PLN, the state-owned electricity company, has successfully operated a remarkable fleet of 266 hydroelectric power plants (PLTA) and micro-hydro power plants (PLTMH), boasting a combined capacity of 18.9 gigawatts (GW). With a clear vision to reduce reliance on fossil fuels, PLN is diligently working towards enhancing its electricity capacity derived from renewable energy sources.
Darmawan Prasodjo, the President Director of PLN, expressed their commitment to advancing hydro-based power technologies, thereby mitigating dependence on fossil energy.
In his words, “PLN is resolutely committed to developing hydro-based power technologies to decrease our dependency on fossil energy sources,” as stated in a recent press release (9/7/2023).
Significantly, PLN’s water consumption has reached a substantial figure of 24 million metric tons during the course of 2022. This water is primarily utilized for operational purposes in power generation and for domestic needs. Ensuring sustainability in water usage is of utmost importance to PLN, who has taken measures to enhance water efficiency and reduce the consumption of raw water.
Darmawan noted, “We prioritize sustainability aspects in our water usage and have implemented efficiency measures to reduce the volume of raw water consumed.”
One notable approach employed by PLN is the implementation of a closed-cycle system, enabling the reuse of water and minimizing waste. This methodology aligns with the principles of the 3R concept: reduce, reuse, and recycle. By adhering to these principles, PLN aims to optimize water utilization and contribute to overall efficiency.
Darmawan emphasized that this water efficiency program extends beyond PLN’s operations, involving stakeholders such as community groups to participate in alternative water sourcing initiatives.
He explained, “This water efficiency program not only benefits PLN but also the broader community by engaging stakeholders, including community groups, in sourcing water from alternative sources.”
In a significant showcase of their commitment to sustainable water management, PLN recently participated in a workshop side event leading up to The 10th World Water Forum in 2024.
The theme of the event, ‘Water for Shared Prosperity,’ held at Gadjah Mada University (UGM) in Yogyakarta, highlighted PLN’s dedication to responsible and sustainable water utilization practices.
Herry Trisaputra Zuna, the Director General of Infrastructure Financing for Public Works and Housing, emphasized the government’s prioritization of sustainable water management. This prioritization aligns with the overarching principles of environmental, social, and governance (ESG) and the Sustainable Development Goals (SDGs).
Zuna stated, “The government is actively undertaking various measures to enhance sustainable water management, recognizing its pivotal role in addressing climate change and promoting community well-being.”
As PLN continues to spearhead advancements in hydro-based power technologies and actively engages in sustainable water management practices, they are playing a crucial role in driving the energy sector towards a greener and more sustainable future.
