Renewable Energy Potential Mapping of Industrial Area in Central Java

The industrial sector is one of the economic pillars providing the largest portion of Indonesia's national Gross Domestic Product. The sector is affected by the government planning to reduce greenhouse gas emissions (GHG) through Eco-Industrial Park Program. An example of the program is implementing renewable energy (RE) to support the business process, such as providing electricity needs. The national electricity company (PT.PLN) currently provides electricity in the industrial area. This research analyzes the demand and supply of electricity in the industrial area to support government programs. Central Java is chosen as a case study because it has an enormous capacity for industrial areas compared to the other province in Indonesia, and the local government commits to promoting renewable energy. The results show that seven industrial areas in Central Java Province require 1,274.7 MW of electricity. Furthermore, the renewable energy potential is analyzed within a radius of 25 km from the industrial area. The resources that analyze are solar, wind, biomass, and hydro. For example, the total energy potential in Sugihmanik areas for solar, wind biomass, and hydro is 5.13, 0.1, 2.54, and 21.58 MW, respectively. Based on the analysis, it is known that each industrial area can provide electricity demand by utilizing renewable energy potential around their area.
