Bloomberg Technoz, Jakarta – The government, through the Ministry of Energy and Mineral Resources (ESDM), officially held the groundbreaking ceremony for the construction of the Legok Nangka Waste-to-Energy (PLTSa / PSEL) National Strategic Project (PSN) in Bandung Regency on Wednesday (July 29, 2026).
Deputy Minister of Energy and Mineral Resources Yuliot Tanjung stated that the project's investment value reaches $400 million, or approximately IDR 7.2 trillion, with a total power generation capacity of 40.79 megawatts (MW).
"PSEL Legok Nangka is designed with a generating capacity of 40.79 MW and an investment value of $400 million or around IDR 7.2 trillion," said Yuliot during the waste-to-energy groundbreaking event in Bandung Regency, quoted from the ESDM Ministry's official YouTube channel on Wednesday (July 29, 2026).
This project represents the first Waste-to-Energy (PSEL) initiative utilizing a Public-Private Partnership (PPP / KPBU) scheme alongside PT Jabar Environmental Solutions (PT JES), backed by a Viability Gap Fund (VGF) facility of IDR 1.34 trillion from the Ministry of Finance.
Additionally, funding is structured through a Joint Crediting Mechanism (JCM) scheme worth $46 million and an international investment of €35 million. This investment is also intended to support the local government in upstream waste management and further waste management training.
"By saying bismillahirrahmanirrahim, we officially commence the construction of the Legok Nangka Waste-to-Energy Project," Yuliot stated.
Yuliot expressed his appreciation to the West Java Provincial Government for supporting the accelerated development of the plant, as well as to the Japanese companies investing in the waste-to-energy sector, Sumitomo Corporation and Hitachi Zosen Corporation who have partnered with national firm PT Energia Prima Nusantara.
"Thank you to the West Java Provincial Government for their support, and to the joint venture companies in this project: Sumitomo Corporation, Hitachi Zosen Corporation, KAISU Electric, partnering with our national enterprise, PT Energia Prima Nusantara," he explained.
The Legok Nangka Waste-to-Energy plant is targeted to process approximately 1,853 to 2,131 tons of waste per day, supplied from Bandung City, Cimahi City, Bandung Regency, West Bandung Regency, Sumedang Regency, and Garut Regency.
Meanwhile, expected revenue streams include a tipping fee set at IDR 386,000 per ton of waste. The electricity tariff is set at $0.0692 per kWh for Years 1–2 based on a business-to-business (B2B) agreement with state utility PT PLN, increasing to $0.1144 per kWh for Years 3–20 under Presidential Regulation No. 35 of 2018.
For context, updates on Japan's funding commitment for the Legok Nangka plant emerged during the 9th Asia Zero Emission Community-Expert Group Meeting (AZEC-EGM) on Monday (January 26, 2026).
The meeting focused on continuing efforts to resolve technical and/or business bottlenecks across various projects within the AZEC framework.
Discussions at the 9th AZEC-EGM were divided into two main sessions. The first session addressed the power sector, focusing on the expansion of the Sarulla Geothermal Power Plant (PLTP), Hululais PLTP, the Java–Sumatra power transmission project, and the Legok Nangka Waste-to-Energy plant.
The second session covered the sustainable fuels sector and other industries, detailing green ammonia initiatives in Aceh and Indonesia's proposal regarding a joint study template for Power Purchase Agreements (PPA).
The Legok Nangka project has undergone an extensive process of technical coordination, financing, and sustainable development planning.
During the meeting, Ueno Asako, Deputy Commissioner for International Affairs at Japan's Ministry of Economy, Trade and Industry (METI), expressed hopes that all six priority AZEC projects would demonstrate significant progress in the near future, particularly before the end of Japan's fiscal year in March 2026.
Previously, the government issued Presidential Regulation (Perpres) No. 109/2025 on Urban Waste Management Through Eco-Friendly Waste-to-Energy Technology.
Under this regulation, the government set the electricity tariff that PT Perusahaan Listrik Negara (Persero) / PLN must purchase from private Independent Power Producers (IPPs) at $0.20 per kilowatt-hour (kWh).
This tariff marks a 48.15% increase from the previous maximum price cap of $0.135 per kWh set in earlier regulations.
Furthermore, PLN is required to prioritize power dispatch from waste-to-energy plants into the grid ("must-dispatched") in accordance with the annual contracted energy amounts agreed upon.
