PT Sorik Marapi Geothermal Power, a special purpose vehicle formed by the consortium, will develop the project.
Origin Energy and Tata Power will each hold a 47.5% interest in the concession, while PT Supraco Indonesia will hold the remaining interest.
The Sorik Marapi resource will be tested as part of an exploration program over the next 18 months.
