The geothermal energy is sourced from outside the Cebu province and is supplied by the Tongonan Geothermal power plant, in Leyte through submarines cables. Thanks to that, geothermal accounts for 46.40% of power supply. Hydro power for Cebu is sourced from three facilities located in the western side of Cebu Island (0.50MW Mantavupan Hydroelectric Power Plant in Barili, 0.50 MW Basak 1 Hydroelectric Power Plant and 0.750 MW Matutinao Hydroelectric Power Plant in Badian).
