Utility rate lookup
Average electricity rate (¢/kWh) by zip
Enter a U.S. ZIP code to find the serving utility and its average residential, commercial, and industrial electricity rates. The grid price is the benchmark every on-site solar-plus-storage decision is measured against.
Look up your grid rate
We resolve your postal code to coordinates and query the NREL Utility Rates database for the utility serving that location.
Coverage is U.S. only. Rates are annual average $/kWh by sector from the NREL Utility Rates v3 dataset; your actual tariff (tiers, demand charges, time-of-use) may differ.
Enter a ZIP code to see your utility and its average rates.
