SECTION 2.0:PROJECT DESCRIPTION month or year will depend on weather-related customer demand,load growth, hydroelectric supplies, generating unit retirements and replacements,the level of generating unit and transmission outages, and other factors. The exact operational profile of the plant will be dependent on weather conditions and the power purchaser's economic dispatch decisions. The facility could be operated in one or all of the following modes: • Base Load.The facility would be operated at maximum continuous output for as many hours per year as dispatched by load dispatch. During high ambient temperature periods when gas turbine output would otherwise decrease,duct firing by steam injection into the combustion turbines may be used to keep plant output at the desired load. • Load Following.The facility would be available for full load but operated at less than maximum available output at high load times of the day. The output of the plant would, therefore,be adjusted periodically,either by schedule or automatic generation control, to meet whatever load proved profitable to the power purchaser or necessary by the California Independent System Operator. • Full Shutdown.This would occur if forced by economic conditions, equipment malfunction,fuel supply interruption,transmission line disconnect,or scheduled maintenance of equipment common to all units. In the unlikely event of a situation that causes a longer-term cessation of operations, security of the facilities will be maintained on a 24-hour basis, and the CEC will be notified. Depending on the length of shutdown, a contingency plan for the temporary cessation of operations may be implemented. Such contingency plan will be in conformance with all applicable LORS and protection of public health and safety, and the environment. The plan, depending on the expected duration of the shutdown,could include draining all chemicals from storage tanks and other equipment and the safe shutdown of all equipment. All wastes will be disposed of according to applicable LORS. If the cessation of operations becomes permanent,the plant will be decommissioned (see Section 2.7,Facility Closure). 2.4 Engineering In accordance with CEC regulations,this section,together with the engineering appendices and Section 4.0 (Natural Gas Supply),presents information concerning the design and engineering of the LEC facility. The LORS applicable to the engineering of the LEC are provided along with a list of agencies that have jurisdiction,the contact persons within those agencies, and a list of the permits that will be required. 2.4.1 Facility Design Design and engineering information and data for the following systems are found in the following subsections of this Application for Certification: • Power Generation—See Section 2.1.6.1, Combustion Turbine Generators. Also see Appendix 213 and Section 2.1.15,which describes the various plant auxiliaries. • Heat Dissipation—See Appendix 2B. 2-34 SAC/371322/082340003(LEC_2.0_PROJECT_DESC.DOC)
