Pangalu Geothermal System is one of the identified geothermal fields in Papua New Guinea in the recently geological reconnaissance studies undertaken by PNG Mineral Resource Authority. It is highly potential reservoir to be commercially exploited for power plant. The preliminary geological studies have demonstrated the possibility of geothermal reservoir not only in Pangalu but other sites in Talasea Local Level Government in Hoskins Electorate of West New Britain Province in Papua New Guinea. In this report, a preliminary environmental impact assessment is presented for Pangalu Geothermal Field. Although ad-hoc basis, PNG Mineral Resource Authority has conducted ongoing studies into Pangalu and other sites in the province for the possibility of using the geothermal energy to produce electricity. A desktop review was carried out of the possible environmental and social effects of this proposed project to model the formulation of environment impact assessment (EIA) in Papua New Guinea. In this review, desktop analysis has been made to identify the possible key impacts of sequence of geothermal phases from exploration to operation, and the potential environment management strategies. It is based on reviews that preparation of Environment Impact Assessment will be modelled in reference to the type of required information to fully disclose the baseline studies and risks that are not catered for so that detailed studies are completely provided in the EIA considering physical, biological, geological, socially, historical and institutional factors in West New Britain Province.
