The survey covered an area of about 50 km˛ centered around the Apas Kiri geothermal manifestations. This survey led to the discovery of sub surface heat water field of 12 km˛ at the northern half of the surveyed area.
Based on this discovery, it is estimated that this area has potential for development of a geothermal power plant with the capacity of 67 MW at a depth of 2.5 km.
Apas Kiri area experienced volcanic activities about 1.5 million years ago, during the Pleistocene age. As such the area is under laid by the Pleistocene formation, predominately covered with sandstone, mudstone, siltstone, shale and lignite.
It is expected that the geological conditions of the area would not pose problems for the development of a geothermal power plant.

Project Overview
The first phase of this 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 single-flash 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. The project is expected to mitigate about 200,000 tonnes of CO² emissions annually.
Discovery of Geothermal Potential in Sabah
Between December 2008 and January 2009, the Minerals & Geoscience Department of Malaysia carried out geoelectric surveys at the Apas Kiri Geothermal Prospect.
