Varta Storage, the energy storage division of consumer, automotive and industrial battery manufacturer Varta, is poised to enter the UK and Ireland residential battery markets through a new exclusive deal with Waxman Energy, as ‎global storage head Gordon Clements told our sister site Solar Power Portal the UK is “the next market that will start to open up” for the technology.

The UK’s Solar Trade Association (STA) has refuted claims made in a recent report that a residential solar array in combination with an energy storage system was not “economically viable”, calling it flawed and lacking in detail.

One of the largest rooftop solar installations in the UK is to add a Tesla battery in what is thought to be the first UK project to use a commercial PV array to charge an energy storage system to avoid grid charges and provide ancillary services.

There is no economic benefit from installing energy storage with solar PV in UK homes, a new study has suggested, adding that the cost of battery degradation would cost homeowners £400 (US$518) in the first year.

One of the distribution network operators (DNOs) tasked with maintaining security of electricity supply into British homes is launching a tender for flexibility services that include energy storage.

British investment trust, The Renewables Infrastructure Group (TRIG), has become the latest investor to enter the large scale energy storage market after buying a 20MW project from RES for £20 million (US$25.9 million).

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.

Residential battery storage has won a partial victory after the UK government agreed to a tax break for battery systems, but only if they are supplied and installed alongside solar panels.

What is claimed to be the UK’s largest stand-alone battery storage facility has been successfully commissioned by Hazel Capital as the investor continues to build its energy storage project portfolio.

Distribution network operator (DNO) UK Power Networks (UKPN) has launched a new fast-track application process for small scale electricity storage just days after Britain’s government solidified its support for the technology with funding allocations and new regulatory proposals.
