Jakarta – The surge in industrial interest in solar energy utilisation has prompted the Ministry of Energy and Mineral Resources (MEMR) to evaluate and open up opportunities to increase the quota for rooftop solar power plants (PLTS) in 2025.
The Ministry’s Director of Various New and Renewable Energy, Andriah Feby Misna, said in an official statement on Tuesday, 29 April, that the increased interest has led to a longer queue of requests for rooftop solar power plant installations. “We asked to increase the quota because there is a long queue that wants the installed capacity of rooftop solar power plants,” said Feby.
The Ministry of Energy and Mineral Resources noted that as of March 2025, the installed capacity of Rooftop Solar PV had reached 406.78 Megawatts (MW) with a total of 10,437 customers. This achievement reflects a significant increase in the use of renewable energy, especially in the industrial sector, which wants to reduce operational costs and support the clean energy transition.
According to Feby, Rooftop Solar PV is the most strategic solution to encourage solar energy’s rapid and efficient utilisation, especially since its use is more geared towards self-consumption, rather than export to the PLN grid.
“Rooftop PV is most suitable for accelerating the utilisation of solar energy. Unlike large-scale solar power plants, this system is more focused on self-use,” he explained.
The government targets the installed capacity of rooftop solar power plants to reach 1.9 Gigawatts (GW) by 2030. To pursue this target, the Ministry of Energy and Mineral Resources has set a quota for developing Rooftop Solar PV through Decree of the Director General of Electricity No. 279.K/TL.03/DJL.2/2024.
The quota is based on a cluster system and covers Java-Madura-Bali (Jamali) 1,400 MW, Sumatra 80 MW, Kalimantan 89 MW, Sulawesi 17 MW, Maluku, Papua, and Nusa Tenggara 7 MW.
The quota is still dynamic and can be revised according to developments in the field. The annual quota is also arranged in stages, namely 901 MW (in 2024), 1,004 MW (in 2025), 1,065 MW (in 2026), 1,183 MW (in 2027), and 1,593 MW (in 2028).
On the other hand, industry players welcomed the plan to increase the quota. I Made Aditya Suryawidya, Secretary General of the Indonesian Solar Energy Association (AESI), believes that the surge in demand for rooftop solar power plants comes from industries that want to reduce their dependence on PLN electricity.
“The increase from the consumer side is evident, especially from factories that want to install rooftop solar panels. This indicates that both demand and supply continue to grow,” Made said. (Hartatik)
