Green Mountain Energy plans : Fixed rates

A fixed rate contract offers a price (in ¢/kWh) that does not change from the provider over the whole period of the contract, however the utility energy rate is subject to change. Customers should keep track of when their contract ends, since many retail electric providers in Texas will automatically switch existing customers to variable rates once their fixed contract reaches the end of its term.

Customers report that they appreciate savings on fixed rate electricity plans from Green Mountain Energy. Fixed rate plans can often be a good deal if you are able to lock in a good rate at the right time of year. Electricity prices per kilowatt-hour fluctuate seasonally, and consumers may not be able to take advantage of prices when they are low (this is where timing on a fixed-rate plan can be critical). However, because electricity prices tend to increase over time, locking in fixed rates for longer periods may prove advantageous and prevent overspending.

Green Mountain Energy plans : Variable rates

A variable rate is a rate whose price (in ¢/kWh) changes each month. The variable rate may change at the discretion of the provider (as is the case with Green Mountain Energy variable rates), or as a function of price changes on an energy index.

Zero base fee charges from Green Mountain Energy

None of Green Mountain Energy's plans contains a base charge. Although the utility companies (Oncor, CenterPoint, AEP Texas, and TNMP) charge their own monthly fee - which is passed on to consumers - some electric providers, like TXU and Direct Energy, choose to include this fee into the plans they offer.

Renewable energy plans by Green Mountain Energy

Green Mountain Energy only offers green energy plans. As with most renewable energy plans that providers offer, this plan doesn't promise that your home will be powered using green energy. Instead, the money from bill payments made while on the plan is promised to go towards financially supporting the renewable energy industry.

Check out what is declared in the typical Term Of Service: You will not have electricity from a specific generation facility delivered directly to your service address, but your purchase ensures that renewable energy equal to 100% of your paid electricity usage is produced using renewable resources on an annual basis. The good news is that as renewable energy gains momentum, and investment increases - consumers should anticipate the overall cost of renewable energy plans decrease and household power consumption actually come from green energy sources.
