- Net Excess Generation Notes
- NEM 2.0 program is billed in real-time, meaning your electric usage and solar generation is tracked on an hourly (residential customers) or 15-minute (commercial customers) basis.
- Any time you are pulling energy from MID's grid you will be charged MID's retail rate.
- If your solar is over-generating and pushing energy back to MID's grid, you will be compensated at 7.6 cents per kWh.
- These excess generation credits will show on your monthly MID bill as a negative amount to bring the overall bill down.

- System Offset Notes
- Systems can produce 115% of the customer's current 12-month usage
- If the customer does not have 12 months of usage, then they must have a minimum of 6 months usage, and we will use the average (no additional 15% will be granted).
- If the customer does not have the minimum 6 months usage, then it is based off industry standard of 2/watts per square foot of the home (no additional 15% will be granted).
- For solar addition projects, the customer will need to have a minimum of 6 months solar generation history before we can consider a panel addition project.
