Where did thomas Edison invent the elctrical generating system?

When visiting Roselle, New Jersey, I saw a plaque near the Roselle Park train station that says "First village lighted by electricity...". The actual invention may have occurred at or near his home in West Orange, New Jersey, but since he was called the Wizard of Menlo Park, maybe he had a lab there. (Today, Menlo Park is a section of the City of Edison.)
