Before anything is installed, it's important to go through the interconnection application process.
To connect your devices, like solar panels, battery storage systems, or generators, to the grid, we require you to have a valid tariff option and follow the DER Interconnection Process.
This process isn’t just about meeting utility requirements and state laws, it ensures the safety and reliability of the grid. It’s also an opportunity to uncover any hidden issues and make sure your DER works effectively.
Before committing to any vendor or contractor, we strongly recommend getting an approved interconnection application to understand any necessary upgrades, costs, or mitigations.
Make sure to install DER equipment that is IEEE 1547-2018-certified.
Starting January 1, 2024, make sure you have the right equipment that meets the IEEE 1547-2018 Standard or its equivalent to connect with us. This is important because as more DERs join the grid, they become crucial interconnected components, and we need to trust their reliable performance. For more information, check out the TIIR.
Don't forget to give PSO a heads-up whenever you make changes to your DER.
Before making any major changes to your installation, like adding more solar panels, upgrading or removing your generator, reach out to us. You can send an email to our coordinator at [fill in address] or contact your customer account manager. This is a requirement of your Interconnection Service Agreement, and we're here to help ensure that your changes align with your current grid connection. We'll even give you advice on possible adjustments to support your updated DER.
