Summary
Using a Mercer County electric vehicle charging station costs $1 per hour for the first four hours under County Code § 5.05.02, rising to $5 per hour after that until the vehicle is fully charged. Drivers get a thirty-minute grace period once charging finishes, then pay a $10-per-hour occupancy fee until they move the vehicle.
Owners/operators of electric vehicles shall be charged $1 per hour, for the first four hours of use. After the four hours, the rate will increase to $5 per hour until the electric vehicle is fully charged. ... After the electric vehicle is fully charged, the owner/operator will be allotted a thirty-minute grace period to end their charging session and remove their vehicle from the designated electric vehicle charging station. After the thirty-minute grace period, the owner/operator will be charged an occupancy fee of $10 per hour until the vehicle is removed from the designated electric vehicle charging station.
Full Breakdown
05 of the Mercer County Code, adopted September 23, 2021 by Ordinance No. 2021-4, governs the County's own public charging stations. 02(B) requires drivers to 'activate and use the applicable mobile application, or activated user card, as provided by the County's maintenance and service vendor' before they can access the equipment; there is no walk-up or cash option. 02(D) then gives the driver 'a thirty-minute grace period to end their charging session and remove their vehicle from the designated electric vehicle charging station' once it is fully charged; after that grace period expires, the County charges 'an occupancy fee of $10 per hour until the vehicle is removed from the designated electric vehicle charging station,' which functions as a de facto overstay penalty rather than a charging fee. 03 additionally requires users to 'comply with posted rules and regulations regarding the use and operation of the charging stations' at the specific site.
Violations & Fines
There is no separate criminal penalty written into Chapter 5.05; enforcement runs through the fee schedule itself. Leaving a vehicle plugged in, or simply parked, at a County charging station past the thirty-minute post-charge grace period in § 5.05.02(D) triggers a $10-per-hour occupancy charge that accrues automatically through the mobile app or user-card account until the vehicle is moved.
