Statement of Work HGRD Replace UPS System and Power Inverter

Bureau of Indian Affairs / Colorado River Agency / Electrical Branch

12124 1st Ave, Parker, La Paz County, AZ 85344

1.0 INTRODUCTION

The Bureau of Indian Affairs (BIA), Colorado River Agency, Branch of Electrical Services (CRA-ES) is in the need of a replacement UPS System and Power Inverter for the Headgate Rock Dam (HGRD). CRA-ES seeks an experienced and knowledgeable contractor to procure, install and commission a replacement UPS System and Power Inverter for the HGRD.

A key mission of the BIA, CRA-ES is to provide economical and reliable power to the residential and commercial customers that reside within the boundaries of the Colorado River Indian Tribe (CRIT) reservation. Owned and operated by the BIA, CRA-ES HGRD is located on the lower Colorado River, about 15 miles downstream of Parker Dam near the town of Parker, Arizona. HGRD, which impounds a body of water known as Lake Moovalya, has 10 radial gates in which 3 of the feed the hydroelectric power plant that 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.

The UPS provides power for the emergency lighting, fire detection, security, control system computers, microwave transceiver, electronic phone system, logger/printer, and power to Inverter. The power inverter is located on panel C2B and it supplies power for the Supervisory Control And Data Acquisition (SCADA), Remote Terminal Units (RTU) A and B, RTU A and B sub-nodes, RTU panel lighting, remote pressure level sensors power support. The UPS system and the Power Inverter are key components of the control systems for the HGRD power plant.
