Title
Approval of the Expenditure and Issuance of a Purchase Order for Services Agreement No. AGR 25-925 with Andritz Hydro for the Purpose of Repairs to the Abiquiu Hydroelectric Plant Draft Tube
Recommended Action
I move that Council approve the expenditure and issuance of a purchase order for services agreement No. AGR 25-925 with Andritz Hydro, for the purpose of repairing the draft tube elbow and engineering and supplying the air admission piping in the amount of $538,500.00 and a contingency in the amount of $61,500.00, for a total not to exceed $600,000.00, plus Applicable Gross Receipts Tax.
Utilities Manager's Recommendation
The Utilities Manager recommends that Council approve motion as presented.
Board, Commission or Committee Recommendation
The Board of Public Utilities approved this request at their regular meeting on April 16, 2025 and recommends that Council approve motion as presented.
Body
The existing draft tube on unit #3 in Abiquiu has been experiencing wear from cavitation created by the dissolved oxygen injection system. The injection system forces air into the discharge water to enhance the oxygen content of the plant discharge to sustain aquatic life. The injection piping obstructs the discharge flow and creates cavitation that has worn through steel draft tube. These funds will be applied to repair the damaged section of the draft tube and install a new aeration intake system.
Alternatives
If the Council does not recommend the expenditure and issuance of a purchase order with Andritz Hydro, staff will not be able to repair the draft tube and will be unable to run this Hydro generator to produce electricity.
Fiscal and Staff Impact
The project has been budgeted through Electric Production in FY 2025 in the amount of $600,000.00. There are no additional staff impacts to perform the project.
