Finnish group Wartsila is to supply five power plants in Indonesia.

Wartsila is in a consortium with Indonesian construction company PT PP to deliver the plants, which will have a total capacity of 255 MW.

The plants are being built for Indonesian state utility PT PLN and the consortium will be responsible for the complete engineering, procurement & construction and will also operate and maintain the facilities for five years.

The five plants are covered by two separate orders. One order comprises four modular ‘gas cube’ power plants, totalling 115 MW.

Wartsila’s so-called gas cube is a ready-to-use, pre-engineered, modular power plant package especially designed for fast-track delivery with minimal site work. In addition to the short installation time, it can also be easily dismantled and re-installed in another location if required.

The gas cubes will be located in Ternate, Nabire, Bontang and Flores.

The second order is for a 140 MW power plant located in Bangkanai, in Central Kalimantan on the island of Borneo.

All five power plants include Wärtsilä 34DF engines capable of running on multiple fuels, such as liquid fuels and natural gas.

Wartsila says this “significantly increases the operational flexibility and reliability” of the plants.

The four gas cube power plants are scheduled to be operational later this year and early 2018, and the Bangkanai plant in late 2018.

The four gas cube power plants are part of a public tender announced by PT PLN last year, and they will provide flexible baseload power to the Indonesian grid.

The 140 MW Bangkanai phase II power plant will complement an existing Wartsila-built gas power plant located in the middle of jungle terrain in Bangkanai. The two plants will have a key role in producing electricity for the Kalimantan grid and helping to meet the area’s growing electricity demand. 

“These contracts showcase the strength of our relationship with the state utility, PT PLN,” said says Frederic Carron, Wartsila regional director. “The Bangkanai plant is located in a rather demanding environment and PT PLN knows that we can deliver an EPC on time, even in such tough conditions.”
