The California State Water Project — Asset Management and Condition Assessment
The California State Water Project (SWP) is one of the largest water and power systems in the world. It conveys, on average, 2.4 million acre-feet of water annually to 29 long-term water contractors through 20 pumping plants, 8 hydroelectric power plants (includes 3 pumping-generating plants), 25 dams, 34 reservoirs, and more than 700 miles of aqueducts and pipelines. The SWP is also the largest consumer of energy within California. The California Department of Water Resources (DWR) is charged with managing, operating, and maintaining the SWP. With over 150 large hydro units and associated supporting equipment to operate and maintain, DWR recently adopted an Asset Management Plan to permit high-level proactive budgeting of all future SWP projects. Fundamental to DWR's Asset Management Plan was development and subsequent implementation of a Condition Assessment Program (CAP). Consistent and regular condition assessment of SWP plant facilities ensures equipment health for an aging system (35+ years) and enables DWR to operate and maintain the SWP at high levels of operational availability (OA). High OA is critical to DWR since California operates in the deregulated (in 2001) energy market. Unscheduled or prolonged scheduled outages can result in lost opportunities for generation revenue and/or increased costs for daytime pumping. DWR's CAP has three primary planning objectives: 1) long-term — objectively identify future SWP projects for proactive budgeting (1- to 5-year budget cycle), 2) medium-term — enable maintenance resources to embrace and move toward a Reliability Centered Maintenance philosophy, and 3) short-term — identify projects/equipment that may require immediate maintenance. The DWR CAP divides a hydro facility into five equipment groups (Unit, Transformer & Switchyard, Balance of Plant, Communications & Controls, and Waterways), and each equipment group undergoes rigorous inspections (visual, functional, reliability, and test) to determine the overall condition of a facility or plant. Detailed rating guides ensure that equipment condition scores are objective and repeatable. The rating guides detail how to score all equipment regardless who is conducting the CAP inspection. The end result is a plant condition score that enables management to determine where to allocate maintenance resources and future funding. Collected data that is not current (five or more years old) will result in a low confidence score, which indicates that maintenance is not being performed, not being documented, or a combination of both.
