Net Excess Generation Notes

The current solar rate is referred to as “Banked” NET Metering. Any generation from the solar system will offset the customer's consumption at 1 kWh for 1 kWh rate. If the system generates more energy than the customer consumes, it will be added to their “bank”. This bank will either build or reduce depending on the system’s generation and the customer's consumption. If there are any kWh’s in the “bank” at the end of the customer's April billing, the kWh’s in the “bank” are paid out to the customer at the avoided cost.

Plans & docs

Site Plan Reqs

• Metering equipment shall be accessible to Adams-Columbia personnel. Accessible means the metering equipment must be capable of being accessed for programming, reading, probing, inspection, and service without climbing, removing obstacles, utilizing ladders, entering locked areas, etc. Metering equipment that is not readily accessible will be required to be made accessible by the member before interconnection of DG will be allowed.

SLD Reqs

• AC disconnect required
• Production meter required

Electric Service Reqs

INTERCONNECTION DISCONNECT SWITCH REQUIREMENTS

• A device capable of disconnecting DG facilities from the electrical distribution system shall be installed at every DG site within 10 ft of the utility electric meter on residential or single building structures. Disconnection device shall be located in an accessible location. If the disconnection device cannot be located within 10 ft of the utility electric meter, a permanent placard shall be installed on the meter socket indicating the location of the interconnection disconnect switch and distance in feet from the meter to the disconnection device.
• Disconnection device shall be mounted at a height between 30 and 72 inches.
• Disconnection device shall open with a visual break, be able to be locked open, be capable of disconnecting and de-energizing distributed generation and shall conform to technical guidelines and state requirements.
• The disconnection device should disconnect the DG only and should not disconnect any load.
• The DG facility shall only be interconnected with a single metered service.
• This means the member is not allowed to feed DG from one building’s electrical system into another building’s electrical system when the two buildings are separately metered.
• Remote buildings fed from main service panel or sub-panel.
• For facilities with multiple buildings where the DG is installed on a remote building, a permanent placard shall be installed on the meter socket indicating the location of the
• interconnection disconnect switch and distance in feet from the meter to the disconnection device.
• Main disconnection device for remote building may be used as the disconnection device at the meter. However, a separate DG only disconnect is recommended on the exterior of the remote building at the DG location.

BATTERY ENERGY STORAGE SYSTEMS

• Battery energy storage systems shall use UL 1741 utility-interactive inverters and a UL 1008 or similar approved isolation device.
• ACEC evaluates DG sites by the kW AC nameplate capacity. So, if the solar + storage is DC coupled, they share an inverter, we would evaluate the facility on that inverter. If they are AC coupled, they have separate inverters (one for solar, one for energy storage system (ESS)) and we would evaluate on the combined nameplate of each inverter, see example below. Solar + storage have numerous operating modes/functions that can limit potential adverse impacts which should be evaluated; however, the overall system size is driven by the AC nameplate ratings.

Install Reqs

Preferred Methods

• DG connected via properly sized sub-breaker downstream from the main in the service panel.

Not Permitted when connecting DG

• Splices
• Split Bolts
• Tap Connectors
• Insulation Piercing Connectors
• Installing more cables than lugs are designed to handle.
• Modifying or installing lugs in a meter socket, pedestal other than what is listed on the manufacturers drawing associated with the UL Listing.
• Any other modifications to meter sockets.

Placards

• It is the responsibility of the member to comply with any and all labels required by the NEC or other jurisdiction codes and requirements.
• Member shall provide and install a “Dual Power Source” label at the meter socket indication the operating voltage, maximum current and maximum power of the solar PV system that is installed. Member shall provide an “Interconnection Disconnect Switch” label at the DG disconnect.
• Permanent labeling is required; Labeling shall be rigid engraved plastic, engraved self-sticking brass, or engraved self-sticking aluminum.
• Labeling shall use a minimum of ¼ inch block lettering.
