Constellation

Company Overview

Here’s the truth about Constellation: They’re one of the few electricity companies that actually generates power instead of just reselling it.

Most Texas REPs—including TXU and Reliant—are essentially middlemen. They buy electricity wholesale and sell it to you retail. Constellation owns nuclear plants, wind farms, and solar installations. When they sell you “clean energy,” it’s backed by facilities they actually operate, not just paper certificates.

The catch? You’re paying premium prices. Constellation is 15-25% above budget providers. Like TXU and Reliant, they’re selling brand comfort and corporate stability—except their brand includes actual power generation infrastructure.

Worth about $70 billion and publicly traded (NASDAQ: CEG), Constellation isn’t going anywhere. But if you’re just looking for cheap electricity and don’t care about carbon-free sourcing, you’re paying extra for something that won’t affect your monthly bill.

Where Constellation Operates

Constellation serves deregulated areas across Texas, including Houston, Dallas-Fort Worth, and regions covered by Oncor, CenterPoint, AEP Texas, and TNMP.

Plan Types Offered

Fixed-Rate Plans Straightforward fixed-rate plans with terms from 12 to 36 months. Constellation focuses on simple plan structures rather than promotional complexity.

Variable-Rate Plans Month-to-month options for customers who prefer flexibility over rate certainty.

Green Energy Plans Constellation’s standout offering is their carbon-free energy portfolio. They offer:

• 100% renewable plans (wind and solar)
• Plans backed by their nuclear fleet (carbon-free but not renewable)
• Blended clean energy options

The Carbon-Free Difference

Here’s what separates Constellation from “green” pretenders:

They own the power plants. When you buy clean energy from Constellation, it’s backed by nuclear reactors, wind farms, and solar installations they actually operate. Not just certificates.

Nuclear is carbon-free. It’s not “renewable” in the traditional sense, but it produces zero carbon emissions. Constellation’s nuclear fleet generates more carbon-free power than any other US company.

The catch: Nuclear has its own issues (waste storage, meltdown risk, however small). If you only want wind and solar, specify that when you sign up.

Deposit Requirements

Constellation uses standard credit-based deposit requirements. Good credit typically means no deposit. Others may need to provide a deposit or documentation of prior payment history.

Customer Service: The Real Story

Constellation focuses on clean energy credibility, not customer service bells and whistles.

Worth knowing:

• Simple, no-games plan structures—what you see is what you pay
• Strong business customer support (that’s their real focus)
• Clean energy sourcing they can actually document

The catch:

• Residential customers aren’t their priority—businesses are
• Premium pricing with no budget options
• No prepaid, no free nights, no specialty plans
• Baltimore headquarters means they’re not deeply Texas-focused

Complaint Statistics

PUCT data shows Constellation gets few complaints—but they also have a smaller Texas customer base than TXU or Reliant. Per-customer complaint rate is favorable, but sample size is smaller.

Constellation works for environmentally-conscious customers and businesses who need documented clean energy sourcing. If you just want cheap electricity, look elsewhere.
