Interconnection

If you see this line item on your bill, it’s because you’ve got solar panels, wind turbines, or other small power-generating equipment at your location, and you’ve signed up for Interconnection, which allows you to export the excess energy you generate into our system. At the end of each month, any energy you’ve generated and put back into the system, subtracted from the energy we sold to you, is called net energy and will be credited back to you on your monthly bill at the Base Power Cost.
