No.2 Unit of Guohua Electric Power’s Coal-fired Power Plant in Java Put into Operation

The No.2 unit of a China Energy-funded coal-fired power generation project that involves two 1050MW units in Java, Indonesia — the largest overseas coal-fired plant built by a Chinese enterprise in terms of the installed capacity with Chinese intellectual property — passed a 168-hour test run smoothly on September 23, marking the completion of the high-efficiency, eco-friendly power plant with the largest unit capacity, the highest parameters, the most sophisticated technologies and the best indicators in Indonesia’s electric power history.

On December 13, 2019, the No.1 unit of the project was put into operation, four months before the end of the PPA contract, and it continued operating safely and stably afterwards. This time, the 168-hour test run of the No.2 unit coincided with the critical stage of the COVID-19 pandemic. The company’s leaders coordinated resources of all participating units and worked out epidemic prevention measures in a scientific and dynamic manner according to the epidemic situation. A total of 202 Chinese employees were organized to resume construction in 20 batches, which effectively promoted steady progress of all debugging works including plant service power consumption, turbine impulse turn, grid-connected electricity generation, RB test and 168-hour full load test operation. The boiler efficiency of the unit was 92.69 percent, the heat consumption of the steam turbine was 7,438.29kJ/kWh, the plant power consumption rate was 4.16 percent, and the coal consumption for power generation was 288.64g/kWh. All these indicators are better than the design values, and major environmental protection indicators are the best in Indonesia.

Java 7 project is located in Banten Province on the island of Java, Indonesia, with a total investment of more than US$1.88 billion and a total installed capacity of 2×1050MW. Upon completion, the project is expected to generate 15 billion kWh of electricity each year, which will effectively improve power supply in Indonesia, greatly alleviate the electricity shortage on Java island, and drive local economic growth and social development.
