Constellation Electricity Plans and Rates in Texas

Constellation Overview

Constellation is one of the largest and most institutionally significant retail electricity providers operating in Texas. Headquartered in Baltimore, Maryland, and publicly traded on Nasdaq under the ticker CEG (a component of both the Nasdaq-100 and S&P 500), Constellation Energy Corporation operates as the successor to a company with roots going back to 1999, most recently spun off from Exelon in 2022. The company holds PUCT REP Certificate Number 10014 in Texas and Power to Choose rating of 4 of 5, serving customers across 6 of Texas's deregulated TDU territories: CenterPoint, Oncor, AEP Texas Central, AEP Texas North, TNMP, and Lubbock Power & Light.

Constellation's scale is genuinely different from most Texas REPs. Corporate operations reach approximately 2 million customers across the continental United States, with $25.5 billion in 2025 revenue, $57.2 billion in total assets, and more than 15,000 employees. Constellation also owns and operates a large fleet of power generation assets, including the Calvert Cliffs Nuclear Power Plant in Maryland and natural gas combined-cycle generation facilities in Texas (Colorado Bend Energy Center in Wharton and Quail Run Energy Center near Odessa, jointly adding 1,100 MW of Texas generation capacity). This vertical integration between generation and retail is unusual and gives Constellation structural advantages that pure-retail REPs cannot match.

For Texas customers, Constellation offers a straightforward fixed-rate retail electricity catalog spanning 15 plans across contract terms from 3 months to 36 months. 1 plans are 100% renewable (7% of the catalog). The lowest current rate is 10.6¢ per kWh at 1,000 kWh usage, and the catalog-wide average is 12.5¢. Beyond retail electricity, Constellation is a major provider of natural gas and energy management services in markets that allow both products.

Constellation is not available to businesses or residents in Austin (served by Austin Energy) or San Antonio (served by CPS Energy), since both cities operate under municipal utilities that fall outside the deregulated retail market. Coverage also does not extend to Nueces Electric Cooperative.

Constellation Electricity Plans

Constellation currently offers 15 electricity plans across 6 Texas TDU territories, with contract terms ranging from 3 months to 36 months. 1 plans are 100% renewable (7% of the total catalog). The lowest current rate is 10.6¢ per kWh at 1,000 kWh usage, and the catalog-wide average is 12.5¢. Rates update with market conditions and were last refreshed on September 15, 2026, so pricing below is indicative and should be confirmed on the Electricity Facts Label (EFL) at the time of enrollment.

Constellation's residential catalog is built around straightforward fixed-rate plans, keeping product selection relatively simple. Fixed-rate contracts lock the energy charge for the length of the term, giving customers predictable billing without exposure to variable-rate market swings. Terms are commonly available in 12, 24, and 36-month options, letting customers match their contract length to their preferred commitment level.

Renewable-energy versions are available across most of the plan structures, giving customers who prioritize sustainability the option to select 100% renewable content without changing plan structure. Constellation's parent-company relationship with a large fleet of nuclear generation is worth noting for sustainability-focused customers: nuclear power is carbon-free but not classified as renewable, so customers should confirm the specific renewable content composition on the EFL if that distinction matters.

For commercial customers, Constellation offers materially more sophisticated product options than the residential catalog. As one of the largest US commercial and industrial electricity providers, Constellation supports customers with complex load profiles, multi-site operations across multiple deregulated states, and specific energy management needs including index-based pricing, hybrid structures, and layered procurement strategies. The company's parent-level generation assets and market operations infrastructure give commercial customers access to more sophisticated procurement and risk management tools than most Texas REPs can offer.

Below, Constellation's plans are organized by TDU zone.

About Constellation

Constellation Energy Corporation is the current iteration of a company with a long institutional history. The original Constellation Energy was created in 1999 as a holding company by Baltimore Gas and Electric, and grew into one of the largest electricity producers in the United States operating more than 35 power plants across 11 states. In 2012, Constellation Energy Group merged with Exelon, becoming Exelon's competitive energy retail arm operating under the Constellation brand. In 2022, Constellation Energy Corporation was spun off from Exelon as a standalone publicly-traded company, becoming the entity that operates today.

The company is now one of the largest independent power producers in the United States, with a substantial nuclear generation fleet (including the Calvert Cliffs Nuclear Power Plant in Maryland) plus natural gas, wind, and solar assets. In Texas, Constellation owns and operates two natural gas combined-cycle generation facilities: Colorado Bend Energy Center (550 MW near Wharton) and Quail Run Energy Center (550 MW near Odessa). This vertical integration between generation and retail is genuinely differentiating: most retail REPs purchase electricity from wholesale markets and resell it, but Constellation generates a substantial portion of its retail supply from assets it owns and operates.

Leadership is anchored by President and CEO Joseph Dominguez, who has led the company through its post-spinoff independence. Corporate headquarters remain in Baltimore, Maryland, with substantial operations across the states where Constellation operates.

For retail electricity customers, Constellation's product positioning centers on stability and scale. Fixed-rate plans dominate the residential catalog, with straightforward terms that avoid the promotional structures and usage-tier gimmicks that dominate some competing REPs. The company's Fortune 500-level scale means it operates with resources for customer service, billing infrastructure, and regulatory compliance that smaller Texas REPs cannot match. That scale can be an advantage for customers who value institutional stability, or it can feel less personal than working with a smaller Texas-focused provider.

Cancellation Fees and Non-Recurring Charges

Cancellation fees on Constellation's fixed-rate plans scale with contract length, running from $50 to $150. Longer contract terms carry higher cancellation fees, reflecting the longer commitment period.

Beyond early termination, Constellation's terms of service also cover non-recurring charges that apply in specific situations: late payment charges, returned payment or insufficient funds fees, disconnection notice fees, disconnection-plus-reconnection fees, and any non-AutoPay billing fees. These are not published on Power to Choose and are only disclosed in the provider's terms of service and EFL documents.

For commercial customers using more sophisticated procurement structures (index-based, hybrid, or layered purchase plans), cancellation and settlement terms are structured differently from standard fixed-rate plans. Mark-to-market settlement provisions can result in higher or lower termination costs depending on where wholesale market pricing has moved during the contract. Electric Decisions can help commercial customers evaluate the risk implications of these structures before signing.

Constellation Pros and Cons

Pros:

• Massive corporate scale and stability: With $25.5 billion in 2025 revenue and 15,000-plus employees, Constellation operates at Fortune 500 scale that most Texas REPs cannot match.
• Vertical integration between generation and retail: Constellation owns significant generation assets in Texas and nationally, including nuclear, natural gas, wind, and solar. This vertical integration provides structural supply advantages.
• Publicly traded transparency: As a Nasdaq-listed public company (CEG), Constellation publishes extensive corporate financial and operational data, providing transparency that private REPs cannot match.
• Multi-state operational footprint: Approximately 2 million customers across the continental US provide operational experience and infrastructure that Texas-only REPs cannot match.
• Sophisticated commercial procurement options: Beyond standard fixed-rate residential plans, Constellation offers advanced commercial procurement structures including index-based, hybrid, and layered purchase plans.
• Long institutional history: Corporate roots back to 1999 provide substantial market experience through multiple industry cycles.
• Nuclear and renewable generation portfolio: The company's substantial nuclear generation fleet provides carbon-free electricity, with additional renewable assets in wind and solar.
• Straightforward residential product mix: Fixed-rate plans without heavy reliance on bill-credit or usage-tier structures make plan selection relatively simple.

Cons:

• Less Texas-specific focus: As a national provider headquartered in Baltimore, Constellation's Texas operations are one part of a much broader corporate portfolio, which may feel less locally-focused than Texas-specific REPs.
• Cancellation fees on longer terms: The 36-month ETF at the high end of the $50 to $150 range runs comparable to or above what some competing Texas REPs charge for equivalent terms.
• Corporate customer service model: Fortune 500 customer service infrastructure can feel less personal than smaller Texas-focused REPs, though it typically carries more resources.
• Nuclear generation portfolio may not fit all sustainability preferences: While nuclear is carbon-free, it is not classified as renewable, so sustainability-focused customers should confirm renewable content specifically on the EFL for their chosen plan.
• Rate competitiveness varies by market: Advertised rates in some TDU zones run competitive with market averages, while in others they run at the higher end.
• Limited product structure variety at residential level: Fixed-rate plans dominate the residential offering. Customers seeking Free Nights, Free Weekends, or complex promotional structures need to look elsewhere.

Constellation Reviews

Independent customer reviews for Constellation are generally favorable, consistent with the company's scale and Fortune 500 operational infrastructure. Customer feedback tends to emphasize billing reliability, the transparency of the fixed-rate structure, and the responsiveness of customer service. Commercial customer feedback focuses on the sophistication of the procurement options and the operational depth of the account management team. For general customer sentiment, the provider's Google reviews and the official Public Utility Commission of Texas complaint scorecard at puct.texas.gov are the most reliable public references.

Constellation for Residential and Commercial Customers

Constellation sells electricity to both residential and commercial accounts across its TDU service areas, with materially different product offerings for each segment.

For Residential Customers:- If you are a Texas homeowner or renter researching Constellation for your home, sign-up runs through the Constellation website, through Power to Choose, or through third-party enrollment marketplaces. Every published plan carries an Electricity Facts Label showing the exact rate, delivery charges, term length, and cancellation fee for your specific TDU zone.

Constellation's residential catalog is straightforward. Choose the contract term that matches your commitment preferences (12, 24, or 36 months), verify the renewable content level if sustainability matters, and confirm the effective rate at your actual usage level on the EFL. Because Constellation avoids bill-credit and usage-tier structures on residential plans, EFL comparison against competing REPs is direct.

Electric Decisions does not enroll residential accounts. Residential customers can shop Constellation directly through the sources above.

For Commercial Customers:- For Texas businesses, Constellation offers materially more sophisticated options than the residential catalog. As one of the largest US commercial and industrial electricity providers, Constellation supports customers with complex load profiles, multi-site operations across multiple deregulated states, and specific energy management needs. Product structures include:

• Standard fixed-price commercial contracts
• Index-based plans (rate floats with defined market index)
• Hybrid plans (combining fixed and index components)
• Layered purchase plans (spreading procurement over multiple decisions)
• Multi-site consolidated contracts for national customers with operations across multiple deregulated markets

Commercial pricing is not published on Power to Choose and is quoted based on load profile, contract term, TDU zone, and where the ERCOT forward curve is trading at the moment of contract lock. Commercial contracts also carry negotiable terms that materially affect total cost: bandwidth (swing tolerance), early termination fee methodology, add and delete meter language, holdover rate, and pass-through TDSP delivery treatment.

Electric Decisions runs an apples-to-apples RFP process for Constellation alongside every other qualified Texas REP. Bids come in against identical specifications, are benchmarked against the live ERCOT forward curve, and every contract is red-lined in plain English before you sign.
