Operating 67 power plants, PLN uses 24 million metric tonnes of water

Yogyakarta – President Director of PT PLN (Persero), Darmawan Prasodjo said that the potential of abundant water resources is an important opportunity in PLN’s business process. He said PLN continues to innovate in energy transition, one of which is by developing hydrogen technology to generate electricity.

In realisation, PLN has operated 67 hydropower plants (PLTA) and 348 micro-hydro power plants (PLTMH), with a total capacity of 5,651 megawatts (MW). This was conveyed at a series of side event workshops towards The 10th World Water Forum in 2024 with the theme “Water for Shared Prosperity” held at Gadjah Mada University (UGM) Yogyakarta.

“PLN utilises water to produce clean electricity and can electrify millions of people throughout Indonesia,” Darmawan said in a written statement.

According to Prasodjo, PLN is determined to continue developing hydrogen-based electricity technology to reduce dependence on fossil energy while achieving the Net Zero Emission target by 2060. He said, as a state-owned enterprise that utilises water for its business processes, PLN has prioritised sustainable governance.

Throughout 2022, PLN’s total water consumption will reach 24 million metric tonnes. Prasodjo said that they prioritise the sustainability of water use, the majority of which is consumed for operational activities, both generation and domestic.

He gave an example where in power plant operations, PLN uses water with a closed cycle or reuse system to minimise waste and prioritises the 3R (Reduce, Reuse, Recycle) principle in water utilisation to support efficiency. This way, they were able to reduce water usage for both generation operations and supporting activities by 23.12 million metric tonnes from 33 plants in PLN, said Prasodjo. (Hartatik)
