Halcyon's BESS Tracker compiles information on newly proposed, in development, and under construction battery energy storage systems across the United States. The tracker was released in December 2025 with projects over 100 MW of capacity and began adding projects under 100 MW in.
Sonnedix Japan has brought online just under 500MW of solar PV in the country. Utility Osaka Gas and developer Sonnedix are installing a battery energy storage system (BESS) at the latter's 38. 7MW Oita solar project, which Osaka Gas described as the.
The Wellington Battery Energy Storage System project consists of a grid-scale BESS with a total anticipated discharge capacity of 500MW and a storage capacity of 1,000MW hours. Fluence Energy had the contract to design, supply, construct and commission the installation.
The CAPS BESS is an efficient, reliable and smart containerised energy storage system. It is designed to provide backup power, intelligent energy storage management and integration with a wide variety of inputs and outputs.
The project is earmarked to deliver 150MWp of solar PV power integrated with a 50MW battery energy storage system (BESS) to the national grid over a 25-year term.
P-type solar cells use boron-doped silicon while N-type cells use phosphorus-doped silicon, with N-type offering better efficiency potential (25%+) and reduced light-induced degradation (LID).
In 2025, the typical cost of commercial lithium battery energy storage systems, including the battery, battery management system (BMS), inverter (PCS), and installation, ranges from $280 to $580 per kWh.
