Living Lab data shows 48% EV uptake shifts peak demand to overnight, doubling traditional evening peak
Energy Systems Catapult's Living Lab analysis of 854 homes found that at around 48% EV uptake, the largest daily electricity demand spike moved from early evening to the middle of the night due to cheap overnight EV tariffs. At this adoption level, the new overnight peak is twice as large as the traditional early evening peak. The research, which uses real homes with EVs to simulate higher adoption scenarios, highlights how overnight charging strategies that work at lower adoption rates may strain local grids as EV numbers grow beyond the current two million battery electric cars in use in the UK.
Why it matters
Fleet operators relying on overnight charging strategies may face local grid capacity constraints as EV adoption scales, requiring network reinforcement or demand flexibility measures. The findings suggest procurement teams should factor in potential grid upgrade costs or smart charging requirements when planning depot charging infrastructure.
