(URGENT NEED)

Headgate Rock Power Plant Hydroelectric Generation Unit Exciter Controller Replacement

1.0 BACKGROUND

Owned and operated by the BIA, the Headgate Rock Dam (HGRD) is located on the lower Colorado River, about 15 miles downstream of Parker Dam near the town of Parker, Arizona. The dam, which impounds a body of water known as Lake Moovalya, has 10 radial gates. Radial gates #1-7 act as spillway gates and pass Colorado River flow without generating any power. Radial gates #8-10 sit immediately upstream from the power plant’s three hydroelectric generation units. The hydroelectric power plant was retrofitted to the Head Gate Rock Dam (HGRD) circa 1992. It was designed as a low head, axial flow turbine powering the generation units to nearly 19.5 Mega Watt (MW) of power serving the Colorado River Indian Tribes (CRIT) Reservation. Somewhat rare, the hydroelectric generation units are installed horizontally because of the low head design. The turbines were manufactured by Allis- Chalmers/Voith and the generation units are manufactured by Villares.

Currently two of the three turbines at the HGR-EGS are inoperable due to the failed legacy governor controllers on Units #1 and #3, leaving no way to control the hydraulic governor system. Unit #2 is currently operable utilizing the same governor controller; however, it is past it’s useful lifecycle. The Bureau of Indian (BIA), Colrado River Agency, Electrical Services (CRA-ES) have attempted to source third-party services and vendors to procure parts and repairs services. The vendor procured and partially installed Siemens hardware but was unable to successfully install and commission.

2.0 OBJECTIVE

The power generated at the HGR-EGS is a cornerstone to meeting the BIA’s mission of Tribal self-determination for the Colorado River Indian Tribe (CRIT). A key goal for BIA, CRA-ES is to provide economical and reliable power to the residential, commercial and irrigation customers that reside within the boundaries of the CRIT reservation.

The recent governor controller failures have caused a loss of power generation with the last generator experiencing intermittent problems with its 505 controllers. Therefore, the objective for this urgent requirement is to properly install, configure, migrate, integrate, network, program, and commission the Government furnished Siemens controllers for HGRD turbines.

Due to the urgent requirement and the failed previous attempt to commission the governor controllers, CRA-ES seeks to utilize the expertise of the OEM for this effort.

3.0 SCOPE

The scope of this effort is to perform the necessary tasks to successfully install, configure, and commission the Government furnished Siemens S7. Additionally, the contractor shall procure and configure a complete operable spare S7 controller. If parts, components, and/or sensors are missing, the contractor shall procure those for commissioning and the spare controller as well. The contractor shall supply all tools, equipment, materials, management, labor, training, and Subject Matter Experts (SME’s) required to successfully replace the failed Woodward 505 controllers. The successful installation and commission shall ensure the hydroelectric generation units operate within the Voith specified parameters for the turbine.
