SUMMARY OF CHANGES

SECTION SF 30 - BLOCK 14 CONTINUATION PAGE (SF 30)

The following have been added by full text:

AMENDMENT 0006 Q&A

83. Reference “1.4 GOVERNMENT EQUIPMENT INTERFACE, 1.4.4 Potential and Current Transformers “… One current transformer (CT) for each generator is available for the voltage regulators of the new excitation system …” Proper operation of the PSS requires a minimum of two CTs. Three CTs, one per each phase, is the recommended arrangement. See – from the PLANS document sent with the Solicitation – pages E611, E612 and E613. For the CTs that the Corps have already shown as planned for use with the AVR, seen in the coordinates G/F by 3/4 on the drawing, there are three CTs that route to the SEL-751A relay and only one that runs to the “DIGITAL EXCITER.” The other two run elsewhere. Would the government permit the secondary leads of these other CTs could be run to the new exciter as well.”

Answer: The referenced CTs are not permitted for use for the excitation system at this time. Offerors that require more than one (1) CT for implementation of a PSS should include consideration of the effort and cost for adding additional CT(s) as necessary for their system in their proposal.

84. Reference “2.4 POWER POTENTIAL TRANSFORMERS, 2.4.4 Enclosure “… The cubicles shall be of the totally enclosed, freestanding, dead-front type built on a suitable framework of structural steel or by an equivalent approved method. … For a PPT enclosure that is not, in the strictest sense, dead-front type, the protection from incidental contact with live conductors is formed with cabinet openings that are not casually opened, which can offer isolation from the conductors. Would the government review what is desired by “dead-front type” and allow touch safe construction appropriate for powerhouse environment?”

Answer: The described approach of closed cabinet openings offering isolation from conductors and touch safe construction are in line with Government expectations for “dead-front type” enclosure construction.

The NEC definition of “dead front” which is stated as “Without live parts exposed to a person on the operating side of the equipment” is the intent.

85. Reference “2.5 EXCITATION SYSTEM REQUIREMENTS, 2.5.1 General, 2.5.1.6 Electronic Equipment Components, All electronic equipment, such as amplifiers and logic circuits, shall be of solid state design using industrial or military grade discrete transistors or integrated circuits bearing JEDEC Solid State Technology Association registered device numbers, where possible. Non-JEDEC parts shall be identified and approved by the Government. The Bidder asks if the Corps will accept other means of identifying circuit boards – without requiring JEDEC labeling on individual solid state devices.”

Answer: As described in the referenced paragraph of the specifications, labeling and bearing registered device numbers “where possible” is required. Other means of identification are allowable where this may not be practically achieved.

86. Reference “2.5.7.6 Painting, “… Exterior surfaces shall then be primed, filled where necessary, and given not less than two coats of finish matching the color of the existing excitation cabinets. …” The factory can match color, if the customer is able to identify the color to match in a manner that is meaningful to paint suppliers. Can the government furnish a paint chip or a paint number?”

Answer: The existing paint color “Do It Best Alkyd Industrial Enamel”” and a paint sample can be provided after contract award upon request.

87. Question, 20 Jul (Basler): “2.5.10 Field Discharge, Surge Suppression, and Surge Withstand “… a path for the field current and to dissipate the stored energy in the field. The circuitry shall incorporate bi-directional thyristors with a field discharge varistor, or similar approved circuitry. …”Bidder asks for approval for thyristors and field discharge resistors to dissipate the stored energy in the field.”

Answer: The described approach would seem likely to be “similar circuitry” which would be considered for approval. Drawings and details of the proposed system would be provided as part of Submittals for Government approval after contract award.

88. Reference “2.6 EXCITATION SYSTEM CONTROLS, 2.6.12 Power System Stabilizer (PSS) 2.6.12.3 Input Signals “… The power signal shall be derived from an instantaneous watt transducer or equivalent digital algorithm, using three phase voltage and single phase current input signals …” Proper operation of the PSS requires a minimum of two CTs, as mentioned in 1.4.4 above. Three CTs, one per each phase, is the recommended arrangement.”

Answer: Reference Amendment 0006. See the Government’s response to Question 83.

89. Reference “2.7 EXCITER COMMUNICATION, 2.7.3 Human-Machine Interface (HMI) “… Provide the following minimum display parameters … (h) Limiter and protective device setpoints …” Given the CYBERSECURITY REQUIREMENTS, described in SECTION 01 35 70, Paragraph 1.3.9 as “configured using a role-based scheme so that normal operations occur using an Operator level account with minimum privileges required to operate the system. The Contractor shall document the minimum privileges required for the Operator level account. Administration-level (privileged access) accounts shall be required to perform any configuration changes on the system,” the use of the operator’s interface panel, to access limiters setpoints and protective setpoints, contradicts the protections intended. Making changes to limiters and protective functions is not among operations required to operate the system – and accommodating access via the HMI defeats the role-based scheme configured to protect the system from tampering. Changing Auto and Manual operation setpoints is common and those setpoints can be displayed. Limiter and protection setpoints may be accessed via PC with the appropriate level of access. However, limiter and protection setpoint adjustments in the HMI seem to be in conflict with Cybersecurity concerns in Section 01 35 70. The bidder asks the Corps to revise the requirement – to remove the access to the SETPOINTS of the limiters and protections in the digital excitation controller from the HMI panel requirements. The access to these parameters would be more securely accessed via equipment with privileged access and with consideration of the appropriate role in configuring the controller.”

Answer: The referenced paragraphs do not go into specific details regarding the level of access permissions or privileges required for accessing and editing various parameters. Such specifics will be addressed post award through coordination between the contractor and the Government, and subject to Government approval during factory testing and commissioning as well as in submittals such as the “Comprehensive Account List (Encrypted)” submittal item. Manufacturer philosophy and approach towards display and modification of these setpoints and parameters will be compared against specification requirements, and discrepancies will be reviewed and discussed for consideration.

90. Reference “2.7.3 Human-Machine Interface (HMI), “… Provide the following minimum display parameters …(i) PSS status and setpoint, including active / inactive setpoints …” PSS function blocks do not have a setpoint.

PSS status can be displayed such as Enabled/Disabled, Active/Non-Active, or PSS output. The meaning of “setpoint” for the PSS is unknown.”

Answer: PSS indication desired includes PSS Status (as Enabled/Disabled, Active/Inactive, as described in the question) and an indication of the setpoints for power output levels at which the PSS becomes active/inactive. The second are the desired "setpoints" to be displayed for the PSS. Again, manufacturer typical practice may be considered and the final approach utilized will be addressed post award.

91. Reference “Page 5 of 76. CLIN 0014 is listed here as ‘Refurbish exciter collector ring assembly’ whereas under section 01 22 00, item it is listed as ‘Performance and payment bonds’. Please clarify.”

Answer: Reference Amendment 006. CLIN 0014 was revised to be consistent with the specifications.

92. Reference “Page 53 of 76. FAR 52.211-10. It is noted that the project completion is 540 calendar days after notice to proceed. Are there any outage duration limitations, number of units in outage or restrictions when the outages can be scheduled etc? Please advise.”

Answer: Reference Amendment 0005. See the Government’s response to Question 41.

93. Reference “Is a Primavera schedule required for the proposal or can it be MS project?”

Answer: Reference Amendment 0005. See the Government’s response to Question 9.

94. Reference “Section 48 19 26, Item 2.10: Please provide qty, brand and model number of existing brushes and brush holders. Also can you provide mechanical drawing of collector ring that shows mounting of the brush holders.”

Answer: Reference Amendment 0005. See the Government’s response to Question 27. The brush holders are GE part # 4979813-3 and the brushes are Carbon Products Operations (now Morgan A&T) part #2444711.

95. “Solicitation, Page 18, Volume I – Factor I, 4.1 Past Performance - Submission Requirements. All current evaluation factors under Factor I are installation related. This will ensure good quality and performance of the removal and installation work. However, there is not a single performance evaluation factor related to the Excitation System equipment itself. Hence, an installation contractor that qualifies under the current evaluation factors, could use an excitation system that the government has no previous experience with. The government technical specification for the Excitation System is different compared to other utility customers and there is a great deal more documentation requirements related to the Excitation System. Using an Excitation System manufacturer that has no previous experience with USACE projects, would increase the risk of unsuccessful performance for the project. It is suggested that a past performance factor for the Excitation System equipment is added to both guarantee that the proposed system has a past performance with USACE with a similar scope and that the past performance feedback on such projects are evaluated. Alternatively, a modification can be done of the last paragraph under 4.2 Evaluation Criteria: “Additionally, projects that are “similar in scope” and “similar in magnitude” and demonstrate experience with one or both of the following may will receive additional consideration: • Designing, manufacturing and installing a fully static, digital excitation for a USACE project; and/or • Developing and implementing an asbestos abatement plans associated with power plant excitation system removal and abatement of asbestos in accordance with approved plans and local, state, and federal regulations.” We believe that this modification will ensure that the government receives qualified proposals for both the on-site labor and the supplied excitation equipment.”

Answer: These suggestions are noted. The Government is comfortable with the evaluation factors as they stand, however, and will not be changing them.

96. “Solicitation, Page 407, Section 48 19 26, Paragraph 2.11 Please provide part number information on the existing brushes and holders. Also, please provide estimated number of brushes/holders for the uprated generator.”

Answer: Reference Amendment 0006. See the Government’s response to Question 94.

97. “Solicitation, Page 415, Section 48 19 26, Paragraph 3.3.3.4 Would it be possible to provide a photo of the exciter/PPT location showing the intended footprint in order to see how much of the architectural floor finish that needs to be restored after the existing equipment have been removed. Does the plant have matching tiles for use by the contractor or is aware of it the tiles are readily available?”

Answer: Reference Amendment 0005. See the Government’s Response to Question 28.

98. “Solicitation, Page 425 Section 48 70 01, Paragraph 1.4.3 Please confirm if MOD-027-1 (Governor testing) should be part of this excitation contract.”

Answer: Reference Amendment 0005. See the Government’s response to Question 29.

99. “Contract Drawings, Page 31, E-101, Non-seg DC bus routing, Can more dimensions be provided for E-101 to indicate the estimated length of the DC bus duct on top of the generator floor plates as well as the bus extending from the top of the generator to the new exciter location. Also, a side view of the bus duct run from the generator to the Excitation System with dimensions would be preferable. Could a picture also be provided showing the existing Excitation System, Amplidyne, Rheostat and Actuator cabinet etc.”

Answer: Reference Amendment 0005. See the Government’s response to Question 30.

100. “Contract Drawings, Page 33, E-401, Unit Control Board, Please indicate the intended location for the remote HMI panel and if there is sufficient space for mounting an Ethernet switch and 24Vdc power supply in the back of the cabinet.”

Answer: Reference Amendment 0005. See the Government’s response to Question 31.

101. Reference “01 35 70, 1.3.1 “The Contractor shall provide timely patches for vulnerabilities … for all IT HW and SW provided by the Contractor within 30 days of notification.” Please confirm understanding that patching running systems is not included in the scope of work of this contract. In case of any vulnerability alert or notification after conclusion of the commissioning test: 1. Contractor will timely provide the necessary tested Patches for vulnerabilities for the provided excitation system. 2. Government will decide the real need of the system Patching

3. Government will be responsible to install or contract the installation service for the Patches.”

Answer: Prior to commissioning and acceptance by the Government, the contractor is responsible for providing timely patches for vulnerabilities. The Government is not responsible to install the patch if the system has not been turned over to the Government.

102. Reference “01 35 70, 1.3.1 Please confirm if application of whitelisting technologies for the maintenance notebook will be accepted as an alternative.”

Answer: Whitelisting is not an accepted alternative. The contract must patch the maintenance notebook if there are known patches. If a patch is known to have a negative impact to the system, then it does not have to be installed but it must be documented. Reference Specification Section 01 35 70 paragraph 1.3.1.

103. Reference “01 35 70, 1.3.12 Please confirm if this requirement is also applicable to the maintenance notebook.”

Answer: The requirement is applicable to any notebook or computer that will be used for system start-up or testing.

104. Reference “01 35 70, 1.3.12 Please confirm if Microsoft Defender is also a DoD antivirus approved software.”

Answer: Confirmed. Microsoft Defender is a DoD antivirus approved software.

Answer: There are no reports.

133. “Can you please confirm the PT & CT inputs? a. One 3-phase PT voltage input to AVR b. One 1-phase CT current input to AVR”

Answer: Confirm. Those are generator quantities.

134. “Is 37MVA (from drawing) or 46.4MVAR (from spec) required to activate the PSS?”

Answer: The intent of this question is unclear. The PSS would be enabled at a MW loading far lower than either of these referenced values. Tuning and equipment settings will be determined in greater detail after

135. “What is the magnitude of the MW oscillation ranges (rough zones) where there is substantial hydrodynamic instability due to water vortices or turbulent flow?”

Answer: The hydraulic rough zones for the units are around 18 MW to 26 MW. This information should be confirmed during commissioning by the Contractor for their intended purpose.

136. “At what load is the nominal operating output power (typical in MW and MVAR)?”

Answer: Reference Specification Section 48 19 26 Paragraph 1.1.2. Nominal operating output power can be found in.

137. “What is the typical operating voltage of the generator?”

138. “Is the generator operating voltage mostly constant at 13.8kV? Or does it has significant voltage fluctuation?”

Answer: See the Government’s Response to Question 137.

139. “What is the proposed location to place the Excitation Transformer (PPT)?”

Answer: Proposed location for the Excitation Transformer can be found in the contract drawing E-201.

140. Would the PPT be installed on the same deck and adjacent to the AVR cabinets? Or will it be placed underneath or above ground near the 13.8kV bus?”

Answer: Proposed location can be found on the contract drawing E-201. It is on the same deck and adjacent to the AVR cabinets.

141. “Are the instrument boards the only required/ source allowable source for the control room to view the AVR status? HTS can provide an additional touchscreen linked to the AVR that can provide the following: • Excitation ON/OFF • Voltage Raise/Lower Commands (for AVR & Manual Sync) • Excitation Local/Remote Indications • PSS Status • Limiter Control / Activation & Deactivation (o V/Hz Limiter o PQ, Under Excitation Limiter o FCL, Field Current Limiter o Minimum Field Current Limiter o Stator Current Limiter) • Additional Protection Functions (3rd tier of protection in case limiters and 300G fails to operate) (o Overvoltage Protection o Field Overcurrent Protection o Loss of Voltage Balance Protection) • Ability to view more specific AVR alarms in addition to what is provided to HMI alarm/event lists”

Answer: Reference contract drawings, especially ED401 and E-401, for details on instrument boards and indication. A remote HMI is also required which is connected to each AVR as described in Section 48 19 26, paragraph 2.7.7

142. “Which switching functions the current AVR has available? - HTS recommends having accessible by a Touchscreen to switch between: a. AVR Voltage Regulation (Auto Mode) b. VAR, Q Regulation c. Power Factor, Cos Phi Regulation d. Field Current Regulation (Manual Mode)”

Answer: The current AVR has AVR Voltage Regulation (Auto Mode) and Field Current Regulation (Manual Mode). The new ones also need to have AVR Voltage Regulation (Auto Mode) and Field Current Regulation (Manual Mode). VAR, Q Regulation and Power Factor, COS Phi Regulation must not be in place.

143. “Would it be attractive to have a physical excitation dashboard (for manual operation and non-electronic visual display)?”

Answer: The contract drawings and specification lay out required features. Any additional or differing features must be approved by the Government.

144. “Would a multi-function AVR touch screen be preferred in the control room?”

Answer: The contract drawings and specification lay out required features. A remote HMI is required which is connected to each AVR as described in Section 48 19 26, paragraph 2.7.7

145. “For man-machine interaction, would it be necessary to transfer AVR signals to integrate into the DCS Human Machine Interface (HMI) stations, or rather have a dedicated HMI monitor?”

Answer: The contract drawings and specification lay out required features. The meaning of this question is unclear. Specifics on implementation can be discussed and submitted for approval by the Government after

146. “What type/model of Distributed Control System (DCS) is being used?”

Answer: The current excitation system does not use SCADA or DCS.

147. “What type/model of DCS Human Machine Interface (HMI) is being used?”

Answer: The current excitation system does not use SCADA or DCS HMI.
