Turbine/Generator – Guaranteed Performance Worksheet

Bidder guarantees the turbine and generator performance as completed in the table below. Bidder shall compete table with the following directions. (1) Bidder inputs guaranteed turbine efficiency and generator efficiency at each condition. (2) Bidder calculates Turbine Generator Output (kW) = Turbine Discharge (cfs) x Net Head (ft) x Turbine Efficiency x Generator Efficiency / 11.8 (3) Bidder calculates Annual Generation (MWh) = Turbine Generator Output (kW) x (Percent of annual hours at condition) X 8760 / 1000. Round to the

nearest whole number. (4) Bidder provides estimated runaway discharge and estimated speed at each condition. (5) Bidder sums the annual generation at each condition to arrive at the Total Annual Generation. Divide. Use the total annual MWh generation to compute

the deduction for Bid Item No. 11.

Question Answer

1 How is SCOOP content valued in bid evaluation? See Contract Documents, Notice Inviting Bids, Section 3, and Instructions to Bidders, Section 3.0.  Schedule A‐1, Designation of All Subcontractors, including Subcontractors/Vendors/Service Providers is to be completed and submitted as part of bid.

2 Is there a possibility to provide a lower voltage system, maybe at 480V or 2400V, with a GSU transformer to provide additional generator protection?

Provide 12kV generator per the Contract Documents.  See Addendum 3 for allowable alternate grounding methods.

3 Section 11200, Turbine, Part 2.02, Paragraph A.  The old IEC 193 1965 Edition contained an Amendment 1, but the current IEC 60193 does not contain an Amendment 1. Can you please clarify?

See Addendum 3 for updated standard references.

4 Section 11200, Turbine, Part 1.07, Paragraph C, Item 4. Can you please explain the significance of the “Existing conditions” and “FRS II conditions”? Additionally, is the turbine expected to operate down to heads as low as 150 feet?

The upstream headwater elevation will permanently change in the near future as a result of another project named "FRS II."  The two hydraulic conditions in Section 11200, Turbine, Part 1.07, Paragraph C, Item 4 represent the current conditions and future conditions.  The turbine is required to operate within the conditions defined in the Contract Documents.

5 Section 01640, Supplier's Services, Part 1.01, Paragraph A. IEC 60041 is not applicable to small hydro and IEC 62006 should be used for machines with unit power up to about 15 MW and reference diameter of about 3 m. Can you please confirm or clarify which standard we are to work to?

See Addendum 3 for updated standard references.

6 Section 01640, Supplier's Services, Part  1.06, Paragraph A states “The General Construction Contractor will direct and perform start up and commissioning for all systems for the Project. The General Construction Contractor will provide or coordinate the equipment and labor to perform field tests required to validate the performance of the supplier equipment.”IEC 60041 states:4.3 Personnel ‐ The selection of personnel to conduct the test and procedures in connection therewith are matters of prime importance.4.3.1 Chief of test ‐ A Chief of test shall be appointed by agreement between the two parties. He should be competent to supervise all of the calibrations, measurements and calculations necessary to determine the performance of the machine. He shall exercise authority over all observers. He shall supervise the conduct of the test in accordance with this standard and any written agreement made prior to the test by the contracting parties. He shall be responsible for the calibration of all test instruments and for all test measurements. He shall report on test conditions and be responsible for the computation of results including the determination of the measurement uncertainties and the preparation of the final report On any question pertaining to the test his decision, subject to the provisions of 4.5.1,4.7.6 and 4.9.1, shall be final.4.3.2 Choice of personnel ‐ The testing team shall have the necessary competence and experience for the correct installation and utilization of the measuring equipment.“The two parties” refer to the supplier and the purchaser. How does the supplier ensure that the General Contractor will provide suitably qualified labor?

Refer to Section 01640, Supplier's Services, Part 1.04 for Supplier's responsibilities including providing  staff to witness and validate the General Construction Contractor's installation and testing.  Section 01640, Supplier's Services, Part 1.04 includes requirements to notify the Engineer in writing if work is being performed contrary to Supplier's instructions.

7 Section 01640, Supplier's Services, Part 1.06, Paragraph E.  Could you please explain the proposed method of flow measurement, as the drawings provided in Alvarado Pre‐Procurement Bid Set.pdf do not show any suitable location for accurate flow measurement in accordance with IEC 60041?

The General Construction Contractor will install a Venturi flow meter upstream of the turbine that will be used for testing.  Refer to Drawing I‐3 which identifies this meter as instrument FE‐001.
