Indonesia to construct 93 Power Plant

2 February 2010 - The Indonesian government has announced its list of 93 power plants to be built under its second 10 000 MW power generation scheme.

Mr J Purwono, director general for electricity and energy use, said: "With the issuance of the decree, the bidding for the power plant procurement can now be opened," according to the Jakarta Post.

The power plants are expected to generate up to 10 153 MW in total. Of this figure, 5770 MW or 57 per cent will go into the Java Bali grid, while the rest will go to the other islands across the archipelago. This second project is expected to promote the use of clean and renewable energy, but coal fired power plants will still contribute significantly.


Of the total capacity, up to 1204 MW will be generated by hydroelectric plants, 1660 MW from gas combined-cycle plants, 3977 MW from geothermal plants and 3312 MW from coal fired plants.

The biggest hydroelectric plant in the project will be the 4 x 250 MW Upper Cisokan plant in West Java. The biggest combined-cycle plant will be the expanded Muara Tawar plant also in West Java with total capacity of 1200 MW.

The 1000 MW Indramayu power plant in West Java will be the biggest of the coal fired plants in this second phase while the Sarulla 1 plant in North Sumatra with expected total capacity of 3 x 110 MW will be the biggest of the geothermal power plants.

Of the total 10 153 MW power expected to be generated from the project, state electricity company PT PLN is expected to generate a little more than half, or 5118 MW. The remaining 5035 MW is expected to come from plants run by independent power producers.

Constructing all the power plants will require $15.96bn in investment. Of this figure, only $5.9bn will go to PLN. The IPPs will require a greater capital outlay as they will focus on geothermal power plants which are far more costly than PLN coal fired plants.

Of the total 3977 MW set to be generated by geothermal, IPPs are expected to contribute 3097 MW. The second 10 000 MW project will include the construction of 3490 km of power transmission lines, requiring $383m in investment. The project is expected to be finished in 2014.
