Federal Territory of Labuan are operated and managed by the Sabah Electricity Sdn. Bhd. (SESB). Sabah electrics are mostly generated from diesel power plant, hydropower and combined cycle power plants. The only main hydroelectric plant is the Tenom Pangi Dam. The combined cycle power plant called Kimanis Power Plant was completed in 2014, supplying 300 MW, with 285 MW nominal capacity. The plant is a joint venture between Petronas and NRG Consortium that also includes facilities such as gas pipeline of Sabah–Sarawak Gas Pipeline and a terminal of Sabah Oil and Gas Terminal. There is another two combined cycle power plants with a capacity of 380 MW operated by Ranhill Holdings Berhad. In 2009, the electricity coverage covers 67% of the state population and by 2011 increase to 80%. The coverage reach 100% in 2012 after an allocation of RM962.5 million from the federal government were given to expand the coverage under the 2012 National Budget. The electrical grid is divided into two of West Coast and East Coast which has been integrated since 2007. The West Coast Grid supplies electricity to Kota Kinabalu, Papar, Beaufort, Keningau, Kota Belud, Kota Marudu, Kudat and Labuan with a capacity of 488.4 MW and maximum demand of 396.5 MW. While the East Coast Grid supplies electricity to the major towns of Sandakan, Kinabatangan, Lahad Datu, Kunak, Semporna and Tawau with a capacity of 333.02 MW and maximum demand of 203.3 MW. In 2018, the federal government has announced that Sabah electrical grid will be upgraded to reduce power interruption. Neighbouring Sarawak has also previously announced intention to provide additional electricity power to Sabah with full export will be finalised in 2021. Electricity interconnection between Sabah, the Indonesian province of North Kalimantan and the Philippine province of Palawan as well for the whole Mindanao islands are also in the process as part of the BIMP-EAGA and Borneo-Mindanao power interconnection under the Association of Southeast Asian Nations (ASEAN) Power Grid; with the interconnection with Palawan is expected to be commenced in the nearest future. Since 2007, there is an attempt to establish a coal power plant in Lahad Datu which receiving opposition from local residents and non-governmental organisations for the pollution that would be caused by the plant. Thus Sabah has start to exploring alternative ways to generate electricity with the usage of renewable energy such as solar, mini hydro, biomass, geothermal and micro-algae and
