The Mt. Cabalian Geothermal Project of PNOC-EDC is situated in Anahawan and Cabalian towns, Southern Leyte in Visayas. A power plant with 60-100 MWe installed capacity is projected to be commissioned in Cabalian by year 2008. So far, two exploratory wells (SL1D and SL2D) have been drilled in the project. A bottomhole temperature of about 270 0 C was measured in the well.

Other activities in Cabalian by PNOC-EDC include a one and one-half month magnetotelluric (MT) survey in Cabalian in 1997 utilizing Phoenix V-5 MT system. The MT survey was conducted to further characterize the subsurface geometry of Mt. Cabalian and further define the nature of the hydrothermal resource in Southern Leyte.

The MT data interpretations reveal the presence of a prominent high-resistivity feature beneath the main body of Mt. Cabalian. This finding supports the PNOC-EDC geophysical model that defines the existence of a high-density intrusive body that probably feeds the geothermal resource in Southern Leyte.
