Stony Brook University installed six new charging stations for electric vehicles to its main campus this summer, bringing the number of stations to 10.

Each station supplies electricity to two parking spaces in the stadium parking lot, administration parking garage, life sciences and heavy engineering lots, as well as a lot located off Lake Drive, according to a news release.

"The new charging stations have been installed in proximity to the Academic Mall, thereby encouraging our community to use plug-in vehicles, which have less of an impact on the natural environment," said James Ambroise, the university's transportation and parking site manager, in a statement, adding that all stations will be operating by late August.

The new stations support an increasing number of students, faculty, staff and visitors who drive plug-in vehicles and seek energy resources on campus, school officials said.

The university's four existing stations, located at the Advanced Energy Center in the Research and Development Park, were installed about three years ago at a cost of $5000 to $7000 each, officials said.

Those were provided through Gov. Andrew M. Cuomo's 2013 Charge New York Initiative at no cost to the university. The cost of the new stations was not immediately available; school officials said they would be paid for through parking fees.

Cuomo's initiative aims to create a statewide network of up to 3,000 public and workplace charging stations and to support 40,000 electric vehicles on the road by 2018.

The university's charging station fee is $3 per hour, per space.

The stations accept credit or debit card payments only.
