Changes to the de-rating factors for battery storage projects competing in the UK’s Capacity Market (CM) will push the sector towards longer-duration batteries, while potentially sparking a shift towards energy arbitrage as a source of revenue for shorter duration applications. David Pratt heard from several industry sources following last week’s announcement.

Future battery energy storage projects in the UK have been hit with a major blow after the government published its intention to lower the de-rating factor in capacity market auctions by almost 80% for 30 minute duration batteries.

Panellists at the opening day of Solar and Off-Grid Renewables Southeast Asia event in Bangkok warned that investors who come on board quickest are going to gain a huge advantage as solar-plus-storage starts to become viable at scale.

Anesco is investigating how it could adopt flow batteries into future projects instead of lithium as a response to growing uncertainty around the future of storage de-rating in the capacity market, Clean Energy News can reveal.

A US state-backed organisation is partnering with the government of Singapore to build and test up to three energy storage systems using a variety of technologies on the island state.

EV manufacturer and battery specialist Tesla Motors has reported strong results with a return to profit in Q3 this year and expectations of this positive performance to continue into Q4.

The rapid march of energy storage batteries into the energy system is one element of a wider market transformation that is “terrifying some players as much as it is thrilling others,” according to the new chair of the Australian Renewable Energy Agency (ARENA) Martijn Wilder.

As more and more Australians look to energy storage solutions, a set of installation guidelines from the Clean Energy Council (CEC) has been released for industry and consumers which will be mandatory for installers accredited by CEC schemes by October.

Two initiatives have got underway in Europe, one in Germany and the other in Britain, aimed at accelerating battery development for electric vehicles and stationary storage respectively, while vacuum cleaner company Dyson has pledged a US$1.44 billion commitment to batteries – for cordless cleaning devices.

Placing a battery onto the grid is an economic investment. Matthew Hunt from the UK’s Chargesync discusses strategies for extracting the maximum value from devices and systems through optimising performance.
