We began in Vermont in 1997 with a simple but powerful mission: Use the power of consumer choice to change the way power is made. Today, we’re still 100% dedicated to protecting the environment, and we invite you to join us.

Our Business Structure

We sell cleaner electricity to both residential (home/condo/apartment) and commercial (business) customers.

Residential Products

We serve households in competitive markets in Illinois, Maryland, New York, Pennsylvania and Texas.

In traditional monopoly utility markets, Green Mountain partners with utilities who want to offer renewable energy products to their customers.

Outside of these areas, Green Mountain offers renewable energy certificates (RECs) and carbon offset products to help reduce the environmental impact of everyday activities like electricity use, driving and flying.

Commercial Products

Green Mountain is one of the premier retail providers of cost-competitive cleaner energy products to businesses and institutions in competitive electricity markets in Illinois, New Jersey, New York, Pennsylvania and Texas.

Nationwide, we offer innovative, customized sustainability solutions to commercial clients, including carbon offsets and RECs as well as consulting and assistance with green marketing strategy, corporate sustainability reporting and voluntary emissions reporting.
