The two battery storage facilities use Storage GEM®, the innovative modular energy storage container technology developed by the Akuo Group. A total of 8 such containers have thus been deployed on Tongatapu, the Tonga archipelago’s main island: three Storage GEM® for Tonga 1 and five for Tonga 2.
[pdf] These systems use containers to house energy storage components such as batteries, inverters, and cooling systems, providing a compact and modular solution for energy storage. One of the main benefits of containerized energy storage systems is their scalability.
[pdf] Engineered to support both wind and solar energy, this outdoor system offers a high-capacity storage of up to 5 MWh, making it ideal for large-scale energy needs. Equipped with advanced liquid cooling technology, it ensures consistent performance and reliability even in demanding environments.
