4. JUSTIFICATION-State the specific energy problem or objective, and specify how the proposal will contribute to the solution of the problem or attainment of the objective. Inclurte reasons for selecting the recommended approach over other siteratives. Also inclure the benefits expected to be derived from meeting the objectives or solving the problems for which the project is proposed. Outline the risks/uncertaint an (R/U), plans to minimize R/U, and basis for proceeding in face of R/U. Quantitative data should be used to the fullest extent,

Approximately 20% of the current U.S. energy consumption is used to generate electric Solar Thermal Electric Power Systems are estimated to be able to provide up to 30% electri capacity. In addition, their collection sub-systems could provide thermal energy for proc heat for decentralized (local) and/or centralized applications. Other advantages associat with these systems are:

Energy production facilities can be essentially colocated with the demand centers to be served, resulting in negligable transportation costs.

The energy sources is limitless

· The energy source is widely distributed.

The conversion systems have minimal associated safety or waste discharge problems.

The objective of this subprogram is to demonstrate solar thermal system capability to provide widespread production of load following electric energy, with a potential for meeting baseload requirements for electric utilities, and total energy systems for military an other installations. The subprogram plans to generate more than 15e from pilot plants br FY 1979 and a total of more than 125Me from pilot and demonstration plants by Y 1984. T demonstration of a Total Solar Energy System for an Industrial Load Center project is not provided for in this subprogram. It is contained in the accelerated subprogram. Other projects are stretched out and reduced in scope and funding in comparision to the accelerat program.

Capital equipment costs have been estimated at $4.50 - 800/Ke of installed capacity for load following electrical systems. The cost for generating conventional peak power is estimated to be 25-45 mills/H in the Southwestern U.S., slightly higher costs are estimated in the Southeastern l'.S. The estimated useful life of all systems is 25 years. Delivered costs of $2-3/3 are estimated for total energy systems. Commercial operation and availability is estimated to occur in FY 1988, as opposed to FY 1933 in the accelerated subprogram. First year production capacity is estimated to be two 500 We plants.

Implementation of this plan will stimulate several industries. These include:

gless or plastic sheets (for reflectors-approx. 6 months output of one float glass line per 100 e capacity)

aluminum and silver coating (for reflectors-approx. 50 tons of aluminum per 100 Me capacity)

heat pipes (potentially incorporated in systems for heat transmission)

Several system

There are no fundamental technical barriers requiring basic research. concepts will be tested to verify overall performance and economics. A major factor presently limiting performance is the low plant capacity factor (estimated at approximately 33%) unless thermal storage is provided. Efforts are currently underway to define the technical and economic parameters of a variety of solar thermal conversion concepts. There are also ongoing sub-system and component R&D activities including development of scale model collectors and high efficiency solar absorption coatings. In addition, the entire Solar Total Energy Concept is being examined and assessed at NSF, AEC, and DOD laboratories, and under DOO contracts.
