An Update on The Basic Design of Lumut Balai Geothermal Power Plant, Indonesia

Abstract

Lumut Balai Geothermal Power Plant Project is a part of Power Plant Accelerated Development using Renewable Energy as per Ministry of Energy and Mineral Resources (MEMR) Regulation No. 01 of 2012. This policy was taken by Government of Indonesia to increase the energy utilization based on new and renewable energy. Due to the increasing of the electricity demand, Lumut Balai Geothermal Power Plant is expected to strengthen energy supply in Sumatra Island electricity grid system. This technical paper will update the basic design of the geothermal power plant according to previous research published under United Nations University Geothermal Training Programme (UNU GTP) in 2010. The update is indispensable since the project has been progressing. The update is including re-calculation on the heat and mass balance and determination of the main equipments technical specification. The UNFCCC Clean Development Mechanism Project Design Document is also taken into consideration during engineering design phase especially for the monitoring and equipment installation aspect.
