Question 12.

Section TS.11.4: Discharge Resistant EPR is exempt from partial discharge testing per ICEA. Is this acceptable?

Response 12.

Yes. DR-EPR insulation systems that are exempt from routine partial discharge testing under the applicable ICEA standards are acceptable, provided the cable complies with all other applicable KUA specification requirements and the referenced ICEA and AEIC standards. At a minimum, the cable shall remain subject to the applicable qualification and production tests, including the high-voltage AC test, end-to-end shield resistance measurement, water penetration production test for filled strand cable construction, and all other required AEIC CS8 / ICEA S-94-649 production and qualification testing. KUA reserves the right to require certified test reports demonstrating compliance with these tests for the cable design and production lot furnished.

Questions Regarding OUC Specs (13-20):

Question 13.

In the spec, some of the items require a water blocked test to be conducted under ICEA T-31-610, while some of the requires ICEA T-34-664. Please clarify if that shall be followed per case by case specified per items, or one uniform test for overall testing of stock items.

Response 13.

ICEA T-31-610 will be used for all cables.

Question 14.

In the spec, some of the items require three red stripes, while some of the items do not specify.

Please clarify if Red striping should be conducted for selected items in the spec or considered as an overall uniform requirement.

Response 14.

Three red stripes are required for all cables.

Question 15.

ANSI C119.4 Connection Test Report: LS Cable is unable to provide the requested report at this time prior to two weeks before bid opening. Because cable splice fittings have various manufacturers with various fitting types related to cable splicing accessories. Due to these variants, the performance will be different on the splicing accessories. Will cable compatible with any splice kit manufacturer and kit type that is made per industry-recognized standards and listings suffice?

Response 15.

Yes.

Question 16.

OUC SPEC SHEET #018-55100 - The 11-#14 CU Concentric Neutral called out for stock number 018-55100 is not equivalent to a 1/3 neutral for a 1000KCM AL conductor. Does this cable construction require an 11-#14 neutral configuration or a 1/3 (20-#10) neutral configuration?

Response 16.

A revised OUC SPEC SHEET #018-55100 was attached with the concentric neutral requirement (18-#10 strands of AWG uncoated copper wire).

Question 17.

EPR Cable:

For Discharge Resistant EPR cables will a nonconducting conductor shield as recognized and accepted by both ICEA and AEIC be acceptable?

Response 17.

Yes.

Question 18.

Our DR-EPR is class/type III/IV. ICEA S-94-649, AEIC CS8 both accept this type. Is this acceptable to OUC?

Response 18.

Yes.

Question 19.

DR-EPR cables are manufactured using a 1+2, triple tandem extrusion process which allows for 100% continuity test of insulation shield. Is this acceptable?

Response 19.

Yes.

Question 20.

Specification 018-55100 requires 11#14 AWG neutrals for 1000kcmil cable and states this is 1/3rd.

We will provide 1/3rd neutral per ICEA guidelines for 1000kcmil of 20 #10 AWG neutrals. Is this acceptable?

Response 20.

No, we want to use 18-#10 wire for flexibility. Revised specification attached.

Question 21.

Attachment A (2.3) Indicate what indexes and time period the price movements will be tied to.

Is there a preferred set of indexes that the end user utilities would prefer to be used in the bid submittal?

Response 21.

Copper (Primary Conductor Material) COMEX Copper Futures

• Source: CME Group

• Basis: Monthly average settlement price

• Usage: Most common index for copper conductor adjustment

Aluminum (Overhead T&D Conductors)

• London Metal Exchange Aluminum

Insulation & Polymer Indices (Underground/Covered Conductors)

• Producer Price Index (PPI) for Plastic Materials and Resins o PPI Resin specific weighting [e.g.,XLPE, PVC, HDPE] (WPU063201) o PPI for general insulation adjustments (WPU063)

Steel Component Indices (ACSR, Guy Wire) Producer Price Index for Steel Wire (WPU101706)

Question 22.

Can OUC provide the metals base that they would like pricing to be calculated from?

Response 22.

Question 23.

There is still some confusion regarding OUC’s response to the following question.

Can OUC provide the specific metal base values they would like pricing to be calculated from? We appreciate the clarification on the indices; however, there is still some ambiguity regarding the actual metal bases to be used. Identifying the specific dollar value for each metal base is important to ensure proposals are simplified and evaluated equitably. Would OUC be willing to provide the actual metal base values that should be used for pricing calculations? For example:

Copper: COMEX monthly average settlement price – February: $5.8590/lb Aluminum: Platts Metals Week U.S. Transaction (including Midwest Premium) – February: $2.4303/lb These indices are commonly used in North America, and the COMEX and Platts U.S.

Transaction index is used on your current wire and cable contracts.

Response 23.

After careful consideration, OUC recommends the following metal base values and indices for use in all proposal pricing calculations:

COPPER

Index: COMEX Monthly Average Settlement Price Base Month: February 2026 Base Price: $5.8590/lb This is consistent with the index currently used in OUC's existing wire and cable contracts and represents the confirmed COMEX monthly average settlement price for February 2026, as widely published by industry sources. COMEX is the globally recognized benchmark for copper pricing in North America and provides a transparent, liquid, and auditable reference point for contract escalation and de-escalation.

ALUMINUM

Index: LME Cash Price + U.S. Midwest Premium (Platts MW U.S. Transaction Price) Base Month: February 2026 All-In Base Price: $2.44/lb (approximate) Breakdown:

• LME Aluminum Cash Price (February 2026): ~$1.45/lb (~$3,200/metric ton)

• U.S. Midwest Premium (February 2026): ~$0.99/lb (~$2,182/metric ton)

• All-In Combined Price: ~$2.44/lb OUC recommends this two-component structure for aluminum pricing because it more accurately and transparently reflects the true all-in cost of primary aluminum in the U.S.

physical market. The LME cash price represents the global base metal value, while the U.S.

Midwest Premium — assessed and published by S&P Global's Platts Metals Week — captures the domestic U.S. supply/demand dynamics, regional logistics costs, and the impact of current Section 232 tariff policy. Together, these two indices constitute the standard "all-in" price that U.S. wire and cable manufacturers actually pay for primary aluminum today.

It is important to note that February 2026 represents a historically elevated pricing environment for aluminum, particularly with respect to the Midwest Premium, which has reached record levels due to the impact of 50% Section 232 tariffs on Canadian aluminum imports. All prospective suppliers should factor this market reality into their proposals and pricing adjustment mechanisms accordingly.

OUC requests that all vendors use the above base values as the standard starting point for their pricing submissions. Any escalation/de-escalation formula included in proposals should

100 W. Anderson Street l PO Box 3193 l Orlando, FL 32801 l 407-434-2701 Telephone l www.ouc.com clearly reference these same indices so that OUC can evaluate and compare all proposals on a level playing field.

Question 24.

Attachment A (2.3) says to indicate the time period that the price movement is tied to. Should that time period be set so that everyone is on the same level?

Response 24.

Per Attachment A (2.1) The preferred frequency of price adjustment is monthly.
