The Simpsons do not have a New England Accent, so no It is not CT, Mass, NY, or anywhere in th' northeast. It is clearly Springfield, IL...If you look at a map of Springfield, IL and compare it to the Springfield, Simpsons...there is a similarity...The power plant in Springfield, Mass does not look like the one on the Simpsons, however the one in Springfield, IL does.
