Pennsylvania FAQs

Green Mountain Energy is the nation's longest serving renewable energy retailer.  Green Mountain was founded in 1997 with the mission to change the way power is made, and over a decade later we remain 100% committed to this mission.  Every single product offered by our company has an environmental benefit.

Since Green Mountain's inception, our customers have helped avoid more than 19.4 billion pounds of carbon dioxide emissions by choosing renewable energy, which is like taking over 1 million cars off the road for a year.  Our customers' demand has also helped spur the development of over 50 new wind and solar facilities across the nation.  Now that's making a difference!

Green Mountain was one of the first Electric Generation Suppliers (EGSs) to offer Pennsylvania consumers a choice of how their electricity is made, back in 1998 when the energy market opened to competition.  The demand of Green Mountain customers in Pennsylvania helped lead to the development of the first utility-scale wind farm in the Eastern U.S., in Somerset County, PA back in 1999.

Green Mountain reentered Pennsylvania’s PECO and PPL service territories in June 2012, and Duquesne Light’s service territory in December 2012, as an active EGS serving residential and business customers with cleaner energy. We are now, as we were in 1998, an active leader in promoting energy choice at the Pennsylvania Public Utility Commission.

Green Mountain is the nation’s longest serving renewable energy retailer.  We believe in using wind, sun and water for good, something that sets us apart from other Pennsylvania electricity suppliers. We are 100% committed to cleaner energy, and offer these products at a competitive rate.

Green Mountain is dedicated entirely to renewable energy. Green Mountain offers PECO, PPL, and Duquesne Light customers 100% renewable Pollution Free^™ electricity made from domestic wind. Plus, Green Mountain offers the highest solar energy content of any of any electricity supply product in Pennsylvania through our Pollution Free Gold^™ product.

Green Mountain offers multiple service plan options to fit every customer’s budget and lifestyle.

Green Mountain is offering Pennsylvania residents the choice of cleaner electricity products for their home, made from renewable sources like wind, water and solar.  Did you know that the traditional production of electricity from dirty sources like coal is the largest source of industrial air pollution in the U.S.?  By choosing clean Pollution Free^™ electricity from Green Mountain, you can help reduce your household’s share of carbon dioxide (CO₂) emissions and help fight climate change. Choosing renewable electricity products also helps encourage the development of new renewable, pollution-free generation facilities in Pennsylvania and nearby states.  The demand of Green Mountain customers in Pennsylvania helped lead to the development of the first utility-scale wind farm in the Eastern U.S., in Somerset County, PA back in 1999.

In addition, for every new customer sign-up Green Mountain is donating $1 towards the Pennsylvania Horticultural Society’s “Plant One Million” tree program.

No.  Your electric distribution company (PECO, PPL or Duquesne Light), supports energy competition and encourages customers to choose an EGS that is right for them.  The electric distribution company’s primary business role is energy delivery, and Electric Generation Suppliers (EGSs) are in the business of energy generation.  Even after you choose an EGS, your electric distribution company will still be there to read your meter, handle service calls, and provide emergency assistance.  Energy competition is also supported by the Commonwealth of Pennsylvania, the Public Utility Commission of Pennsylvania, and the Pennsylvania Office of Consumer Advocate.

According to the United States Environmental Protection Agency, making electricity creates more CO₂ than any other U.S. sector and is the #1 cause of industrial air pollution in the U.S.  Choosing Green Mountain Energy electricity products helps encourage the development and continued operation of new renewable, pollution-free generation facilities.

Green Mountain Energy offers Pennsylvanians the choice of two electricity products that use cleaner renewable resources: Pollution Free^TM electricity and Pollution Free Gold^TM electricity.  Green Mountain offers these products at competitive rates in month-to-month and Reliable Rate (12-month) plans to meet your needs.  Learn more by visiting our Products & Rates page.

# kWh used * cents per kWh rate = Generation Charge
