The Big Picture: How Electricity Gets to Your Home

When you flip a light switch in Texas, electricity does not magically appear. It moves through a coordinated system made up of power generators, delivery companies, retail electricity providers, and state regulators. Each has a specific role. Understanding those roles helps you make better decisions about your electricity service.

Texas operates one of the most competitive electricity markets in the country. This structure was designed to give consumers choice, price competition, and innovation, while keeping the grid reliable and regulated.

This guide breaks that system down in simple terms, based on how the Texas electricity market actually operates.

Step 1: Electricity Is Generated

Electricity starts at power generation facilities. These include natural gas plants, wind farms, solar farms, and other generation sources.

Key point for consumers:

• You do not buy electricity directly from a power plant.
• Generation happens behind the scenes and feeds electricity into the Texas grid.

Step 2: ERCOT Keeps the Grid Balanced

The Electric Reliability Council of Texas (ERCOT) manages most of the Texas power grid. ERCOT does not sell electricity. It acts as the traffic controller for power.

ERCOT’s responsibilities include:

• Making sure supply matches demand every moment of the day
• Coordinating power flows across the grid
• Managing the systems that track electricity usage and switching between providers

ERCOT’s role ensures reliability so that when demand spikes, the grid stays online.

Step 3: Transmission and Distribution Companies (TDSPs)

Transmission and Distribution Service Providers, often shortened to TDSPs, are the companies that own and maintain the poles, wires, and meters.

What TDSPs do:

• Deliver electricity to your home or apartment
• Read your electric meter
• Restore power during outages
• Maintain local power infrastructure

Important clarification:

• You cannot choose your TDSP.
• Your TDSP is assigned based on where you live.
• Even if you switch electricity providers, your TDSP stays the same.

This is why outage calls always go to the delivery company, not the company that sends your bill.

Step 4: Retail Electricity Providers Serve You

Retail Electricity Providers are the companies consumers interact with most.

What retail providers do:

• Buy electricity from the wholesale market
• Create electricity plans and pricing options
• Handle customer service and billing
• Pay TDSPs for delivering electricity to your home

This is the part of the market that is competitive. In most of Texas, you can choose your retail electricity provider and your plan.

Plain‑English distinction:

• TDSP delivers power
• Retail provider sells and bills power

They are different roles, even though they work together.

Who Protects Consumers?

The Public Utility Commission of Texas (PUCT) oversees the electricity market.

The PUCT:

• Enforces consumer protection rules
• Sets standards for billing, deposits, and disclosures
• Handles complaints and compliance

Retail providers and TDSPs must follow these rules to operate legally in Texas.

How Switching Electricity Providers Works

When you choose a new electricity provider, the power itself does not change. What changes is:

• Who supplies the electricity financially
• Who bills you

Behind the scenes:

• Your new provider submits an electronic switch request
• ERCOT updates its records
• Your TDSP continues delivering electricity without interruption

No trucks roll. No wires change. Switching is administrative, not physical.

Why Electricity Bills Can Be Confusing

Electricity bills often combine multiple components:

• Energy supply charges
• Delivery charges from the TDSP
• Fees and taxes

Because the market is complex, consumers often struggle to understand:

• Why rates vary so much
• What they are actually paying for
• Whether a plan is competitive

This confusion is one of the biggest pain points in the Texas electricity market.

Where Gatby Fits In

Gatby exists to simplify this system for consumers.

What Gatby does:

• Explains electricity options in clear language

The Takeaway

Texas electricity works because many specialized players do one job well:

• Generators produce power
• ERCOT balances the grid
