Net Metering

Net Excess Generation Notes

Net metering shall be accomplished using a single meter capable of registering the amount (flow) of electricity which flowed in each direction during a billing period.

If the kWh generated by the Customer and then delivered to Company exceeds the kWh supplied by the Company to Customer during the billing period, the Customer shall be credited the kWh difference (excess generation credit).

The Customer may request in writing a refund that amounts to, but is not greater than, an annual true-up of accumulated credits over a twelve month period.

Plans & docs

Site Plan Reqs

• Clearly list the inverter make and model (e.g., SolarEdge SE3800H-US) in both the Site Plan and ELD - do not use part numbers.
• Disconnect needs to be labelled as AC Disconnect

SLD Reqs

All Jobs

• The one-line diagram should show all electrical equipment from Duke Energy’s metering location to the energy source including switches, fuses, breakers, panels, transformers, inverters, energy source, wire size, equipment ratings and transformer connections.
• If using micro inverters, show the wattage on the line diagram
• Clearly list the inverter make and model (e.g., SolarEdge SE3800H-US) in both the Site Plan and ELD - do not use part numbers.
• For SE5700H-US inverters, specify the AC system size as 5.760 kW, not a rounded value like 5.700 kW.

Battery Projects

• Utility wants to see the isolation disconnect (PV + battery) between the gateway and utility meter / MSP (depending on the gateway connection). In this configuration, it acts as a Gateway disconnect, if applicable, see Gateway disconnect in Files section for example.
•  A standard fused disco would be needed when intercepting supply feeders, and a standard unfused disco needed when intercepting on load side feeders

Install Reqs

The switch must be installed on the interconnection customer's side of the electrical interconnection with the utility's system, accessible to utility personnel and located in close proximity to the utility's electrical delivery point. The switch may isolate the interconnection customer and its associated load from the utility's system or disconnect only the generator from the utility's system and shall be accessible to the utility at all times.

Placards

The switch must be labeled "Generator Disconnect Switch".

Site Plan Notes

 The AC disconnect must be within 5' and in sight of the utility meter and both must remain outside.
