As the battery storage market continues its strong growth trajectory, battery manufacturers are ramping up production to meet increased demand.

We analyse recent details that have emerged on battery OEM CATL’s zero-degradation BESS technology, which was first announced two years ago.

Some 9.1GW/33.5GWh of large-scale BESS came online globally last month, with Saudi Arabia accounting for over one-third of the figure.

Huawei FusionSolar’s new Smart String Grid-Forming ESS Platform, LUTERRA, is born from technology breakthroughs designed to drive customer success.

Liam Critchley takes a deep dive into battery state of health (SoH), one of the most important metrics for battery storage operational and lifecycle management.

Chinese system integrators have cemented their dominance of the global battery energy storage system (BESS) market, capturing 76% of global market share in 2025.

The state-owned Saudi Power Procurement Company (SPPC) has revealed the qualified bidders for its second build own operate (BOO) BESS tender, totalling 3GW/12GWh of capacity across six projects.

State of charge (SOC) is on the face of it a straightforward measurement for batteries and BESS. But in reality, it’s highly complex and under- or over-reporting still happens in the industry, leading to under-performance and losses in revenue.

In 2025, BESS installations surpassed 320GWh, a y-o-y increase of over 50%. While this tells one-side of the story, the growth in cell and system shipments tells an even more significant one, writes Benchmark’s Iola Hughes.

Envision has signed a 660MWh BESS supply agreement with SOLA Group and construction company WBHO in South Africa’s Free State.
