WorleyParsons <br /> resources&energy <br /> • (1) CEMS building <br /> The plant will be designed for an expected reliability of 92-96 percent over a 30- <br /> year life. <br /> Site layout and design, including underground utilities, will be done to <br /> accommodate future noise barrier walls along with their foundations,to be located <br /> at exhaust duct inlet transition, and all four sides of the gas compressor. <br /> 1.2 Operating Mode and Basic Philosophy <br /> • Operational flexibility and high reliability are of paramount importance. <br /> • The plant will be designed to run on a continuous basis between maximum plant <br /> output and the minimum load at which emissions guarantees are met which is <br /> typically 50% of a CTG output. In other words, to be emissions compliant, the <br /> CTG will be required to generate at least 50% of the machine capability to be <br /> emissions compliant. <br /> • The CTG will be designed to achieve short duration starts, typically 40-60 <br /> minutes from initiation of starting sequence to full load. <br /> • The plant will not be designed to generate electricity while isolated from the <br /> utility grid. The anticipated number of operating hours per year is about 6800 hrs <br /> • The BOP equipment and systems will be designed to support the start up times <br /> listed above. <br /> • The plant control system design will be based on a Distributed Control System <br /> (DCS) utilizing both discrete I/O as well as dedicated packaged equipment PLCs <br /> such as separate PLC's for gas compressors, CEMS, and air compressors. <br /> • The CTG, STG, and other BOP equipment will be operated primarily from a work <br /> station in the main plant control room located in the administration building. <br /> • The power block will be designed so that it can be started and operated at any <br /> load by a single operator. <br /> 1.3 Redundancy in Design <br /> Standby components will be provided for key auxiliary components that would <br /> cause an electrical production shut down by their failure. The stand by <br /> component will be installed and kept in a ready status for immediate service. <br /> Lodi Energy Center 3.1 -2 LEC AFC <br /> 071708 Rev.A <br />
