HVDC Project will be temporary postponed starting November 2, 2016 at least for 2 (two) years. We are sorry not to reply any email within this time.
Jakarta, November 30, 2016
INDONESIA, a country of about 1,910,000 km2, consists of about 18,000 islands including such main islands as Java, Sumatra, Kalimantan and Bali, etc., with population of about 237.5 million (2011 estimate). Rapid increase of power demand has resulted in as follows:
According to the Long Term Electricity Development Plan (RUPTL 2011-2020, hereinafter referred to as ”RUPTL”), the peak demand in Indonesia nationwide in 2010 was 25,177 MW and it is expected to grow into 55.053 MW (an average of 8.14% per year) by 2020, thus alleviating the stringency in power demand is the urgent issue.
In respect to the government plan to accelerate energy diversification of non-oil fuel power plants and taking into account the large coal deposit in Sumatra, three coal-fired steam power plants under the Independent Power Producer (IPP) scheme are being constructed in Bangko Tengah of South Sumatra, which are called as Mine-Mouth Coal-fired Power Plants. The power plants will have total capacity of 3,000 MW. In order to transfer the electricity from the Mine-Mouth Coal-fired Power Plants, PLN intends to install HVAC transmission line there from and furthermore to install a ± 500 kV bipolar converter station with transfer capacity of 3,000 MW capacity measured at the inverter AC bus bar.
Regarding the limited energy resource and power plant location in Java, the Java-Sumatra HVDC Interconnection System is needed in order to transfer power from Mine-Mouth Coal-fired Power Plants at South Sumatra to the load center in Java. This Project will improve the power supply in Sumatra and Java, to ease the stringency of power demand in both the Sumatra System and the Java System and to improve the reliability of power supply by interconnecting these two systems with the construction of ± 500 kV HVDC overhead transmission line, marine (sub-sea) cable and converter/inverter and switching station. Through this Project the following effects are expected:
