China Southern Power Grid International (Hong Kong) Company has signed a cooperation agreement with Indonesia’s State Electricity Company (PLN) to jointly explore the development of energy storage in Indonesia. Announced on July 24, the partnership aims to align Indonesia’s energy infrastructure with modern storage technologies by conducting targeted research and providing actionable solutions. The Chinese firm will contribute its expertise in energy storage planning, investment, construction, and operations, supporting Indonesia's efforts to modernize its power grid and shift toward renewable energy.

According to the source, the collaboration will focus on five key areas: long-term energy storage development planning, investment policies, electricity pricing mechanisms, technical solutions, and safety-health-environment standards. By tailoring strategies to Indonesia’s current grid structure and energy demands, both parties aim to generate system-level, replicable models for managing energy transition. The agreement also signals an expansion of China Southern Power Grid’s regional influence, offering a model for broader Southeast Asian energy initiatives.

The project will be jointly implemented by China Southern Power Grid International (Hong Kong) Company and China Southern Power Grid Energy Storage Company. The Hong Kong office will serve as a platform for international operations, while the energy storage division will provide technical guidance. The agreement represents a strategic move to integrate China’s “Southern Grid Solution” into global energy transformation efforts.
