Ahead of the G20 Summit, PLN President Director Darmawan Prasodjo directly led the electrical security of the G20 Summit from the Nusa Dua Alert Post, Bali. Darmawan said PLN had made thorough preparations to ensure reliability of supply from generating capacity to electricity transmission to the G20 Summit venue on November 15-16, 2022.

"In this case, we are making thorough preparations. We have calculated the supply of balance, between electricity supply and electricity needs it is very well maintained," said Darmawan.

Darmawan revealed that the reliability system of PLN's power plants to support the G20 Summit in Bali reached 1,422 megawatts (MW). The supply comes from a power plant in Bali of 952 MW, transfer of electricity from power plants in Java via underwater transmission or High Voltage Sea Cable Channel (SKLT) of 370 MW and relocation of Grati Gas Power Plant (PLTG) by 100 MW.

Meanwhile, the peak load at the time of the G20 event is estimated to be only 980 MW. This means that there is a power reserve of 442 MW.

"The peak burden that we estimate is 980 MW, today only around 880 MW. So it is far below the estimate we estimate," he added.

To strengthen reliability, PLN prepared supporting equipment such as 102 units of uninterruptible power supply (UPS), 36 units of mobile substations (UGB), 29 units of mobile cables and 68 units of generators.

"We prepared 4 layers of electricity supply. The first is UPS, then there are 4 layers of auctioners from 4 different substations which if there is a direct problem with automatic cascading. Then add a generator. So the reliability is very high," he explained.

To maintain the reliability of electricity supply in this international event, PLN deployed 1,079 officers which were divided into four groups, namely the generation, transmission, distribution, and PT PLN ICON Plus.

"Officers who were deployed to secure the G20 came from Bali and BKO personnel from the main distribution unit and other units from outside Bali," he said.

The PLN officers were not only alerted at the G20 Summit venue, but all electrical joints that supported the electricity supply to the location. To avoid unwanted things, PLN has also mitigated a number of potential risks of interference and sabotage that will be monitored using a number of security parameters.

"To detect unplanned disturbances, PLN has simulated electrical security in strategic locations," said Darmawan.

In addition, Darmawan also ensured that the infrastructure of the Public Electric Vehicle Charging Station (SPKLU) was ready to be used to serve hundreds of electric vehicles during the G20 Summit.

PLN prepared 66 SPKLUs to serve 636 cars. Spread in several locations include ITDC 1 and 2, as well as in Apurva Kempinski. In addition, there are 200 home charging that are ready to serve electric vehicles," he explained.

To ensure the suitability of the inlet (charging port) of each vehicle on the SPKLU, with nozzle or connector, PLN together with other partners provide several types of Ultra Fast Charging SPKLU which will be served directly by PLN officers.

"We have 150 24-hour standby personnel at the location to help recharge electric vehicle batteries," Darmawan explained.

He also said that this SPKLU was integrated with the PLN Mobile application which could monitor all performances from each SPKLU.

Furthermore, to ensure the reliability of electricity, PLN monitors from upstream to downstream. PLN makes electricity monitoring systems from generators, transmissions, event locations to SPKLU.

Then, to ensure the smooth running of the event, the Presidential Security Forces (Paspampres) will also conduct the final SPKLU trial.
