System (SSIS) and the rest is supplied by isolated system power plants in Bengkalis, Selat
Panjang, Pkl Kerinci, Sungai Guntung, Kuala Enok, Pulau Kijang/Kota Baru,
Seberida, Tembilahan, Rengat, Air Molek, Pasir Pangaraian, Siak S Indrapura, and Bagansiapiapi. In 2011

Energy Potentials
Riau has diversified energy potentials consisting of oil, natural gas, coal,
and thermal. Oil potentials are estimated to reach 3,847.79 MMSTB, natural gas potentials are
estimated to reach 9.01 TSCF, coal potentials are estimated to reach 2,400.94
million tonnes, and thermal potentials are estimated to reach 25 MWe in Pasir Pangaraian. Electricity Demand Estimate
It is projected that demand for electricity in Riau for the period 2012–2031 shall grow by 13.4% per year so that in 2031 electricity need is expected to reach 28.0 TWh. To fulfill estimated peak utilization growth of averagely around 13.0% per year until 2031, then additional power of averagely around 345 MW per year shall be needed.
