When I look at my consumption graph, the biggest spikes are typically the stove and oven. E.g. normally, our average baseline (with fridge, freezer, TV etc.) was about 400W, but when my wife did a christmas goose in the oven, the power consumption went up to various values between 2000 and 3000W for several hours. On normal days, there's a shorter spike to about 2500W when the stove is on and some smaller ones, probably from vacuuming etc. So from my point of view, those peak values are the ones to look at.

Since last week, we have a swim spa. That also changes the graph significantly (even though we used a heat pump to lower the energy consumption)...
