Tanjung Jati B power station is a 2,640 megawatt (MW) coal-fired power station located in Central Java Province, Indonesia. The power station comprises four 660 MW generating units.[2][3] Tanjung Jati Coal Terminal serves the power station.[4]

The current plant was built in two phases, each comprising two 660 MW units. A third phase of two 1,000 MW units is planned. The project owner, PT Central Java Power (owned by Sumitomo) has executed a finance lease agreement with PT PLN as the lessee. When the lease period expires the assets will be transferred to PLN.[5]

Phase I (Units 1 and 2): 2 x 660 MW

The first phase went through long history of development before finally being commissioned in 2006. The website "Power Plants Around the World" describes the story as follows:[6]

" Tanjung Jati-B was proposed by Hopewell Holdings and initially bid as an IPP in June 1994. A PPA with PLN followed in September 1994. The EPC contract was signed in September 1995 and site work started on 15 April 1997. The Asian financial crisis combined with allegations about mismanagement of the PPA terms led to Hopewell withdrawing, leaving the project about one-third complete. Sumitomo renegotiated the development as a leasing scheme and construction resumed in September 2003 with financing from JBIC. The 5-year project suspension led to parts and equipment being stored onsite and at 75 locations worldwide."

Phase II (Units 3 and 4): 2 x 660 MW

Unit 3 was commissioned in November 2011 and Unit 4 was commissioned in January 2012. The units cost $2.1 billion.[2]

Phase III (Units 5 and 6): 2 x 1320 MW

A third phase of two 1000 MW units is described in PLN's long-range plan for 2013-2022. It is referred to as "PLTU Jawa-4 #5 and #6" and is slated for 2019 and 2020. [7][8] More recently, the size has been described as 2 x 1320 MW.[9]

In December 2013, the government of Jepara Regency renewed its push for the two units to be built. Outstanding issues that that point included lining up investors, land acquisition, building a new transmission line, and lining up government support.[10]

As of March 2015, the plant's proponents were holding public hearings as part of the EIA environmental permit application process. Sumitomo hopes to complete the units by 2019.[11]

The projects is a BOT (Build, Operate and Transfer) scheme of 25 years, after which it will be transfered to PT PLN. The total project cost is expected 500 billion yen, mainly funded by project finance.[9]

Public opposition

At a public hearing in Tubanan Village in March 2015, local fishermen spoke out strongly against the proposed plant. They argued that the company had failed to live up to the standards that it had set in the EIA for Units 3 & 4 in 2007. One complaint was that the plant's owners had failed to put a filter on the water intake as promised, with the result that small fish were getting sucked in and killed.[12]

Waste issues

The plant has had problems with waste disposal. Waste was originally being moved out of the plant via truck, but locals complained that the trucks were damaging local roads. The company then started transporting waste by barge, but fishers were worried that leaking waste would impact fish stocks. The company has only a limited amount of space onsite to store waste, and was concerned that the plant would have to shut down.[13]
