According to Uppsala kommun, the night rate is about 25% below the market average for public charging in Uppsala, while the day rate is about 25% above. Paul Eskilsson, chairman of the Uppsala parking board, said that directing more charging to night can use electricity grids more efficiently because total consumption and electricity prices are normally lower then. The differentiated pricing is a six-month test, after which the municipality will evaluate its impact on charging habits, revenue, and grid load.
The current market average prices for public charging in Uppsala have not been specified, and it is unclear how many charging stations are affected. Success metrics and potential adjustments after the evaluation have not yet been disclosed.
