Paiton Power Station


Paiton Power Station is a large thermal power station located around 35 km to the east of the town of Probolinggo in East Java in Indonesia, about half way between Probolinggo and Situbondo. The extensive complex has a maximum generating capacity of 4,710 megawatts. It is the largest power station in Indonesia and the 10th largest coal-fired power station in the world.

History of the plant

The history of the construction of the power complex, along with the financial arrangements, involved considerable controversy in the wake of the 1997-98 financial crisis in Indonesia.
The firm decision to begin construction of the complex was taken in April 1994 after negotiations which had commenced some years earlier. The construction of the Paiton complex was seen as important because it was part of an ambitious program announced in the mid 1990s in Indonesia to construct 27 power plants in cooperation with the private sector through IPP arrangements. But following the 1997-98 financial crisis in Indonesia, the IPP arrangements were widely regarded in Indonesia as inappropriate contracts which, as a result of faulty contract negotiations, had passed an excessive allocation of financial risk onto the Indonesian state.
According to the original contract signed between the Indonesian state-owned electric power company Perusahaan Listrik Negara and PT Paiton, PLN was to pay PT Paiton a price of slightly over US 8 cents/kWh during the first 12 years of operation of the plant. However, following the dramatic plunge in the value of the rupiah during the 1997-98 crisis, PLN's financial situation deteriorated sharply. In 1999, the PLN therefore moved to demand that the contract be renegotiated. After difficult negotiations, agreement was reached in mid-2002 for the PLN to pay PT Paiton a reduced price of slightly less than US 5 cents/kWh for part of the output from the Paiton complex.
More recently, the capacity of the plants at the site was extended. In 2004 it was announced by one of the firms operating at the complex, PT Paiton Energy, that an additional 800 MW would be added to the 1,290 MW capacity that the firm operated at the site. In 2007, PLN started construction of Paiton Unit 9 in cooperation with Harbin Power Engineering Company Limited. Unit 9 power plant, owned by PT PLN, is a sub-critical plant. In mid 2012, PT Paiton Energy launched the commercial operation of the unit adding around 5% to the capacity of the Java-Bali power grid.

Ownership arrangements

The Paiton power generation complex is made up of a number of power generation units under different ownership. Details are as follows:
Capacity Ownership
Units 1 & 22 x 400 = 800PT Pembangkitan Jawa Bali
Units 3800 PT Paiton Energy
Units 5 & 62 x 610 = 1,220PT Jawa Power
Units 7 & 82 x 615 = 1,230PT Paiton Energy
Unit 91 x 660 = 660PT PLN
Total4,710 MW

= The area for planned Units 3 & 4 is currently occupied by an 800 MW supercritical power station.

Flue Gas Treatment

Paiton I and II both incorporate saltwater Flue Gas Desulphurisation scrubbers.
