TOMOHON, Indonesia -- Indonesian state oil and gas giant Pertamina is aiming to double its geothermal capacity in the coming years with an estimated investment of up to $4 billion including for the adoption of technology that cuts development costs.
Pertamina -- through subsidiary Pertamina Geothermal Energy -- runs geothermal power plants in six Indonesian regions with a total installed capacity of 672 megawatts. Pertamina President Director Nicke Widyawati said the company wants to double that number to around 1.3 gigawatts, and that it is seeking to build binary cycle units at PGE's existing facilities to boost electricity generation at lower cost.
