The preliminary plant design for a compressed-air energy storage (CAES) plant located in the Middle South Services, Inc. (MSS), is presented. The design is based upon the facility criteria; the specific site; and the systems, subsystems, and components identified in the other task of this study. The proposed 220-MW(e) plant is located at the Carmichael salt dome near Jackson, Mississippi. The compressed air is stored in two solution-mined caverns in the salt dome. The plant area, exclusive of the remote fuel unloading facility, occupies 20 acres. An equipment list, a plot plan, and general arrangement drawings define the CAES plant. The details concerning the major equipment and the operation of the mechanical systems are described. The capital investment cost (exclusive of owner's cost) of the 220-MW(e) CAES plant is $85.6 million in 1979 dollars or $389/kW. This cost is based on firing the turbines with No. 2 fuel oil. As an alternative, the capital investment cost under the same conditions for a plant firing No. 6 oil is $90.9 million or $413/kW. The project schedule from start of licensing to commercial operation is estimated to be 70 months, with actual construction (including dewatering of the caverns) estimated to be 39 months. Based on the cost estimate developed in this task and the modified financial data and fuel cost projections, the economic introduction of CAES into the MSS system was examined for the No. 2 oil-fired plant. Due to lack of funds, the economic analysis did not extend beyond the year 1988. No system analysis of the No. 6 oil-fired plant was made. The economic introduction of CAES in the MSS system before 1990 is unlikely because the older oil-fired units in the MSS system may be economically used for cycling and peaking, if required. For a system with a different composition of generating units (i.e., low-cost, coal-fired plants), CAES may be economical at an earlier date.
