Utility E.ON and battery storage engineers redT have partnered to install a demonstration solar-plus-storage system at the HQ of warehousing and logistics firm JB Wheaton in Somerset, England.

Germany, until recently the leading European nation for installed PV capacity, extended a scheme to support purchases of lithium-ion energy storage systems for solar at the beginning of this year.

It would be unfair to put the burden of paying for the rollout of smart meters onto German households with PV-plus-storage when the devices would primarily benefit grid operators, trade association BSW Solar has said.

Microinverter maker and energy management specialist Enphase has started taking orders from installers for its AC battery for home PV systems in Australia and New Zealand, with shipments to start arriving in August 2016.

Oil and gas company Total has proposed to buy battery company Saft, which produces devices for the stationary storage industry as well as for transport and other applications.

Global maker of construction and mining equipment Caterpillar has launched an integrated micro-grid solution which combines solar PV and energy storage with the company’s power generation equipment.

SolarCity, one of the biggest names in US residential solar, has announced a new set of services targeted at utility and grid operators including the official launch of its grid-scale solar-plus-storage offering.

Tucson Electric Power (TEP), a utility in Southern Arizona with around 420,000 customers, has received approval to build two 10MW energy storage systems, including one co-located with solar, from the state’s regulator.

An influential German think tank and a national energy storage industry association have both said that long-term solutions need to be found for residential solar-plus-storage owners’ part-time reliance on the grid.
