TXU Energy vs Green Mountain Energy for Renewable Plans

Green Mountain Energy has a more renewable energy focus than TXU Energy. But both have solar power and wind power options.

TXU has several plans that use power from renewable sources. The downside is that they have complex bill credit or time-of-use plans. In our opinion, these plans are not ideal for most people.

On the other hand, Green Mountain has simpler plan terms that still are renewable-focused.

Green Mountain vs TXU Energy for Solar Buy-Back Plans

There are only a handful of electricity providers in Texas that offer solar buyback plans. The terms and buyback rates for these plans fluctuate depending on the market and how much solar power a provider needs to meet their demand.

Make sure you compare up-to-date solar buyback plans before you decide on a plan.

Green Mountain Energy is better known for offering favorable solar buyback plans compared to TXU Energy.

TXU vs Green Mountain for Customer Service

Both Green Mountain Energy and TXU Energy are based in Texas. Green Mountain Energy is headquartered in Houston while TXU Energy is based in Irving.

During normal business hours, you should expect to connect to an on-shore support agent within a couple of minutes. However, when we tested the customer support times of TXU Energy vs Reliant Energy we found that TXU Energy was slightly faster.

Other Texas Energy Providers to Consider

Both Green Mountain Energy and TXU Energy will be able to provide reliable energy service for your home or business. But, don't get stuck on a name brand.

There are dozens of providers in Texas. Neither TXU nor Green Mountain are typically the lowest-priced electricity providers.

So if you are in the Texas electricity market and want to compare the best electricity rates available, we would shop these two brands against the market.
