Model: 12 months at constant rates effective 1 February–31 December 2026, not actual calendar-2026 billing (January quality rates differed). DSO subscription assumes monthly billing and conventional reading. All monetary inputs and components are net; 23% VAT is applied once to the gross total. Enter energy prices including any contract excise, which is not added again. Check G12 hours with your DSO: the chart shows entered consumption only, not a timetable. Prosumers, special tariffs and reliefs are excluded.
