Brand Name Justification

Western Area Power Administration

FAR 13.106-1(b)(1), Simplified Acquisitions

PR 22WA142220

1. Identification of the agency and the contracting office.

Western Area Power Administration, 615 South 43rd Ave Phoenix Arizona 85009

2. Description of supply or service required to meet the agency’s needs.

This brand name procurement action is to provide three (3) new HMB 8.11 operating mechanisms, including wiring harness, part number 641C25201, to be configured to an 242PA40-20 type breaker with serial number C00507-108. The new HMB 8.11 mechanisms are a customized mechanism to replace the existing HMA 8 mechanisms on this ABB breaker type.

3. The rationale or circumstances for limiting competition.

Limited Competition is due to the following: The 242PA breakers needing repairs is in a ring bus type configuration and repairs need to be made due to the failure of the operating mechanism actuators. This restricts the capabilities of the Electrical Grid and puts us in what is known as an N minus1situation.

This means if we have any other problems with the remaining breakers currently in service it would cause a disruption to the Power Grid and customers could lose service. The breakers are in our 230 kV system at Rogers Substation which is a critical path on our system. ABB will provide three new HMB

8.11 Mechanisms that is customized to fit this type of breaker. The new mechanisms will be configured to breaker serial number C00507-108, where it is a cost-effective method to upgrade and extend the life of the breakers. ABB has the knowledge, ability and expertise to provide the materials required due to being the manufacturer of this breaker that has this type of mechanism.
