Now that we have asked these questions, we can identify each of the eight cases, and determine routines that can be followed for each. For simplicity, I have labelled the cases in the following table. They will be covered in the Solutions section of this paper.
| Rate Case | ||
| When Was Solar PV Installed? | Utility Buys and Sells kWh at the Same Rate | Utility Buys and Sells kWh at Different Rates |
| Before the ESP | Case 1 | Case 5 |
| As part of the ESP | Case 2 | Case 6 |
| As part of the ESP, but ESCO does not measure savings due to solar | Case 3 | Case 7 |
| By the client during Performance Period of ESP | Case 4 | Case 8 |
