- Oncor offers no credit for excess solar generation exported to the grid. Customers must sign up with a third party supplier who offers a buyback credit.
- Net Excess Generation Notes
- For customers who utilize Oncor as their energy supplier, Oncor does not offer a solar buyback program (i,e. net metering or an export rate) and thereby does not give any credit for excess solar generation exported to the grid.
- It is the customer's responsibility to sign up with a retail energy provider who offers a buyback program. Customers are strongly encouraged to maximize the value of their solar system by doing this.
