Indonesia Power juga telah melakukan pengukuran dan Indonesia Power measures and calculates wastewater disposal
perhitungan pembuangan air limbah dengan melakukan by monitoring the flow meter, which is recorded daily and
pemantauan flow meter yang dicatat harian serta bulanan monthly, in the Logbook of wastewater disposal from all points of
dalam Log book pembuangan air limbah terhadap seluruh wastewater disposal. In 2021, Indonesia Power's total wastewater
titik pembuangan air limbah. Selama tahun 2021, total volume was 3,504,662.09 megaliters, increased by 22.43% compared to
air limbah Indonesia Power sebanyak 3.504.662,09 megaliter, 2020, which was 2,862,495.46 megaliters. This increase occurred
meningkat 22,43% dibandingkan tahun 2020 yaitu sebanyak because there was an increase in operations of SPP Lontar and
2.862.495,46 megaliter. Peningkatan ini terjadi karena terdapat CCPP Priok units, in which the electricity generation at the CCPP
peningkatan operasional di Unit PLTU Lontar dan PLTGU Priok, Priok increased by 84%, thereby increasing the overall volume of
dimana peningkatan produksi listrik PLTGU Priok mencapai 84% wastewater in these units. [GRI 303-4]
sehingga meningkatkan volume secara keseluruhan volume air
limbah di unit tersebut. [GRI 303-4]
