Mitsubishi Hitachi Power Systems (MHPS), together with Mitsubishi and PT. Wijaya Karya (Persero) Tbk. (WIKA), has secured a contract for a 500MW expansion of the Muara Karang natural-gas-fired gas turbine combined cycle (GTCC) power plant in Indonesia.

The Muara Karang is a natural gas fired turbine combine cycle power plant and it is expected to begin operations in 2019 and the agreement also includes long term service agreement.

Muara Karang project is part for Indonesian government’s 35GW power expansion program under way, which is poised to meet the island country’s increasing demand for electricity fuelled by economic growth.

The project site is located about 10km northeast of Jakart, the country’s capital.

The order from Indonesia's state-owned electricity company, PT. PLN (Persero), will see MHPS supply the main equipment which includes the M701F gas turbine, steam turbine and auxiliaries for the GTCC plant. Mitsubishi will supply and install the generator required for the project.

The civil construction work around the project will be taken care of by WIKA.

Apart from supplying the main equipment, MHPS will also offer maintenance and management of the project including remote monitoring assistance and assignment site service, as per the long term service agreement.

PLN said: "The order has again shown MHPS continuing good reputation in supplying their gas turbine technology to PLN for the past decades and has been providing power to the most important national grid of Jawa-Bali system."

In the past, MHPS has supplied two M701F gas turbines for Cilegon in 2006 and it was the first time that Indonesia used an F-type gas turbine.

This was followed by two M701F gas turbines for the Muara Karang plant in 2011 and another two turbines for the Tanjung Priok Power Plant in 2012. The same project received an extension order in 2016, where two more turbines that produce 880MW in total were supplied by MHPS.

MHPS claims that the GTCC plants are highly efficient systems generating power from gas turbines. Additionally, it will also use the heat generated from the high temperature exhaust to run a steam turbine.
