Rider NEM

• INTERCONNECTION AND PARALLEL OPERATION
• Interconnection with the Companys system
  requires the installation of protective equipment
  which
• provides safety for personnel, affords adequate
  protection against damage to the Companys system
  or to
• the Customers property, and prevents any
  interference with the Companys supply of service
  to other
• Customers. Such protective equipment shall be
  installed, owned and maintained by the Customer
  at the
• Customers expense. The Customers equipment must
  be installed and configured so that parallel
• operation must cease immediately and
  automatically during system outages or loss of
  the Companys
• primary electric source. The Customer must also
  cease parallel operation upon notification by the
• Company of a system emergency, abnormal
  condition, or in cases where such operation is
  determined to
• be unsafe, interferes with the supply of service
  to other Customers, or interferes with the
  Companys
• system maintenance or operation. Generation
  systems and equipment that comply with the
  standards
• established in the previous Section of this Rider
  shall be deemed by the Company to have generally
• complied with the requirements of this Section

7
Rate Schedule SPP

• Small Power Purchase
• Availability
• Available to a "Qualifying Facility" (QF) as
  defined in Section 210 of the Public Utility
  Regulatory Policies Act of 1978 who also receives
  service under regular Company Rate Schedules RS,
  RS TOU-D, RS TOUE, MGS, AGS, or TS. The
  generation capacity of such facility must be less
  than 1000 kW.
• Qualifying facilities with capacity greater than
  1000 kW must negotiate customer specific
  contracts.
• These facilities are entitled to a contract at
  full avoided energy costs and, if eligible,
  capacity costs.
• Customer specific contracts are subject to
  approval by the New Jersey Board of Public
  Utilities.

8
Rate Schedule SPP

• SPECIAL PROVISIONS
• 1. 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.

Technical Interconnection Issues

• General Interconnection and Protection
  Requirements
• The Generator Owners generation and
  interconnection installation must meet all
  applicable national, state, and local
  construction and safety codes.
• The Generator Owners generator shall be equipped
  with protective hardware and software designed to
  prevent the generator from energizing one of the
  Companys de-energized circuits. The Generator
  Owners generator must automatically disconnect
  from the Companys 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 Companys
  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.

14
Technical Interconnection Issues

• 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 Owners generating
  equipment. The protective equipment shall also
  prevent excessive or unnecessary tripping that
  would adversely affect the Companys 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 Companys 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 Owners facility must be
  capable of interrupting the maximum available
  fault current at the site, including any
  contribution from the Owners generator(s).

15
Technical Interconnection Issues

• The Generator Owner will furnish and install a
  manual disconnect device which, when opened, will
  have the affect of isolating the generator from
  the Companys 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 Companys 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 manufacturers
  specifications. The Generator Owner shall follow
  the Companys 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
  Owners site is the responsibility of the
  Generator Owner and at the Generator Owners
  expense.
• Any necessary enhancements or improvements needed
  within the Companys system and/or at other
  Customer sites to accommodate the parallel
  interconnection of the Generator Owners
  generation will be at the Generator Owners
  expense.

16
Technical Interconnection Issues

• The Generator Owner has full responsibility and
  liability for the safe and proper operation and
  control of their equipment and the power
  originating from their generator. The Generator
  Owner is also responsible for synchronizing their
  generator(s) with the Companys system and
  maintaining a synchronous condition.
• The Generator Owner must immediately cease
  parallel operation upon notification by the
  Company if such operation is determined to be
  unsafe, interferes with the supply of service to
  other customers, or interferes with the Companys
  system maintenance or operation.
• The Company reserves the right to specify the
  type of transformer connection (e.g.
  delta-delta, wye-delta, wye-wye) that will be
  employed for all multiphase interface
  transformers consistent, where reasonable, with
  the Generator Owners power system.
