Power of Community - Pedernales Electric Cooperative

Interconnection Process

We encourage our members to take advantage of solar panel technology, wind energy turbines and other small power-production equipment.

Before installing your generating equipment, please follow the steps below to ensure successful interconnection of all systems:

  1. Comply with PEC Policy
    Review the Co-op's Interconnection Tariff to make sure your system is in compliance.
  2. Sign PEC's Agreement for Interconnection
    Download a copy of the Agreement for Interconnection, review it and upload a signed copy, along with additional documents required below, when you submit your online application for interconnection.
  3. Provide Supporting Documents
    Submit a one-line diagram (example) showing the electrical design of the generating installation, including equipment for interconnection with the Cooperative's system. PEC's Engineering Department may require additional documents. Please attach all supporting documents when submitting the application for interconnection.
  4. Review of Agreement and Supporting Documents
    PEC will review the agreement and supporting documents and notify the member whether permission is granted to proceed with the installation.
  5. Comply with Extension Conditions (if required)
    If extension of PEC's facilities is necessary to complete interconnection, members will be required to comply with conditions of the Line Extension Policy (section 300) in our Tariff and Business Rules for Electric Service.
  6. Comply with Applicable Laws
    It is the member's responsibility to make sure their power generating installations comply with applicable federal, state and local laws, ordinances and regulations.
  7. Complete Construction
    Construct the power generating installation and install a disconnect switch, warning/safety labels, and other protective equipment as may be required by the Cooperative to protect its personnel, facilities and operations. The system may be turned on briefly for testing but must remain off until verified and approved by PEC personnel.
  8. Notify PEC of Completion
    Notify the Cooperative in advance of energizing your small power generating installation and allow PEC staff to verify and test protective equipment. Upon completion of installation, please notify PEC by sending an email to interconnection@peci.com, and for a quicker response please follow the steps below:
    • In the subject line please include the word "Verification."
    • In the body of the email please provide your installation/service address, account number and the name on your PEC account.
    Once PEC receives the notification of completion for the installation, a PEC Energy Service Adviser will contact you to schedule a date and time for a site visit to verify the installation.
  9. Utility Verification
    A representative from PEC will review the system's disconnect and safety features.
    • In the event there are conditions preventing safe interconnection and proper parallel operation, PEC will notify the member.
    • The member may not interconnect or initiate parallel operation until such conditions are corrected and written notification has been provided to PEC at least 10 days in advance of interconnection or parallel operation.
  10. Approval
    After the disconnect and safety features have been reviewed and approved, a PEC representative will sign the Interconnection Agreement and notify the member of approval.

The Cooperative disclaims any expertise or special knowledge related to the design or performance of generating installations and does not warrant the efficiency, cost effectiveness, safety, durability or reliability of generating installations.

In the event the member moves from the location of interconnection, the property owner will need to contact PEC and notify the Co-op of their intent to move from the property.

Please notify PEC when increasing the size of an existing generating facility.
