Schedule Review and Installation
The Energy Savings team will review your application with the OPALCO Engineering staff and notify you and your installer of approval.
- The Energy Savings team may elect to conduct a pre-installation site inspection. Staff will contact you to schedule as needed.
- Proceed with your installation.
- The OPALCO Engineering team will send you an invoice for a production meter and any other OPALCO related costs (referred to as a “contribution aid of construction”). Please plan to pay this invoice before requesting a final inspection of your installed system.
- After your system is installed and approved by the Washington State Electrical Inspector (Labor & Industries), you or your installer should contact the OPALCO Energy Savings team with your permit number and approval date.
- Submit final site photos to the OPALCO Energy Savings team. A final site inspection may be required. Staff will contact you as needed.
- The OPALCO Engineering team will issue a final approval of your system. The Energy Savings team will notify you of the approval.
- The Energy Savings team will submit a service order for our meter technician to install two meters:
- A bi-directional billing meter to measure power consumed from the grid and power sent to the grid. You will see this meter data on your monthly electric billing statement from OPALCO.
- A production meter to measure all power produced by your renewable system. This measurement is used to calculate any available production incentives. This data does not appear on your monthly billing statement.
See our YouTube video, Understanding Locally Produced Power, for details about Net Metering.
The Energy Savings team will notify you when your meters have been installed.
