Several significant developments in battery energy storage systems (BESS) have emerged globally, highlighting the increasing demand for renewable energy solutions. In Calderdale, UK, Sandbrook Capital BES Ltd has submitted plans for a new electricity storage facility that will utilize 60 battery units to manage energy supply from the National Grid. Meanwhile, Natron Energy has announced a $1.4 billion investment in a gigafactory in North Carolina to produce sodium-ion battery cells, aimed at dramatically increasing production capacity. In the Highlands of Scotland, local councillors have raised concerns regarding proposed BESS systems, emphasizing the need for environmental impact assessments due to potential biodiversity effects. Barbados Light & Power is seeking increased BESS capacity to support its growing photovoltaic installations, as approved systems fall short of current needs. Finally, the Romanian company Monsson Group plans to install a total of 1.5 GWh of battery storage by 2030, aiming to meet the rising demand for energy storage in conjunction with the renewable energy sector.
