The program of innovative technology procurement is a government program designed to introduce and promote energy-efficient products and systems. This program has now been in effect in Sweden four years and appears to be successful. This paper deals with different procurement projects, such as the refrigeratorj-freezer, the 4-pane window, high-frequency lighting etc. It discusses the process, how it is started, with whom and with what. With different projects as examples, we discuss what type of support the process needs, such as experts, demonstration, standards and information. The ultimate goal of the process is to produce a market transformation, i. e. to consolidate and strengthen market forces which increase the production, acceptance and distribution of more energy-efficient technology. The paper also discusses the difficult issue of how much of the market transformation can be attributed to the procurement program and how much would have taken place without the program. It also deals with the issue of how cost effective the program has been. Finally, we discuss briefly the problem of measuring total market transformation.
