100% Green Plans

They offer straightforward rates (no bill credits), with fixed-rate plans, “free” wind energy nights plans, and solar plans featuring:

Price-protected rates: Almost all of their plans have fixed rates that are locked in until the end of the contract term. Contract lengths usually range from month-to-month to 12, 24, and 36 months.

Pricing: They may not be the cheapest electric company, but their rates are competitive, plus they they’re a highly trusted brand and part of the NRG family of light companies.

City rates: Review Green Mountain Energy Houston rates and Dallas rates, and also the rates for over 100 Texas cities.

Here’s a selection of plans:

Pollution Free All Nighter

Get free energy during set nighttime hours for 12 or 24 months, 7 nights per week, with renewable content listed as 100% wind in the EFL.

Pollution Free e-Plus Term Length

This is a basic straightforward fixed-rate plan usually offered for 12, 24 and 36 months, renewable content listed as 100% wind.

Learn more about the Pollution Free e-Plus 12 plan to determine if it could be a good fit for your energy needs.

Pollution Free e-Plus Month to Month

This is a month-to-month flex plan with a variable rate. This type of plan featuring rates which are not fixed can be useful for certain customers, but be cautious because variable rates are more likely to produce bill surprises. For this reason, we don’t display them. Call an operator for help.

Go Local Solar

Energy for this plan is sourced from Texas solar facilities according to the EFL. It’s a straightforward plan. Ask their operator for available term lengths.

Renewable Rewards

Renewable Energy Credits (RECs)

By purchasing a 100% green plan, you don’t need to install expensive solar panels on your home.

With the enrollment in a Green Mountain electricity plan, you support cleaner energy by matching your annual paid energy usage with an equivalent quantity of power produced by renewable sources of electric generation in the US.

The company purchases and retires renewable energy certificates (RECs) representing the environmental attributes associated with green energy generation for your paid usage. Customers don’t receive power from a specific generation facility under REC programs.

On Home Energy Club, our cost calculator widget helps you to choose an energy plan by performing detailed calculations so you can quickly compare estimated plan costs based on your historic usage data and publicly-available data. Your actual future bill amounts will depend on your future energy usage, which cannot be precisely determined, so the accuracy of plan cost data cannot be guaranteed. You should always read the details of an energy plan’s Electricity Facts Label (EFL) to decide if it’s a fit for your home.

By using the widget, you are certifying that you are the person whose name you have entered into the website and have authorization to access usage data for the address you entered.
