The power is always greener on this side of the mountain. Green Mountain Energy, a NRG Energy company, buys and resells green power generated from hydroelectric, solar, wind, geothermal, and natural and landfill gas facilities. Since 1997 it has helped develop more than 50 wind and solar renewable facilities around the US. The company's renewable energy facilities have been responsible for avoiding the use of more than 19.4 billion pounds of carbon dioxide emissions, a primary contributor to global warming (or the equivalent of taking 1.7 million automobiles off the road).
Green Mountain Energy serves residential and commercial customers in New York City, Pennsylvania, and Texas, and partners with Portland General Electric as well as some New Jersey utilities that offer renewable energy through multiple suppliers. The company also provides carbon offsets (emission reduction credits from other projects that produce less greenhouse gases) nationwide to commercial and individual customers.
In 2011 Green Mountain Energy secured a contract from the iconic Empire State Building to supply it with 100% renewable energy (wind-generated power). The owners of the landmark building signed a two-year contract to buy 55 million kWh of renewable energy per year, avoiding the annual output of nearly 100 million pounds of carbon dioxide. The deal makes the Empire State Building New York City's largest commercial purchaser of 100% renewable energy.
Expanding its geographic coverage, in 2012 the company began offering electricity service to residential and business customers in the PECO and PPL service territories in Pennsylvania.
In 2010 Green Mountain Energy was acquired by major wholesale power player NRG Energy for $350 million. The acquisition expanded the parent company's renewable energy portfolio and grew its footprint in the Texas market. It also gave Green Mountain Energy access to the deep pockets of its parent to help expand its renewable energy activities.
