1. The Island of the Gods and Its Energy Challenge
Bali, Indonesia’s enchanting “Island of the Gods,” has long captivated travelers with its serene nature and rich culture. However, as tourism booms, so does the island’s energy demand. Annual electricity consumption has surged from 3.2 terawatt-hours (TWh) to approximately 5.8 TWh, driven by a rising influx of visitors. Unfortunately, fossil-fuel power plants still dominate Bali’s energy mix, including the 426-megawatt (MW) Celukan Bawang coal-fired plant and gas-fueled facilities1.
2. Nusa Penida: A Renewable Energy Living Lab

With Bali’s net-zero emission goal set for 2045, Nusa Penida emerges as a renewable energy pioneer. The 3.5 MW Suana solar farm on this island exemplifies the shift toward cleaner energy. By integrating floating solar photovoltaic (PV) arrays with an existing hydropower plant, Bali showcases the benefits of decentralization and resilience. Nusa Penida’s transformation into a 100% renewable energy island sets an inspiring precedent for Indonesia’s archipelago2.
3. The Java-Bali Power System: Scaling Up Renewables

Indonesia aims to achieve 23% of its power generation from renewables by 2025. The Cirata floating PV project, a 145 MW installation on the Cirata Reservoir, exemplifies this commitment. The Java-Bali grid, ready to integrate Cirata, demonstrates minimal impact on power system operations. As more floating PV projects emerge, Indonesia’s energy transition gains momentum, fostering economic growth while preserving its natural beauty2.
4. Community-Led Initiatives: Subak Systems and Rooftop Solar

Bali’s traditional Subak irrigation systems embrace renewable energy. In Keliki Village, Pertamina’s Desa Energi Berdikari leverages solar power. Additionally, PT PLN (Persero) Bali installs rooftop solar power plants across 35 office buildings, totaling 489.72 kilowatt peak (kWp). These community-led efforts empower local economies, reduce carbon footprints, and enhance Bali’s allure34.
Conclusion: Wealth from Clean Energy
Clean energy isn’t just about reducing emissions; it’s an economic catalyst. Bali’s transition to renewables creates jobs, attracts sustainable investments, and ensures a vibrant future. As the sun kisses Nusa Penida’s solar panels and the waves dance around floating PV arrays, Bali exemplifies how wealth and nature can harmonize. Let’s celebrate this paradise’s journey toward a greener horizon1.
Bali’s energy transformation is a beacon of hope—a testament to how clean energy can enrich lives while safeguarding our planet’s treasures. 🌿🌞🏝️
