A Scenario of BAPV and BIPV System for Long-term Projection Energy Demand in Yogyakarta

Indonesia has several problems in various fields; one of them is the energy sector. Demand for existing energy and supply was not balanced, which causes the emergence of energy problems in multiple regions especially in areas that have a small electrification ratio. The limitations on fossil energy resources, made our country find another alternative, that is to evolving renewable energy potential for solutions to meet energy demand. Some renewable energy resources that can be evolved in Indonesia are solar energy, hydro energy, wind energy, geothermal energy, and biofuels. This study focused on the use of solar energy systems, namely photovoltaics. Other countries had been developed photovoltaic into a more complex system, that called BAPV (Building Added photovoltaically) and BIPV (Building Integrated Photovoltaic), which means that photovoltaic was embedded in or becomes part of a building either home, office or hotel. The problem that's focused of this research was whether the BAPV and BIPV systems could also be an alternative choice in meeting the electricity needs in Yogyakarta city. Yogyakarta city doesn't have the potential for fossil energy resources, therefore Yogyakarta city was very appropriate to use as an object of renewable energy projections. In the projection of BAPV and BIPV systems as projection scenarios, a platform that used was an application to make a long-term projection, that is LEAP (Long-range Energy Alternative Planning).
