Calculation assumptions and sources

Applied settings

15,000 km per year · 70% charged at home · 30% in public DC · G11 — flat rate · All networks

Real-world consumption

Mild weather: 165 Wh/km

Cold weather: 224 Wh/km

Cold-weather share: 44.2% from the 1991–2020 climate normals, source read on September 13, 2026. IMGW-PIB source

The source does not state whether these figures include charging losses; no additional loss factor is applied.

Tyre ageing without mileage is excluded; seasonal changeovers are counted twice per year.

Home tariff

G11 — flat rate: PLN 1.10/kWh · source read on September 13, 2026 · Poradnia OZE; assembled from URE-approved PGE 2026 tariffs

Indicative reconstruction: PGE Obrót energy, PGE Dystrybucja variable distribution and variable statutory charges from the 2026 tariffs were summed net and increased by 23% VAT. Fixed monthly fees are excluded. The result is below the shared G11 range of PLN 1.18–1.32/kWh because it includes variable items only; published comparisons may include other charges or assume a different billing profile.
