More than 500 residential energy storage batteries will be aggregated into a virtual power plant (VPP) by US utility Portland General Electric (PGE), with some participating households offered US$5,000 rebates on battery system purchases as well as money off their monthly electricity bills.

AutoGrid has been developing “co-optimisation” capabilities that will allow residential battery storage deployed to mitigate power outages to continue participating in market opportunities.

For Japan, the famous 4Ds of the energy transition – creating a distributed, decarbonised, decentralised and digitised grid – will involve a huge scaling up of smart solutions on a market basis, various sources have told Energy-Storage.news.

Centrica and sonnen have completed a virtual power plant (VPP) project in the south of England, which will allow customers to maximise the potential of their solar panels while providing flexibility to the grid.

A regulatory framework put in place by Italy’s grid operator TERNA has enabled Enel X to aggregate residential energy storage systems to pool their capabilities.

International battery brand Duracell is set to launch a home energy storage system in partnership with a UK energy supply and services company which claims it has enabled big increases in revenues available to owners of the devices.

Virtual power plants, flow batteries and the economics of lithium-ion battery degradation are the focus of three feature-length articles, available now in the latest edition of Solar Media’s quarterly journal PV Tech Power.

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.

PV manufacturers Hanwha Q Cells and Sunpower have both signed deals to bring home energy storage to residential solar customers in Europe and in the US respectively.

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.
