A Sumitomo consortium has won a contract to build two new geothermal power units as part of Indonesia’s drive to develop 4,900MW in the next five years.

The engineering, procurement and construction contract involves two 20MW units at the Lahendong geothermal area for PT Pertamina Geothermal Energy, a geothermal energy subsidiary of Indonesia’s oil, gas, renewable and new energy company PT Pertamina.

The work will be carried out by a consortium of Sumitomo and PT Rekayasa Industri. Sumitomo Corporation has already built other units at Lahendong. The primary equipment – the geothermal steam turbines and the power generators – will be manufactured by Fuji Electric while construction and installation of the units and steam-field above-ground system will be the responsibility of Rekayasa.
