Duquesne Light plans to install electric vehicle charging stations at two lots owned by the city of Pittsburgh.

Charging stations for four electric cars will be placed at a city-owned lot at 6112 Kirkwood St., which the Pittsburgh Parking Authority leases from the city.

The DC fast chargers will allow people to charge their vehicles in about 20 minutes, said Dan Onorato, the authority’s executive director.

Vehicles will be allowed to park at the chargers for up to two hours, Onorato said. There likely will be an extra fee for charging, but the details haven’t been finalized, he said.

The new electric charging stations will add to the 35 stations the authority already has throughout the city, Onorato said.

Phipps Conservatory and Botanical Gardens also is expanding its electric vehicle charging capabilities. It plans to add four new dual plug charging stations on its Oakland campus, bringing its total to 11, said Michelle Allworth, Phipps’ facilities project manager. Three of them will be part of Duquesne Light’s program, and Phipps will pay for the fourth.

All of the existing charging stations at Phipps are reserved for staff, board members and volunteers, Allworth said.

“We will have a software with the new EV stations that will allow us to monitor the usage for the first time, so we will be able to track and pursue putting them online for public access and use at a later date,” she said.

The chargers set to be installed at Phipps can provide about 30 to 35 miles of range per hour of charging, Allworth said.

“Since most EV charging is done at home, this is a convenient way to top off when out and about,” she said.

Pittsburgh City Council approved plans for the new charging stations on Tuesday. There will be no cost to the city.

Duquesne Light expects both projects to be finished this year, Battaglia said.

“Duquesne Light Company is continuing to work toward our vision of a clean energy future for all, and a key part of this vision is empowering all our customers to experience the benefits of clean, electric mobility,” Duquesne Light spokeswoman Alyssa Battaglia said in a statement.
