If you are using solar panels and your energy is consistently zero, you may not have to pay Centerpoint Energy delivery charges directly related to energy usage. However, it's important to note that you will likely still have some fixed customer fees, as well as any additional charges related to access to the grid or other services provided by Centerpoint Energy.

It's recommended to contact Centerpoint Energy directly to discuss the specific details of your situation and understand any potential charges or fees that may still apply despite having zero energy usage. Factors such as grid access, maintenance fees, and other regulatory charges may still be applicable.
