Green Mountain Energy vs Chariot Energy: Renewable Providers Compared

Two Green Energy Leaders in Texas

If you want renewable electricity in Texas, Green Mountain Energy and Chariot Energy are two of the most prominent options. Both are committed to clean energy, but they take different approaches to sourcing, plan design, and pricing. For Texans who want to reduce their environmental footprint without overpaying, the choice between these two is worth a closer look.

Renewable Energy Credentials

Green Mountain Energy has been in the renewable energy space since 1997, making it one of the longest-running green electricity providers in the United States. They offer plans powered by a mix of wind and solar energy, with many plans featuring 100% renewable content. Green Mountain sources energy through renewable energy certificates (RECs) and direct power purchase agreements.

Chariot Energy takes a more focused approach, specializing in 100% solar electricity. Their plans are powered by energy from Texas solar farms, and they position themselves as a solar-first provider. Chariot entered the Texas market more recently than Green Mountain but has built a loyal customer base around the simplicity of their solar-focused offering.

Both providers give you a genuinely green alternative to conventional electricity. The renewable energy sources are real, and both providers are transparent about how their clean energy claims are backed.

Plan Types and Pricing

Green Mountain Energy offers a range of plan structures including fixed-rate, variable-rate, and month-to-month options. Some plans include a mix of renewable and conventional energy, while their flagship plans are 100% renewable. Contract terms typically range from month-to-month up to 36 months.

Chariot Energy keeps things simpler. Their plans are generally fixed-rate with 100% solar backing. Contract lengths vary, but Chariot focuses on straightforward pricing with fewer tiers and complications. This simplicity makes it easier to understand exactly what you will pay.

Pricing for both providers has become increasingly competitive as renewable energy costs continue to fall in Texas. Wind and solar generation are abundant in the state, which means green plans are not automatically more expensive than conventional ones. In fact, depending on your ZIP code and consumption level, a green plan from either provider may cost less than a conventional plan from a larger provider.

Coverage Areas

Both Green Mountain Energy and Chariot Energy serve customers across the deregulated areas of Texas. This includes the Oncor (Dallas-Fort Worth), CenterPoint (Houston), AEP Texas (Corpus Christi, surrounding areas), and TNMP territories. Specific plan availability depends on your ZIP code, and each provider may offer different plans in different areas.

Customer Experience

Green Mountain Energy offers a mature digital experience with online account management, consumption monitoring, and customer support by phone, email, and chat. They also invest in community green initiatives and environmental education.

Chariot Energy provides a clean, modern online experience with straightforward account management tools. Their customer service is well regarded, and their simpler plan structure means fewer billing surprises. Chariot also engages in community solar advocacy and environmental programs.

Pros and Cons

Green Mountain Energy brings decades of experience and a wide range of plan options, including some that blend renewable and conventional sources for lower pricing. Their brand recognition is strong. The downside is that plan variety can make it harder to identify the best option without careful comparison.

Chariot Energy offers a clear, simple value proposition: 100% solar electricity with straightforward pricing. This simplicity is an advantage for shoppers who want clean energy without sorting through complex plan structures. The trade-off is fewer plan options overall.
