The UK’s Institution of Engineering and Technology (IET) has published its long-awaited Code of Practice for Electrical Energy Storage Systems, filling what has been described as a vacuum of clear guidance for installers and their customers.

Arizona Public Service (APS) announced Wednesday that rather than rebuild miles of electricity transmission lines, it will install two battery storage systems totalling 8MWh in rural Punkin Center, Arizona — making it one of the first electricity companies in the US to utilise batteries instead of traditional infrastructure.

Nidec ASI will be installing 5MW / 5MWh of battery energy storage at a utility-scale wind farm on the French island territory of Martinique, aimed at stabilising and maximising the flow of energy onto the grid.

The sale of an NEC Corporation business division involved in manufacturing lithium-ion batteries will have no material impact on the group’s activities in energy storage, according to a company spokesman.

There is a global trend towards longer duration energy storage and even in this segment, lithium-ion batteries are expected to dominate the market over flow batteries and other technologies, an I.H.S Markit analyst has told Energy-Storage.News.

French energy storage developer and system integrator Electro Power Systems (EPS) has hailed the speedy execution of a microgrid’s expansion in Somalia, which has just been completed in less than 30 days.

Primus Power, a flow battery maker which claims its systems can cost less than half the price of lithium-ion energy storage over its lifetime, is establishing manufacturing lines in China.

Developer Deepwater Wind has applied to build a 144MW offshore wind farm, coupled with 40MWh of battery-based energy storage from Tesla, off the coast of Massachusetts.

Australian energy firm Genex Power has received first-round board approval from the Northern Australia Infrastructure Facility (NAIF) for potential debt funding of its 270MW solar PV and 250MW pumped hydro projects, that are part of the Kidston Renewable Energy Hub, in Northern Queensland.

BYD has announced a tie-up with the inverter manufacturing division of Kostal, where the former’s latest high voltage energy storage systems will be paired with the latter’s PIKO brand inverters.
