When are you charging your car and washing your clothes?
Peaks in electricity consumption put a massive strain on the grid. When everybody comes home from work, starts charging their electric car, starts the washing machine, and turns on the stove to prepare dinner, the grid is heavily loaded. Your frient helps you help the grid.
With the frient EMI Norwegian HAN, you can identify when your usage peaks, helping you move some of your consumption to off-peak periods.
