Fees
| Fee | Applies to | Note |
|---|---|---|
| $100 | All Schedule 68 applications < 3 MVA, incl. modifications | Non-refundable |
| $1,000 deposit | Feasibility Study if required |
Utility fees are paid by the installer or customer; they are not part of the Gridpol plan.
Size levels and limits
| Level | Up to | Note |
|---|---|---|
| Residential/small general (Sch 1/7 -> Sch 6/8) | 25 kW | AC nameplate |
| Large general/large power/irrigation (Sch 84) | 100 kW | Greater of 100 kW or max monthly billing demand in last 12 months |

Battery storage
Storage allowed (stand-alone storage only as non-exporting). Storage does not count toward schedule size limits; DC-coupled sized by inverter kVA, AC-coupled storage adds to total nameplate for Feasibility Review.
Common issues the utility lists
- Incomplete application not cured within 60 days is withdrawn
- Breaker used instead of required AC disconnect switch
- Installed components not matching application/System Verification Form
Gridpol’s pre-submission check covers these before we file.
