New Construction & Development
As a community-owned, public power utility company, KPUB takes great pride in providing our residential and commercial customers with low-cost, reliable and safe electricity.
The information found on this page is designed for those constructing homes or facilities for temporary or permanent service within the KPUB service area.
No matter the size of your residential or commercial project, KPUB is here to provide you with assistance throughout it all in a guiding and supportive manner. If you have any questions throughout this process, please contact our office directly at 830.257.3050 and ask to speak with our engineering department or email us at [email protected].
Additionally, please review our service policy found online here to be familiarized with rules, regulations and the overall process to connect your new service.
Complete an application for electric service and return it to KPUB.
Customers must first make a written application to establish electric service before any necessary facilities are scheduled for construction.
Please note, you must provide us with an accurate service address that is the official 911 designation.
Complete your electric load form and return it to KPUB.
Customers are required to submit a completed electric load form to KPUB that adequately conveys the customer’s electrical service needs. This document is critical for the engineering department to perform calculations to facilitate KPUB providing adequate capacity to the customer. For additional information, please click here to view our service policy.
Failure to complete this will result in a delay in service establishment.
In addition to the load form, KPUB may request additional information such as one-line diagrams, equipment specifications and property survey plats.
Determine if you would like an outdoor light.
If an outdoor light is desired by the customer, please inform our customer service department so that an engineering technician may be advised. A consultation will be set-up upon engineering review. For additional information, please click here to view our service policy.
Please sign the security light agreement, as needed.
Approve your electric design as reviewed with an engineering tech, and pay any fees that may be required (referred to as a Contribution in Aid to Construction, or CIAC).
Contribution In Aid of Construction (CIAC) is the amount owed by the customer to KPUB to establish electrical service.
The CIAC is calculated using a standard construction cost per foot as specified by KPUB’s line extension policy. Any CIAC fees will be determined by engineering and must be paid by the customer before construction activities will be scheduled. For additional information, please click here to view our service policy.
Provide any easement(s) to KPUB for your service project, as required.
The customer requesting service is responsible for the collection of any necessary easements from other property owners to establish electric service. For additional information, please click here to view our service policy.
Ensure the property site is accessible and ready for construction to begin.
Customer shall provide, at no cost to KPUB, suitable space on the customer’s premises, accessible at all times, for the installation and operation of facilities necessary to provide electric service.
Additional clearing may be required to facilitate construction activities beyond the limits of the defined right-of-way. Clearing the property’s right-of-way is the customer’s responsibility and must be done before the job design can be finalized and released for construction activities. For additional information, please click here to view our service policy.
You’re ready to officially connect new service!
Now you can request that your electric service be connected through our engineering department (and please reference your KPUB service order number.)
KPUB Service Policy
Builders and contractors must follow certain specifications when requesting electric service. Before beginning a project, please refer to our service policy for details regarding line extensions, line clearance, easements and more.
For full information on KPUB’s service fees, rules and regulations, please refer to our tariff.
Customers must provide their own meter socket for self-enclosed metering installations. This material can be supplied by an electrical supply house or home improvement store.

Standard Service Voltages
Service is provided with alternating current at a nominal frequency of 60 Hz.
|Single Phase||Three Phase|
As of January 2018, 240/480 Volt three phase service will only be provided for existing services.
All new three phase services must be 277/480 V, 120/208 V, or 7200/12470 V.
The largest overhead transformer size provided is a 75 kVA single phase or 225 kVA three phase. Any Kerrville Public Utility Board Electric Service Policy 2 Effective: March 2019 service requiring capacity above these limits will require a pad mount to be installed.
For all load requests over 400A, three phase service is required. Any three-phase request over 750 kVA will require 480 V secondary service or primary voltage service. Please refer to the Meter Sockets section to determine the appropriate meter socket provided by these requirements.
For standard residential service and in order to meet service entrance fault current ratings, the typical transformer size will be a 100 kVA.
The requirements in our service policy are based upon the applicable provisions of these codes provided below. Customer’s wiring and electrical equipment shall be installed in accordance with the latest editions of these codes. Where municipal, state, or KPUB requirements exceed those stated in these codes, such requirements shall govern.
National Electrical Code (NEC)
The NEC is an American National Standard, published by the National Fire Protection Association, and is used by electrical contractors to install Customer electrical facilities. National Electrical Safety Code (NESC) The NESC is the American National Standard ANSI-C2, published by the Institute for Electrical and Electronics Engineers (IEEE), and is used by KPUB for the design and construction of electric supply facilities.
Clearance from KPUB facilities is governed by the NESC, government agencies, and as outlined in this service policy. The governing clearance from these codes will be the most restrictive as allowed by prudent engineering judgment and as determined at KPUB’s discretion.
Interconnection Requirements for a Distributed Generation System
Distributed generation (DG) refers to small-scale power generation (i.e. solar, wind, other) at a customer’s home, or business, used to reduce the customer’s need for power from the utility power grid.
Click the button below to review the requirements and documentation that must be submitted in order to “interconnect” with the electrical supply provided by KPUB before installing any distributed generation equipment.
