is not justmore he solution to


generation, but tomake the Gridwork better The key is to balance the peaks and troughs of electricity demand. Through its Power Responsive* initiative, theNational Grid is actively promoting demand side response (DSR) to energymanagers across public and private sectors. TheHouse of Commons’ Energy


ge gy and Climate Change


Committee in its report of 15thOctober 2016 urge


ged the Government to encourage


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

additional income streams fromDSRwhen an on-site storage


by asset the Grid can call on. Energy


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
