Nope. More than 80% of my usage comes from heating and driving and I’ve heavily optimized car charging and heat buffering to make use of low cost times.

Heating can only be optimized for about 24h periods, that’s why I can supplement my heating with wood from my own forest.

Driving, between April and October pretty much only happens using electricity from my own roof, between May and September the entire house uses less than 100kWh from the grid.

Before I signed at Tibber, I had of course compared my recorded load profiles including simulations for automated usage optimization against EPEX 60min day-ahead prices and I would have been at less than 0.23€/kWh on average since 2020, including the high prices of 2022.
