3. Summary and Description of Owner’s Distributed Generation Equipment/Facility to be Included in Exhibit A.
3.1 The Owner’s eligible Distributed Generation System is a self-contained electric generation system
including direct current disconnect apparatus, if applicable, alternating current disconnect/lockout, over-current
protective device, and all related electrical equipment upstream of the over-current protective device, as set forth on
Exhibit A (the “System”). The System begins and continues up-stream towards the distributed generation from the over-
current protective device on the Owner’s premises. However, the meter socket and related electrical connects are part
of the System and are the responsibility of the Owner [i.e. all equipment from the main disconnect except the meter is
Owner equipment].
3.2 Capacity of the Distributed Generation equipment is: __________kW.
3.3 The expected annual energy production of the Distributed Generation equipment is ______kWh.
3.4 The expected date of initial operation of the Distributed Generation equipment is: ___________.
4. Installation and Permitting
4.1 Without limiting the provisions of paragraph 22, the Owner and the System must comply with all
applicable National Electric Code (NEC), UL and IEEE requirements, including, but not limited to:
UL 1741-Standard for Static Inverters and Charge Controllers for Use with Photovoltaic Systems.
IEEE Standard 1547 (2003): Standard for Interconnecting Distributed Resources with Electric Power Systems.
[NOTE: UL 1741 will soon be incorporated into IEEE 1547].
Other organizations, such as the Canadian Standards Association (CSA), test to UL 1741. If the inverter is tested
by an organization other than Underwriters Laboratories, the test data must be submitted to BLW.
The Owner at the Owner’s expense must: 1) obtain all necessary electrical permits for installation of the System
and 2) obtain and maintain any government authorizations or permits required for the operation of the System. The
Owner must reimburse BLW for any and all losses, damages, claims, penalties, or liability BLW incurs as a result of
Owner’s failure to obtain or to maintain any governmental authorizations and permits required for construction and
operation of the Owner’s System.
4.2 The Owner or its contractor must construct the System as specified in the attached Exhibit A.
4.3 A manual, lockable, load-break disconnect switch that provides a clear indication of the switch position
must be available with the System at or near the Owner’s main point of service from BLW’s electric system to provide a
point of electrical separation between the Owner’s System and BLW’s electric system. BLW will approve the location of
the disconnect switch. The disconnect switch must be easily visible, mounted separately from the metering equipment,
readily accessible to BLW personnel at all times, and capable of being locked in the open position with BLW’s lock. BLW
may open the disconnect switch thereby isolating the Owner’s System from the BLW electric system for any reason that
BLW deems necessary including, but not limited to, maintenance or emergency work, the System adversely affecting
other customers of BLW, failure of the System to comply with codes/regulations, the System creating hazardous or
unsafe conditions, the Owner’s failure to pay utility bills when due, and failure to comply with the UL Standards in
Section 4.1 above.
4.4 Power Quality Requirements. All power quality parameters (i.e., voltage, flicker, frequency, distortion)
are specified at the point of common coupling (PCC) unless otherwise stated. The following requirements must be met:
~ 3 ~
4.4.1. Voltage the System must be capable of operating within normal voltage operating limits of
106-132 volts (88 -110% nominal 120V). This range results in trip points at 105 volts and 133 volts.
Response to abnormal voltages should be as follows:
Voltage (at PCC) Maximum Trip Time
V<50% 10 cycles
50%≤ V<88% 120 cycles
88%<V<110% normal operation
110%<V<120% 60 cycles
V≥ 120% 10 cycles
4.4.2 Flicker The System shall not create objectionable flicker for other BLW customers. Flicker is
considered objectionable when it either causes a modulation of the light level of lamps sufficient to be
irritating to humans or causes equipment malfunction. See IEEE 519-1992.
4.4.3 Frequency The System must have a fixed frequency range of 59.3 to 60.5 Hz. When the
interconnected system frequency is outside this range, the System shall cease to energize the BLW
connection within 1-cycle.
4.4.4 Waveform Distortion (Harmonics) - The System must have low current-distortion levels to
ensure that no adverse effects are caused to other equipment connected to BLW’s electric system.
When the System is serving balanced linear loads, harmonic current injection into BLW’s network shall
not exceed when measured in accordance with IEEE Std 1547:
harmonics h<11 11≤ h<17 17≤ h<23 23≤ h<35 35≤ h
per cent 4.0 2.0 1.5 0.6 0.3
Maximum Total Demand Distortion (TDD) 5.0%
Even harmonics are to be limited to 25% of the odd harmonics shown above.
4.4.5 Power Factor The System must operate at a power factor >0.85 (leading or lagging) when
output is greater than 10% of full load.
4.4.6 Islanding Protection The System must cease to energize the utility line when the inverter is
subjected to islanding conditions. The System must immediately, completely and automatically
disconnect from BLW’s electric system in the event of a fault on the Owner’s System or loss of source on
BLW’s electric system. BLW, at its own discretion and expense, may conduct periodic testing of anti-
islanding. Anti-islanding is a means by which the Owner’s System will cease to generate when it is still
connected to the isolated (due to fault clearing or other switching) section of the BLW electric system.
4.5 The Owner’s over-current protective device (Breaker) at the service panel must be dedicated and must
be capable of interrupting the maximum available fault current. The Breaker shall be clearly marked to indicate power
source and connection to BLW’s electric system. BLW will provide and attach an additional label to the manual load-
break disconnect switch, which is described in Subsection 4.3 above.
4.6 The Owner, at the Owner’s expense, must pay for any additional equipment required to connect the
System to BLW’s electric system.

5. Written Authorization Required to Connect System
The Owner may not connect the System to BLW’s electric system until: 1) this Agreement has been fully
executed by the parties, 2) the System has been tested, and 3) written authorization to connect the System, in a form
substantially similar to Attachment B, has been given to the Owner by BLW. BLW may have representatives present at
the initial testing of the Owner’s System and may perform (at its own expense) whatever testing of the Owner’s System
that BLW deems necessary.
After written authorization to connect the System to BLW’s electric system has been given, the Owner shall
make no changes or modifications in the System or of its mode of operation without the prior written approval of BLW.
6. Warranty is Neither Expressed nor Implied
