The contract term lengths of Green Mountain electricity plans usually range from partial year to 12, 24 and 36 months.
Green Mountain may not often be the cheapest electric company or always have the best electricity rates in Texas, but it is a highly trusted brand as part of the NRG family of light companies. Green Mountain energy rates are competitive with major electric companies such as TXU and Direct Energy in all areas of Texas, which are two of the largest power companies.

Renewable Energy (Green Energy) Plans
In Texas, Green Mountain power is available from solar and wind energy sources. By going green with a renewable energy plan, you do not need to install expensive solar panels on your home. Solar panels at utility-scale solar farms absorb sunlight with their photovoltaic cells and use inverter technology to convert this to a usable alternating current, which is delivered to the electric grid and then to homes. Wind power is generated using wind turbines. Large blades turn a rotor when propelled by the wind; the rotor connects to a main shaft which spins a generator, creating electricity, which is delivered to the Texas electricity grid.
You can help cut carbon emissions by enrolling in a green energy plan, or by using our guide to reduce your home’s energy usage and save money in doing so. You can cut your electricity bill while going green with competitive green energy rates on Home Energy Club.

If you’re interested in lowering your Texas energy bill, the information on your bill can give you a good place to start. Evaluating your usage, you may realize key areas where you’re overspending. For example, if you notice seasonal spikes, you might consider installing a smart thermostat and a more energy efficient HVAC system so you can heat and cool your home more efficiently. Upgrades, like better insulation and door and window sealing, will reduce your energy usage as well.
Promo codes can cut your energy rate, and thus your electricity bill, with little effort when you enroll in a plan. Take a look at our promo codes page to see if a Green Mountain Energy promo code is available.
If your bills get higher as the seasons change, you may want to reconsider how you’re using your lights. Switch to more efficient LED bulbs. Connect your bulbs or their associated outlets to smart apps that let you control them remotely, so you can check and make sure all the lights are off even as you lay in bed. Small changes like these can translate to noticeable energy savings.
