Electric Utility Rates
rates have been contributed for 3,748 EIA-recognized utility companies.
Utility Rate Database Description
The URDB allows you to search for your utility and rates to find out exactly how you are charged for your electric energy usage. Understanding this information can help reduce your bill, for example, by running your appliances during off-peak hours (times during the day when electricity prices are less expensive) and help you make more informed decisions regarding your energy usage.
Rates are also extremely important to the energy analysis community for accurately determining the value and economics of distributed generation such as solar and wind power. The URDB allows anyone to access these rates via bulk download, web interface, or computer-readable Application Programming Interface (API) for use in their tools and models. OpenEI provides an API for software to automatically download the appropriate rates, thereby allowing detailed economic analysis to be done without ever having to directly handle complex rate structures.
NREL’s System Advisor Model or SAM (formerly Solar Advisor Model) has the ability to communicate with the URDB over the internet. SAM can download any rate from the URDB directly into the program, thereby enabling users to conduct detailed studies on various power systems ranging in size from a small residential rooftop solar system to large utility scale installations.

How Can the Utility Rate Database be Used?
Using the System Advisor Model with the URDB enables users to perform economic analyses of energy systems. The Impacts of Utility Rates and Building Type on the Economics of Commercial Photovoltaic Systems evaluates solar value for different rate structures across the United States.
The results of this study can be found at Impact of Utility Rates on PV Economics - Digital Appendix.
