Electric vehicles will soon be able to power up at 50-kilowatt charging stations on the Massachusetts Turnpike.

The state Department of Transportation plans to install fast-charging stations at six Mass Pike ?service plazas by the end of this year. The first — at the westbound Framingham and eastbound Natick plazas — should be ready for drivers to use by early fall.

EV charging stations at the eastbound and westbound Charlton plazas are expected to be operational by late fall. A charging station at the westbound Blandford plaza is scheduled to be in service by the end of the year, along with another location at either the eastbound Blandford plaza or eastbound Lee plaza, according to MassDOT.

“Each station is ‘fast charging’ and in about 10 minutes can charge an electric vehicle to about 80 percent power, and in about 20 minutes can charge a ?vehicle to about 100 percent power,” MassDOT spokeswoman Jacquelyn Goddard said. “MassDOT decided to install charging stations to support the growth and adoption of electric vehicles, and charging locations were chosen according to guidelines from the Department of Energy.”

The proposed locations for the EV charging stations are adjacent to the air-filling stations near the convenience stores at each plaza. Project costs include about $30,000 in equipment expenses per charging station, plus additional costs related to utilities infrastructure at each site, according to MassDOT.

MassDOT eventually plans to install a minimum of a dozen EV charging stations as part of the Massachusetts Clean Vehicle Project in partnership with the Department of Energy Resources. It’s also exploring Mass Pike charging stations for hydrogen fuel-cell electric vehicles.

The state agency cur-?rently is soliciting operators to run the fuel service facilities at Mass Pike service plazas through 2025, and the chosen company will be responsible for maintenance of the EV charging stations after the first year as part of the lease.
