Malawi’s energy minister was on hand last week as the southeast African country inaugurated its first large-scale standalone battery energy storage system (BESS).

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.

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

To avoid pitfalls that harm BESS investments, developers must sign well-structured contracts, writes Intertek CEA’s Yilin Huang.

Liam Critchley examines the modelling, safety standards and analytics that aim to mitigate the risk of thermal runaway in lithium-ion battery energy storage systems (BESS).

Liam Critchley examines a selection of third-party technologies for preventing thermal runaway events in battery storage systems.

Solar-plus-storage projects are proliferating across the globe and necessitate a choice between DC and AC coupling. In this piece we look at the differences and pros and cons of each.

The transition to new energy technologies, including grid-scale and vehicle batteries, can help fossil-fuel-dependent countries improve their energy security.

Solar PV and wind are now the cheapest sources of power, with co-located hybrids increasingly delivering round-the-clock electricity at fossil fuel-competitive costs in high-resource regions, according to a new report by IRENA.  

South Africa’s TSO Eskom and energy storage technology firm Energy Vault have partnered to deploy projects using the latter’s gravity-based technology.
