Purchase of Additional Equity Stake in Muara Laboh Geothermal Power Project in Indonesia

Sumitomo Corporation (Head Office: Chiyoda-ku, Tokyo; Representative Director, President and Chief Executive Officer: Masayuki Hyodo) is a joint participant in the Muara Laboh Geothermal Power Project (the "Project") in West Sumatra Province, Indonesia, working with PT. Supreme Energy, an Indonesian private power generation developer, ENGIE, a major European integrated energy company, and INPEX Corporation. Sumitomo Corporation has entered into an agreement to acquire 15% of equity stake in the Project held by ENGIE. In accordance with this agreement, Sumitomo Corporation’s equity stake in the Project company will be 50%. This transaction is expected to close within 2022 subject to the completions of terms and conditions of the agreement. Through this transaction, Sumitomo Corporation will make itself more involved to the Project and contribute to the realization of low-carbon society in Indonesia.

Sumitomo Corporation is one of the pioneers in the development of geothermal power in Indonesia. We have been involved in the Project before the exploration well drilling and contracted a 30-year long-term power selling agreement with PT. PLN, an Indonesian state-owned electric utility in 2012, supplying enough electricity equivalent to the power usage of 420,000 households in Sumatra, Indonesia. Although Indonesia is the world's second largest geothermal country with approximately 28,000 MW in geothermal resources (Note 1), its rate of geothermal resource utilization currently stands at only about 10 percent. The Indonesian government has set a goal of increasing the country’s geothermal power generation capacity from the current 2,400 MW to about 5,800 MW by 2030 and further developments of geothermal power are expected. In order to contribute to the Indonesian government's goal, Sumitomo Corporation will utilize its knowledge accumulated over the years to expand the Project as well as developing new geothermal projects to continue the contribution to Indonesia's energy transition to carbon-free energy.
