Nine electric vehicle charging stations have been set up in the Camden Yards stadium complex, near Oriole Park and M&T Bank Stadium.
The stations are available for fans on game days, and for tourists, employees of downtown businesses, or others.
The stations were created with a grant from the Maryland Energy Administration's Electric Vehicle Supply Equipment Rebate Program.
"Expanding the State's EV charging system infrastructure benefits drivers and local businesses," said Mary Beth Tung, the Maryland Energy Administration director.
The Maryland Stadium Authority said it partnered with the Electric Vehicle Institute on the installations.
Eight of the charging stations are Level 2 and one is Level 3, which has more power and requires less charging time.
The Camden Yards area also is joining the new Baltimore Bike Share program in the spring. The city has partnered with Bewegen Technologies on the system, which allows riders to pay by the month or by the trip.
