How to find your specific utility

1. Check your power bill — the company name on the bill is your utility.
2. Search by zip code: EnergyDeregulation.org or your state PUC website usually has a "find my utility" tool.
3. Call the number on your bill if you're unsure.
4. For solar interconnection: the utility on your bill is the entity you'll apply to for net metering / interconnection.

Why your utility matters for solar

• Net metering rules vary dramatically by utility within the same state.
• Interconnection process and timeline vary by utility.
• Approved equipment lists may differ.
• Capacity caps on residential solar (e.g., 10 kW limit) can vary.
• Demand charges (commercial) structure varies.
• Time-of-use rates with solar-friendly windows differ.
• Cooperatives often have less generous net metering than IOUs.
