Energy efficiency and renewable energy initiatives. Constellation connects power customers with conservation benefits through Efficiency Made Easy, a unique energy efficiency solution. Businesses with sustainability goals or mandates can save money by getting low electricity rates and learn how to reduce energy consumption by including the cost of efficiency projects into their power contracts.

Through the program, Constellation offers:

  • Lighting retrofits
  • Building automation controls
  • Water conservation
  • HVAC upgrades
  • Boiler upgrades
  • Roof repairs and insulation
  • Window upgrades

In addition to the energy efficiency options, Constellation Energy has a number of eco-friendly electricity plans that contain 100% wind energy or a mixture of renewable and non-renewable energy sources.

By enrolling in one of Constellation’s 100% green plans, you can support renewable electricity production in your area, reduce your carbon footprint, and do your part to reduce global climate change and local air pollution.

Businesses can also purchase Renewable Energy Credits (RECs) to offset their carbon emissions and to support the generation of locally-sourced renewable energy, such as wind, solar, hydro, and/or biomass. You can purchase RECs along with your normal power purchase or as a separate transaction.
