Electric vehicle owners can now roll up to the Mall and charge their cars.

The National Park Service announced today that there are two new charging stations available for public use: one on Madison Drive, across from the National Museum of American History, and another on Jefferson Drive, across from the National Air and Space Museum. They cost $2.00 an hour to use.

“As the National Park Service prepares for its second century of service to the American people we are committed to providing clean and green energy to promote a healthy environment,” National Mall and Memorial Parks Acting Superintendent Karen Cucurullo said in a release. “These charging stations contribute to our ongoing goal of energy conservation and efficiency on the National Mall.”

Clean Cities National Parks Initiative gave a grant for the project.
