• INTERCONNECTION AND PARALLEL OPERATION

Interconnection with the Company’s system requires the installation of protective equipment whichprovides safety for personnel, affords adequate protection against damage to the Company’s system or tothe Customer’s property, and prevents any interference with the Company’s supply of service to otherCustomers. Such protective equipment shall be installed, owned and maintained by the Customer at theCustomer’s expense. The Customer’s equipment must be installed and configured so that paralleloperation must cease immediately and automatically during system outages or loss of the Company’sprimary electric source. The Customer must also cease parallel operation upon notification by theCompany of a system emergency, abnormal condition, or in cases where such operation is determined tobe unsafe, interferes with the supply of service to other Customers, or interferes with the Company’ssystem maintenance or operation. Generation systems and equipment that comply with the standardsestablished in the previous Section of this Rider shall be deemed by the Company to have generallycomplied with the requirements of this Section

SPECIAL PROVISIONS1. The customer must pay all interconnection charges before the Company will purchase

electric power.2. A customer's installation must conform to Company specifications for Qualifying Facility

interconnection as outlined in the Company's Technical Guidelines for Cogeneration and Small Power Producers.

3. Qualifying Facilities with 10 kW or less generating capacity must sign an Electric Interconnection/Small Power Purchase Agreement.

4. Purchases from a QF will receive a capacity credit when the capacity exceeds 100 kilowatts and that capacity meets certain reliability criteria. The Company will make capacity payments to the QF to the extent that the capacity of the QF reduces any capacity deficiency payments by the Company to PJM or increases any capacity payments to the Company from PJM. Capacity credits, if applicable, will be based on the average on-peak capacity in any billing month, such capacity to be defined as the on-peak kilowatt-hours divided by the on-peak hours in that month. The seller may be eligible for an additional credit where the presence of the QF allows the deferral of local transmission or distribution capacity cost.

5. The Service Charge will be waived for QF's with 10 kW or less generating capacity.6. Due to simplified metering, QF's with 10 kW or less generating capacity will be credited

based on the average non-load weighted PJM billing rate for the month the energy is received.

• General Interconnection and Protection Requirements

• The Generator Owner’s generation and interconnection installation must meet all applicable national, state, and local construction and safety codes.

• The Generator Owner’s generator shall be equipped with protective hardware and software designed to prevent the generator from energizing one of the Company’s de-energized circuits. The Generator Owner’s generator must automatically disconnect from the Company’s system if the Grid source is lost, irrespective of connected loads or other generators.

• The generator shall be equipped with the necessary protective hardware and software designed to prevent sustained parallel operation of the generating equipment with the Company’s system unless the system service voltage and frequency are within acceptable magnitudes as defined in Section XIV.B.

• Pre-approved equipment shall be accepted as part of an interconnection proposal without the need to re-review the equipment itself. However, the application, design and setting of pre-approved units and/or equipment must be reviewed and coordinated according to the unique needs of the specific location of the proposed installation. Where a complete unit or system has been pre-approved, only location-specific issues will typically need to be reviewed.

• The Generator Owner will be responsible for protecting its own generating and interconnection equipment in such a manner so that Company system outages, short circuits, single phasing conditions or other disturbances including zero sequence currents and ferroresonant over-voltages do not damage the Generator Owner’s generating equipment. The protective equipment shall also prevent excessive or unnecessary tripping that would adversely affect the Company’s service reliability to other Generator Owners and Customers.

• The Generator and interface protection schemes shall be continuously monitored and functioning and the generator shall immediately disconnect from the Company’s system for any condition that would make the protection scheme inoperable.

• The operating power required for the protection and control schemes for the generator and the control power used to disconnect the generator from the Company must not be dependent on local Company grid power.

• Where multiple generators are connected to the system through a single point of common coupling, the sum of the ratings of the generators will be used to determine the applicability of these guidelines. Protection scheme performance with one or more units off line will have to be considered .

• Applicable circuit breakers or other interrupting devices at the Generator Owner’s facility must be capable of interrupting the maximum available fault current at the site, including any contribution from the Owner’s generator(s).

• The Generator Owner will furnish and install a manual disconnect device which, when opened, will have the affect of isolating the generator from the Company’s system. This disconnect device shall have a visual break (a disconnect switch, a draw-out breaker, fuse block, etc. as appropriate to the voltage level), will, at all times, be accessible to Company’s personnel, and shall be capable of being locked in the open position via a Company padlock. The Company shall use reasonable efforts to utilize padlocks of a size consistent with typical manufacturer’s specifications. The Generator Owner shall follow the Company’s switching, clearance and tagging procedures which the Company shall provide and attached the Warning Label noted in Section X.

• On generation installations of 25kW or less, the Generator Owner may elect not to install a manual disconnect switch provided that the meter can be safely “pulled” by Conectiv to isolate the generation equipment from the Company. If the Generator Owner elects not to install a manual disconnect device, the Generator Owner assumes all risks and consequences when a meter must be “pulled” to disconnect the generator thereby also interrupting electric service to the Customer.

• The design, procurement, installation, and maintenance of the equipment at the Generator Owner’s site is the responsibility of the Generator Owner and at the Generator Owner’s expense.

• Any necessary enhancements or improvements needed within the Company’s system and/or at other Customer sites to accommodate the parallel interconnection of the Generator Owner’s generation will be at the Generator Owner’s expense.
