Half a million dollars, that's how much it is costing Tennessee taxpayers to keep lights on 24/7 at the Leglislative Plaza and War Memorial Building in Nashville.
The Tennessee Department of General Services is in charge of maintaining Legislative Plaza.
A department spokesperson says the lights are needed so people can find their way out around the building in an emergency.
The plaza doesn't even have light switches in the offices.
Lawmakers recently approved renovating the plaza, and updating the electrical system.
