Concepts for solar thermal central receiver plants have evolved through continuing research and development into designs that are projected to have higher efficiency and lower cost. Recent studies have combined these results with rising costs of fossil fired plants and fuels to show that solar central receiver plants can be a competitive alternative for large scale electrical production. Because of these findings, commercialization of the concept is now receiving increased attention by both government and private groups involved with development of the technology. Elements of a government program to achieve successful commercialization by the early 1990's are recommended. The recommendations integrate utility requirements for demonstration and risk sharing with supplier needs for manufacturing process development. Program timing and costs are presented, and the effects of program modifications are briefly discussed.
