Occupancy in the week 19.–25.10.2026
On average, a charging point was occupied 8,5 % of the time, 10,9 % across Switzerland. The busiest hour was 13:00 with 15,9 % occupancy. We counted at least 505 charging sessions, 0,7 per charging point and day. 14 of 98 charging points had no charging session during the whole week. 9 charging points were out of service for at least 3 days in a row.
Charging at home
Charging at home for Aarau costs 25,17 Rp./kWh energy price at the local grid operator plus a basic charge of CHF 60 a year (tariff 2026). For 100 km that is about CHF 4.87 plus VAT, calculated with 18 kWh consumption and 6,9 % charging loss at the wallbox. For 2027, 23,36 Rp./kWh has been reported. At public charging points the operator’s price applies, not the grid operator’s tariff. The “Charging” tab shows what operators report.

Where the figures come from
- Electric cars: FSO, road vehicle stock by municipality, as of 2025, and new registrations 2025. Counted by the keeper’s address, so company cars are included. We do not show figures under 5.
- Charging points: SFOE, charging stations for electric cars (ich-tanke-strom.ch), daily export of 26.10.2026. The municipality follows from the coordinate and swisstopo’s municipal boundaries (swissBOUNDARIES3D).
- Occupancy: our own measurement from the SFOE status reports, every 3 minutes, week 19.–25.10.2026. The figures are openly available at /ladenetz-gemeinden.json.
- Electricity tariff: ElCom, tariffs reported by the distribution system operators, standard product, profile H5 (7’500 kWh a year, house with an electric car), excluding VAT.
What the figures do not say
- Private chargers in garages and at houses are not recorded centrally anywhere and are missing here. Most electric cars charge there.
- No reported charging point does not mean there is none: an operator who does not report its charger to the SFOE is missing from the file.
- Charging sessions are a lower bound. We count the change from free to occupied between two readings; a session shorter than three minutes is missed.
- Occupancy counts how often a charging point was reported as occupied. A car that stays parked after charging counts as occupied.
