Green Mountain Energy Rates, Plans, and Coverage Area

About Green Mountain Energy

Green Mountain Energy has built its reputation around clean, renewable-energy sourcing and putting the environment front and center, while still being a viable choice for everyday household electricity. The company is a retail electric provider based in Texas and operates in deregulated electricity markets (and a few other states) under the belief that customers should have the power to choose their electricity supplier and ask that the power come from renewable sources.

Founded in 1997, they were among the earliest suppliers to focus entirely on renewable energy products. Over time they’ve expanded into multiple states and built a brand around “100% clean electricity” for residential (and also commercial) customers. In short, if you’re looking to align your home energy usage with environmental values, without installing your own solar panels, Green Mountain is one of the mainstream providers making that relatively simple.

Green Mountain Energy Plans and Pricing

*plans and pricing may vary by location. Check your ZIP code to find plans available in your area.

Types of Green Mountain Energy Plans

What sets Green Mountain Energy apart is their commitment to 100% renewable energy. Unlike traditional providers that rely on fossil fuels, they source electricity from wind, solar, and hydroelectric power. Some plans even include Renewable Energy Certificates (RECs), which help fund new renewable energy projects, so you’re not just using clean energy, you’re helping grow the industry!

Green Mountain Energy offers a variety of plan structures to fit different needs and preferences. Here’s what you can expect when shopping for a plan:

• Fixed-Rate Plans lock in your electricity rate for the duration of your contract (typically 12-36 months), protecting you from market fluctuations. They’re a great choice if you want predictable bills and long-term budget stability.
• With Variable-Rate Plans, your rate can change month-to-month based on market conditions. While they offer flexibility (no long-term contract), they’re best for customers who don’t mind some variability in their energy costs.
• Time-of-Use Plans offer different rates depending on the time of day, encouraging you to use energy during off-peak hours when it’s cheaper (or even free, in some cases). If you can shift high-energy activities, like running appliances or charging an EV, to nights or weekends, you could save significantly.
• Solar-Powered Plans are for those who want to support solar energy specifically, some plans source 100% of daytime power from solar farms, with wind or other renewables filling in at night.
• Carbon Offset Plans go beyond electricity, certain plans also offset the carbon emissions from natural gas use in your home, making your entire household footprint greener.

Each plan type has its own benefits, so whether you prioritize price stability, maximum flexibility, or the greenest possible energy mix, there’s likely an option that fits your lifestyle.

Important Plan Details & Fine Print

• Early termination fees (ETFs) apply for many of the fixed-term contracts. For instance, 12-month contracts may carry a $150 ETF, 24-month is $295, and 36-month is $395.
• They offer a “satisfaction guarantee” of sorts, new customers can switch plans within 90 days without paying a fee under certain conditions.
• Checking your local ZIP code is key, because rates and plan availability depend heavily on your utility service area and state.

Green Mountain Energy Coverage Areas

Green Mountain Energy offers its clean-electricity plans in a number of deregulated (or partly deregulated) U.S. markets. Their availability depends on the local utility/retail choice rules and your ZIP code.

Here are some of the major service-areas and cities where Green Mountain plans are available:

• Texas: They operate in many of the deregulated utility territories, including
  • Oncor Electric Delivery (covering Dallas–Fort Worth region)
  • CenterPoint Energy (Houston area)
  • AEP Texas Central / AEP Texas North (areas like Corpus Christi / Abilene)
  • Texas-New Mexico Power (TNMP) in parts of DFW / region.
• Illinois: They serve residential customers under the utility Commonwealth Edison (ComEd) in the Chicago region.
• Massachusetts: Their plans are available in the territories of utilities such as Eversource Energy (NSTAR/WMECo) and National Grid (Mass & Nantucket).
  • Major cities/areas: Greater Boston, the islands (Nantucket) covered by National Grid.
• New York: Available in service territories of utilities like Consolidated Edison (Con Ed NYC & Westchester), Central Hudson, NYSEG, Orange & Rockland, RG&E.
  • Major city: New York City (Manhattan/Brooklyn/Queens) and Westchester county.

Special Case Markets

• Maryland (Changing Market Conditions)
  Maryland technically allows residential energy choice, but new state laws are significantly changing how retail suppliers can operate. These regulations are shifting the market toward stronger oversight, and some suppliers are reducing plan offerings or returning customers to default utility service.
  • Major utilities where plans have been offered: BGE (Baltimore), PEPCO MD (DC suburbs), Potomac Edison (western MD), Delmarva Power (eastern shore)
  • If you’re in Maryland, expect tighter rules, fewer offers, and evolving plan availability.
• Oregon (Commercial Deregulation Only)
  Oregon’s retail choice program is designed primarily for commercial and industrial customers, residential customers do not currently have traditional supplier choice.
  Green Mountain’s presence here is limited and typically connected to partnerships with local utilities such as Portland General Electric (PGE). Residential consumers may see green-energy add-on products, but not the full retail plan menu available in Texas or the Northeast.

Green Mountain Energy Cancellation Fees

If you enroll in a fixed-term plan with Green Mountain and cancel early (before the contract term ends), you will often face an early termination fee (ETF). For example: ~ $150 for a 12-month plan; ~$295 for a 24-month term. The good news is if you move outside their service area, they typically waive the ETF.

They also have a plan-change guarantee, new customers can switch to another plan of theirs within 90 days without paying the ETF (provided certain conditions).

Some of their contract documents also state no ETF for certain month-to-month or variable-rate plans.

Note: It’s always important to read the Electricity Facts Label (EFL) for your specific plan to understand fees, term, base charges, etc.

Green Mountain Mobile App

Green Mountain provides a mobile app (sometimes listed as “Green Mtn” on iOS/Android) that gives you convenient access to your account and energy-use tracking. Some highlights:

• Available to Texas customers (and maybe other regions depending on state) via iOS & Android.
• Features include: bill payment, view balance/history, account services (AutoPay, paperless bills), transfer service if you move, usage tracking with trends & graphs, “green living” rewards and even linking electric-vehicle charging.
• Also provides notifications, impact tracking (e.g., how much CO₂ you’ve avoided), and integration with their sustainability programs.
