In a small sauce pan, whisk together sugar and water. Bring to a boil, reduce heat and simmer for 10 minutes. Remove from heat, pour simple syrup into a jar, and place in the fridge until ready to use.
In a large pitcher prepare iced tea according to the package directions.
Place chopped peaches in a blender, and puree until smooth. Pour through a fine mesh strainer to remove any pulp.
In a punch bowl or very large pitcher combine iced tea, peach puree, and the most of the simple syrup (reserve some to adjust to your taste). Stir to combine. Taste and add additional simple syrup if desired. Just before serving mix in ginger ale. Serve over ice.
