Construction Underway: Ulumbu Geothermal Power Project (2 x 2.5 MW)
Under a contract with PT Perusahaan Listrik Negara (PLN), Geothermal Development Associates (GDA) agreed to design, manufacture, test, and ship two geothermal steam turbine generator sets and related power plant auxiliary components from Reno, Nevada, USA to Surabaya, Indonesia. GDA will also provide supervision and technical support during installation and commissioning of the plant.
PLN personnel traveled to the US to witness factory tests and to attend classroom training at GDA’s Reno offices. GDA will provide additional training to PLN staff during commissioning.
GDA’s modular plant was shipped in containers to the site in late 2013 approximately six months after notice to proceed from PLN. Construction is currently underway at the site, with commissioning expected to begin in June, 2014.
PLN is Indonesia’s state owned electricity company with a total installed electric capacity of 26,895 MW in December 2010, of which 439 MW (2%) were geothermal. PLN currently has 11 geothermal units in operation.
The Ulumbu geothermal field is located 11 km to the south of Ruteng, the capital of Western Flores, in the Kabupaten (Regency) Manggarai, Flores Island, in the East Nusa Tenggara Province of Indonesia.
