Major utility solar profiles

These pages summarize homeowner-facing solar billing and interconnection rules using current utility sources. They are not utility endorsements and do not replace the controlling tariff.

Find your utility by ZIP

Use the ZIP lookup to find nearby residential tariffs and distributed-generation references from OpenEI. Utility service territories can overlap or differ from city boundaries, so ZIP-level lookup is a better next step than guessing from the city name.

Why utility tariffs matter for solar payback

  • A high retail electricity rate can improve the value of solar energy you consume directly in the home.
  • Time-of-use pricing changes the value of grid imports depending on when electricity is used.
  • Net billing can value exported solar differently from electricity purchased from the grid.
  • Tiered pricing means the marginal kWh price may differ from a simple monthly average.
  • Fixed or base service charges can remain even when solar reduces annual grid energy purchases.
  • Community Choice Aggregation or competitive supply can separate generation pricing from utility delivery charges.

How Home Solar Atlas handles utility data

State-average electricity rates are used only as a planning benchmark. Utility pages separately summarize current official solar and interconnection information, while the ZIP tool provides tariff references. We do not automatically treat a sample tariff rate as your all-in electricity price because TOU periods, tiers, riders, fixed charges and export compensation require a fuller tariff engine.
