At the beginning of September, Social Energy won the first ever fully domestic weekly Firm Frequency Response (FFR) contract with National Grid ESO. This saw the energy technology company utilise its fleet of over 5,500 domestic solar and battery storage systems within its network to respond to National Grid ESO calls, providing 4MW of FFR capacity throughout the day to help the operator balance demand. Previously, FFR capacity had largely been met by larger scale technologies, such as grid-scale batteries. But with domestic solar and battery systems becoming increasingly common – and the challenge of balancing continuing to grow as intermittent renewables take over from fossil fuels – there is an “enormous” potential for systems like Social Energy’s to help manage demand, as the company’s chief technology officer Steve Day explained.

A project using giant Tesla Inc. batteries was used to help balance supply and demand in Britain’s electricity market for the first time this week. The plant is made up of six Tesla megapack batteries that can store energy from renewable sources to be used at times of peak consumption. The National Grid Electricity System Operator uses the balancing market to fine tune supply and demand to make sure they match exactly. The cost of balancing the power market surged this summer as the effects of the coronavirus pandemic reduced supply and made usage harder to predict. National Grid spent 718 million pounds ($932 million) balancing the network from March to July to cope with low demand and high supply of renewable generation — that’s 39% higher than usual. A new computer system used by National Grid has allowed burgeoning technologies like batteries to be used in the balancing market more easily. Ideally batteries can draw electricity from the network when wind or solar supply is plentiful or even beyond what’s needed, and store it for use at times of peak demand.
