Electric Utility Design Criteria
Criteria for building and trade professionals
who design or install electric facilities
The Austin Energy Design Criteria Manual provides criteria, guidelines, definitions, and descriptions for the design and installation of electric facilities that will be served by Austin Energy (AE).
You can view and download the online version of the manual for free, or you can purchase a printed version from the One Stop Shop on Barton Springs Road.
We make every effort to be accurate in the online Austin Energy Design Criteria Manual. In case of conflict, the official manual on file with the Austin City Clerk's office takes precedence.

Electrical Service Planning Application (ESPAs)
The Electrical Service Planning Application is needed to obtain a permit and is also used by the design team to determine your power requirements. Print and complete your ESPA, and mail it to the address listed on the top of the application.
View and download the right ESPA for your job:
Austin Energy’s signing of the ESPA signifies that Austin Energy can provide the load, voltage and type of infrastructure requested on the ESPA. Customers are still responsible for providing the necessary infrastructure, and for following all NEC codes and the Austin Energy Design Criteria.
Commercial Electrical Permitting Application
In addition to the ESPA, you may also be required to complete a Commercial Electric Permitting Application (pdf) for multi-metered commercial projects. You will need to include the completed form with the Building Plan Review package.
Contact the appropriate distribution engineering design office (listed above) if you have questions.
