ABSTRACT:
This report establishes standard descriptions for solar thermal power plants and develops uniform costing methodologies for nondevelopmental balance-of-plant (BOP) items. The descriptions and methodologies developed are applicable to the major systems under development within the U.S.
A detailed description is given for the BOP category. BOP contains a number of nondevelopmental items that are common to all solar thermal systems. A standard methodology for determining the costs of these nondevelopmental BOP items is given. The methodology is presented in the form of cost equations involving cost factors such as unit costs. A set of baseline values for the normalized cost factors is also given. These baseline values were selected for use in making comparative assessments of different solar options. For determining the BOP costs for a particular plant at a specified site, the various cost factors must be chosen to meet site-specific requirements. The basis for the derivation of the cost equations and the rationale used in selecting values for cost factors involved in these equations are discussed. An example using the derived BOP methodology is also presented.
Future evolution of the BOP methodology is suggested. The development of scaling techniques for use with certain BOP items, establishment of BOP cost differences among different technologies, and implementation of probabilistic costing methods for an entire power plant are some of the recommendations made for future work.

Department of Energy (DOE) Solar Thermal Program. These systems include the central receiver, parabolic dish, parabolic trough, hemispherical bowl, and solar pond. The standard plant is defined in terms of four categories comprising (1) solar energy collection, (2) power conversion, (3) energy storage, and (4) balance-of-plant (BOP). Each of these categories is described in terms of the type and function of components and/or subsystems within the category.A detailed description is given for the BOP category.
