Oncor & Texas Electric Market
Texas's deregulated electricity market means you choose your retail electricity provider (REP), while Oncor handles the wires and interconnection.
How It Works
- Oncor: Utility that maintains wires and meters
- REP: Your chosen retail electricity provider
- Interconnection: Through Oncor for net metering
- Buyback rates: Vary by retail provider
Choosing a Retail Provider
| Provider Type | Buyback Rate | Consideration |
|---|---|---|
| Solar-friendly REPs | Up to 1:1 retail | Best for high production |
| Standard REPs | Wholesale or less | May not optimize solar |
| Green energy REPs | Varies | Check specific terms |
Texas Grid Considerations
- ERCOT grid: Texas operates its own grid
- Summer peaks: High demand during heat waves
- Battery value: Protection during outages and grid stress
- Net metering: Depends on your REP's program
