Net Excess Generation Notes

If the customer-generator’s facility feeds more kWh of electricity back to the Company’s system than the Company supplies to the customer during the billing period, only the generation-related energy charges of the customer’s standard service schedule, including all applicable generation-related riders, shall be calculated using the customer’s net energy supplied to the Company. All other energy charges shall be calculated using an energy value of zero (0) kWh. If the customer’s net billing under the standard service schedule is negative during the billing period, the negative net billing shall be allowed to accumulate as a credit to offset billing in the next billing period. The customer may request, in writing, a refund of accumulated credit that is no greater than an annual true-up of accumulated credits over a twelve month period.

System Offset Notes

If the generating system ever produces more than one hundred twenty percent of the customer’s electricity than is needed for any 12-month period, then the account doesn’t qualify for the net metering tariffs.

Load justifications/engineering calculations showing the customer is expected to consume more energy in the near future due to an addition of an electrical system (EV charger, switch to electric heating, etc.) is accepted by the utility and will be reviewed on a case by case basis.

SLD Reqs

All Jobs

• SLD must be a legible schematic diagram of the entire generating equipment system.
• A title block with the customer's name, service address, installer name and date must be included.
• It should contain all the electrical equipment from the AEP Ohio meter to the generator including switches, fuses, breakers, panels, transformers, inverters, energy source, wire size, equipment ratings and transformer connections.
• If there are any existing generators, include the same items and information for them.

Battery Projects

• Batteries must have its own disconnect

Install Reqs

Production meter not required.

AC disconnect should be within 6 feet of the AEP Ohio meter. It cannot be in an enclosed area, if there is a unique situation where an existing AEP Ohio meter is located inside a building or enclosed area, then the disconnect switch can be located next to the AEP Ohio meter.

Locating the disconnect switch anywhere other than next to the AEP Ohio meter will require preapproval from the DG Coordinator and a permanent plaque must be installed next to the AEP Ohio meter that clearly identifies the location of the disconnect switch.

The disconnect switch itself must be lockable such that AEP Ohio can lock the position of the switch in place using a padlock (a lockable cover on the switch does not meet this requirement), and plainly indicate whether it is in the open (off) or closed (on) position.

If the disconnect switch is on the load side of the main disconnect means then it could be a solid blade switch or the DC switch for the inverter, provided it meets all other NEC requirements.

If the disconnect switch is on the supply side of the main disconnect means it must be an AC switch and if the electric service is a three phase supply it must be a three phase automatic isolating device. Also, it must meet all other NEC requirements.

Placards

AC Disconnect must be properly labeled such as "Generator AC Disconnect Switch".
