Committee in its report of 15thOctober 2016 urge

the energymarket to embrace these smart solutions noting that potentially£7 billion in savings to consumers and businesses coul d be achieved. Participants can enj

gy storage is the key enabler to all

this. The principle source of revenue is from FirmFrequency Response (FFR). FFR is offered by the Grid to participating organisations to enable it tomanage the rises and falls of frequency caused by

corresponding peaks and troughs in demand. Lithiumion batteries are ideally suited t o performing FFR tasks as they respond quickly and benefit fromfrequent charging and discharging cycles. Sowhy aren’t energy sign up?Because there andbarriers toentry re

nclude things like, battery ensive. This isn’t true as

batteries usually carry a 15-yearwarranty and the payback on investment iswellwithin that time period. Typically, the financial returns on capital range from11%to 20%or more using the internal rate of return (IRR) metric. Flexible finance options are also offered by storage developers.

Another asumption is that DSRwill impact your business operations. Again not true. It will not have any discernible impact. Typically a battery storage systemwill respond in 20milliseconds to an event. This is seen as a seamless transitionwhen the battery automatically switchesmodes fromdischarge to charge or vice versa. Employees report they don’t even see the lights flicker. A contractwill include pre- set parameters for responding (or not) to Grid requests to use an organisation’s stand-by assets. Are

ganisationswill even ver be askedt their processes tohelpbalanceGri as some suppose. Large companie teamswho under
