Energy Offerings

For the most part, Green Mountain Energy offers fixed-rate renewable electricity plans. These plans can lock in your contract anywhere from one to three years and are unique in that they support a wide array of renewable options all of which help to reduce your carbon footprint. However, the specific plans Green Mountain Energy offers will differ depending on your state.

Here are some of the common plans available:

  • Footprint Free Plan – Solar energy, offset your carbon emissions and support sustainability projects .
  • Renewable Rewards Buyback Program – a solar buyback program that gives you credit for excess renewable energy produced by your solar system.
  • Local Solar/Wind Plans – Electricity plans sourced from local wind or solar energy plants in your state.
  • Free Nights for EV Owners – Electricity plans with free nights, which are especially beneficial for those with electric vehicles.

Renewable Energy Plans

A renewable electricity plan essentially ensures that no matter how much electricity you use, an equal amount of renewable electricity will go into the grid.

It does not mean that all the electricity you use is now renewable. This is because there's no way to route renewable energy once it enters the electric grid. It gets jumbled up with the rest of the electricity from all other sources.

To keep track of the renewable energy that enters the grid, we use renewable energy credits (RECs). These credits are generated once one full megawatt of renewable electricity enters the grid. The generator can then sell that REC to someone who wants to purchase renewable electricity. When you procure a renewable energy plan, your provider purchases these RECs on your behalf.
