First Solar-Storage Integrated Project in Indonesia’s New Capital Successfully Connected to the Grid
On November 27 local time, the IKN 50 MW Ground-Mounted Photovoltaic and 14 MWh Energy Storage Project, jointly undertaken by China Energy Engineering Group Shanxi Electric Power Engineering Co., Ltd. (SEPEC) and Zhejiang Tiongkok Power Indonesia (ZTPI), successfully achieved grid connection. This milestone signifies a solid step forward for SEPEC in the renewable energy market of Indonesia.
The project marks the first solar-storage integrated project in Nusantara, the new capital of Indonesia, and is also the country’s first mountain photovoltaic (PV) project. The project features a total installed capacity of approximately 70 MW on the direct current (DC) side, a 20 MW/14 MWh energy storage system, a 150 kV step-up substation, and spans a construction area of around 70 hectares.
The project team adopted a localized management strategy, leveraging innovative solutions such as combining spiral pipe piles with aluminum alloy brackets to optimize construction and installation processes. Through precise resource allocation, stringent progress and quality control, and overcoming challenges such as limited local construction resources, variable mountain climate, complex terrain, and strict localization requirements, the team successfully met its goals and achieved grid connection on schedule.
The grid connection of the project enhances the sustainability of local energy supply, supports Indonesia’s transition to green energy, and significantly contributes to cooperation between China and Indonesia in renewable energy and infrastructure development. This accomplishment also serves as a driving force for green development under the framework of the Belt and Road Initiative.
