Green Mountain Energy was the first supplier (ESCO) in New York City fully dedicated to cleaner energy. Since 2000, we have been an active participant in the development of energy competition for New York and helped support the development of New York's first wind farm, the Madison Wind Project in Madison County. We've provided renewable energy products to National Grid customers in Upstate New York since 2002. In August 2009, we entered the competitive market in New York City and Westchester County, expanded into Orange & Rockland in March 2012, and began offering direct access service in National Grid as well as Central Hudson, New York State Electric & Gas (NYSEG) and Rochester Gas & Electric (RG&E) service territories in June 2013.
Green Mountain Energy is the nation's longest-serving renewable energy retailer. We were founded with the mission to change the way power is made – something that sets us apart from all other suppliers. We offer electricity plans that use energy from renewable sources like wind and solar. The traditional production of electricity from fossil fuels is the largest source of industrial air pollution in the U.S. When you choose cleaner electricity from Green Mountain Energy, you help make a difference for the environment.

The monthly customer charge is a flat amount added to your monthly invoice regardless of usage. For our New York customers, the charge is a daily amount multiplied by the number of days in the billing cycle.
There are two main things that determine the amount of your invoice: the amount of electricity you use during the month and the rate you’re paying per kilowatt-hour (kWh) for that electricity, or:

Even after you choose an energy supply company, your utility will still be there to read your meter, handle service calls, and provide emergency assistance. Energy competition is also supported by the State of New York.
