About this file
This document is Addendum 2 for KEYS Bid 12-25, issued by Keys Energy Services in Key West, Florida, concerning specifications for the purchase of a power transformer. The addendum provides clarifications and answers to vendor questions regarding the transformer procurement. KEYS will evaluate proposals for three bid options: a base bid with an all stainless steel tank, and two alternate bids with mild steel tank configurations. The scope of work includes fabrication, delivery, unloading, field assembly, and field testing, with KEYS providing the foundation upon transformer arrival. All transformer designs must include stainless steel radiators, control cabinet, and nitrogen cabinet, with alternate paint options acceptable if deemed equivalent by KEYS.
The bid allows for international manufacturers to submit proposals, provided all ANSI, IEEE, and NEMA standards are fully met, though KEYS maintains a preference for North American manufacturing. A U.S.-based service partner is acceptable for field service availability. The transformer requires specific technical characteristics, including C400 accuracy class for current transformers (except X1 and X2, which are C100), and there are no clearance concerns at the substation. KEYS is open to bids from manufacturers in countries like South Korea, with flexibility in tank material and paint specifications. An outline drawing (SLM5139-01) of the existing transformer is attached for reference, and KEYS can assist with coordination efforts if barge delivery is necessary due to bridge restrictions in the Florida Keys.

KEYS BID 12-25 SPECIFICATIONS FOR PURCHASE OF POWER TRANSFORMER
Addendum 2
Questions and Answers:
1. Are the two Stainless Steel tank requirements a Must Have for Keys Energy to evaluate a Bid?
KEYS will evaluate proposals received for the base bid, alternate bid 1, or alternate bid 2. Bidding one of the three options is acceptable.
2. Can international manufacturers (outside North America) submit bids provided all ANSI, IEEE, and NEMA standards are fully met?
Yes. Bids from international manufacturers, provided that all applicable ANSI, IEEE, and NEMA standards are fully met can be submitted as well.
3. Would a domestic U.S.-based service partner satisfy the requirement for field service availability in the Southeast?
Yes., a U.S.-based service partner is acceptable.
4. If barge delivery is required due to bridge restrictions, will KEYS assist with coordination or provide guidance for offloading at the Florida Keys Aqueduct facility?
Yes. KEYS can assist with coordination efforts and provide guidance for offloading at the Florida Keys Aqueduct facility, if barge delivery becomes necessary due to bridge restrictions.
5. This RFQ requires 1 design for full stainless-steel tank and radiators. A second design is for a steel tank with stainless steel cover and stainless-steel radiators. We can’t build all stainless steel tank, but we can build a steel tank with a stainless steel cover. We can’t use stainless steel radiators. Also, we won’t be able to use the Acrolon Ultra High gloss paint. We will use our standard paint. Will the customer accept a bid with these exceptions?
There are 3 options to bid:
-All stainless steel tank (Base bid) -Mild steel tank with stainless steel top (alternate bid 1) -All mild steel tank (alternate bid 2)
All 3 options must have stainless steel radiators, stainless steel control cabinet, and stainless steel nitrogen cabinet.
Alternate paint options are acceptable if KEYS deems it to be an equivalent.
6. Is the following Scope-of-Work correct for each Vendor and included in their selling Price: 1. Deliver Transformer to Key West, FL. 2.Unload Transformer onto permanent

Foundation. Foundation supplied by Keys Energy Services. 3. Field Assemble Transformer including Oil-Filling. 4. Field Testing.
Yes. The scope of work includes fabrication, delivery, unloading, field assembly, and field testing. KEYS will have a foundation ready upon transformer arrival.
7. The current Transformer Accuracy is not specified in spec-please provide. Also, this seems to be a replacement unit. Can you confirm if there are any dimension restrictions? If possible, please provide the dimensions or the previous nameplate.
All CT’s should be C400 accuracy class except for X1 and X2, which are C100s. An outline drawing of the existing transformer is attached for reference. Clearance issues are not a concern at this substation due to ample space.
8. Would you be open to considering a bid for transformers manufactured in South Korea, including the steel tank?
While KEYS maintains a preference for North American manufacturing, bids from international manufacturers can be submitted as well, provided that all applicable ANSI, IEEE, and NEMA standards are fully met
