Why is Octopus offering free electricity at the weekend?

Two reasons: to reward you for being an awesome customer and to encourage you to help make the energy system cleaner and cheaper to run by shifting a chunk of your energy use to off-peak times.  

When energy demand is at its highest (usually around teatime), the network sometimes fires up expensive fossil fuel generators to keep up. Weekends are a different story: on Saturdays and Sundays, electricity demand drops but there’s more clean, renewable energy to use up.

By giving you Happy Hours at the weekend, we can reward you for shifting your energy use away from busy times. You get to do some of the household admin for free – and together we can soak up excess renewables from the grid. A win all round!
