What are the P1, P2 and P3 time slots and how do they affect me?

These are the three periods into which your consumption is classified. P1 (Peak) applies Monday to Friday from 10:00–14:00 and 18:00–22:00, and is the period when market prices tend to be highest. P2 (Mid-peak) covers the remaining weekday hours, at an intermediate cost.

P3 (Off-peak) applies at night, on weekends and on public holidays, and is where prices tend to be lowest. With the Tarifa Transparente, shifting more of your consumption to P3 and less to P1 can significantly reduce your bill.
