Find Your Electric Company by ZIP Code (2026)

The fastest way to find your electric company is by ZIP code. Your address determines which utility delivers your power and which providers are available.

Enter your ZIP at ElectricRates.org to instantly see:
- Your TDU (the utility that delivers your electricity)
- Available REPs (providers you can choose from)
- Current electricity rates in your area

In Texas, two companies serve you:
1. Your TDU (assigned by address — you cannot change this)
2. Your REP (your choice — you can switch anytime)

In Ohio, Pennsylvania, and Massachusetts, the same concept applies: your local utility is fixed, but you choose your electricity supplier. The ElectricRates.org ZIP lookup works for all four states.

Texas has five TDUs in the deregulated market. Your address determines which one.

Not every Texas address has electricity choice. Several major cities operate municipal utilities outside the deregulated market.

Municipal utilities (no REP choice):
- Austin — Austin Energy (city-owned)
- San Antonio — CPS Energy (city-owned)
- El Paso — El Paso Electric (not on ERCOT grid)

Electric cooperatives:
- Rural areas served by member-owned co-ops
- Examples: Pedernales Electric, Bluebonnet Electric
- No provider choice—rates set by co-op board

How to check: Enter your ZIP at ElectricRates.org. If your area is not deregulated, the system will tell you. You can also check the PUCT website for a complete list of deregulated service territories.

About 85% of Texas households have electricity choice. The remaining 15% are in municipal or co-op territories.

Ohio utilities (6):
- AEP Ohio — Columbus area
- Duke Energy Ohio — Cincinnati area
- AES Ohio — Dayton area
- Ohio Edison, Cleveland Illuminating, Toledo Edison — FirstEnergy territories

Pennsylvania utilities (6):
- PECO — Philadelphia
- PPL Electric — Lehigh Valley, Central PA
- Duquesne Light — Pittsburgh
- Met-Ed, PENELEC, West Penn Power — FirstEnergy territories

Massachusetts utilities (3):
- Eversource, National Grid, National Grid Nantucket

Once you know your utility, the next step is comparing electricity rates.

Step 1: Find your current rate. Check your latest bill for the per-kWh charge. In Texas, look at your Electricity Facts Label (EFL) rate at 1,000 kWh.

Step 2: Check your contract status. Are you on a fixed plan, month-to-month, or expired contract? Expired contracts often default to expensive variable rates.

Step 3: Compare available plans. Enter your ZIP at ElectricRates.org to see real-time rates from competing providers. Sort by price, contract length, or renewable content.

Step 4: Switch if you find a better deal. In Texas, switching takes 5 minutes online. In Ohio, Pennsylvania, and Massachusetts, enrollment through ElectricRates.org Smart Enroll is equally fast. Your power stays on during the transition.

People use "electric company" to mean different things. Clarifying the terms prevents confusion.

"Electric company" usually means:
- The company on your bill (your REP in Texas, your supplier in OH/PA/MA)
- The company that fixes outages (your TDU/utility)
- Both — because in regulated states, they are the same entity

In deregulated states, they are different:
- Utility (TDU): Owns wires, fixes outages, reads meters. Assigned by address.
- Provider (REP/supplier): Sets your rate, sends your bill. Your choice.

Why it matters:
- Power outage? Call your utility, not your provider
- High bill? Contact your provider, not your utility
- Moving? Set up service with your provider — they coordinate with the utility

Knowing the difference saves time and frustration, especially during outages or billing disputes.
