The EU’s lack of regulatory definition for energy storage is among major factors holding back the potential of the technology in the continent, particularly for integrating renewables, Solar Power Europe has argued in a new report.

Australian battery developer Redflow has launched what is thought to be the first residential-level storage device to use a flow battery, in its home market.

A hybrid off-grid project from renewables firm Energy Developments Limited’s (EDL) including 4MW wind, 1MW solar and a 1MW/250kWh battery system in South Australia has reached financial close.

Many have predicted 2016 will be the year when energy storage starts to live up to its hype. Andy Colthorpe canvased views from some of the leading figures and companies in the sector on the next developments a market that could help take solar and other renewables to the next level.

In the second part of our video interview with Sonnen’s UK director, Martin Allman, we look into the future. We talk smart meters, community energy trading, which steps forward Britain is ready to take – and why the industry needs to walk before it can run.

What is thought to be Canada’s first virtual power plant (VPP), aggregating the capabilities of a small fleet of solar PV-plus-storage systems with energy management software, has been deployed in Ontario.

Sonnen, Germany’s market leader in residential energy storage, recently launched its operations in Britain. We met up with Martin Allman, the company’s UK country director, to hear about key aspects of the company’s strategy.

For over a decade, net metering has been a crucial component of the economic puzzle for renewable energy, allowing both residential and commercial rooftop PV owners to realise favourable returns on their solar equipment investment. John Merritt of Ideal Power Conversion looks at some of the arguments and counter-arguments and says solar-plus-storage could be the natural successor to the policy – starting at commercial and industrial (C&I) level.

Puerto Rico’s financially troubled electric power authority PREPA will install a large-scale battery park at a 10MW PV farm, to help integrate the farm’s output and other renewables.
