STEP 1) Apply for your Temporary Meter Loop permit with your city or municipality, such as the City of San Antonio.

STEP 2) Construct your Temporary Meter Loop in compliance with Temporary Meter Loop Diagram [Underground] diagrams, ensure the structure has clear access, and mark it with the physical address [CPS Energy Addressing Requirements for Meter Installation]. If you need assistance determining where to put your temporary loop, call us at 210-353-4050.

CPS Energy typically digs trenches and installs conduit for residential customers. However, residential customers have the option to install their own trenches and conduits in accordance with the Trench diagram in the Site Ready document. Residential customers need to notify their CPS Energy representative if they plan to install their own trench by calling Customer Engineering at 210-353-4050.
CPS Energy provides job sketch with meter location(s) and an invoice for CPS Energy work.
CPS Energy will typically process your Permanent Service application within two business days and email you a Job Sketch with the meter location on your site. We may need to perform a Utility Survey Inspection to determine the meter location. If CPS Energy will be digging a trench, we will visit your site to obtain measurements needed to calculate your invoice. Please prepare your site and call us at 210-353-4050 and we can do this the following day.
Once we gather all necessary information, we will send an invoice for the cost of the work to be performed by CPS Energy.
Pay your invoice for CPS Energy work.

Apply for the necessary permit(s) with your city or municipality.
You will need to obtain all relevant permits and, where required, final electrical and/or gas inspection(s) from your local city or municipality, such as the City of San Antonio. For more information about City of San Antonio permitting and inspections, go to City of San Antonio - Permit, Inspection and Review. CPS Energy has worked with the City of San Antonio to create a Permits and Inspections Checklist for your assistance. If you are outsides San Antonio, contact your local municipality.
PLEASE NOTE: An electric and/or gas permit is required to construct your Meter Loop and CPS Energy will need a copy of your permit, and later your city/municipality inspection, in order to turn on your permanent service.
Perform all required work and prepare your site for inspections.
Follow the steps to prepare your site for inspection:
- Install all equipment in compliance with CPS Energy Service Standards - Site Ready [Underground Service].
- If you are digging your own trench, ensure it complies with Trench Design section of the document.
- Ensure the grade along the underground service route is within 6 inches of final grade.
- Securely mount electric meter loop and meter can on the structure’s wall and mark it with the physical address. [CPS Energy Addressing Requirements for Meter Installation]
- Install all gas equipment in compliance with Gas Meter Clearance Diagram.
- Stub gas structure pipe out 26 inches above final grade.
- If you are installing gas service, ensure your home interior lines and appliances are ready for either your city’s Gas Inspection or CPS Energy’s Gas Rough-in Inspection, depending on your location.
- To reduce delays on your gas service request, please see these helpful documents to prepare for your inspection.
In addition to infrastructure preparation, ensure that you:
- Clear the service location of all water and drain lines, and underground facilities; including septic systems, culverts, irrigation systems, underground wiring, and other impediments.
- Clear all obstructions and/or debris from cable, gas, transformer, secondary enclosure, and meter location route.
- Sign and return any required easements to CPS Energy.
Request your inspections.
CPS Energy Inspections
Let CPS Energy know that your site is ready by logging on to the Construction & Renovation Web Portal and completing your Site Ready Task. If you are outside the City of San Antonio, request your Gas Rough-in inspection from CPS Energy, which will ensure you are ready to have gas turned on after installation. Read More Here
You can also call CPS Energy at 210-353-4050 to let us know your site is ready.
City or Municipality Inspections
To turn on your service after our infrastructure and meter installation, we require your city or municipality’s successful electric and/or gas inspection(s). We recommend you acquire these inspections as soon as possible. CPS Energy will still install your infrastructure and meters, but in a locked position until we receive the appropriate inspections. In some locations, the CPS Energy Meter Installer will perform this inspection.
CPS Energy and your city or municipality will perform their required inspections.
CPS Energy will perform our required inspection and if your inspection passes, we will schedule your infrastructure install and meter set within 15 business days. If your site fails CPS Energy inspection, you will be notified by email with reason of turndown. Once any issues are corrected, you can re-click site ready in the Construction & Renovation Web Portal or call 210-353-4050 to schedule another Site-Ready inspection.
Your municipality will perform their inspection which are required before CPS can turn on your service.
Note: If there are 3 site ready failed inspections, the site ready button will no longer be available and a message will display for you to call 210-353-4050.
Sign your easements.
If necessary, submit easement documentation for the necessary utilities after they are constructed. The easement or field notes will need to be received, reviewed and signed by the property owner prior to your service being activated. This process can take up to 3 weeks. If an Easement is required for your project, review the information below or click here to Read More.
The owner will need to provide an easement description to the CPS Energy Agent (“Agent”). All Residential Development, Small Commercial, and Large Commercial Projects will require a surveyed easement description. The Agent will determine if a surveyed easement description is necessary for Residential Service projects.
If your project requires a third-party easement, please contact the Agent. The third-party easement must be secured and finalized early in the project.
CPS Energy installs your underground infrastructure and meter(s) then turns on your service(s).
PLEASE NOTE: To avoid delays, please ensure CPS Energy can access your property to perform their work.
CPS Energy will dig your trench, install conduit, and backfill. Once underground service infrastructure is in place, and if CPS Energy has already received your electric and/or gas permit inspections, CPS Energy will set your meter(s) and activate your service(s).
- If electric permit inspections are required and not received by CPS Energy, the electric meter will be set and locked until we receive your permit inspections. Once received, CPS Energy will schedule a meter crew to activate your service.
- If gas permit inspections are required and not received, CPS Energy cannot set your gas meter. Once we receive you gas permit inspections, CPS Energy will schedule a meter crew to install your gas meter and activate your service.
