A progressive alternative of energy planning for West Sumatera province

Abstract

To ensure energy security for people, the Government develops energy planning, a plan that contains the baseline condition and projected energy consumption and energy supply in specific years. In West Sumatera Province’s Regional Energy Plan (RUED), The Local Government targeted 70.9% renewable energy share in its primary energy mix in 2050. The alternative scenario of power plant generation in West Sumatera base on the Regional Energy Plan Document for 2050 is developed in this paper. The share of renewable energy in the alternative scenario in 2050 is 100%. The alternative energy planning we design meet the expected electricity consumption each year. The Levelized Cost of energy for the alternative scenario cheaper than the RUED scenario in present value. With the rapid development of renewable energy technology, West Sumatera can achieve 100% renewable energy electricity in 2050 and give reasonable energy security confidence.
