  • TEMPO.CO, JakartaPLN Business Director for western Java region, Haryanto W.S., introduced the diesel-fueled power plants (PLTD) Senayan with a capacity of 101 megawatts as one of the energy reserves sources for MRT Jakarta and the power supply for the capital during an emergency situation.

    “PLTD Senayan will start the operation this October and will readily run as an emergency backup for MRT and a starter power for plants in Muara Karang and Tanjung Priok,” said Haryanto in a written statement in Jakarta, August 8.

    Haryanto explained the operation of MRT Jakarta is supported by two different power sources. So when there is trouble in the main plant, the electricity supply is automatically delivered by the backup source.

    However, if the two plants experience disturbances as occurred on Sunday, August 4, the MRT could still run the operation backed by PLTD Senayan which could last for 8 to 10 hours in a full fuel.

    According to Haryanto, the diesel plant also utilized B20 fuel, a blend of 20 percent of biofuel with diesel, with a ratio of 0.21 liter of fuel per kilowatt-hours (kWh). The amount is more efficient compared to a generator that has an average ratio of 0.3-0.32 liter fuel per kWh.

    Additionally, the noise produced by the generator could be reduced, and the plant is assured to have abode by government regulation.

    As reported earlier, the city’s public transportation such as MRT Jakarta and Commuter Line stopped the operation following the Java blackout on Sunday, August 4. Transportation Minister Budi Karya Sumadi then demanded PLN provide electricity reserves for the national strategic facility.
