Lahendong Geothermal Power Plant, Clean Energy Pilot Project for Indonesia

Peresmian PLTP 10

Energy use is inseparable from human daily needs, such as electricity. Nowadays most electricity needs are still supported by the use of fossil fuels that can be used up someday. This is the reason for the Jokowi-JK Government to encourage the use of renewable energy, one of which is the use of geothermal energy. The German Earth Sciences Research Center Geo Forschungs Zentrum (GFZ) handed over the Lahendong Geothermal Power Plant (PLTP) with a capacity of 500 kW to the Agency for the Assessment and Application of Technology (BPPT).

"We, on behalf of the government, appreciate the highest level of cooperation with Germany in order to continue," said Minister of Research, Technology and Higher Education Mohamad Nasir in between handover assets of 500 kW PLTP Binary Power Plant in Lahendong Geothermal Field, Tomohon City on Monday (January 21).

The handover of the assets is part of a series of agreements between Menristekdikti (the Indonesian Ministry of Research, Technology and Higher Education) and the German Federal Ministry of Education and Research (BMBF) signed in April 2010 in Denpasar, Bali; and the agreement to implement sustainable development of geothermal energy in Indonesia between GFZ and BPPT signed in June 2010.

Menristekdikti said the government was committed to increasing the use of renewable energy to reach 23% by 2025. Until this year the portion of renewable energy use in Indonesia was only around 8% to 9%. "The geothermal itself only contributes 4% of 9% renewable energy. So the potential is still very high," he said .

Acting Head of BPPT Wimpie Agoeng N. Aspar said that after the transfer of assets from Germany to BPPT, the Lahendong 500 kW PLTP (geothermal power plant) will be operated by PT Pertamina Geothermal Energy (PGE).  "We and PGE are currently running a 500 kW PLTP in Lahendong. This tool is a grant from Germany. We want this tool to be useful as a potential clean energy-based plant to be a model that can be applied in areas with potential geothermal sources in Indonesia," said acting head of BPPT. He said the operation of geothermal power plants is in line with the government's commitment to reduce the impact of climate change and global warming. Wimpie also explained that the Lahendong PLTP was the first power plant to use a binary cycle system in Indonesia. Lahendong PLTP can also be used as a model for the utilization of geothermal wells with wet steam which is characteristic of most geothermal sources in Indonesia, especially in the Sumatra and Sulawesi regions. He explained that BPPT and GFZ and PGE had successfully operated the Lahendong PLTP 500 kW continuously for more than 10 months in 2018.

"This signifies BPPT's initial readiness with domestic operators and industries to build geothermal power plants throughout the archipelago that have geothermal energy sources. We hope that the handover of PLTP Binary Cycle can be the first step for big efforts to utilize geothermal energy," he said. Along with this event four cooperation agreements were also signed, namely

Peresmian PLTP 7(a) The signing of the cooperation on the Assessment and Application and Correctional Technology to support Human Resource Development and Community Service between BPPT and Samratulangi University,

(b) The signing of the cooperation on Optimization of Performance of the 500 Kilowatt Binary Cycle Geothermal Power Technology Technology in the Tomendong Lahendong Geothermal Field, North Sulawesi Province between the BPPT's National Laboratory for Energy Conversion Technolgy (B2TKE-BPPT) and Manado State Polytechnic,

(c) Joint Study Agreement on the Assessment and Application of 500 Kilowatt Binary Cycle Geothermal Power Generation Technology in the Lahendong Geothermal Concession Region, North Sulawesi, between the B2TKE-BPPT and PT Pertamina Geothermal Energy,

(d) The signing of the cooperation on the Assessment and Application of Power Plant Technology to Improve Human Resource Capability, between BPPT and Manado State Polytechnic.

Bara Hasibuan, member of the House of Representatives Commission VII also said that this moment was history for Indonesia. He was very proud to be a witness in the handover of this project. Bara also said that North Sulawesi is 1/3 of the geothermal resources in Indonesia besides Sumatra and others.

"I hope that by 2025, Indonesia can streamline energy use by using renewable energy. This project is very beneficial for the outer islands or regions in Indonesia. I am also committed, as a representative of the House, to always support technological developments like this, as North Sulawesi it is very rich in geothermal resources, and hopes that this geothermal energy will become the main energy resource in the future", he said.

On this occasion, the Governor of North Sulawesi also expressed his gratitude to GFZ and PGE for being able to have geothermal power plants, where up to 120 MW of geothermal power has been used from this geothermal research.

The German Ambassador, Peter Scoof, also revealed that this collaboration was the commitment of the German Government to reduce the impact of climate change through the geothermal utilization delivered today. In Indonesia there are 2.5 GigaWatt of geothermal potential that can be utilized and the German government has contributed in total with the best researchers in Indonesia in geothermal development, to reduce emissions related to reducing the impact of global climate change. "We hope that in the future this prototype can be duplicated and multiplier effects throughout Indonesia," Schoof said.

The handover activity was also attended by the Governor of North Sulawesi and Mayor of Tomohon, who also delivered remarks, as well as representatives from Kemenristekdikti (Jumain Appe Director General of Innovation Strengthening and Hotmatua Daulay), Pertamina Geothermal Energi (PGE), Manado Local Government, Commission VII DPR, GFZ (Geo Forschungs Zentrum / German Research Center for Geosciences), BMBF and German Embassy in Indonesia, PLN, ESDM, Samratulangi University, Manado University, and Manado State Polytechnic.
