HyperStrong has signed an agreement with ERS Energy and Gamuda for the development of the MyBeST Pekan Battery Energy Storage System (BESS) project in Pahang, Malaysia. The project will have a planned capacity of 100 MW/440 MWh and will form part of Malaysia’s efforts to expand grid-scale energy storage infrastructure and support the integration of renewable energy resources.
The project is among the first developments awarded under Malaysia’s Battery Energy Storage Programme (MyBeST), an initiative launched by the Energy Commission of Malaysia to accelerate the deployment of utility-scale energy storage systems. The standalone grid-connected facility will provide services including peak shaving, frequency regulation and grid balancing, helping to improve network flexibility, reliability and operational stability as renewable energy penetration increases. The project has also been designed to operate under Malaysia’s tropical climate conditions, including high temperatures, humidity and salinity levels.
The development supports the objectives of Malaysia’s National Energy Transition Roadmap and reflects growing investment in grid modernisation across Southeast Asia. HyperStrong will provide energy storage technology and system expertise, while ERS Energy and Gamuda will contribute renewable energy development, engineering and infrastructure delivery capabilities. The partners stated that the project could serve as a reference model for future large-scale battery energy storage deployments across the region.
