In December 2007, Wärtsilä got its first order for a Wärtsilä GasCube power plant. PT PLN (Persero) Wilayah Kalimantan Timur, a regional subsidiary of the Indonesian state-owned utility company PT Perusahaan Listrik Negara (PLN) (Persero), ordered two GasCubes for a single site in Bontang in the province of East Kalimantan.

Both plants incorporate a Wärtsilä 16V34SG gas engine rated at 7 MW (Figure 1). The two GasCubes are due to be handed over in March 2009. They will run on locally available natural gas to generate electricity for the national grid. The GasCubes were selected because of their high generating efficiency and small footprint

The Wärtsilä GasCube is a standardized power plant that provides industrial customers, utilities, and independent power producers with economical, reliable, and quickly installed capacity of 7 to 26 MW on a turnkey basis.

Each GasCube is a complete single-engine power plant with all the ancillaries and components needed to form a working power production unit. Each plant is of cubical construction with radiators on the roof and an exhaust gas stack close to the Cube. The GasCube is based on Wärtsilä 34SG engines and can provide up to 9 MW. All components and structures are above ground.

The exhaust silencer and stack are integrated, thereby reducing the plant’s footprint. The small footprint and minimum interface with the surrounding environment open up new possibilities for placing the GasCubes. A closed-circuit cooling system that reduces water consumption to a minimum makes the plant perfectly suitable for remote locations or any location where water is scarce.
