Asset divestment update: Origin agrees to sell interest in Indonesian geothermal project

Origin Energy Limited (Origin)[1] today announced it had entered into a Sale Agreement with KS Orka Renewables Pte Ltd for the sale of its 50 per cent interest in OTP Geothermal Pte Ltd (OTP) for a cash consideration of US$30 million.

OTP, a 50:50 joint venture with Tata Power International Pte Ltd, holds a 95 per cent interest in Indonesia’s PT Sorik Marapi Geothermal Power (SMGP). SMGP is currently progressing the development of the 240 MW Sorik Marapi Geothermal Power Project in North Sumatra.

The divestment of Origin’s interest in OTP is consistent with the company’s strategy to reduce debt and narrow its focus to two core businesses, Energy Markets and Integrated Gas.

The sale is subject to customary conditions including approvals from relevant Indonesian government authorities.
