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.
Battery storage technology costs will have to fall by a further 30% before projects in the UK are feasible without lucrative frequency response revenues, a leading investor has said.
Eelpower has commissioned a 10MW battery energy storage system (BESS) in England, backed with both frequency response and capacity market contracts, in the first of a new pipeline of projects being planned by the company over the next decade.
A representative of National Grid, the UK’s transmission system operator (TSO), has said that energy storage will be “integral” to the network’s flexibility strategy – while urging developers not to rely solely on early frequency regulation contracts.
Siemens has continued to bolster its UK presence with a new partnership with Grid Battery Storage Limited (GBSL) which will see a 22MW portfolio of four projects built and an ‘energy storage as a service’ offering launched.
The UK’s large-scale battery storage installations have reached 100MW of capacity, made up of around 50 individual sites larger than 250kW. Lauren Cook of Solar Media's Market Research team discusses how this point has been arrived at and what we might expect to see coming next.
Chris Pritchett of UK law firm Foot Anstey recently served as moderator for the “Developers and financiers debate” at the Energy Storage Conference at the Solar & Storage Live 2017 show in England. Afterwards, Andy Colthorpe caught up with Chris for an in-depth interview on camera.
UK electrical distribution system operator Northern Powergrid has begun using a £4 million (US$5.27 million) battery paid for by consumers to sell services to National Grid, despite plans from the national regulator Ofgem to prevent distribution network operators (DNOs) from doing so in future.
