In July 2019, PT PLN and the Ministry of Energy and Mineral Resources (EDSM) in Indonesia, signed a collaboration agreement on exploration and drilling of wells in the Mataloko geothermal working area.

The Ministry of Energy and Mineral Resources and PT PLN (Persero) signed a memorandum of understanding (MoU) of exploration studies and drilling of production wells in the Mataloko Geothermal Working Area (WKP).

The MOU was signed by the Head of Geology Agency Rudy Suhendar and PLN’s Strategic Procurement 1 Director Sripeni Inten Cahyani in July 2019.

Head of Research and Development Agency of the Ministry of Energy and Mineral Resources Dadan Kusdiana said the government is committed to increasing the electrification ratio in NTT Province through accelerating electricity infrastructure projects that are sourced from geothermal energy. The signing of the MoU was seen as a form of government commitment.

Flores Island in NTT has 12 regions with geothermal potential, three of which have obtained WKP management permits, namely Ulumbu, Mataloko, and Sokoria with a total installed capacity of 12.5 MW.

With the utilization of geothermal potential, in the future it is expected to significantly increase the electrification ratio in NTT. The Ministry of Energy and Mineral Resources noted the electrification ratio of NTT was among the lowest in Indonesia with 72 percent achievement as of June 2019.

“Along with the development of tourism in the region, electricity demand in NTT continues to increase. Currently, most of NTT’s electricity needs are still being supplied by diesel power plants [PLTD],” he said through an official statement.

In this collaboration, the Ministry of Energy and Mineral Resources through the Public Service Agency (BLU) Center for Research and Development of Electricity Technology, New Energy, Renewable and Energy Conservation (P3TKEBTKE) and BLU Institute for Oil and Gas (Lemigas) will carry out several geothermal studies, including studies risk mitigation, geophysical geochemical geological studies, analysis of environmental impact (EIA) studies, and the use of mobile hydraulic rigs.

Previously, the Lemigas BLU and PLN had worked together to provide consulting services for calculating the actual losses of the Arun Block regasification and procurement of consulting services for the study of gas prices for PLN electricity.

The role of the Geological Agency in this collaboration will be carried out by the Center for Mineral Resources, Coal and Geothermal (PSDMBP) because it has the capability and equipment for geothermal exploration drilling.

Meanwhile, PT PLN Gas and Geothermal (PT PLN GG) as a subsidiary of PLN that handles gas infrastructure and the supply of geothermal electricity, was assigned to develop the Watal Mataloko in the construction of a 2.5 MW PLTP.
