Tawau Green Energy (TGE) is currently developing Malaysia's first geothermal power plant project at Apas Kiri, Tawau in the east coast of the state of Sabah in Malaysian Borneo.
The first report on geothermal potential in Tawau was published in 1962 by the British North Borneo Geological Survey. Many reports have been published since then.
Magneto Telluric (MT) survey was commissioned in 2008-2009 by Malaysia's Mineral & Geoscience Department (JMG). This survey, conducted by University of Science (Malaysia) and University of Indonesia, suggested a geothermal energy potential of 67MW in Apas Kiri, Tawau.
Tawau Green Energy undertook a detailed and expanded geothermal exploration program, comprising geology, geophysics and geochemistry surveys, from 2011-2015.
The first phase of the project will include:
Exploratory wells to establish the parameters and potential of the geothermal reservoir;
Production and re-injection wells based on the reservoir management plan;
36MW (gross) power plant utilizing binary technology;
132kV interconnection to SESB's State Grid for export of 30MW.
The electricity generated will be sold to SESB under a 21-year Renewable Energy Power Purchase Agreement.
Geothermal surface manifestations are an indication of active geothermal systems.
