Casestudies_Empire-StateThe world’s most famous office building was also New York City’s largest commercial purchaser of 100% renewable energy when it became a Green Mountain customer. The Empire State Building had been undergoing a groundbreaking energy efficiency retrofit and chose to purchase 100% clean energy as the next step to further its sustainability efforts.

How We Got Here

January, 2011. As part of its ground-breaking energy efficiency retrofit, the world-famous Empire State Building decided to purchase 100% clean energy to further its sustainability efforts. The iconic landmark contracted with Green Mountain Energy Company to purchase 100% renewable energy, becoming New York City’s largest commercial purchaser of green power.

Green Mountain was selected in a bid process with multiple electric service companies (ESCOs) as a result of its competitive electricity rate, favorable contract terms and leadership in the renewable energy industry. The Empire State Building signed a two-year contract to purchase 100% renewable energy, which was later extended for another 2-year term through 2014.

What It Means

Over the life of its four-year contract with Green Mountain, the Empire State Building is projected to avoid an estimated 239.4 million pounds of CO2. That’s like:

  • Every household in New York State turning off all of its lights for a week and a half
  • Taking every NYC taxi off the road for 6 months

Clean energy and our nearly 40% reduced consumption of watts and BTUs gives us a competitive advantage in attracting the best tenants at the best rents. We were happy to partner with Green Mountain Energy Company on this deal.
