If, in any month, the customer’s bill has a credit balance of $25 or less, the amount shall be credited to subsequent bills until a debit balance is reestablished. If the credit balance is more than $25, the utility shall reimburse the customer by check upon request. Monthly credits shall be computed by taking the net excess kilowatt-hours produced times the sum of the applicable energy charge plus monthly power cost adjustment clause (PCAC).

System Offset Notes

Oconomowoc Utilities doesn’t have any size restrictions on the size of distributed generation however the purchase of excess generation (energy not used by the owner/customer that is put back into the local distribution network) by Oconomowoc Utilities is determined by the size of the DG installation.

Excess generation by DG installations less than 20 kW in size is purchased according to the Pgs-1 tariff (attached.)

Excess generation by DG installations greater than 20 kW in size is purchased according to the Pgs-2 tariff (attached.)

Meter Spot Process

Any PV installation directly or indirectly connected to the utility distribution network has the potential to send power back on to the grid. The utility is required by the Wisconsin Public Service Commission to purchase any excess generation and so all connected distributed generation is required to be metered according to the WI PSC

There is not a separate PV production meter. A bi-directional meter will be installed by the utility.

Installing a bi-directional meter for grid-connected DG applications is a standard practice.

Allowed Meter Adapter
None

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with Oconomowoc Utilities before you rely on this. The useful move: if an installer says you need a main panel upgrade, ask how these tap and interconnection policies were considered first.
