Pertamina’s important role in Indonesia’s geothermal development ambitions
With a current installed geothermal power generation capacity of 672 MW, 1,200 MW under joint operating contracts, Pertamina will continue to be a key player in geothermal development in Indonesia.
Last month we shared an article that discussed the important role of state-owned enterprises for geothermal development in Indonesia.
So while PT Geo Dipa Energi has been very visible and outspoken about its current development activities, the likely most important state-owned player to that day still is oil company PT Pertamina and its subsidiary PT Pertamina Geothermal Energy.
Pertamina continues to boost the use of geothermal energy to encourage a more environmentally friendly energy transition in Indonesia. In the next five years, Pertamina will double the installed capacity of its Geothermal Power Plant (PLTP). PT Pertamina’s Senior Vice President (SVP) Strategy & Investment, Daniel S. Purba, said that currently Pertamina operates around 672 Megawatts (MW) of PLTP installed capacity. In the next five years, that capacity will increase to 1,300 MW or 1.3 Gigawatts (GW). “From the reserve side, we have quite a lot of potential,” said Daniel in a webinar forum, in October.
In developing geothermal energy, Pertamina is supported by its subsidiary, namely Pertamina Geothermal Energy (PGE). PGE’s Corporate Secretary Mindaryoko explained that currently PGE is managing 14 Geothermal Working Areas (WKP) with a total installed capacity of 672 MW. All these areas are operated independently (own operation) by PGE.
A total of 672 MW is spread across PLTP Kamojang in West Java of 235 MW, Lahendong in North Sulawesi (120 MW), Ulubelu in Lampung (220 MW), Sibayak in North Sumatra (12 MW), Karaha in West Java (30 MW) and Lumut Balai in South Sumatra (55 MW).
In addition to the installed capacity which is operated alone, PGE has 1,205 MW which is run under a joint operation contract (JOC). In details, three JOCs with Star Energy in Wayang Windu, Darajat and Mount Salak Fields, as well as one JOC carried out by Sarulla Operation in Sarulla Field, North Sumatra.
“Geothermal potential in Indonesia is still large, so PGE continues to commit to developing geothermal energy as a new and renewable energy,” said Mindaryoko.
