FOR INSTALLERS

The interconnection application process consists of several steps. Here's an overview for the most common systems with certified equipment.

• Installers or contractors submit an interconnection application through the installer portal.
• Oncor receives and reviews the application.
• Oncor performs an impact assessment of the proposed distributed generation system.
• Oncor prepares an interconnection agreement.
• For smaller systems, the installer forwards the interconnection agreement via the installer portal to the customer for their signature.
• The signed interconnection agreement is processed via the installer portal by the customer or customer's agent and countersigned by Oncor.
• Oncor grants a Permission To Operate (PTO) notification upon receipt of the executed interconnection agreement.
• Meter reprogramming changes are initiated and processed for approved systems (metering for consumption and surplus energy begin).
• Oncor processes profile changes via the Electric Reliability Council of Texas (ERCOT) to enable customers' retail electric provider to account for surplus (kWh) energy sent to the grid.
  

Homeowners and businesses interested in leveraging renewable Distributed Generation (DG) systems should keep a few other things in mind.

• Oncor advanced meters measure energy consumption as well as surplus energy (kWh) that is sent to the grid and eligible for "buy-back." This information is provided to retail electric providers with the first full billing cycle (30-60 days) after the meter set date.
• Customers are responsible for negotiating an agreement with a Retail Electric Provider (REP) of their choice regarding surplus energy produced by their DG system.
• Oncor requires warning placards on all distributed generation projects to alert company employees of a potential alternate source of power. See the Oncor Placard Guideline for more information.
