Power generating industry in Indonesia.

1. Backgrounds

Indonesia is facing crisis in electric power supply. Almost the entire areas including Java-Bali, the country's business center, are suffering the inconvenience. Java and Bali account for 77% of power consumption in the country.

With economic growth of around 5%-6% power requirement grows 7%-8% a year as against production growth of only 3% per year. New power generating plants have not contributed significantly to supplying capacity since 2006. As a result shortage in supply which will potentially cause a drag on economic development.

Power requirement has been fast in the country with the growing industrialization, but the surge lately in the requirement came with many manufacturing companies formerly using oil fuels (BBM) chose to use PLN electricity to generate energy after the surge in BBM prices.

The shortage in supply is also attributable to many power plants being too old and inefficient. In addition the process of production in a number of large power plants has been interrupted. In 2007, power supply from PLTU of Tanjung Jati B declined as a result of delay in supply of coal to that power plant. The delay was caused by bad weather forcing postponement of coal shipments from outside Java.

Interruption in the process of production was also faced by the PLTU of Suralaya because of trouble in the transformers of its Unit V. Troubles were also faced by PLTGU of Cilegon over shortage in gas supply, PLTU of Gresik also over gas supply deficit. Decline in power output was also recorded by IPP (Independent Power Producers) on technical trouble faced by PLTU of Cilacap, PLTGU of Cikarang, PLTP of Drajat III, PLTP of Dieng and PLTA of Jatiluhur.

The past several years, have seen uncertainty in domestic gas supply resulting in delay in the construction of gas fired power plant projects. A number of oil fired power plants, which were already converted into gas fired power plants were forced to use oil fuel again.

In a bid to cope with deficit in power supply in the country, the government has launched its first crash program building coal-fired power plants with a total capacity of 10,000 MW. The program is expected to be fully completed in 2010. Energy and Mineral Resources Minister Purnomo Yusgiantoro said Indonesia will need still need 35,000 MW more power until 2015 the Minister, therefore, encourages development of renewable energy and asks IPP to accelerate development of their projects.

The government has tried to cope with shortage in power supply by issuing regulation on operating hours of television broadcasting stations, calling on government offices to economize on electricity. The government through PPLN even forced manufacturing companies to change part of their operating hours from normal working days to Saturday and Sunday when PLN normally has idle capacity.

2. Management of electric power system in Indonesia

In line with the Law no 15/1985, PLN is responsible for electricity procurement in the country, therefore, controls power production and distribution systems. PLN has established interconnections systems in some parts of the country Java Bali system, southern Sumatra interconnection system (covering part of Riau, West Sumatra, Jambi and South Sumatra), Northern Sumatra interconnection (covering North Sumatra and Aceh). Other islands or parts of the country have not been fully covered by interconnection systems.

Java-Bali Interconnections

The Java-Bali interconnection is the largest system in the country connecting various power generating plants and load centers in Java, Madura and Bali. The system has a total capacity of 22,236 MW with transmission system of extra high voltage cable of 500 KV, high voltage cable of 150 KV and low voltage cable of 70 KV.

Transmission system of extra high cable of 500 KV has connected all power plants in Java. The transmission cables extend along the northern coastal areas of Java supported by ones in its southern areas. The interconnection system is managed by PLN Penyaluran dan Pusat Pengatur Beban (PLNP3B) of Java-Bali.

The power plants in Java are all under control of PLN's subsidiaries PT Indonesia Power and PT Pembangkit Jawa Bali (PT PJB).

PT. Indonesia Power controls 8 Units of Generating Business--Suryalaya (3,400 MW), Tanjung Priok (1,343.56 MW), Semarang (1,469.26 MW), Tanjung Perak (561.83 MW), Bali (324.82 MW), Kamojang (360 MW), Mrica (819 MW), and Saguling (797.36 MW).

The Suralaya business unit has 7 units of coal fired power plants (PLTU). The first four units each has a capacity of 400 MW and Units 5, 6 and 7 each has a capacity of 600 MW or a total of 3,400 MW.

PT Pembangkitan Tenaga Listrik Jawa-Bali II or now known as PT. PJB was established in 1995. PJB has 8 power plants with installed capacity of 6,526 MW with assets valued at Rp41.5 trillion. PJB with 2,203 workers has become a world class power producer. Six of its power plants--Gresik (2259 MW), Muara Karang (1208 MW), Paiton (800 MW), Muara Tawar (920 MW), PLTA of Cirata (1008 MW), PLTA of Brantas (281 MW) meet international standards in capacity, quality, effectiveness and service.

Sumatra electric power system already integrated

With the completion of the 102 kilometer 150 KV transmission system between Rantau Prapat-Kota Pinang-Bagan Batu in July 2007, the interconnections system in the northern part of Sumatra has been connected with the system in the southern-central part of that island.

The system in the southern-central part will supply 70MW of its excess in power supply to the northern part of that island. The southern-central system has an excess in capacity of 100 MW.

The two interconnections systems are connected with a 150 KV transmission cable from Bandar Lampung to Banda Aceh spanning a distance of 3,000 km. Power distribution in Sumatra, therefore, has improved. The integration, however, has not fully done away with the power deficit in the northern part of Sumatra. Most of power plants in that region are relatively small in capacity while power requirement is growing fast.

Electric Systems in Other Islands

In Kalimantan interconnections have been built between Central Kalimantan and South Kalimantan. Work is still underway to establish interconnections between South Kalimantan and East Kalimantan. In long term plan is interconnections will be built between West Kalimantan and Central Kalimantan. The system will allow shortage in one region to be covered with supply from other regions.

West Kalimantan is left behind in the development of electricity sector. Pontianak is building transmission in a loop system as a kind of interconnection in that city.

PLN in East Kalimantan has a number of major power systems. The largest is the Mahakam system supplying power to Samarinda, Balikpapan, and Tenggarong, the capital of Kutai Kartanegara. The Bontang-Sangatta system supplies power to northern part of East Kalimantan. The Melak and Kota Bangun system supply power for Kutai Barat and Kutai Kartanegara, and the Petung and Tanah Grogot systems for subscribers in southern part of East Kalimantan.

The Mahakam system has 330,000 subscribers using 171.5 MW of power. The PLTGU of Tanjung Batu is one of six power plants in the Mahakam system. Other five plants are diesel fired power plants.

Condition of Power Generating Systems

PLN had a generating capacity of 22,236 MW in Java-Bali in 2007 up from 19,514 MW in 2005. Early 2008, the capacity rose to 22.296 MW with addition of 200 MW from the PLTU of Tarahan in Lampung, PLTP of Darajat and PLTP of Kamojang.

Outside Java-Bali, PLN's generating capacity rose from 5,573 MW in 2005 to 8,284.28 MW in 2007. Among the new plants coming on stream in 2007 were PLTU of Perusda 50 MW and PLTG of Menamas 20 MW. in the Kalimantan systems.

Condition of Transmission Systems

Development of distribution transformer capacity and distribution facilities in the Java-Bali system is shown in the following table.

The transformer capacity of 70/20 KV hardly changed because if growing use of 150 KV transmission system replacing 70-KV transmission cables.

In the past five years, the length of 70 KV transmission cables has continued to be reduced with the upgrading to 150 KV transmission.

Balance in capacity between power plants and transformers in the past five years is shown in the following table.

Improvement in the power distribution system outside Java-Bali system has been significant notably in Sumatra, Kalimantan, and Sulawesi after the completion of a number of transmission systems. Nusa Tenggara, Maluku, and Papua have not transmission system yet.

Construction of main power relay stations grew 11.9% a year with total installed capacity 9,122 MVA in 2003 up to 12,381 MVA in 2006.

3. Growth of electricity sector

Number of subscribers

The number of PLN's subscribers grew slower as a result of the 1998 crisis. Before the crisis the number grew by more than 10% annually, but after that year the annual growth fell to 3%-4%.

The number of subscribers rose from 32.2 million in 2003 to 37.7 million in 2007 or an annual growth of 4%.

Electrification ratio

Household electrification ratio in the country is relatively low--around 60%. The ratio, however, has continued to increased from 56.4% in 2003 to 61.6% in 2007. In Java the ratio was 68.9% and in other regions it was 56.5%.

Sales of Electric Power up 6.4% per year

Sales of electric power by PLN grew 6.4% annually in 2003-007 period. In Java-Bali sales grew 5.9% and in Sumatra by 7.2%.

Coal main fuel

The soaring prices of crude oil force PLN to seek using substitute fuel such as coal, geothermal, gas, etc.

Use of coal by PLN rose in the past five years from 15.2 million tons in 2003 to 31.4 million tons in 2007. However, dependence on oil fuel (BBM) could not yet fully be done away. In 2003, BBM consumption totaled 7.6 million kilo liters, up to 90 million kilo liters in 2006, but down to 5.1 million kilo liters in 2007. The decline in 2007 was thanks to growing use of coal especially by PLN.

Crisis in electric energy

Ideally peak load does not exceed 70% of the capacity to keep a reserve of 30% any time to cope with possible trouble in one of large generators. The condition, however, is far from being ideal in the country. If one of the power plants is out of function or needs repair in Java, blackout is almost certain in some areas.

Although the capacity has continued to increase, the crisis remains a threat. In the Java-Bali system peak load already increased to 16,743 MW as against capacity of 20,000 MW in 2007.

The system is facing a crisis as the peak load if already 83.7% of the generating capacity.

In other regions or islands the installed capacity is 8,284 MW, with generating capacity of 5,029 MW as against peak load of 4,712 MW.

Depreciation of networks and load factor

In the past five years, PLN has succeeded in reducing depreciation of networks resulting in slower rate of network losses. In 2007, network depreciation was only 11.4% and in 2008, the rate is expected to be lower. Annual load factor is 71%-76% in the past five years.

4. Program of primary energy diversification

In the 2006-2015 RUPTL of PLN, 10 units of new power plants will be built in Java and 30 units outside Java-Bali. The 30 units will include 14 units in main program and 16 units to be built as a reserve in case power plants to be built by IPP are not implemented or completed as scheduled. Under the program BBM will account for not more than 5% of electric energy output in 2015.

The government wants diversification of sources of energy and phasing out BBM fired power plants by building more power plants fired with other fuels like coal, gas, etc.

PLN said the increase in the oil price will also cause an increase in the coal price as coal prices are linked to oil prices. Any increase of US$1 in the price of oil a barrel the production cost of PLN will rise Rp600 billion a year.

The coal price paid by PLN follow the trend in the price of Indonesian crude (ICP) of US$ 95 per barrel. Early, July, the ICP averaged US$ 109 per barrel. Therefore, PLN's production cost was estimated at Rp 8.4 trillion in July.

Non-BBM power plants to be built outside Java to be completed in 2009/2010 are shown in the following table.

5. Government subsidy

The electricity tariff set by the government generally is lower than PLN's operating cost and margin. Subsidy, therefore, is needed to keep the company in operation to carry out its PSO (Public Service Obligation). The amount of subsidy needs approval from the House of Representatives.

Subsidy has continued to increase from year to year. In 2005, PLN's subsidy paid by the government reached Rp12.51 trillion, up to Rp17 trillion in 2006, and to Rp32.4 trillion in 2007, up from Rp25.8 trillion set in the state budget before revision.

In 2008, PLN estimated that it will need a subsidy of Rp65 trillion with the soaring price of oil as against Rp55 trillion set in a revised draft state budget for the year.

This year, PLN hopes to be able to save Rp5 trillion through efficiency including Rp800 billion by using MFO instead of industrial diesel HSD, Rp1 trillion through gasification of PLTGU of Muara Tawar, Rp 500 billion through cut in network losses and Rp 2.7 trillion through imposition of non subsidized tariff and distribution of energy saving lamps.

According to PLN's calculation, the target of saving Rp 2.7 trillion from imposition of non subsidized tariff and distribution of energy saving lamps could be achieved of the non subsidy tariff program reaches 33%. Without efficiency PLN is expected to be able only to save only Rp1.4 trillion.

6. Private Power Generating Plants

Before the country was hit by the monetary crisis in 1997, PLN signed Power Purchase Agreement (PPA) and Energy Sales Contract (ESC) with a number of large private companies Independent Power Producer (IPP). After the crisis, PLN and a government team held renegotiations with the IPPs to revise the agreements and contracts especially on prices.

IPPs' plants already operational

In 2006, two large power plants of IPPs PLTU of Cilacap and PLTU of Tanjung Jati B both in Central Java came on line. The two plants helped overcome power shortage in the Java-Bali system.

The coal fired power plant (PLTU) of Cilacap came on line in February 2006 with a capacity of 2 x 300 MW. It was built by PT Sumber Segara Primadaya (S2P) and Chengda Enggineering of China. PT S2P is jointly owned by PT Pembangkit Jawa Bali (PJB) and PT Sumber Energi Sakti Prima. The plant was built at a cost of Rp4 trillion (US$ 510 million) or US$ 850 per kW. The cost is relatively cheap compared to the general price of more than US$1,000 per KW for power generated from coal. Its selling price is also competitive at 4.57 U.S. cents per kWh as against the general price of 4.6 cents to 4.93 cents for coal power.

Construction of the plant took only 24 months. Normally it takes 36 months to build a 300-MW coal fired power plant. The Cilacap coal fired power plant has been used as benchmark for PLN's other projects of coal fired power plants.

The PLTU of Tanjung Jati B was among the projects shelved in the wake of the 1997/1998 crisis. Construction of the project was resumed in July 2003 under President Megawati Soekarnoputri. The coal fired power plant came on stream in October, 2006 with a capacity of 2 X 660 MM. The new power plant serves as a replacement for PLTGU of Tambak Lorok Semarang and other PLTGU using BBM. The operation of the power plant help reduce the use of BBM as much as 1.45 million kiloliters per year or efficiency in fuel of Rp7 trillion a year.

Note :

1) Agreement effective as from the date of signing and the selling price valid for 19 to 30 years after commercial operation.

2) AF = Power suppliers factors to be absorbed by PLN.

3) On 31 December 2000, PLN and Pertamina and Magma Nusantara Ltd. (Wayang Windu project) held interim agreement on the use of price tariff for interim power purchase until the restructured ESC. In 2004, the project was acquired by Star Energy Investment. PLN still is awaiting instruction from the government about negotiation on ESC revision.

4) Formerly it was an IPP project of Himpurna California Energy Ltd. and Patuha Power Ltd. On May 2, 2001, the Indonesian government took over the project by paying US$ 260 million in insurance compensation to OPIC. In 2002, Pertamina and PLN established PT Geo Dipa Energi to resume construction of the project.

Private power generating projects not yet operational are shown in the following table.

7. Development of power plants

PLN has drawn plan for the types of power plant to be developed both in the Java Bali systems and outside Java-Bali

In the Java Bali system the types of power plants to be built include coal--fired power plants with a total capacity of 600MW PLTGU (combined cycle power plants) with a total capacity of 750MW, oil fueled gas power plant (PLTG) with a total capacity of 200MW and hydroelectric power plants (PLTA Pumped Storage unit) with a capacity of 500. See the following table.

8. Projection of power requirement, 2008-2015

The government draws plan for national electric power general plan (RUKN) as an integrated policy in the development of electric power sector covering estimate of electric power provision and requirement, investment policy, source of fund, etc.

Based on the 2006-2015 RUPTL, the country's power requirement will rise from 113.8 TWh in 2006 to 239.5 TWh in 2015 or up 8.5% per year. Peak load is predicted to reach 21,316 MW in 2006 up to 43,694 MW in 2015 or an annual growth of 8.1% per year.

The prediction is based on economic forecasts of the National Development Planning Board (Bappenas) as shown in the following table.

The number of PLN's subscribers is forecast to reach 39.9 million in 2008 up to 57.19 million in 2015 or an annual growth of 6.1% or 2.28 million subscribers. The household electrification ratio is forecast to rise from around 63.3% in 2008 to 77.3% in 2015. The country's population is predicted to rise from 221.6 million in 2006 to 246.8 million in 2015 as shown in the following table.

The target of electrification set by PLN is 76% in 2015 and 93% in 2025.

In 2008-2015, power requirement in the Java-Bali system is projected to rise from 104.2 TWh to 174.4 TWh or an annual growth of 9.6%. Outside Java-Bali the requirement is projected to rise from 29.4 TWh to 65.1 TWh or an annual growth of 17.3 % per year.

Estimates of load requirement are different between RUKN and RUPTL. Based on RUPTL 2008-2016, growth of load requirement will rise from 7.5% in 2008 to 8.7% in 2015. Based on RUKN, growth of load requirement will decline from 7.2% in 2008 to 6.9% in 2016.

9. Conclusion

Although the capacity of generating plants has increased to 22,236MW in 2007 from 19,514 MW in 2005 in the Java-Bali system and from 5,573 MW to 8,282 MW outside Java, the threat of electricity crisis is not yet over.

Currently many areas still have their turn of going through blackouts. Even in Java, the condition is not yet safe.

The government tried to cope with the problem by building more power plants such as through PLN's crash program to build coal-fired power plants with a total capacity of 10,000MW. The crash program is also designed to phase out BBM-fired power plants. The first crash program is scheduled to be completed in 2010. The government plans to launch the second crash program after the completion of the first.

The increase in the price of BBM, which is still used by some of PLNs' power plants will require larger subsidy for electricity as the government has no plan to raise the electricity tariff.

(1) Agreement effective as from the date of signing and the
selling price valid for 19 to 30 years after commercial
operation.

(2) AF = Power suppliers factors to be absorbed by PLN.

(3) On 31 December 2000, PLN and Pertamina and Magma
Nusantara Ltd. (Wayang Windu project) held interim
agreement on the use of price tariff for interim power
purchase until the restructured ESC. In 2004, the
project was acquired by Star Energy Investment. PLN
still is awaiting instruction from the government
about negotiation on ESC revision.

4) Formerly it was an IPP project of Himpurna California
Energy Ltd. and Patuha Power Ltd. On May 2, 2001, the
Indonesian government took over the project by paying
US$ 260 million in insurance compensation to OPIC.
In 2002, Pertamina and PLN established PT Geo Dipa
Energi to resume construction of the project.
