Sembcorp has launched a 50MW solar project with a 14.2MWh battery storage system in Nusantara, Indonesia’s future capital. This is Sembcorp’s first large-scale solar venture in Indonesia, developed in partnership with PT PLN Nusantara Renewables.
Solar Project to Features 114,420 Bifacial PV Modules
PT Sembcorp Renewables Indonesia partnered with state-owned PT PLN Nusantara Renewables to complete the development. The plant features 114,420 bifacial solar modules, 126 lithium iron phosphate battery packs and smart transformer stations to support sustainable energy needs.
The site will generate 93GWh of clean energy per year. This will fully power the new capital city, which was announced in 2022. The launch of this solar plant marks an important step in Indonesia’s energy transition. The country is working to expand its renewable energy sector. The project will help reduce reliance on fossil fuels and support sustainable urban development.
Jen Tan, head of renewables for Singapore and Indonesia at Sembcorp Industries, said: “Sembcorp is pleased to partner with PLN in this project. Leveraging our experience, we will deploy advanced energy storage to pair with the latest solar technology in this landmark utility-scale project.”
Indonesia’s Renewable Energy Goals
Indonesia aims to reach 75GW of renewable energy capacity by 2040. The country confirmed this goal during the G20 Summit in Brazil in 2024. Solar power is expected to play a crucial role in this transition.
Energy storage is vital for managing variable solar generation. However, battery deployment in Indonesia remains low. The government launched a 5MW pilot project in 2022, but large-scale storage development is still in its early stages.
Despite this, companies are investing in the sector. China-based Rept Battero recently announced an 8GWh gigafactory in Indonesia. This facility will focus on lithium-ion battery production for energy storage systems.
Challenges and Future Developments
Sembcorp had previously planned a larger solar-plus-storage project in Indonesia. This proposal included a 1GW solar plant and the largest BESS in Southeast Asia. Singapore relies on renewable imports due to land constraints. Solar projects like Sembcorp’s solar plant in Nusantara highlight Indonesia’s potential as a key energy partner.
Indonesia’s energy sector is undergoing rapid transformation. The government is focused on expanding its renewable infrastructure. The Sembcorp solar plant represents a major milestone in this effort. As demand for clean energy grows, Indonesia is expected to see further investment in solar and energy storage. The country’s ambitious targets suggest a bright future for the renewable energy industry.
The Nusantara solar plant is a strong step towards a greener Indonesia. The project sets a precedent for future large-scale solar developments. With ongoing investment and policy support, the country can achieve its renewable energy goals.
