1.0 DESCRIPTION OF THE GENERATING FACILITY

City of Redmond (“Applicant”) has proposed interconnecting 60.8 kW DC of new generation to PacifiCorp’s (“Electric Company”) existing 12.47-kV Circuit, 5D226, located in Redmond, OR.

The Applicant’s generation project will provide a nameplate output of 58 kW of AC generation.

2.0 APPROVAL CRITERIA FOR LEVEL 2 INTERCONNECTION REVIEW

Pursuant to 860-039-0035(1) An Electric Company must apply the following Level 2 interconnection review procedure for an application to interconnect an eligible system that meets the following criteria:

(a) The facility has a capacity of two megawatts or less; and

(b) The facility does not qualify for or failed to meet applicable Level 1 interconnection review procedures.

3.0 PROPOSED POINT OF INTERCONNECTION

The proposed generation facility is to be interconnected to the existing 5D226 Circuit (12.47-kV), out of Redmond Substation. The Applicant is looking to interconnect to facility point number 01415013.0098280.

4.0 TIER 2 INTERCONNECTION REVIEW RESULTS

4.1 860-039-0035(2) (a) The aggregate generation capacity on the distribution circuit to which the net metering facility will interconnect, including the capacity of the net metering facility, will not cause any distribution protective equipment (including, but not limited to, substation breakers, fuse cutouts, and line reclosers), or customer equipment on the electric distribution system, to exceed 90 percent of the short circuit interrupting capability of the equipment. In addition, a net metering facility will not be connected to a circuit that already exceeds 90 percent of the short circuit interrupting capability, prior to interconnection of the facility.

Project fails review criteria?: False These calculations use a generation power factor of 0.95, a single-phase fault current multiplier of 5, a three-phase fault current multiplier of 3, and line-to-line primary voltage of 12.47 kV.

Existing single-phase private generation: 134 kW.

Single-phase current produced on primary during normal operation: 19.59 Amps.

Single-phase current produced on primary during a fault condition: 98.0 Amps.

Existing three-phase private generation: 4.3 kW.

Three-phase current produced on primary during normal operation: 0.21 Amps.

Three-phase current produced on primary during a fault condition: 0.6 Amps.

Current produced by proposed generation system on primary: 2.83 Amps.

Current produced by proposed generation system on primary during a fault condition:

8.5 Amps.

Total fault current: 107.1 Amps.

The limiting distribution protective equipment is a single phase fuse cutout, with a rating of not less than 8000 Amps.

8000 x 0.9 = 7,200.0 Amps.

4.2 860-039-0035 (2) (b) If there are posted transient stability limits to generating units located in the general electrical vicinity of the proposed point of common coupling, including, but not limited to within three or four transmission voltage level busses, the aggregate generation capacity, including the net metering facility, connected to the distribution low voltage side of the substation transformer feeding the distribution circuit containing the point of common coupling will not exceed 10 megawatts.

Project fails review criteria?: False Are there posted transient stability limits to generation?: No

Aggregate single-phase generation on feeder: 134 kW Aggregate three-phase generation on feeder: 4.3 kW Proposed generation system: 58 kW

Total generation on circuit (existing and proposed): 196.3 kW Generation limit: 10 MW

4.3 860-039-0035 (2) (c) The aggregate generation capacity connected to the distribution circuit, including the net metering facility, will not contribute more than 10 percent to the distribution circuit's maximum fault current at the point on the high voltage (primary) level nearest the proposed point of common coupling.

Project fails review criteria?: False Fault current at the point of interconnection without the contribution of customer generation = 3540 Fault current at the point of interconnection with the contribution of customer generation included = 3576

(3576 Amps - 3540 Amps) / 3540 Amps x 100 = 1.02%

4.4 860-039-0035 (2) (d) If a net metering facility is to be connected to a radial distribution circuit, the aggregate generation capacity connected to the electric distribution system by non-public utility sources, including the net metering facility, will not exceed 10 percent (or 15 percent for solar electric generation) of the total circuit annual peak load. For the purposes of this subsection, annual peak load will be based on measurements taken over the 12 months previous to the submittal of the application, measured for the circuit at the substation nearest to the net metering facility.

Project fails review criteria?: False Peak load on circuit 5D226: 4200 kW

Percentage of peak load for comparison (use 15% for solar, 10% for other generation types): 630 kW

Total customer generation on circuit (existing and proposed): 196.3 kW

4.5 860-039-0035 (2) (e) If a net metering facility is to be connected to three-phase, three wire primary public utility distribution lines, a three-phase or single-phase generator will be connected phase-to-phase.

Project fails review criteria?: False Circuit 5D226 is Three-Phase, Four Wire.

Generation is connected phase-to-phase?:

4.6 860-039-0035 (2) (f) If a net metering facility is to be connected to three-phase, four wire primary public utility distribution lines, a three-phase or single-phase generator will be connected line-to-neutral and will be effectively grounded.

Project fails review criteria?: False This review item refers to a customer generation facility’s ability to manage a transient overvoltage condition. This can be accomplished by using a qualified inverter or by effectively grounding the generation system.

IEEE 1547.7 guidelines indicate this review item may be waived if the aggregate customer generation is less than 10% of the circuit’s Light Load (for solar generation, the Daytime Light Load is used).

Light Load = 1600 kW 10% of Light Load = 160 kW Sum of customer generation (existing and proposed): 196.3 kW

Transient overvoltage management has been achieved for this installation, either through the use of a qualified inverter or by the addition of an effective grounding system?: True

4.7 860-039-0035 (2) (g) If a net metering facility is to be connected to a single-phase shared secondary, the aggregate generation capacity on the shared secondary, including the net metering facility, will not exceed 20 kilovolt-amps.

Project fails review criteria?: False Phasing of this installation: Three Phase Existing customer generation on the secondary: 0 kW Review item has been cleared by Engineering?:

4.8 860-039-0035 (2) (h) If a net metering facility is single-phase and is to be connected to a transformer center tap neutral of a 240 volt service, the addition of the net metering facility will not create a current imbalance between the two sides of the 240 volt service that is greater than 20 percent of the nameplate rating of the service transformer.

Project fails review criteria?: False This review item refers to connecting a single-phase 120 V inverter on a single-phase 240 V service.

Phasing of this installation: Three Phase Voltage of this installation: 208V Existing load on service transformer: kW

4.9 860-039-0035 (2) (i) A net metering facility's point of common coupling will not be on a transmission line.

Project fails review criteria?: False This installation will interconnect on distribution circuit 5D226.

4.10 860-039-0035 (2) (j) If an eligible system's proposed point of common coupling is on a spot or area network, the interconnection must meet the following additional requirements:

A) For a net metering facility that will be connected to a spot network circuit, the aggregate generation capacity connected to that spot network from the net metering facilities, and any generating facilities, will not exceed five percent of the spot network's maximum load;

(B) For a net metering facility that utilizes inverter-based protective functions, which will be connected to an area network, the net metering facility, combined with any other generating facilities on the load side of network protective devices, will not exceed 10 percent of the minimum annual load on the network, or 500 kilowatts, whichever is less.

For the purposes of this paragraph, the percent of minimum load for solar electric generation net metering facility will be calculated based on the minimum load occurring during an off-peak daylight period; and

(C) For a net metering facility that will be connected to a spot or an area network that does not utilize inverter-based protective functions, or for an inverter-based net metering facility that does not meet the requirements of paragraphs (A) or (B) of this subsection, the net metering facility will utilize low forward power relays or other protection devices that ensure no export of power from the net metering facility, including inadvertent export (under fault conditions) that could adversely affect protective devices on the network.

Project fails review criteria?: False Circuit 5D226 is a Radial circuit.

Sum of customer generation (existing and proposed): 196.3 kW

Peak load on circuit 5D226: 4200 kW 5% of peak load on circuit : 210.0

Technology type of proposed generating facility: Inverter Light Load = 1600 kW 10% of Light Load = 160 kW
