Battery company SolarEdge and Smart Metering Systems conducted the trial, revealing that battery-equipped homes outperformed those simply reducing appliance usage.
Customers were alerted ahead of “demand flexibility events” and paid for reducing their usage.
However, battery-equipped households had an advantage.
Smart Metering Systems sent a signal to charge their batteries from the grid before the event, allowing them to sell surplus power back at a higher rate, earning an average of £6.52 per event and up to £25.60 in one instance.
Data from six tests showed the highest-earning household making £100.61, while also alleviating grid strain more effectively.
Normal DFS households reduced grid burden by 0.5 kilowatt hours (kWh), whereas those with batteries relieved the system by 2.7kWh.
