Measuring Large-Scale Energy Demand Flexibility: Evidence from a Nationwide Natural Field Experiment 1: Centre for Net Zero, United Kingdom; 2: Columbia University, United States of America The integration of renewable energy sources into the grid is increasing the value of domestic demand flexibility. This study evaluates the world’s first and largest domestic and commercial nationwide demand flexibility program. We analyzed this policy by randomizing 2.7 million residential and business customers to receive demand flexibility payments. We also randomized the incentive levels and staggered invitations. We found that these events led to a 25\% reduction in overall peak grid demand, with an average cost of £3,000 per MWh. We also found that reduction per opt-in was fairly consistent; variations in aggregate energy response mostly came through changes in customers' opt-in rate. Opt-in was relatively price-elastic, with a 140\% increase in opt-in for a doubling of payment per demand reduction. Notably, customers did not exhibit fatigue between and within event ``seasons''. The most significant reductions in peak demand were observed among households utilizing low-carbon technologies, such as solar panels, heat pumps, and batteries. | |
