Promoted with Pride

Promoted with Pride

Tangguh, the name of the project, means "strong" or "tough" in Indonesian language. LNG production commenced in the midst of the decline in LNG production in Indonesia, while the government and people of Indonesia had high hopes that the new project would contribute to the country's economic development and future stability.

Sale of LNG to New Markets

LNG Sales to New Markets with Expected Demand Increase

The LNG to be produced by the Tangguh project will be shipped to three destinations: Sempra's LNG terminal in Baja California, Mexico; the LNG terminal being built by CNOOC in Fujian, China; and the Gwangyang LNG terminal in Korea for further delivery to POSCO and K-Power. The sale of LNG to Sempra marks the first time in the world that LNG produced in Asia will be supplied to a terminal on the west coast of North America under a long-term contract.

Tangguh Expansion Project

The final investment decision on the Tangguh Expansion Project was made in July 2016. The Tangguh Expansion Project will add a third LNG process train (Tangguh Train 3) with 3.8 million tons per annum (mtpa) of production capacity to the two trains under operation with 7.6 mtpa of production capacity. The production from the Tangguh Train 3 is expected to commence in 2020.

The Tangguh Expansion Project will play an important role in meeting the growing energy demand in Indonesia by supplying 75% of the LNG increasingly produced by the Tangguh Train 3 to the state electricity company PT. PLN (Persero). The project will also contribute to the energy security in Japan by supplying 25% of the LNG increasingly produced by the Tangguh Train 3 to THE KANSAI ELECTRIC POWER CO., INC.
