT. PLN Geothermal, Majapahit Holding BV and PT. Geo Dipa Energi.

PT Indonesia Power (PT. IP)

PT IP was originally known with the name of PT. Pembangkit Jawa Bali I, established in 1995. Its business is to operate power plants and in other related areas. In 2000, its name was changed with PT Indonesia Power.

Currently PT. IP is the largest operator of power plants in Indonesia, having 127 units of power generating units with a total installed capacity of 8,888 MW. IP has 8 power generating business units (UBP) located in various areas in Java and Bali and one Maintenance Service Business Unit. The UBPs include UBP Suralaya, UBP Priok, UBP Saguling, UBP Kamojang, UBP Mrica, UBP Semarang, UBP Perak Grati and UBP Bali.

IP has continued to seek expansion of its power generating capacity in Java as well as outside Java such as in West Kalimantan, East Kalimantan, South Sumatra, Jambi, and East Nusa Tenggara.

UBP Suralaya

UBP Suralaya operates coal-fired power generating plants with an installed capacity of .400 MW.

UBP Priok

Apart from 2 units of gas-fired power plant (PLTG), UBP Priok operates 6 units of diesel power plants (PLTD) in Senayan operating in 1961 to supply electricity to the People's Congress (MPR) building, the Gelora Bung Karno Sport Complex and the state television station, TVRI.

In 1992, PLN in cooperation with an international consortium of ABB and Marubeni built power underground cable of 150 KV to channel electricity to the electrical relay stations of GI Plumpang and GI Ancol. Power was also channeled through high voltage air cables (SUTT) of 150 KV to Kemayoran I/II, Plumpang I/II. After the fill operation of the combined cycle power plant of PLTGU Priok synchronization was made to the Java-Bali systems.

UBP Saguling

UBP Saguling operates mainly hydro electric plants (PLTA). Development of PLTA units is in line with the government policy of diversifying sources of energy and to economize on the expensive oil. uBp Saguling has 29 power generating machines in West Java with a total installed capacity of 797.36 MW.

PT Prima Layanan Nasional Enjiniring

PT. PLN Enjiniring was established in 2002, to operate in engineering design consultancy and construction supervision.

PT. Geo Dipa Energi (PT. GDE)

PT. GDE was established in 2002 as a joint venture between PLN and state oil and gas company Pertamina. GDE operate geothermal power plants. It develops geothermal energy to produce electricity from Dieng and Patuha each having a geothermal reserve of 400 MW.

The main business of GDE is explorations and exploitations to build power plants and energy distribution facilities. Currently GDE supplies power to the Jamali (Java-Madura-Bali) transmission line .

PLTP Dieng

PLTP Dieng is a geothermal power plant in Dieng operated by GDE. The Dieng geothermal field is estimated to have a potential reserve of 300 MWe.

PLTP Dieng Unit 1 is already operational with a capacity of 1x60 MWe. The power plant has been connected with the Java-Madura-Bali interconnection. The capacity of the Dieng Unit 2 and Uni8ts 3 is being expanded to 60 MWe.

Patuha project

Patuha is located at Gunung Patuha in West Java not far from the city of Bandung. The project is developed together with Dieng Unit 1, but Patuha project has not fully been operated by GDE.

The Patuha field has an estimated reserve of 400 MWe. It is estimated to have he capacity to produce 60MWe of geothermal steam.

GDE will develop the Patuha reserve in three units--Patuha Unit 1, 2 and 3 each with a capacity of 55 MWe.

In 2009, GDE secured a loan of US$ 103 million from Bank BNI. The 11-year loan was used t to finance development of PLTP Patuha with a capacity of 55 MWe. He PLTP is expected to be operational in 2012.

Financial performance

PLN's financial performance in 2010 improved compared with the previous year. Its income from the sales of electric power rose 14.2 % that year from Rp 90.2 trillion in 2009 to Rp 102.9 trillion in 2010. The improvement of the financial performance was attributable mainly to an increase in the number of its subscribers by 2.3 million and increase in sales from 134.582 Giga Watt hours (GWh) to 147.297 GWh.

In 2010, PLN was able to meet all demand for new connections with no subscriber in the waiting list.

The profitability of the company improved as shown by the increase in operating profit from Rp 9.9 trillion in 2009 to Rp 13.3 trillion in 2010. Increase in operating profit was attributable partly to an increase in sales of electric power and rise in subsidy margin from 5% to 8%.

Growing number of subscribers require an increase in production of electric power. In 2010, PLN launched a program to end the inconvenience of blackouts in some areas in the regions. Fuel consumption, therefore, increased as shown by the rise in fuel cost from Rp 76.2 trillion in 2009 to Rp 84.2 trillion in 2010 . Operating cost rose 10.2 % to Rp 149 trillion.

Energy mix in 2010 improved from 2009 with oil fuel contribution declining from 23% to 20% while gas contribution rose from 22% to 24%. Heavier rains in 2010 resulted in greater contribution of hydropower plants to energy mix up from 7% in 2009 to 10% in 2010. The improvement in the energy mix helped offset deficiency in power supply from coal fired power plants with the delay in the completion of PLTU Indramayu, PLTU Rembang and PLTU Suralaya until April 2011. Progress has also been made in improving efficiency by reducing depreciation of networks from 9.93 % in 2009 to 9.74 % in 2010.

By Dec 31, 2010, PLN's assets were valued at Rp 369.5 trillion, up Rp 35.8 trillion or 11 % from Rp 333.7 trillion a year earlier. Fixed assets accounted for 87% of the increase especially in coal-fired power plants built under the first crash program to build coal-fired power plants with a total capacity of 10,000 MW. The assets included non current assets valued at Rp 324.4 trillion and current assets valued at Rp 45.1 trillion. Its liabilities include non current liability valued at Rp 164.6 trillion and current liabilities totaling Rp 55.3 trillion. With equity totaling Rp 149.5 trillion, its equity and liabilities of PLN totaled Rp 369.5 trillion by the end of in 2010.
