Enviro News Asia, Jakarta — Indonesia has strengthened governance of rooftop solar power through the development and deployment of a national digital monitoring and reporting system aimed at improving data accuracy, transparency, and policy coordination.
The Ministry of Energy and Mineral Resources (MEMR), through the Directorate General of New, Renewable Energy, and Energy Conservation (EBTKE), developed the Rooftop Solar Power Plant Monitoring and Reporting Information System (SIMANTAPS) to centralize registration, verification, and monitoring of rooftop solar installations across the country.
The initiative responds to long-standing challenges in tracking rooftop solar adoption, as data collection previously relied on manual submissions, fragmented reporting, and disconnected verification processes involving regional offices and the State Electricity Company (PLN). These limitations constrained policy planning and weakened confidence in national rooftop solar statistics.
MEMR mandated the establishment of a unified digital system through Ministerial Regulation No. 2 of 2024, which requires integrated registration and monitoring of rooftop solar systems. The regulation aims to support evidence-based policymaking and ensure reliable oversight of solar deployment.
The development and enhancement of SIMANTAPS were supported by the Renewable Energy – Accelerated Transition (RE-ACT) programme, implemented by the Global Green Growth Institute (GGGI) with funding from the Government of New Zealand. The programme provided technical assistance to align the system with MEMR’s data standards, cybersecurity requirements, and inter-agency coordination needs.
SIMANTAPS integrates data from solar applicants, PLN, and MEMR through shared digital interfaces, enabling automated verification and real-time monitoring. The system allows authorities to track installation capacity, geographic distribution, and quota utilization at the national and regional levels.
In March 2025, SIMANTAPS successfully completed User Acceptance Testing and Vulnerability Assessment, confirming its technical readiness and compliance with government information technology standards. The system has since reduced processing times for rooftop solar applications and improved coordination between policy planners and grid operators.
MEMR officials stated that the availability of reliable, real-time data has strengthened institutional decision-making and improved dialogue with PLN and other stakeholders regarding rooftop solar quotas, grid integration, and incentive policies.
The government views SIMANTAPS as a key instrument for advancing digital governance in the energy sector and supporting Indonesia’s broader renewable energy transition through transparent and accountable data management. (*)
