EDF Energy, one of the UK’s ‘Big Six’ major energy suppliers, is seeking to build a portfolio of domestic batteries to take into energy services markets by offering discounted energy storage units to consumers via a new partnership with manufacturer Powervault.

Cloud-aggregated virtual power plants using residential or C&I battery storage as part of a smart energy management system can benefit the grid, integrate renewables and EVs and hopefully add a powerful long-term value proposition for home storage. Andy Colthorpe and David Pratt report on how some of the UK’s first VPP projects are proving the concept.

Energy storage and other flexibility providers with units as small as 1MW will soon be able to access ‘Great Britain’s core flexibility market’ under reforms being proposed by transmission system operator, National Grid.

Home storage systems have been considered an ‘early adopter’ market in many parts of the world, perhaps more important as a way that individuals can control their own green energy use and save energy than as a means of generating big money returns.

Shell, which has just participated in an investment round for sonnen, is one of the big players in the incumbent energy industry that “really acts” on clean energy, rather than just talking about it, sonnen’s CEO has said.

Shell has continued to scale-up its interest in distributed energy by participating in a €60 million (US$70.23 million) investment round by German battery storage firm sonnen.

Israel-headquartered SolarEdge launched a software platform for aggregating household energy storage units – and other distributed energy equipment – into virtual power plants, last week. The company’s solution has already been chosen for a VPP project in Australia by AGL, one of the country’s biggest utilities. The commercial launch of the VPP platform direct to customers is now underway. Andy Colthorpe spoke with Lior Handelsman, one of SolarEdge’s founders and vice president of marketing and product strategy.

Virtual power plants (VPPs) can greatly increase the value of home energy storage systems for a range of stakeholders including grid operators, utilities and their customers, according to SolarEdge, which has just launched a VPP software platform.

TEPCO, one of Japan’s national utilities and grid operators, will roll out home solar-plus-storage systems for its customers as part of a drive to create a renewable energy retail business.

Simply Energy, the Australian retail arm for ENGIE, will aggregate 6MW of Tesla household batteries together with 2MW of demand response at commercial premises in Adelaide in a project supported by the government-backed Australian Renewable Energy Agency (ARENA).
