Bali: Launching a rooftop photovoltaic promotion plan, public buildings will be required to install photovoltaic systems.

       To promote local energy use and achieve energy autonomy, Bali, Indonesia, has officially launched a rooftop photovoltaic project, aiming to accelerate the deployment of distributed solar systems in government agencies, public facilities, and commercial premises. 
      Recently, the governor of Bali Province, I Wayan Koster, officially launched the "Socialization Initiative for Accelerating the Implementation of Rooftop Photovoltaic Power Stations in Bali Province". He stated: "All provincial, municipal and county government agencies must use rooftop photovoltaic systems. In addition, all hotels, villas, schools, universities and markets must also install them." 
      This plan is a key component of Bali Province's "Net Zero Emissions by 2045" goal, which was jointly initiated by the Bali Provincial Government and the Indonesian energy policy think tank, the Institute for Essential Services Reform (IESR), in July 2023. 
      According to the IESR assessment, the total photovoltaic power generation potential of Bali is as high as 22 GW, with the potential for rooftop photovoltaic development ranging from 3.3 to 10.9 GW. However, the current utilization rate is still less than 1%. The IESR calls for Bali to prioritize the deployment of rooftop photovoltaic systems equipped with battery energy storage systems (BESS), which is currently the fastest and lowest-cost way to enhance the island's energy supply and ensure energy security, while reducing reliance on power transmission lines from Java. Currently, about 25% to 30% of Bali's electricity is dependent on power transmission from Java through submarine cables. 
      Fabby Tumiwa, the executive director of IESR, pointed out: "The combination of rooftop photovoltaic and energy storage systems can not only meet the surging power demand after the epidemic but also alleviate the pressure on the national power company to increase power supply." 
      According to Indonesia's national energy development goals, by 2040, the country will add 100 GW of new power generation capacity, with 75 GW coming from renewable energy sources, and solar photovoltaic will contribute 27 GW.
