PLN plans battery storage for Indonesia’s 100 GWp solar programme
The state electricity company says pairing solar generation with batteries could help replace diesel power on Indonesia’s islands.
Indonesia’s PT PLN (Persero) has prepared a strategy for President Prabowo Subianto’s 100 GWp solar power programme, with battery storage planned to support electricity supply beyond daylight hours, according to a company director.
Edwin Nugraha Putra, PLN’s director of technology, engineering and sustainability, said the programme would use Battery Energy Storage System (BESS) technology. Batteries would store electricity generated during the day for delivery to the power system over 24 hours, addressing the limits of solar production when sunlight is unavailable.
Speaking at CEO Talks at the Indonesian Pavilion at COP31 in Antalya, Turkey, Edwin said the combination would allow large volumes of solar power to meet electricity demand. He cited the Java system, which currently has capacity of around 35 GW.
Edwin said the programme could also replace diesel generation, which remains in use on around 741 Indonesian islands. He said reducing reliance on fuel could lower electricity costs and strengthen the power system.
