Con Edison traces its origins to the New York Gas Light Company, founded in 1823. Over time, it merged with and acquired over 170 companies, becoming a leading energy distributor. It played a key role in New York's gas, electric, and steam services, including operating the world's largest commercial steam system. In 1998, following deregulation, Con Edison became a holding company. It has since focused on renewable energy, investing heavily in solar and wind projects, though it sold its clean energy business to RWE in 2023.
