Balancing the electricity supply system is not a simple task anywhere in the world, especially as more and more distributed energy resources come online. OpenADR can kick in, whenever the grid operator needs to reduce demand to keep the system stable. Aric Saunders of Electriq Power explains.

Powin Energy has launched a set of three battery storage system products using CATL’s large form factor lithium-ion cells, including a system solution capable of 4+ hour duration and backed by a 20-year warranty.

Ensuring battery systems used in conjunction with solar perform safely and optimally is essential in the continued roll-out of storage technology. Robert Puto and Gerhard Klein of TÜV SÜD examine independent technical assessments that must be undertaken before a storage system is built.

Commercial energy storage ‘pioneer’ Stem Inc and NEC have announced a master supply agreement and wide-ranging partnership that will see the latter’s equipment and solutions used in solar-plus-storage projects in Stem’s pipeline.

We also asked what it means for the company to now be under SolarEdge’s ownership, why effective management and control of batteries may be a more important safety question than just which battery chemistry to choose.

A 100MWh battery energy storage system has been integrated with 400MW of wind energy, 200MW of PV and 50MW of concentrated PV (CPV) in a huge demonstration project in China.

Tesvolt has claimed its new commercial energy storage system pushes the boundaries of what can be achieved in such devices for modularity and safety.

Battery management systems developer Dukosi announced that it has secured approximately US$2.4 million in funding, led by IP Group.

In a two-part video interview with PV Tech Storage, Wolfram Walter, founder of battery manufacturer ASD Sonnenspeicher, said electricity storage suffered from an image problem. He describes to Andy Colthorpe how his company is marrying cutting-edge technology with cool design to appeal to a broader market.
