About Green Mountain Energy

Green Mountain Energy is a Houston-based electricity provider founded in 1997. It specializes in clean energy for residential and commercial electricity customers. Green Mountain Energy was the first energy company in Texas that focused solely on green energy through wind and solar initiatives. 

It’s not unusual that a Texas-based company would be a strong green energy option. Texas leads the nation in electricity generated by wind, and it ranks within the top 5 states monthly for electricity generated by solar means.

Outside Texas, Green Mountain Energy provides green energy in Illinois, Massachusetts, Pennsylvania, among other states.

Frequently asked questions about Green Mountain Energy

What makes Green Mountain Energy unique?

Green Mountain Energy is based in Austin, part of the NRG family of brands. All Green Mountain Energy plans are fully backed by renewable energy.

Is a renewable energy plan right for me?

For customers who care about the future, renewable energy is a great decision. Green energy sources such as wind and solar have a far lower carbon impact than fossil fuels. A Green Mountain Energy plan allows you to go green without the expense of installing solar panels on your home.

How does Green Mountain Energy compare to other electricity providers?

Green Mountain Energy owns one of the highest ratings on the scale. While other providers may sometimes offer lower rates, you can trust that Green Mountain plans are straightforward with no gimmicks that will make problems during your contract.

What is the cheapest Green Mountain Energy plan?

In general, the longer plan terms offer the cheapest electricity rates. Green Mountain offers plans of up to three years. There also could be savings by opting for variable-rate plans, where rates are fluid from month-to-month with ties to the wholesale energy market. But those rates are subject to increases.
