The plants' aggregate capacity totals 255MW.
A consortium between the technology group Wärtsilä and an Indonesian construction company, PT PP (Persero) Tbk, has been contracted to supply five power plants, totalling 255 MW, to PT PLN, the Indonesian state utility.
Wärtsilä statement said that the consortium will be responsible for the complete engineering, procurement & construction (EPC) of the projects, and will also operate and maintain the power plants for a 5-year period.
The five plants are covered by two separate orders. One order comprises four modular gas cube power plants, totalling 115 MW. The gas cubes will be located in Ternate, Nabire, Bontang and Flores. The second order, a 140 MW power plant, will be 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.
The four gas cube power plants are scheduled to be operational in late 2017 and early 2018, and the Bangkanai plant in late 2018. The orders have been booked in the first quarter of 2017.
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. Wärtsilä announced the award of a contract for two similar plant deliveries in December 2016.
The 140 MW Bangkanai phase II power plant will complement an existing Wärtsilä-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.
Wärtsilä will take on the daily operation and maintenance of these five power plants, to optimise the performance and production lifecycle of the installations. The five-year operations & maintenance agreement includes expertise areas such as recruitment, management and training of local personnel, technical support, maintenance planning, performance monitoring and logistics management, as well as preventive and predictive maintenance to meet local health, safety and environmental requirements.
