A zinc-air energy storage system (ZESS) offering 10 hours of storage is being trialled in a New York Power Authority (NYPA) project, while a US Department of Defense-funded investigation into flow batteries has moved into a physical validation and evaluation phase in Colorado.

A spokesman for S&C Electric has confirmed the company will no longer be producing its power conversion system (PCS) for energy storage systems but will remain in the market as a system integrator.

Utility company Ameren and smart grid company S&C Electric Company announced that they have conducted a successful 24-hour islanding test in August at the recently deployed Ameren microgrid in Champaign, Illinois.

To mark the launch of the new-look Energy-Storage.News site, our team profile six of the leading global system integrators working in energy storage today.

Renewable Energy Systems ranks alongside US firm AES at the top of a new leader-board of energy storage systems integrators; its two new National Grid contracts will see it top the table, it says.

The trial of a 6MW/10MWh ‘Big Battery’ has proven energy storage can help Britain’s electricity network, but the next crucial phase is to assess the business case, the grid operator which commissioned it has said.

Later this year, the 21st annual session of the Conference of the Parties (COP 21) will take place in Paris. Leaders from around the world are coming together with an overarching goal of creating a deal to support the reduction of greenhouse gas emissions to limit the global temperature increase to 2°C above pre-industrial levels. Key to the reduction of global carbon emissions is the transformation of our energy networks, by adopting cleaner, more efficient and smarter technologies, writes Andrew Jones.
