This guide is a resource for understanding and comparing green electricity providers in Texas for 2026. The analysis evaluates companies on three primary criteria: the percentage of renewable energy in their plans, the clarity of their pricing as detailed in the Electricity Facts Label (EFL), and publicly available customer service data. Texas’s deregulated electricity market allows the majority of residents to choose their Retail Electric Provider (REP), creating a competitive landscape where consumers can select plans that align with their environmental and financial priorities. This choice is increasingly significant given the substantial growth of renewables in the state's energy portfolio.

The state's grid, managed by the Electric Reliability Council of Texas (ERCOT), has seen a profound shift toward sustainable sources. In 2024, the combination of wind and solar power accounted for 30% of power generation, a marked increase from 18% in 2019. This growth positions Texas as a national leader in renewable generation, having produced 169,442 gigawatt-hours from wind and solar in 2024, far outpacing other states. As of Q3 of 2025, data confirmed that renewable sources accounted for 36% of the electricity on the ERCOT grid, demonstrating a sustained trend toward cleaner energy production that directly impacts consumer options.

Comparative Analysis of Texas Green Energy Providers

The following table offers a high-level comparison of providers based on core metrics. This allows consumers to quickly assess key features before reading the detailed profiles that follow. The metrics focus on renewable energy sourcing commitments, representative plan types, and the basis for evaluating customer service.

2026 Provider Profiles

This section provides detailed, factual information on individual providers that offer robust renewable energy plans. The profiles focus on plan structures, renewable sourcing policies, and other distinguishing features relevant to consumers in 2026.

Rhythm Energy

Rhythm Energy is a Texas-based provider that sources 100% of the electricity for its plans from renewable resources, including Texas wind and solar, making it a distinct choice in the market for Texas electricity. The company offers several distinct plan structures designed to cater to different consumer usage patterns. Their Simple Fixed Rate plans provide price certainty over a contract term, while their PowerShift Time-of-Use plans are structured to offer lower rates during off-peak hours, incentivizing customers to shift high-consumption activities like EV charging or running major appliances to times of lower grid demand.

For homeowners with solar panels, Rhythm Energy provides a Solar Buyback plan that purchases excess electricity generated on-site. The company also promotes a 30-Day Test Drive policy, allowing new customers to switch plans or leave without an early termination fee within the first month. This policy, along with their focus on Texas-generated renewable energy, is a central component of their customer acquisition strategy. Pricing and plan details are available on the company’s website or the state-mandated Electricity Facts Label (EFL) for each specific offer.

Gexa Energy

Gexa Energy commits to providing 100% green energy plans for all its residential customers, making it a straightforward choice for environmentally conscious consumers. The company’s most common plan structure involves fixed-rate contracts, often featuring tiered pricing or usage credits. These credits can significantly reduce bills for customers whose monthly consumption falls within specific kilowatt-hour (kWh) ranges, rewarding predictable energy usage. Gexa Energy is a subsidiary of NextEra Energy Resources, one of the largest generators of wind and solar power in North America, which provides a strong foundation for its renewable energy supply.

Green Mountain Energy

Positioned as one of the original green energy providers in the Texas market, Green Mountain Energy was founded with a mission-driven focus on sustainability that continues to define its brand. The company exclusively offers plans sourced from 100% renewable energy. Customers can choose plans sourced specifically from 100% Texas wind or from a blend of solar and wind resources, allowing for a greater degree of control over the origin of their power. Its long-term presence and specialization in the renewable sector serve as distinguishing factors in a crowded marketplace.

TXU Energy

As one of the largest and most established retail electricity providers in Texas, TXU Energy serves a broad customer base with a diverse array of plans. While not all of its offerings are renewable, the company provides specific, clearly marketed green energy options to meet growing consumer demand. A notable example is its Solar Days plan, which provides electricity at a $0 energy charge during daytime hours when solar production on the grid is highest (typically from 9 a.m. to 6 p.m.). This plan structure positions TXU Energy as a legacy provider that is actively adapting its products to the new realities of a renewable-heavy grid.

A Framework for Choosing a Provider

Beyond evaluating the providers themselves, consumers should understand the fundamental structure of energy plans and the broader context of the Texas grid. A thorough review of plan documents and an awareness of grid dynamics are essential for making an informed decision that aligns with both budgetary and environmental goals.

Deciphering the Electricity Facts Label (EFL)

The Electricity Facts Label (EFL) is a standardized document required by the Public Utility Commission of Texas for every plan offered. It is the single most critical tool for ensuring price transparency. The EFL breaks down the exact cost components, including the price per kWh, any monthly base charges, and delivery fees from the local utility (TDU charges). Crucially, it provides an average price at three standard consumption levels—500, 1000, and 2000 kWh—allowing for a direct comparison between offers. Consumers must review the EFL for any prospective plan to understand the true cost and avoid unexpected charges.

Types of Green Energy Plans

• Fixed-Rate Plans: Your energy rate (price per kWh) is locked in for the duration of your contract (e.g., 12, 24, or 36 months). This provides budget certainty and protection from market price volatility.

• Variable-Rate Plans: The energy rate can change monthly based on market conditions. While this can sometimes result in lower prices, it also exposes the consumer to potential price spikes.

• Time-of-Use (TOU) Plans: These plans offer different energy rates at different times of the day or on weekends. They are designed to reward customers who can shift their heavy electricity usage to off-peak hours when demand on the grid is lower.

• Solar Buyback Plans: For homes with solar panels, these plans credit the customer for excess energy sent back to the grid. The credit structure (e.g., real-time market rate vs. a fixed credit) varies significantly between providers.

Renewable Energy and Texas Grid Stability in 2026

The rapid expansion of renewable energy sources has fundamentally changed the operation and stability of the Texas grid. Since the February 2021 winter storm, state regulators and grid operators have implemented significant changes to strengthen infrastructure. These efforts include improved weatherization standards and, critically, the addition of new generation capacity, with approximately 90% of new generation added to the grid coming from solar, wind, and batteries. The U.S. Energy Information Administration (EIA) projects this trend will accelerate, with solar energy supplied to the ERCOT grid expected to grow from 56 billion kWh in 2025 to a projected 106 billion kWh in 2027.

To manage the intermittent nature of wind and solar, battery storage systems have become increasingly critical. These systems store excess energy generated during sunny or windy periods and dispatch it when those sources are unavailable, such as at night or on calm, cloudy days, thereby enhancing grid reliability. News reports confirm that these battery storage systems are essential for maintaining power if freezing precipitation affects wind turbines. Simultaneously, the grid faces rising demand from new, large-scale consumers like data centers and AI facilities. This increased load places additional pressure on the grid, making both new generation and sophisticated demand management crucial for maintaining a stable power supply, a challenge ERCOT is addressing via a new planning process designed to manage large grid-connection projects.
