Net Excess Generation Notes

If the electricity (kilowatt-hours) generated by the Customer-Generator is distributed back to the Utility during the billing period exceeds the electricity (kilowatt-hours) supplied by the Utility, the Customer-Generator: (a) Shall be billed for the basic monthly fee that is consistent within the applicable rate schedule, and (b) Shall be credited for the net excess kilowatt-hours generated, with the credit appearing on the Customer-Generator’s next bill where excess electric (kilowatt-hours) consumption exists where it would be used as an offset by the banked kilowatt hours.


By March 31st of each year any remaining banked kilowatt-hour credit accumulated during the previous year shall be granted to the Utility, without any compensation to the Customer-Generator.

Plans & docs

Site Plan Reqs

If the generation system disconnect is located more than 15 feet from the Utilities net meter, a directory placard must be installed at each equipment location and at the location(s) of the systems disconnect(s). 

This will require a page in the PV Plans that shows the "proposed placard", the placard must MATCH the Site Plan

SLD Reqs

Standard

Electric Service Reqs

AC Disconnect Required:

  • must be UL listed
  • must be accessible to the utility personnel at any time and provide a visible break.
  • Must be located within 15 feet of the net meter
  • If located more than 15 feet away, a locational placard must be installed

Inverter:

  •  UL1741/IEEE1547


25kW or Less:

  • All generating facilities must follow Block 1 processes and technical requirements as follows:
  • Customer’s generation must use inverter-based interconnection equipment which must be certified to meet the requirements of UL1741/IEEE1547;
  • Must use a single phase connection and the equipment has a nameplate rating of 25 kW or less;
  • Proposed service conductor must be connected through a single phase transformer Net Energy Metering Agreement Page 5 9/2020 on a radial distribution circuit;
  • Proposed service conductor must have interconnection at secondary voltages class (600 Volt class);
  • Must not require construction of new or upgrade of existing Utility facilities, other than meter exchanges;
  • Proposed generation service to be interconnected on single-phase shared secondary, will not exceed the load rating of the service wire or the nameplate kVA rating of the transformer;
  • If proposed to be interconnected on a center tap neutral of a 240 volt service, the Customer-Generator will not create a phase imbalance between the two hot legs of the 240 volt single phase service of more than 5 kVA;
  • All interconnected generating facilities must not exceed the Utilities equipment rating. This includes conductor, transformers, and aggregated name plates. Aggregated generation must not exceed 15% of the line sections annual peak load or exceed 15% of connected circuit’s annual peak load that has been recently measured or calculated.
  • A line section is that portion of the Utility’s electric system connected to the generating facility and bound by automatic sectionalizing devices or the end of the distribution line
Placards

Specifications:

  • UV Rated Plastic-Outdoor rated and designed to last ten years and beyond
  • Temperature rating for use between -40F to 176F
  • Engraved
  • Designed to meet NEC 690and NEC 705 requirements
  • 1/16" to 1/8" Thickness
  • Properly installed with strong adhesive backing or rivets holes where applicable

Directory Placards:

If the generation system disconnect is located more than 15 feet from the Utilities net meter, a directory placard must be installed at each equipment location and at the location(s) of the systems disconnect(s). The layout must match the site plan submitted and approved by the Utility during the application process. The placards must provide information as to where the array is located for first responders and to show the location of any load centers or other disconnection devices.


All other NEC required labeling must also be placed in the required locations. This information can be obtained from your electrician or Washington State Labor and Industries. Locations for directory placards:

  • Utility Meter
  • Main Service Panel
  • Sub Panels (If present)
  • AC disconnect / Production meter

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with Klickitat PUD 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.
