Hello,
SAM downloads utility rate data from the
NREL OpenEI utility rate database
. The database may have errors or out-of-date data. If you create an account on the OpenEI website, you can correct errors that you find by editing the database.
In general, when you use one of the data download features in SAM (utility rates, incentives, weather data, etc.), we recommend that you review the data you downloaded to make sure it is correct, and make any changes necessary to correct errors in SAM. We provide the download features as a convenience, but do not have control over the accuracy of the data in the databases that SAM communicates with.
Best regards,
Paul.
